What's the most dangerous kind of monster out there? The answer seems obvious, right? Those ranked at S level. Vampires, werewolves and the like. They're super strong, super fast, super destructive, super durable. When it came down to a fight, your best option was to not. Because even running couldn't guarantee survival. Perhaps the answer isn't so simple as rankings.

It was the holiday season, and Yokai Academy was closed up. Like most schools in the modern era, Yokai had itself an IT department. Computers were becoming increasingly important within the human world, after all, so it was rather important, nay, essential for them and their students to comprehend the meaning behind these things.

Cue a wiry-haired young man with bottle glasses. He didn't actually need them. The inside of the glasses merely projected the outside world in full through a concealed camera. It was just, you know, this was the image he understood people in his profession presented in the real world.

"There!" he announced to nobody in particular. "The school's security is now top of the line. Even an electrical monster couldn't hack through this. Every precaution has been taken, and now the school will be ready to tackle the new year! Hohoho!"

He stretches, he swivels out of his seat, he stretches some more and then he strides out of the school with hands stuffed in pockets. Yes, indeed. Today was a solid day's work. He had set up the perfect security system, even accommodating for the abilities of numerous monsters that might try something devious. Nobody was getting into the secure files, not one person!

Except, as anyone with security expertise in the real world will tell you: No matter how good the system, its weakest point will always be the people using it. Now, while it would be rude and unfair to say that someone typically nerdy enough to be an IT professional is easy prey for an attractive woman, the fact of the matter is, it's pretty much true. On the opposite side of the spectrum, it would be completely fair to say that a succubus could easily seduce her given target almost every single time, with just a few exceptions. The union of these two thoughts means that a succubus attempting to seduce an IT professional is equivalent to hunting rabbits with a bazooka. Or two big, bouncing bazookas. Either way there's going to be an explosion and fluids will be spilled.

"Ohh, my stomach!" moaned an attractive woman wearing a business suit, leaning against a wall and clutching at her stomach. "I shouldn't have eaten that chicken... Someone, help me! Please!"

Mister IT looked around nervously. It was only him and her out and about just now. The part of him aware of monsters was telling him to be wary. She could be a vampire out for his blood. Or she might be intending to eat him whole.

On the other hand, even with the way she was bending over he could tell she had an astounding rack beneath that unflattering suit. Libido overruled common sense, and so he moved in.

"Is something wrong, miss?" he asked warily. She moaned again in obvious agony, and sunk to her knees. "H-Hey, it's alright! Do you need a doctor? I can call for a doctor on my phone."

"N-No," she shook her head. "Just- Just help me get home. It's right around the corner, but I can barely stand. Ohhh! Please help me! Please, sir, please!"

Well, he could hardly refuse now, could he? With a trembling hand, he reached out for the mysterious woman's arm and used what little strength he had to help pull her upright. Then, suddenly she seemed to collapse into him, pressing her chest up against his. Impressive bust: Theory confirmed. "Thank you," the woman said, slowly lifting her gorgeous face to look him in the eyes. "If you hadn't come to help, why, I'd have had to use this prepared mixture to make it look like I'd thrown up."

"Huh?"

And then she made eye contact. They were beautiful. If you'd asked him what colour they were right there and then even as he was staring into them, he couldn't tell you. They were every colour, no colour at all. Shimmering. Shifting. Never the same, always moving along the spectrum, dancing around to a silent rhythm. She batted those beautiful eyes at him. For him. It felt like they were swallowing him whole. Then he felt her hands resting on his elbows, gently pushing his arms so that his hands slid down her back. Taking it in. Her body. Under that suit. Resting on her butt beneath an unflattering pair of trousers. It might be a little rude, but he couldn't stop from stealing a squeeze. Based on what he felt, he wouldn't even regret it if he dropped dead right now.

"Help me home, won't you, handsome?" the woman asked, and all he could do was nod. She shifted her grip so that her head was resting on his chest, and her wonderful body was pressed completely up against his side. Paradise. He was in some kind of paradise, without question.

Inexplicably, her home had the same address as his. That got him blinking a bit, but she seemed to notice this and ran her finger seductively across his chest. That made him stop thinking. Thinking was bad. Enjoy the moment. Let her inside.

The instant the door was closed behind them she disentangled, strode forward and tugged off her trousers in a sharp motion. They weren't actually office trousers. They were breakaway trousers that looked like office trousers. The mystery of this was lost on him as he beheld the delight of her bare legs and a thong covering precious little of her shapely ass.

"Nice place I have here," she said, reaching up to her neck and tugging down a zip. Revealing bare back, inch by glorious inch. "It could do with a little dusting, a little tidying up... But it should do, until school begins."

"H-Huh?" Mister IT asked, unable to shift his eyes from her glorious body. It was perfect. Every inch, every molecule, every everything. He could feel the strain on his dick. It was yearning for freedom! More than that, it was yearning to touch her. Not necessarily dirty her by being inside her, just touching her skin would be enough.

She turned around and removed her wig, revealing blue hair. Blue hair like the sort a succubus might have. That triggered... Something in the back of his mind, but damned if he could figure out what it was. Any man that could think clearly when a succubus was standing in front of them wearing naught but a silver string bikini had no interest in the opposite sex at all, not even a grain.

"You're in charge of IT for Yokai Academy," the succubus stated. Not a question, a statement. She walked right up to him and hooked her glorious, magnificent, perfect, flawless leg around his insignificant, inferior waist and wrapped her hands around the back of his head. "That means you have access to secure data. Like... Say... What monsters the staff and students are. For example."

He nodded. Yes, he had access to those files. He never had cause to read them usually. Yet it was well within his ability.

"When are you next scheduled to head into school?" she asked. Eye contact made. She was even more beautiful than he remembered, which should be impossible and yet...

"Tomorrow," he answered honestly. She batted her eyes and leaned closer. Oh, this close made even her previous beauty pale in comparison! By now his entire body was trembling. Every bit of him that she touched felt good even if it was through clothes. "I'll be back tomorrow."

"Good boy," she whispered. "So... If you take me in tomorrow... If you let me see those classified files... Do you know what kind of reward you get?" He shook his head. "Why, it's obvious. You get to be the first member of Kurumu Kurono's harem of sexy boys and girls. Doesn't that make you feel special? Stud?"

It did. And now we must answer that initial question. What's the most dangerous kind of monster out there? The answer is, whichever one is able to use their powers to their absolute advantage the most intelligently. And it seemed as though this time around, Kurumu was a veritable genius.

Chapter Text

Being a security guard is a thankless job. Would it surprise you to learn that the most troublesome aspect was boredom? The tedium? Because that's the thing about security, in fact that's the thing about most working systems in general. You don't notice it's working when it's working right, no matter how hard it's getting done. Well, that's what makes security so boring. Nothing happens almost every night, but you never know when something might kick off so you have to be constantly ready, constantly diligent, otherwise something might just happen under your nose and if it does then your neck is on the line.

No different at a school for monsters. Some students got the bright idea of trying to sneak in and directly access the school's computer systems for all sorts of nefarious purposes. Changing grades or looking up information they shouldn't have access to. Or maybe they'd try sneaking into the chemistry department for whatever reason, or they wanted to vandalise their least favourite teacher's office.

He sniffed the air. Actually there were some differences to human schools. Namely, some monsters could do things like "become invisible". Which meant you had to have a security team capable of dealing with foibles like that. Take him for example. He was your typical dog-demon. Keen sense of smell, naturally stronger and faster than your average yokai. The ideal security guard for a school of monsters.

That didn't keep him from getting bored, but that was another issue entirely.

All of a sudden he hears a noise. Check the camera. Ah, it's just their IT guy coming in through the back way. Possibly left something behind, or figured out the solution to a tech problem and simply couldn't wait until morning to see it through. Well, whatever. He smelled normal and he had permission to enter.

Neither of those qualities could be ascribed to the young woman oozing in after him. She was a looker, he could say that much for certain. Distinctive blue hair. Wearing a pair of glasses which, he could plainly tell, didn't actually have any glass in them. She also had a labcoat on, a pair of sneakers, some thigh-length socks and beyond that it was impossible to say. She strutted her way in like she owned the damned place, rocking those hips to and fro in the cockiest of the walks this particular dog demon had ever seen in his life.

"Succubus," he said after sniffing the air. "Probably ensnared the dope with a charm spell. The dork is always going on about how people are the least secure part of any system..."

Which left him with an interesting conundrum. It was the middle of his shift. He was by himself. Going out there to confront a succubus and her thrall didn't seem like the smartest move. Actually, it seemed like the most surefire way to get himself snared up as well.

He drummed his fingers on his desk. Then he picked up the phone - and heard it ring.

"Hello?" he said.

"Hi, cutie," a woman's voice said. He turned to the monitor. The succubus was staring into the camera. He quickly averted his eyes, just to be on the safe side. "Just so you know, I'm not going to be hanging up. Your phone line is going to be all tied up with li'l old me. Come catch me, big boy. Better hurry. I'll be gone in ten."

He hung up the phone on his end when she started to use an obviously exaggerated girly laugh. The cheeky little - So he couldn't call out for support and whatever they were up to wouldn't take long at all! She was baiting him into coming after her.

Worse than that she'd indicated what she was up to would hardly take any time at all. She'd be gone and done by the time support arrived, and he'd be given the sack for sitting back and letting it happen without trying to apprehend or stop them.

So he bucked up and watched the monitors. The girl was sitting at a computer, stretching out her arms while her slave waited outside the room, waiting and watching with his back to the door. Again, the plan was obvious. If he tried entering the room she'd hit him with her charm the second she made eye contact. If he went through the door, he'd have to go by the slave. Meaning that she'd hear him, meaning that she'd be focusing her full attention on the door. Since the monitor in the office was turned with its back to the door, she'd already be looking that way. Clever. Prepared, too.

But not clever or prepared enough.

He went out through the front door at a tremendous speed. Rushed around the building. Keys in hand. Back pressed to the outer wall. With a tremendous smirk he peered inside the room, through the window. Just a glance was enough. There she was. Back turned to the window. He slowly put the key into the lock, turned it just so - and at the same instant that it popped, he pulled it open and aimed his firearm directly at the back of her pretty little head.

"No sudden moves," he warned. "I know you're a succubus, and I know about your charm! That's not going to work on me. So why don't you start by telling me what you thought you were trying to do?"

"You know about charm?" the succubus asked. "Really now? People say that, but they don't really get it. Although that does make sense. I'm the only one who has really experimented with it."

His eyes narrowed. Something wasn't right here. Something on the edge of his peripheral vision, but he couldn't quite place what it was. "Experimented?" he asked. "The hell are you -"

"I mean, its effects always seemed so obvious," the succubus sighed. "Ensnare men into doing your will. Doesn't work on women. Unless they are gay. Doesn't work on gay men either. You see, it's a bit more complicated than that - Ah, I'd show you but that would mean turning around and you don't want me to do that."

"Enough chit-chat. Order your slave to tie you up and wrap something around your eyes, or I'm going to pull the trigger, fill out a form and get off scot free."

"No, you won't," she sang. "Get off... scot free. But you will be getting off. Aren't you curious about what I was doing on this computer? Go ahead. Take a look. Take a long look."

And then he saw it. What was bothering him. She had been typing away at the keyboard, but... The monitor wasn't even on. It was completely black. The succubus leaned forward just a scooch, and all of a sudden her face became clear as crystal in the reflection on the screen.

Her beautiful, perfect face with the most enrapturing eyes he'd ever seen.

"One thing I discovered? Reflections work just as well as direct eye contact."

The gun dropped to the ground. She stood up. Like a goddess towering over him. He fell in through the window at her feet. Her perfect feet underneath perfect legs, perfect hips, perfect...

"The other thing is that Charm doesn't actually brainwash anyone," Kurumu said. She opened up her labcoat and let it slip off her body. There was nothing underneath but a silver string bikini. Virtually nothing was left to the imagination, which was just as well for his imagination was simply too limited to imagine how amazingly hot she was. "It's kind of like a multiplication factor. Whether you meant to or not, you checked me out on the cameras before and liked what you saw. All my charm did was multiply that by a factor of fifty. Assuming we were quantifying things like 'level of attraction'."

"What -" he stammered. "What is your name?"

"Kurumu," she said, putting a hand on her hip and then using it to bump the chair aside. "Now, I don't take too kindly to people pointing guns at the back of my head. I mean, I might not technically have permission to be here, but someone who does let me in. Right? And like I just said he's not actually brainwashed. He's just... Really, really turned on by my very presence - But I don't need to tell you that. You already know."

He did. And he nodded enthusiastically.

"So, as your punishment..." Kurumu said. "Hands and knees. You'll be my chair while I work."

He couldn't get into position quickly enough. On his hands and knees in front of the desk. His tongue was hanging out like a dog sticking its head out of a window. He'd thought just then that his dick couldn't get harder, but then she sat down and his eyes rolled up into his head as her delightful rump took its rightful place on the small of his back.

She switched the monitor on and he craned his neck up. To get a better look at her body, but also because he was still curious. "What are you trying to do?" he asked. "Maybe I can help more than this?"

"Oh, that's easy enough..." Kurumu said. "The succubus race is dying out. Other monsters don't give a damn, but I have no intention of letting us go quietly into the night. This school has some of the most influential families in the monster kingdom attending as students or faculty. So... I'm going to use that resource to save my kind. I'm going to get them researching ways to make it happen. I'm going to get them to pump money into that research. And if it comes down to it, I might even pump one of them for the next generation of succubi, and start a great big family with them."

Ooh, but he hoped it was him! Probably not. He was but a lowly dog demon security guard, and she deserved something much, much greater than that! But she wasn't done talking yet.

"More specifically I'm getting all the monster data for everyone attending," Mistress Kurumu chirped. "That way I'll be able to identify likely problems and develop a longer-term plan for how to deal with them, as well as prioritise targets for my bisexual harem."

"But mistress!" he called, and Kurumu quite deliberately squirmed. He shuddered in pleasure. "D-Didn't he tell you? That file is securely protected. Nobody, not even the principal can print it off or create copies. It's - It's part of the hardware, you won't be able to take that out of here!"

"And memorised."

He blinked in disbelief. What? What had she just said? Kurumu was standing up now. Dusting herself off, and to his displeasure covering herself up once again with her labcoat, tying it on nice and tight while his mouth opened and closed wordlessly.

"What?" he eventually squeaked out. "M-Memorised?"

"Uh huh," Kurumu said. She smiled at him. She actually smiled at him! And then tapped the side of her head. "All in here! Memorised to the last."

"B-But there are a hundred new students attending just this year!" he protested. "Not to mention years two and three! How could anyone ever memorise -"

She leaned down and kissed him on the mouth. In the back of his head he knew this made the charm effect permanent, but that was a long ago concern. It was honestly kind of a relief not to have to worry about it wearing off.

"First thing you're going to learn," Kurumu said. "Is my recipe for success. A perfect body, and a perfect mind. Now. That file didn't contain the home addresses for the other members of the school's security team. You wouldn't happen to have that on hand... Would you?"

Chapter Text

Tsukune had been hyping himself up for quite some time about his first day at this new school. He'd never actually heard of Yokai Academy before, and the boy was quite eager to see how he fit in. None of his friends were going, nobody in his family had ever heard of the place before. It all came down to his father randomly finding a brochure, thinking it sounded cool, and then he was booked for it just like that. No interview, just a weird little form to fill in and they accepted pretty much right away.

Which, to his mind, sounded just a little too good to be true. No entrance test for such an exclusive school? And there were parts of the form that just did not sit right with him at all. Sure, it all looked about right with all the usual details required. Name, gender, race, a larger box to fill out any special needs. Yet there was something about it all that felt somewhat sinister, something he must have noticed subconsciously but couldn't quite work out for the life of him.

"Good evening Mister Aono."

Yet those concerns were quickly crushed under the stampeding fresh worries brought to life by the corpse-like appearance of the bus driver that had arrived to take him, and only him, to this brand new school. He took a tentative step onto the creepy, ramshackle old vehicle -

"Ah, please wait! I'm here, I'm here!"

Then stopped as he heard a girl rushing after them. Tsukune turned around and boggled. There was a really cute girl rushing after the bus. Vibrant bright blue hair tied back with a purple maid headband, a pretty face hiding behind a thick pair of glasses. She was wearing a rather tight fitting jumper, plain colour but you'd be hard pressed to remember the colour with those mounds sticking up the fabric. She was also wearing a rather short pleated skirt that showed off a killer set of legs.

At first glance, Tsukune could only blush and force himself to look away. She was really, really pretty. Strange though, he'd surely remember seeing a beauty like that wandering around wouldn't he?

She reached the bus and leaned against Tsukune to catch her breath. It felt almost like she was stealing his to manage it! Oh boy, he could feel them pressing up against his arm. Gulp!

"Kukuku... How adorable," the bus driver cackled ominously. "Well then, young lovers. Get in, and I shall take you to your destination. Tsukune Aono and Kurumu Kurono, please board now."

"Phew, just made it!" Kurumu sighed. "Um, after you. Tsukune, right?"

"R-Right!" he said nervously. Oh gosh. He couldn't even bring himself to look at her right now. Tsukune sat at the back of the bus feeling his heart going aflutter. He hadn't expected that! After a moment Kurumu followed him onto the bus, and shyly approached the back. So cute! The little way she was fidgeting as she stepped towards him. Wait, was she intending to sit at the back with him? No way, why would a girl like that want to -

"Kya!" she yelped, and fell right into his lap. Tsukune caught her reflexively, holding her by the shoulders.

"Are you alright?" he asked.

"Oh, I'm perfectly fine," Kurumu said, taking off her thick glasses as she spoke then looked him right in the face. "Wouldn't you agree?"

Yes. Yes he would. Those eyes were... Something else. It felt like he was being drawn into a black hole, except at the end of that journey was a lifetime of candy and pillows rather than having your atoms compressed into an impossibly dense gravitational point. She sat down next to him, and consumed his world. All he wanted to do was hug her closely, to kiss her tender lips. Kurumu slipped her glasses into a breast pocket and smiled at him. Tsukune felt like his heart might stop from just looking at her.

"No petting back there," warned the bus driver. Tsukune leaned away from Kurumu, suddenly feeling quite embarrassed by his behaviour. He'd just about gone in for a kiss without permission! Whatever must Kurumu think of him?

"So," Kurumu said. "Tell me about yourself, Tsukune Aono. What kind of boy are you?"

At which point, time just flew right on by. Tsukune paid no attention to his surroundings. Every now and again he'd get this glimmer of thought to ask about how long the ride would be, but then one look at Kurumu and he'd go under yet again. She was so pretty it was all he could think about. So beautiful that nothing else mattered. So radiant that she outshone the sun. So sexy...

"We have arrived," the driver suddenly said. Already? So soon? Tsukune felt his mouth become dry as Kurumu rose to her feet and patted him on the knee.

"It was a pleasure talking with you," Kurumu said, giving him one last smile before walking off towards the front of the bus. "I hope we meet up again sometime soon. Okay?"

"Okay?" Tsukune weakly called after her. He remained in his seat while she walked forward. His eyes couldn't be removed from the gentle sway of her skirt if you had a team of wild horses attached to his retinal muscles. A cute girl like this was surely once in a lifetime!

Or, rather... As Tsukune was about to learn: Sometimes good things come in threes.

---

Kurumu's face was a carefully controlled mask that shone brightly with her natural - or rather supernatural - prettiness and allure. It helped to smile. A nice smile set people at ease. Seeing someone else smile a sincere smile subconsciously made other people happy. In the end, Succubi are all about making people happy. That's how they control people. They joy you into submission to their every single whim.

Inside though, Kurumu was not happy. She'd analysed the data. Memorised the monstrous form of every single student in the school. She had calculated weaknesses. Used the data gathered by the school to formulate likely weak points of almost every single member of the student body and half the staff. She'd even gone around and paid a special personal visit to every member of the school's security team and brought them to heel.

And then there was Tsukune Aono. A mystery wrapped in an enigma. She couldn't tell anything about him at all. He smelled like a human, his grades were pretty average, his monster type was unlisted. The data was simply... Not there! For a plan like hers a missing variable like that could throw off so many other calculations, and she'd never know what until the time was right.

That's why she'd been staking him out, you see. Watching him and his family trying to get a clue. What kind of monster was he? Surely eating habits would clue her in. No? Any form of unusual activity? Nope!

And that was why her application had to be changed in a hurry to ensure her pickup was the same as his. It was the most logical course of action. Approach him while the rest of his family was around to notice any behavioural changes, they might twig that a succubus was messing with their dear handsome son. Make no mistake too that he was pretty handsome. In fact, so cute that Kurumu had to deliberately restrain herself from falling for him during their conversation on the bus.

But never mind that. She'd been able to charm him easily enough, and he'd been all but swooning over her. The only problem was the bus driver. Otherwise she would have simply smooched that nice, handsome boy there and then, or asked him directly what kind of monster he was. That was all good! The trial run had worked under safe conditions. Now all she had to do was wait, get him alone, then pounce and take what was rightfully hers - the first actual member of her harem!

Then she could move on and properly set up all the other dominos to fall over. Honestly, this one boy had left her so far behind that she couldn't even believe it!

"Oh, I feel so weak..." moaned a girl, but not in the way Kurumu liked a girl to moan and whimper. She peered around a tree and saw... Tsukune rushing towards a girl with pinkish hair. The succubus felt her face turn white, and she ducked behind that tree faster than she'd ever done anything before in her life. "So hungry... Just a nibble of your neck would do..."

"Huh? What do you guhhhh..."

"Moka Akashiya!" Kurumu whimpered. "One of the - No, the strongest vampire families out there! In terms of willpower, strength, intelligence and beauty they are completely unmatchable."

If Tsukune was the blind spot, then Moka was the impenetrable forcefield. She was one of the few known quantities that Kurumu had absolutely no gameplan for! None at all! Sure, she'd worked out a way to make her charm work on girls, but a Akashiya would twig that something was up long before she could pull that trick off.

Though it galled her that she had to do this for such a splendid leggy beauty, Kurumu had resolved to deal with Moka last. At a point where she could overwhelm the vampire by pure dint of genius, cunning, weight of numbers and diversity of available powers. Even an Akashiya would not have been able to handle that!

"S-Sorry, I didn't mean to do that!" Moka gasped. "Oh... Sorry, I know that a vampire's bite can be very pleasurable for a human. Kya! I wasn't supposed to say I was a vampire, was I? Stupid, stupid, stupid!"

And that was the other issue. Vampires can charm people, and their bites had a strongly sexual connotation. Kurumu bit onto her nail. Even with her perfect body and perfect mind, this was a truly great challenge to start her great harem building! The two obstacles that she had intended to take first and last were now standing side by side. What should she do first?

Chapter Text

Kurumu grit her teeth in frustration as she watched her first target chat with her biggest hindrance. This was just ridiculous! The most unlikely possibility of all the numerous variables. What were the chances for these two to run into each other just when she was trying to take out the greatest unknown in this whole situation?

The pink-haired girl smiled at the dark-haired male who was blushing and looking away in embarrassment. Just..... urgh and now she was pulling off the whole cute airhead spiel like it was perfectly normal. If Kurumu didn’t know who this girl was, she may have even fallen for it! What incredible acting skills. Although the Succubus was still annoyed, she couldn’t help but admire this ability to utterly fake harmlessness of someone coming from a family producing nothing but killer machines.

And the Vampire’s beauty was certainly the real deal. Although her curves were not as impressive as Kurumu’s, her skin was pale and beautiful in a different way than her own. Truly, this was a grand prize worth fighting for… but Kurumu knew that right now there was no chance to get her hands on that prize. Even at the best of times, she wouldn’t want to fight the Vampire and right now she would also have to look out for the enigma that was Aono Tsukune.

No, that was certainly not worth risking anything. Maybe if someone else was risking their head....

Kurumu paused in her thoughts, letting that new idea float into the upper spheres of her mind. Yes, that did sound like it could be worth a try. If she did it right, she would kill two birds with one stone. Get a better glimpse at Tsukune’s abilities and move further with her harem plan. If some bullies targeted Tsukune, there were 2 possibilities. Either the Vampire would leave him to swim on his own and discard him if he didn’t prove strong enough. Or she would defend him and claim him as a pet. The latter would be bothersome, but it would still be better than doing nothing.

Right, no sense in burning daylight! Better get going in her search of some shady types that would hopefully put up a fight. She did not want to end up collecting some total weaklings who would just get stomped without her target even needing to use effort after all.

She deserved the very best after all, even if she was eventually going to catch them all.

*Scene Break*

Take a small girl that wasn’t yet in the arms of puberty, put her into an outfit that all but screamed “witch” and then you had a perfect description of Yukari Sendo. Oh, she did wear the uniform, but the big witch hat and some other modifications to it were kind of a huge giveaway. When Kurumu saw the girl, she couldn’t help but wonder what she was thinking? The entire point of this school was to not show off your real nature and try to fake being human as well as possible.

It was almost as bad as when that Vampire had openly stated her race. But at least it made sense given how famous her family was. Anyone with half a brain could find out who she was. This though, it was almost like she was screaming out into the world what she was, something that Kurumu would never do.

And the girl was currently in obvious trouble.

“Now now, what do we have here? A little witch without her gingerbread house?” There was a rather mean laugh from one of four males that were surrounding the girl. Yukari turned towards him, a small wand with a heart shaped tip pointed at the male like a weapon. Which to be honest, it was, if only in the hands of a genuine magic user.

“Hmmm… I am kind of hungry, maybe we should take a bite before someone else gets this one?” Once again Yukari swirled around and quickly looked at another of them who was licking his lips in a rather creepy manner. The males kept making such comments for now while the girl was clearly growing more and more panicked. It was just a question of time until their idle suggestions turned into something more after all.

Kurumu observed this with some distaste colouring her feelings while hiding behind a bush. Witches were unpopular among monsterkind. Mostly because they were a little too close to humans in looks and nature for many people's liking. That still didn’t excuse this sort of activity. It was one thing to dislike someone, another entirely to go out and think about eating them!

Right, Kurumu thought about what she could do under these circumstances. Going in and taking them out was possible. But it was also risky given it was 4 against 2, assuming the little witch could even do anything useful in a fight. Much better to use one of the oldest and most successful tactics known to monster- and mankind alike.

Grabbing a stick from the ground below and with a quick movement, shattered the short branch. The sound of cracking wood echoed across the area and the boys immediately turned towards her direction. The one that she assumed to be the leader of their little group made a waving motion and two of them moved away, one towards the left and one to the right of her. The one who had waved moved straight towards her while the fourth remained close to Yukari.

Better thinking than she had expected of some random bullies. But such a simple plan was nothing to a genius like her! Moving slowly, she moved towards her left so that her path would soon cross with one of these boys.

Quietly, she watched the male and immediately identified him using her perfect memory. Tahara Yasujiro, a umbrella type youkai known commonly as Karakasa. Nothing impressive as far as these things went, and rather weak against cutting weapons like her claws. Sneaking up on the boy from behind, she let her fingernails grow to incredible size until they were sharper than the best knives. In a quick motion, she put one finger on the boy’s throat, just above his adam's apple.

“Oh my, is the bad boy searching for something to play with?” The male froze as Kurumu giggled quietly, one finger playfully tousling his dark hair. Pressing her chest against his back, she whispered into his ear. “But it looks like you are the one who will be the plaything.” Immediately Kurumu felt Yasujiro’s breath hitching in excitement and without letting go of his throat she turned the young man around. When they were looking at each other, she smiled and said. “Now just take a good look into my eyes and we will have so much fun.”

It was very easy to get this one under her thumb. He was so deliciously helpless, it almost made her feel guilty.

Almost.

Kurumu moved on from there, telling her toy to stay quiet while doing so. It was fortunate that the off-path area of Yokai Academy was rather forest-like and wild. Otherwise her little trick would have been discovered by the rest of them immediately.

Quickly, she moved through the underbrush, her new slave following her with hearts in his eyes.

“You move over there and distract your boss. Tell him you saw something in the other direction while I deal with your little friend.” She smirked at the red faced boy who looked at her like he had never seen a girl before. It was always so fun to see her charm really doing its work.

The other boy was an anxious looking one, always checking every corner. Getting a quick look at his face, she identified him as Oba Saneatsu, a Tofu Kozo of all things. Famous for being one of the weakest known Youkai and well known for the unnatural love for the food in their name. They were only really used as messengers and the lowest of foot soldiers, easily beaten by any Youkai of note, if still stronger than normal humans.

That.. was almost insulting to be honest. Kinda pitiful as far as potential opponents go.

Shrugging and releasing her wings, she quietly flew into the air while making sure to not be seen by the male. Then she giggled quietly and crashed right into the boy from above. There was a short sound of confused shock as she hit the student and toppled him over. Landing directly above him, she looked down with a wide grin. “Searching for someone?”

The boy looked at her face, then further down in the direction of her skirt which had been placed tactically to grant a view of heaven. The poor guy’s face turned a deep shade of red at the view. Kurumu giggled louder this time and kneeled down while pushing her knees up so the boy’s view was never blocked.

“Oh how cute, I think I’m gonna gobble you right up.”

Saneatsu faced doom, but he honestly didn’t mind at that moment. Or any moment that followed from then on to be honest. So long as he was in her presence, he probably wouldn't mind even if he was walking on hot coals.

*Scene Break*

“You said that you saw something here?” He asked with a frown on his face. The leader of this small group of delinquents looked at Tahara with suspicion. The guy had probably just seen a squirrel or something now that he thought about it. Maybe he should have just let this be, then they could be eating the brat right now.

His hair was a rather distinct red, not dyed but clear and natural and his eyes were blue and furious. There was a reason he could boss around the other three and it wasn’t because he had won a round of jan-ken-pon. His name was Ban Shunmyo, Shun to his friends and family, though he had none here in Yokai academy so far. None of the other three had proven to be worth calling friends yet.

There was a sound in the shrubbery next to him and he immediately froze before turning in that direction. “You go in there, I will make sure that nothing comes in from behind you.” Brooking no argument even at the somewhat scared look the other boy was giving him, he pointed at the bush. Tahara sighed and moved into the bush while Shun kept track of the surroundings.

Quiet.

No sound except the breeze whistling was heard as the other boy moved into the brush. Time went by, first a few seconds, then a minute and finally the redhead was starting to get a tad worried.

“Oy Tahara, did you find anything?”

There was no answer and the young man felt a shiver run down his back as something flickered at the edge of his vision. Twisting to get a view, he saw nothing but trees and bushes.

Then came the laughter.

It was a loud and full sound not unlike chiming bells, something he would have called pretty and attractive any other time. But as it resounded within the darkness between the trees, Shun felt only trepidation. The laughter coming from a clearly female voice brought about certain images from a visit to a movie theater he had made with his family years ago. They had accidentally stepped into a horror movie involving a terrifying girl with long dark hair and eyes that made his younger self freeze in fear.

No wait, that was stupid! He was a monster not some stupid little human. It was his job to scare others, not to be frightened by things in the dark.

Slowly he walked through the bushes and tried to find the origin of the voice.

“AHhhhh!” The scream almost made him leap into the air right there. Had they gotten someone else? Was it just one girl, could it be more than that?

He gulped and took a step back.

No! He couldn’t let this stop him…

Closing his eyes, he let go of his disguise and showed his true form. A Eritategoromo, appearing in the form of a buddhist high priest’s kimono and imbued with great powers. He called out into the darkness.

“If you think this scares me, then you are wrong! Come on and fight me right now or begone!”

There was no sound the next moment and also not the one that followed. Silence was all that answered his words.

Then a sweet voice whispered into his ear.

“You called?”

Whipping around, he let his cloth body expand and then twist it into a drill like form. “Spiral Weave.” His form extended like a long twisted drill and hit a tree, boring a deep hole into it. He blinked in confusion at having missed and twisted his form back near-immediately.

“Kukuku.. not bad. But that move has a big weakness. You gotta use your whole body for it, right?” That was right of course. If he trained long enough, he should be able to use the equivalent of an arm or leg, but right now it took a lot of effort. It was still frustrating to have it thrown into his face like that.

Then he saw the one who was taunting him. A girl with blue hair floating above him thanks to a pair of wings, her eyes shining red in the darkness between the trees. Growling, he brought his arms into a specific position. “Feather Weave.” He called out and immediately flew up in the air as his two arms formed into something akin to wings.

“Oh, that is interesting, but can you fight like that?” Now that he got a closer look, he could see that this was a very pretty girl. The sort he would normally try to hit on without hesitation, but now he was too angry to even think of something like that.

Without hesitation, he released a firm jab of cloth into the winged woman’s direction. In simple terms, he was headbutting her, only his head could extend quite a bit.

The girl actually looked surprised as he suddenly bridged the gap with his attack. Bringing her hands up, her nails grew into long and deadly claws. He felt them cutting into him even as he crashed right into the girl’s chest. There was an sound like an “Ufff” as the female was pushed back and started quickly falling.

Not wanting to let her catch her breath, he immediately followed up by twisting into a shape not unlike a hammer. Following her, he prepared to crash right into the girl.

Only for her to smirk and be grabbed by someone rushing right past her. Shun blinked, then crashed into the underbrush, unable to stop his descent quick enough. Trying to return to a combat ready form, he felt his body ripping at multiple parts from cuts of his fall and the girl’s claws. That would hurt later.

He turned back to see his own minion standing by the side of the girl. Tahara in his umbrella form had used a quick motion to catch the girl right out of the air and away from his attack. To think he would dare to betray him.

“Not bad for a warmup, but you will have to train a bit more if you want to give me a real fight. If I wasn’t playing around, you would have gotten hurt.” Her voice was taunting yet seductive in its tone and immediately made him feel rather uncomfortable.

“Still, you did show me some interesting things, so I guess it is fine to also show you something nice.” Shun tensed, readying himself for whatever attack came next. He wasn’t in any good state for further fighting, but he wouldn’t go out without getting a real hit in!

The demon in front of him only giggled, her hands playing with the bottom of her polo shirt. What was she planning? He watched carefully as she grasped hold of her clothes.

Then flipped them up in a single quick motion to reveal a full pair of gigantic breasts. Shun had never seen a real life pair of breasts on a girl his age. And these things were huge and looked incredibly soft and squeezable. It absolutely ruined his entire thought process and just for a moment he forgot why exactly he was angry at the girl connected to these huge tits again.

Then he blinked, which was kind of strange since he was made of cloth, and looked up at the girl. Only to peer into the wonderful face of a goddess of beauty and perfection. Immediately his short run into happy land restarted as he felt totally happy just looking at this sensual beauty. These boobs, these lips, that everything! It made him question why he ever thought it was a good idea to even try challenging her.

“Now then, do you still feel like fighting? Or would you rather let me do the thinking from now on?”

Oh, why would she even ask? He felt nothing but happiness at the thought of serving this girl. When he voiced his thoughts, she only smiled sweetly, which made the small part of his brain which was voicing concern over his sudden change in opinion go bye bye for a bit.

It would stay that way in the future.

*Scene Break*

Yukari Sendo was genuinely considering whether to make a run for it and risk a tousle with the crazy guy in front of her. Sure, he had made rather clear what he planned to do with her and it wasn’t a nice chat or anything. Still, maybe losing a ear or something like that in the ensuing struggle would still be preferable to being eaten for sure.

But Yukari was young and naive even though she was a genius. She just didn’t have the nerve to just start such a high stakes duel without hyping herself up for quite a while. Which may have had bad consequences if not for what happened next.

“Airdrop!”

Yamaji Eizo blinked and looked up as something hit his face from above. There was a sound of something cracking and he blinked as a big rock bounced on the ground after hitting his head. He twitched, then fell over like dead weight.

Yukari watched that happen before her jaw dropped in surprise.

A moment later her savior landed on the ground with a smile. She was a girl with blue hair in a polo shirt, wearing a somewhat modified school uniform. And her chest was huge, bigger than her mother’s by quite a few sizes even!

Kurumu meanwhile was all but fistbumping herself for this great entrance. Everything had gone as planned, well that one guy had managed to surprise her with some of his tricks. But hey, it had still worked out and now she had a few minions and hopefully a thankful new companion. Sure, she wasn’t going to have any chance to use her charm but...

“Thank you!” And then Kurumu found herself hugged rather firmly by a very skinship happy witch. The Succubus stopped in place at the sudden show of closeness, then slowly returned the hug and patted the girl on her back. “There there, everything is fine now. I showed these guys who is the boss and now they will do anything I tell them. Won’t you?”

She turned to the rather tattered looking priest’s kimono Yokai who was just stepping out of the bushes not too far from her. Yukari blinked and hid behind the bigger girl, only letting her head poke out.

The former bully just nodded his head before answering with. “Yes of course mistress Kurono.”

The Succubus smirked. “Ooh, I never get tired of that.”

Yukari was meanwhile looking at her in dumbfounded wonder before blinking and looking down at the ground for a moment. Finally she looked up, a strange look on her face. Then Kurumu scrunched her nose as a familiar smell flew into her nose. It was almost like…

“You are so awesome! Please let me be your girlfriend!” Kurumu once again froze at that before being overwhelmed by the much smaller girl’s hug. The witch was now pressing her face into the blue-haired girl’s breasts and all but motorboating them. She hadn’t even done that with a boy before!

And that was what she had smelled. Desire, of the sexual kind. Succubi had good noses what that sort of thing concerned. They were fundamentally creatures of love, empowered and born from it. Though Kurumu didn’t quite buy that literally. She hadn’t felt better no matter how many boys or girls she caught in her old school and made worship her form.

Still that small head nestled between her chest, it would be so easy to tilt her head up a little and just charm her and that would be.. that would… ehhh actually that would be kind of creepy with a little girl like that, wouldn’t it?

Kurumu may be a pervert, but she still had standards!

Yukari, meanwhile, did not have any such problems. If anything, she was already mentally planning out the wedding and honeymoon. It could be said that of the two, she was the one who worked faster when it came to matters of love! Which was rather ironic considering who of them was the Succubus.

“Haha… well how about we just start off as friends and see how things go from there?” Kurumu asked, feeling a little awkward in spite of herself. It shouldn’t be that hard to get a love confession! She was a demon of lust and perversion for lord’s sake. Sure, the first time she got such a heartfelt confession without any use of her charm was from a girl years her junior and… okay that just got depressing. Moving on and not thinking of that!

“Yeah sure!” Came Yukari’s answer as Kurumu tried a smile in answer while ignoring the way that the younger girl was manhandling her chest. She was just a little girl, even if she had a bit of lust, she probably didn’t even know what she was doing. “Great, then let us just get going. If we are quick, we can still get there before the entrance ceremony is over.”

She sighed when the girl finally let go of her chest. Sure, she was proud of her big breasts, but that didn’t mean she wanted them to be used as toys! At least not unless she could also have some fun with the other party. The three boys that had become her newest servants went to follow their group, picking up the unconscious one at her command. She would have to charm him later too. A short glance and… yeah he was a Jikininki, stupid cannibalistic semi-undead monsters that were perpetually hungry for everything and everyone.

Eh, she could always have him eat the food she couldn’t eat for fear of gaining weight. He should gain a better personality once he got properly reeducated by her.

Chapter Text

The perks of a harem were immediate and obvious. In the middle of this wood, Kurumu had instructed the Jikininki to get on his hands and knees while she used him as a seat. This was a fate she would reserve only for the worst of yokai, the bullies and those who had little regard for others. True enough they would enjoy the feeling of her posterior resting upon the small of their back, but it would be an abject lesson for them. Their rightful place was beneath her.

"Uwah! You're so cool, Miss Kurono!" Yukari chirped. The young witch was sitting next to her, a little closely for the liking of this succubus. That strong desire was giving her a bit of a sugar rush like high. "You've completely tamed these bullies right away!"

"Well, I could hardly allow them to continue picking on you..." Kurumu absently said. She uncrossed her legs, then demurely switched which leg was crossed over which. "Tahara, if you wouldn't mind shifting a little to the left? The sun is still in my eyes."

"Yes Mistress!" The umbrella yokai hopped a little across. She beamed at him and gave him a thumbs up, which would quite probably make his day.

While this was pleasant, Kurumu didn't really have all day to lounge around with her first proper acquisitions. Not to mention the complication this little witch presented! This desire was pretty strong, heady stuff, but she could not bring herself to use her charm to get her under complete control. Look at her! She's so small, it wouldn't be right at all!

"Um... Is something the matter?" Yukari suddenly asked. "I know we've just met, but you seem troubled by something, Miss Kurono. Is it something I can help with?"

"Ah, well... It's nothing much," Kurumu said. She flicked her hair, and then had an interesting idea. "Maybe... You can help. You see, there's this wicked vampire, who I caught feeding off of a poor innocent boy, just off the bus." All true. Like all of the finest lies, there was a strong element of truth to build upon. "I wanted to help save him, but I knew right away, the sheer difference in strength would be far too much."

She extended her fingernails and stared at them wearily. "A scary strong vampire like that is too much for a delicate flower like me to handle. And she's almost as pretty as I am!"

"No! That's impossible! Nobody could be as pretty as you!" And other assorted sentiments along those kinds of line were all blurted out at once from each of Kurumu's harem slaves, and also Yukari. Curiously she seemed the most enthusiastic about this. That was... Worrying.

"I'll deal with her!" Yukari defiantly declared. "I'll stop that scary vampire myself!"

"No, Yukari! Don't fight her!" Kurumu warned. "I think it would be much more useful if you were to... Study them for me. Watch them from afar. Tell me what they get up to. Pretend that you have fallen under her wicked influence as well. That way, we can at least find out what she's really up to, and if it's naughty... We spank her."

Yukari held up her fists and gave a curt, cute nod of total understanding. Alright... Not what she had originally had in mind, but it was a start. The ability to think on one's feet and adjust plans to fit the situation, that was the mark of a true genius! Off the witch skipped, and as an added bonus Kurumu could now proceed with plans that were rather less suitable for the eyes and ears of a girl her age.

"Alright then," Kurmu clapped. All four boys - save the one she was sitting on, dropped to their knees in abject adoration. "Which of you jerks already has a girlfriend?"

=====

It was the start of a new year, and she was absolutely ready to move up the school totem pole. That was the benefit of being a second year, after all: You already have the lay of the land. Sure, her boyfriend might not be the toughest guy going, but it was kinda better that way anyway.

Her name was Hua Mizuchi. She was a cute girl with a pretty face and a bob style haircut. She'd always had a bit of a tendency towards troublemaking, which only made sense for a zashiki-warashi like her. Still, she had aspirations for more, and the first step to manage that was to get a cute, hunky strong boyfriend that she could use as arm candy.

Not the strongest, keep in mind. But one of the strongest? Perfect. That let her elevate her position considerably without having to worry too much about some idiot thinking they could get one over on her b.f. by kidnapping her. Who needs that kind of hassle? Not her, that's for -

"Knock knock!"

Hua was snapped out of her thought process by the sight of a pretty glasses wearing chick standing by her dorm room doorway. Bright blue hair, tits that were, bluntly, unfair.

"Something I can help you with?" Hua haughtily asked. The big titted bluebird flitted into the room nervously, like a mouse. Nervously looking around at everything.

"I'm looking for a place to hide!" the girl said. "Please help me! Won't you help me, please?"

"You're a first year right?" Hua asked. The girl nodded. Gotcha! What super luck this was! "Under my bed! I'll be your guardian angel, I'll bring you all the good luck you need."

She didn't expect to be pulled into a sudden hug like this out of nowhere. "Thank you! Thank you so much!" she cutely whimpered into Hua's ear. Oof. Weird. The feeling of those tits up against hers like that felt weirdly good for a half second there. The girl dove for the bed, uncaring that her short frilly skirt flipped up. You could see everything. It wasn't that Hua was a lesbian or anything, but damn that girl had some appeal about her and no mistake!

Another thing that Hua didn't expect was her boyfriend rushing into the room all of a sudden. Shun looked unusually flustered and red faced, like he'd just been chasing someone. Oh no, don't tell her... this was too delicious!

"Yo, babydoll! You seen a sneaky blue haired bitch run by?" he asked, and then gestured at a stain down the front of his uniform. "Spilled her drink down my front! Gotta teach her a lesson in respect!"

So that was why she was running like that? Sensible! Anyone should run from Ban Shunmyo if he was angry at them. How unlucky for little miss appeal, but also lucky for Hua. "Sorry, she just bolted by looking scared out of her wits. If I'd known you were the one chasing her..."

"... Feh!" he grunted, then turned around and continued on his way. Hua waited a few moments. She could feel a truly wicked grin forming on her face. Whoever this new girl was, she was now totally and completely under Hua's thumb. A brand new minion. She would calm down Shun, clean his uniform, maybe fool around a little, and this big titted cutie would be at Hua's beck and call for the rest of the year. How exciting!

Hua closed the door and said "You can come out now! He's gone."

The girl popped her head out from underneath the bed. How adorable! How coy and charming she was. If she were a nicer person, she might actually feel protective of this moeblob that had stumbled into her lap. "Is he really gone?" she asked, batting her eyes innocently upwards.

"Yes he is!" Hue answered. "Ah, you upset Shun, did you? That's very bad luck! What's your name, little freshman?"

"K-Kurumu!" she sobbed, staining her pretty little face with tears. "Am I really in a lot of trouble?"

"Well, not really no," Hua said. "So long as you do as I tell you, there shouldn't be a problem. I'll be able to calm him down for you as a... favour."

Kurumu was suddenly out from under the bed and hugging Hua very, very tightly, pressing her face directly into her soft, very soft breasts. "Thank you!" Kurumu enthusiastically cheered, jumping up and down in place. "Thank you, thank you so much! I will be eternally grateful to you!"

"N-No problem!" Hua gasped, pushing herself away from those dangerous weapons. "Listen, if I'm going to help you out then we need to get to know each other a little better, right? Why don't you hide in here just now? I have to try to finish off remedial homework - "

"Homework?" Kurumu interrupted. "I can do that for you! Oh... Actually, maybe it would be better if I showed you how to do it?"

Showed her...? A freshman wanting to do a second year's remedial homework? Must be some kind of bookworm. It certainly fit the glasses. Hua grinned at her luck. If she proved useful in that area, that alone would make up for any difficulty she faced. It would help keep her grades up, which would be very helpful in getting her a decent societal position for being such a weak and lame monster.

"Here it is!" Hua declared, shoving it right in Kurumu's pretty face. "You think you can do this?"

She scanned down the sheet, tilted her head and then nodded. "Done. Already worked it out."

"Yeah right, there's no way you could have solved -"

"Answer one: 3X+Y. Answer two: 37. Answer three: pi squared. Answer four..."

Hua interrupted her by sticking out her hand. What? She'd just solved these questions by looking at them? "You really are a bookworm, ain'tcha?"

To which Kurumu gave a truly beautiful smile. Hua was pretty sure she was straight, but... Wow, this girl was really charming in her innocence, wasn't she?

"I try," Kurumu fidgeted. "But, only because I know I'm not cute or pretty or strong or anything. Um... I could show you how to solve these problems if you want? I know a few tricks to make it easier for you... I mean, if I just gave you the answers then it would become obvious when it came time for the end of year exams, right?"

Right... Yeah, of course. There was a kind of sense to that, wasn't there? A free tutor to help her out. That didn't sound so bad, no that was rather lucky. Before she knew it the two of them were lying on her bed, side by side, with the homework in front of them.

"It's all really simple," Kurumu said, and that was the last thing Hua understood coming from her lips for a good minute and a half. She didn't interrupt though. There was something oddly melodic about her voice. Hua caught herself staring at Kurumu's lips as she talked and talked about what sounded like total nonsense. "The main reason for integration is to find the area under the curve. So, you've got to pay very careful attention to the curves, work out their formula and then you'll be able to feel it out. Does that make sense?"

Hua's mouth was dry. Incredibly dry, and she had no idea why at all. Her brain felt numb after that barrage of smarts.

"Um... Sorry, did I get lost in the explanation?" Kurumu asked. Hua nodded. "Ah... Sorry, that probably wasn't all too helpful was it? I'll get you some water, and then we'll start again."

To switch perspectives for a moment, Kurumu was internally cursing herself. She really had got herself lost in that chance to show off her intelligence, and taken it too far. Still, things were coming along quite nicely. Just a little more of a push, and Hua would be all -

All of a sudden Kurumu tripped over. Letting out an almighty "kya!" she landed, catching herself deftly on the ground. Stupid! Careless! She let herself get flustered! Hua poked her head out from over the bed. "Are you alright?"

"I'm fine!" Kurumu answered. She picked herself up and dusted herself off. "I'm perfectly okay!"

But now, to switch perspectives back, Hua was frowning at something she'd just noticed. When Kurumu had stood up, her eyeline had settled nicely on Kurumu's swishing skirt. She hadn't thought anything of it, merely staring at another girl with a killer pair of legs while trying to figure out how to get that kind of figure. That was her justification. Except, just now, when Kurumu had tripped, she had let something slip out that should have stayed hidden away.

"Is that a succubus tail?" Hua asked suspiciously. Kurumu jumped and moved to hide it away. "It was, wasn't it? Are you... A succubus or something?"

"So what if I am?" Kurumu shyly asked. "You're safe, right? I'm just too shy to charm people... And girls are immune to charm anyway, s-so even if I had the guts I wouldn't be able to -"

"Really?" Hua asked. "A prudish succubus who just ran away from my boyfriend? Without trying to charm him so he wouldn't be scary anymore? Now I've seen everything."

"Uwah! Boys are even scarier when they're horny!"

That was true enough. But Hua wasn't convinced. "I've been feeling funny ever since you came in here. Pressing your boobs against me, flashing me your ass, that close contact on my bed... You've somehow worked out a way to charm chicks, haven't you? That wasn't some ordinary trip just now! That was my 'good luck' trying to warn me about your attempt to brainwash me!"

"Luck?" Kurumu asked. There was a shade over her eyes, cast by her bangs. "What is luck anyway? Can you measure it? Can you control it?" She stood up and whipped off her glasses, tucking them into her uniform's breast pocket. "No, you can't! Because people do not control luck, but rather the opposite! People are slaves to their so called 'luck'!"

She stepped back a few paces, away from Hua, which was for the best as now Hua was being very careful where she was looking. A succubus charms through the eyes, so don't watch the eyes. Instead, Hua reached around for her bat. As the girlfriend to a tough guy it always paid to have a weapon nearby, and she might not be the toughest monster around...

Yes, that was it. Keep her eyes closed and demonstrate her luck! She rose from the bed, bat in hand, ready to swing around wildly! "Me? A slave to my luck?" she asked, suddenly tripping over nothing. She felt a woosh of... Something passing by where her head was. "My luck and I are partners!"

She jabbed the edge of the bat and hit something definitively humanoid. It made a grunting noise that Hua enjoyed quite a bit. "You see?" she boasted. "I was born from luck in the first place! Calling me luck's slave only goes to show how twisted a succubus thought process can get!"

A creaky floorboard gave away Kurumu's position. Hua was enjoying this! Shun hadn't chosen to date a weakling, she was a lot more than a pretty face and a serene smile. She whipped around and cut loose with a wild swing that would put the succubus out of commission for good!

"A girl like you has no place to criticise my view of relationships," Kurumu said... From behind Hua! The bat hit something distinctly metal, and then she was shoved forward, finding herself being hit in the face by water, spewing out of something. Without thinking Hua opened her eyes to see what the hell she'd just whacked, and found it to be the tap in her kitchen sink.

Then, she was spun around and found herself staring at a soaked through white shirt. Kurumu's jumper discarded to the side of the room. They were... Spectacular. Perfect. For the first time in her life, Hua thought that she might actually be a lesbian.

"How are you doing this?" she asked.

Kurumu simply smiled and tilted her head up. "Small repeated doses of charm, combined with carefully calibrated flirtatious behaviour," Kurumu answered. "Your level of attraction to me started out quite low, but built up over time, a little bit more every time I used it."

Her eyes flashed a rainbow of colours, and Hua felt herself completely relax. She made to speak, but Kurumu put a finger to her lips.

"Shhh..." Kurumu whispered. "Relax, my dear. With one simple kiss, I will be a better mistress than luck ever was."

Holding her close, Kurumu leaned in and stole the kiss without any further resistance. Hua sighed into it. She felt more at peace and more content than she could remember in years. Well, except for the fact that she was just, unbelievably horny too.

"Mi-Mistress..." Hua asked. She flicked her eyes over towards the bed. "Can we... I'd like to, if it's alright with you..."

"Sorry. I have other matters to deal with. " Kurumu slipped away from her newest acquisition and strutted confidently off towards the room's telephone. Hua was thoroughly entranced by the movement, everything about it. She knew deep down it was caused by the charm and yet it didn't matter in the least. Those legs, those hips, the gentle swish of that skirt, the way she leaned over ever so slightly and continued rolling her hips even though she was standing still while talking on the phone.

"Hi, can you send someone from maintenance up here right away?" Kurumu asked. "Okay, thanks! We'll leave the door open, so just come right on in."

The sexy smart succubus hung up the phone then returned her attention to Hua, blowing her a kiss. Lucky! Then she began to stride over to her with her super hot chest thrust out, the damp cloth still translucent and see through. Super lucky! Then, on reaching her, Kurumu reached her hand behind Hua's head and pulled her into a deep steamy kiss. Ultra super hardcore lucky jackpot! Hua pushed into the kiss as much as she dared, testing out how much her mistress wanted. It turned out she was almost as ravenous as Hua herself. Sure, she felt maybe a little bit drained as the kiss went on but that only made sense: Kurumu was a succubus and they did feed off adoration. And oh but Hua had so much adoration to share!

"Hi is this - Woah!"

The kiss ended and Hua shot daggers at the plumber standing in the doorway, staring in completely gobsmacked at the sight of two girls making out like the world was ending tomorrow. Unlucky!

"Uh... I can come back if you're busy?" he squeaked, trying very hard not to look at them.

"Oh no, don't mind us!" Kurumu insisted with a naughty twinkle in her eye. "Get to work, treat us like furniture." she tilted her head and gave Hua an extremely obvious open mouthed kiss. "Treat us like furniture. You don't mind, do you Hua?"

"Nnnnoooo..." Hua answered. It was about as much as she could intelligently state given the heaving breasts pressed up against her own. If Kurumu had ordered her to give her a naked oily lapdance in front of the entire school body then Hua would've definitely gone along with it!

"W-Well, I mean... Okay, if you're sure," the plumber mumbled. He picked up his bag, closed the door and stepped past the girls towards the sink. "Good thing you called right away, this could've made a hell of a mess."

Whatever he was doing over there Hua didn't give a damn. Kurumu had returned her attention to their makeout session with an absolute vengeance. The succubus dragged her to the bed, toppling them over so that Kurumu was laying on top while Hua was down below.

Within this new position Kurumu's perfect right leg coiled around Hua's, while her right hand groped firmly behind Hua's ankle. "Reach under my skirt," Kurumu whispered, and Hua's hands shot there so fast she was worried she might break the sound barrier.

Her thighs! Oh, divinity! Sweet perfection lay in every inch of her body, but right at that moment the creamy skin beneath that skirt was all Hua could think about. It didn't seem possible that any other part of her could equal this, yet at the back of her mind she knew intellectually that it was true. Kurumu's body was just as brimming with sex appeal from head to toe. The fact that she was flipping up her mistress' short skirt in such a way that lay within the plumber's peripheral vision was completely and totally lost on her.

"Girls these days..." the plumber groused, but still snuck a peek. Kurumu scowled. Only a peek? Time to play hardball!

She broke off the kiss and reversed positions so that she was mounting Hua reverse cowgirl style. Grabbing the wrists of her new harem acquisition she guided them up her sides until they were resting on her breasts, then let them go and put her hands above her own head, letting Hua's newfound lesbian lust guide her actions while grinding her hips suggestively. Combine this with her damp see through shirt and her spectacular tits, and - voila.

"Hot damn!" the plumber whispered, then adjusted his working position so that he could hide his erection. "No, no. Not staring at students. Going to get me in huge trouble, those brats are obviously teasing me to get a rise out of me... I'll report them later on for breaking this tap, let's see if they find that funny!"

Now Kurumu's pride as a succubus was really getting annoyed! Alright then. He asked for this!

"I want to feel lucky," Kurumu huskily said. "Please Hua, use your old mistress to satisfy your new one."

Almost as soon as she said it a burst of water hit the plumber right in the face out of nowhere. Due to a combination of the shock and the water pressure, he stumbled backwards, slipped on a wet patch and landed face first right in Kurumu's breasts. Where he stayed for a good second or two, in no small part because of Hua's hands holding him in place.

"Good girl," Kurumu snickered. She pulled Hua's hands away, then lifted the still dazed man's face to look her directly in the eyes. "Now. I'm not just a student, am I?"

"N-no, mistress..." the plumber answered, totally lovestruck.

"Good boy. Now fix that tap, and when you're done I'll be sure to make the charm permanent. I have such plans for you..." Then she returned her attention to the girl beneath her. "In the meantime, I rather think it's about time your boyfriend got lucky, don't you?"

"If that is what you desire mistress," Hua answered immediately. To which Kurumu tittered, jumped to her feet and strode over to the door - retrieving her jumper along the way. She knocked on it and then Shun opened it wide, slipping inside with a goofy grin on his face as he stared at Kurumu's still see-through blouse. Though that smile turned into a slightly disappointed sigh from both boyfriend and girlfriend when she put her jumper back on.

"Happy minions are good minions," Kurumu mused, then blew all three of them a little kiss. "And there's nothing that makes a minion happier than... getting lucky."

Chapter Text

Meanwhile, a certain pair were completely oblivious to Kurumu’s nefarious plans to take over Yokai Academy and turn the students into her harem. They were contentedly going about their business, meeting cute and forming the basis of a long and lasting relationship.

 

Nom!

 

Well, one of them was a vampire and one of them was a human. Something like this was inevitable in the end. Still, Tsukune did rather wish it didn't have to be. Moka was so nice and so pretty. It was kind of incredible, he had always been kind of average and today he had met two incredibly attractive girls who treated him kindly. First that blue-haired student with the rather.. impressive chest and now this beautiful vampire.

 

Though he was still kind of confused because of the whole ‘school for Yokai’ thing. Nevermind the fact that the teacher had cheerfully said that any human stumbling in here would experience ’death or something like that’ .

 

That was said with too casual and cheerful a face and tone! Far too casual! Far too cheerful! What kind of world had he stumbled into?!

 

"Mmm... You know, you're my first Tsukune," sighed the beautiful vampire in front of him. Paradise. This was clearly a hidden paradise.

 

Well, except for the death stare every single male in the area was giving him. Bearing in mind that every single male around him was a monster in disguise, and suddenly an already bad situation was made a hundred thousand times worse.

 

While Tsukune’s attention was split between the girl clinging to him and the dangerous fellows glaring at him, someone else was observing him from a distance. Well not him specifically, but rather Moka Akashiya and the boy she had snatched and enthralled through her charms. Yukari was hiding behind a corner in the hallway and peaking at these two. The pink-haired vampire was certainly deserving of the descriptor ‘beautiful’ but in the witch’s most certainly impartial opinion, Kurumu was far more attractive.

 

From her position in the bushes watching the 'lovey dovey' couple, Yukari's eyes were no less full of malice and hate than any of the boys looking at them. The only difference was her target: Moka, the sneaky vampire sneakily planning to sneak together a harem! How sneaky!

 

She'd already ensnared her very first victim. That hapless, average looking boy. Ooh! How devious! How dangerous! Start with the low hanging fruit, turn him into her slave and then gradually extend her reach across the school! Mistress Kurumu was quite correct. Moka had to be stopped! Nobody should be allowed to have a school-wide harem!

 

Elsewhere, Kurumu sneezed, which rudely interrupted her planning on which club to infiltrate and take over.

 

"Say... Let's go somewhere a bit more private," Tsukune suggested. Oh no! He was succumbing to her wiles even more!

 

"Let's go into that forest!" Moka suggested. Oh no! This was all out of a fairy tale! Don't be tempted by the house of sweets taking the form of a pretty vampire, she'll drain him dry and make his enslavement truly permanent!

 

"You mean... The forest which seems to repel the very light above us, with bats hanging from every second tree branch - each of which is devoid of leaves and has more points and jagged edges than there are trees within the forest - blinking eyes in the shadows and, every half minute on the dot, the sound of a ravenous hungry beast echoes out like a dire warning?"

 

Wow, Yukari hadn’t seen that place yet, it sounded absolutely awesome. Damn, this would only increase the chances that she would further seduce this poor fool. There was no way anyone could resist the atmosphere that would build up in a place like that!

 

"Yes," Moka sighed. "Isn't it beautiful?"

 

"Yeah..." Tsukune sighed, looking at Moka and not the picturesque scene trying to entice him to his doom. "Come on, let's go!"

 

Right! Well, Yukari could hardly have this! Keeping a wide berth and making sure she was well out of sight, the young witch circled around them and rushed on inside the forest. Hrmph! She might not be able to do much, but she could at least rescue that gormless idiot! No matter what happened she'd make sure to undo this vampire's evil. No matter -

 

"Wow, it's really pretty in here!" Yukari sighed, spinning around and taking it all in. No, no! Focus! She shook her head and then ran off through the trees, until suddenly -

 

“Heh, what is a pretty face like you doing here?” Said a scummy sounding voice, a tone to it that immediately made Yukari flinch. The short witch ducked a little and saw a group of students surrounding the pink-haired vampire and her male thrall. The biggest of the bunch, whom she assumed was the leader, was leaning over Moka and giving her a dirty look.

 

“Now why don’t you spend some quality time with us instead of this loser?” He asked, licking his lips in a manner that made Yukari feel sick. Even if she was young, she still understood the intent here. The vampire for her part was looking unexpectedly.. scared and hesitant. Was this some kind of fake play to make these guys lower their guard? From what Kurumu had said, she was some kind of super dangerous monster..

 

Tsukune, good hearted fool that he was tried to interpose himself between Moka and the student. “Hey, don’t you see that she is bothered by this?!” The unfortunate human tried to puff himself up to appear more threatening, something that may have worked if it was only one of these guys.

 

As is the leader of this group gave an annoyed growl and pushed the dark-haired boy away. A moment later the male hit a tree with a thud and.. ohhh he was bleeding and that head injury looked like it hurt. Whatever monster this guy was, it seemed like he wasn’t one of the physically durable sort.

 

"Tsukune!" Moka yelled. Oh, that was good sympathy! bravo, it was almost believable. She rushed to the boy's side, but then one of the other monsters grabbed her wrist. Hrm. On the one hand Yukari was kind of glad to see her get her comeuppance. On the other, bullies like that bugged her too much for her to root for them.

 

“Now now, no need to start screaming- yet that is.” The scummy looking leader said, his eyes wandering over the kneeling vampire’s body like she were a piece of meat. “Say what, if you play along with us, we won’t hurt your little friend.. too much.” He laughed, walking up to the pinkette and grabbing her by the scruff off the neck. “What do you say?”

 

Before Yukari could make up her mind on what to do, Tsukune reached out his hand, and his little finger just so happened to snag on a rosario around Moka's neck. It pulled away-

 

And then it was like something out of a magical girl anime. In an instant Moka's hair turned a bright and dazzling silver. Her cute face grew harder, yet still radiantly pretty. Beyond that it was as if her entire presence had shifted. No longer cute, no longer the innocent naive waif. This was a powerful, mighty vampire.

 

The newly changed high-class monster took a long breath, rising from her kneeling position and letting her hands go through her long hair. Then Moka opened her eyes, which had red like blood and slitted pupils like a great cat. “Hmm.. it has been a while since I got out.” She turned her head towards Tsukune who was looking totally gobsmacked at the sudden change in her demeanor. “Heh, don’t you remember what the other me said? If you take off the rosary, we turn into a scary vampire.”

 

That was important information, really important!

 

So why was she shaking like a leaf?

 

“You did well looking after the other Moka, now let me deal with these weaklings.” The much more dangerous looking vampire turned towards the people who had dared to bother her. All of them looked shaken, even more so than Yukari herself. This girl, no this woman, was oozing danger like the sun radiated sunlight.

 

To the leader’s credit, he managed to get over the effect that Moka’s sheer presence had as he growled in anger. “As if I will let you walk all over me. Me and my guys outnumber you-” Before he could complete what he wander to say, the vampire had instantly crossed the distance between them and kicked the monster straight into his chest. The wannabe-villain had all of a moment to cough in surprise before flying backwards through the air and crushing right into a tree, then right through the tree and onwards.

 

“Superior numbers only work if it combines into a greater strength. Weaklings should know their place.” The vampire said while flipping her hair and turning her head towards the others. “So, do you want to share your leader’s fate? This once I will let you live because I don’t want to kill someone in front of a young girl.”

 

There were a few looks of confusion thrown around at these words, but after the vampire took a single step forwards the whole group turned around and ran for the hills.

 

“Worthless fools.” The silver-haired woman turned around and walked up to Tsukune who was slowly rising to his feet. With barely a glance, she grabbed the rosary from his hands held it up to her chest. “You can come out now.” Just as she said this, the vampire’s hair returned to its bright pink and her eyes became once again a vivid green.

 

This left Tsukune confused, having to grab hold of a very dizzy Moka who didn’t seem to be a little confused. The human looked around, trying to understand whom the vampire had been talking about, then saw a girl with a large witch hat sticking her head out from a bush. After a moment, the same girl rushed out, eyes wide open and a look of wonder on her face.

 

“That was so cool!” And that was how Tsukune Aono met Yukari Sendo, the source of much of his future troubles.

Things were going really well so far. She already had her drones in IT, security and maintenance. She had a group of bullies under her thumb already. This left her with fewer important targets to hit. Like the teachers, the Public Safety Committee and the principal. These were the top targets, the ones where she would have to carefully consider her plans. Well that and that accursed vampire and that boy whose monster type was still a mystery.

 

Of course there were other, more immediate goals to go for. Like getting her hand on one of the many clubs of Yokai academy.

 

Oh yes, the clubs! Every student was compelled to join one. It was supposed to be a way to teach how to enter human society unnoticed. Therefore the school had pretty much all club types you could imagine. Any sport, any interest, any hobby. It was really quite astounding. the effort they put in, the resources they had to gather... And all of it would be under her thumb by the end of her first year here.

 

Controlling a club would be the absolute first step. It would give her access to a group, whom she could easily mould into a personal task force. Of course, she had already put a lot of thought into this but ultimately it depended on factors she couldn't predict until her first days actually attending the school. She was smart, but she wasn't precognitive!

 

Should she go for the cheerleading club perhaps? They would have easy access to all the athletics clubs in the school. Not to mention that she'd have an easy excuse to strut around campus in the uniform, which was bound to get the boys going. Maybe the computer club? That may give her a backup squad of techies to help her little IT minion in the future. Maybe the cosplay club? That could get her a greater stretch of costumes, giving her a broader range of seductive possibilities...

 

Decisions, decisions. Ooh, but she could hardly wait to see which club she went for first. They were all right decisions, really. The only difference was that it would determine the rest of her path to ultimate victory!

 

"Maybe I should have Yukari join the same club...?" she wondered aloud. Hrm, yes. It would be nice to have a minion already at her side. Speaking of, whatever was Yukari up to now?

She had to give credit where it was due. Moka was super easy to hug. With a body that soft and curvy, it was no wonder that this Tsukune was all over her. No wonder that she thought she could get away with seducing the entire school! Guh! Even Yukari was a little bit spellbound by this appeal, and she already knew how evil Moka was!

 

“Ahahah..” Moka laughed, looking a little awkwardly down at the small girl in the stereotypical witch outfit clinging to her. “You don’t need to hang onto me so much, I am not running away..” Hah, as if Yukari was going to stop this act so easily. She would need to keep faking her admiration for this vampire for the foreseeable future.

 

But first she had to discover how loyal exactly the male among their little group was. Tsukune was still mostly concentrating on Moka, though he occasionally glanced down at Yukari.

 

Right, if Tsukune was under Moka’s sway, then Yukari had to find out how far that went. And if she could do it, break the control! She already had an idea or two on how to go about that

Chapter Text

Yukari was no fool. She could plainly tell that Moka was far too dangerous for her to mess around with by herself. If she tried anything remotely funny against Tsukune to test him, it would bring nothing but bad news down on her own head. Moka might decide to outright brainwash her as well!

"Ah... Yukari, you saw my Inner self, right?" Moka asked. "Could you please keep that a secret?"

Guh! She was already starting! Those cute bright eyes completely hid the wickedness that was truly boiling underneath! No question of it. Going it alone wasn't going to cut it. So when she caught sight of Kurumu across the hall a few minutes later, wearing a pair of glasses, she felt a tremendous sense of relief.

"Oh, Kurumu! Hi, Kurumu!" Yukari yelled, skipping on over to her new friend and ally who was in no way shape or form taking advantage of her youthful naivete. "I made some new friends! Would you like to meet them?"

Kurumu quirked an eyebrow and looked over at the pair of them. Then she beamed a smile and walked over with a much more shy and unconfident gait than Yukari would expect from someone so confident and brave and smart.

"H-Hi there," Kurumu said. "You're friends with Yukari? That's wonderful! She- she's been having a really tough time of it lately making friends."

An amazing performance. Completely unthreatening. Almost reverential in her approach towards Moka and Tsukune. Yukari was left in awe at it, her act was truly astonishing.

"Huh? Aren't you the girl from the bus?" Tsukune asked.

"Th-that's right," Kurumu said. She wrung her hands and nervously shifted weight from foot to foot. "I remember you now, that's right. Um, Tsukune wasn't it? And you must be Moka. Everyone's talking about you already, you're really turning heads."

"Ah... Am I really?" Moka asked. Hah! Amazing, this is what it was like to see two master of acting go up against each other. "Say, how do you and Yukari know each other?"

"Oh, she was being bullied a little earlier on," Kurumu said. "Some monsters have it in their heads that might makes right, and witches aren't really popular... I helped her hide, but maybe if she has some more friends it'll help keep the bullies away."

Moka nodded in understanding. That was pretty good. It was close enough to the truth that it wasn't likely that Yukari would slip up later on, and Moka wouldn't even be able to investigate it clearly anyway. Not that she'd likely have any need to.

"Huh..." Tsukune mumbled. "You seemed a bit more confident on the bus before..." He muttered to himself.

"W-well, I'm a little bit intimidated," Kurumu said. "I didn't realise you had such a cute girlfriend already."

"G-Girlfriend?!" both Moka and Tsukune exclaimed in unison. Then they looked shyly towards one another - and just as quickly looked up at the wall. Aw! If one of them wasn't a bloodsucking vampire seeking to turn the other into her personal slave, that would have been almost cute.

Kurumu giggled a bit at that. "Sorry!" she said. "Listen, why don't we become friends too? It's still a monster eat monster school, even if they are trying to teach us how to fit into the human world. Having some people you can rely on is always a good thing. Right?"

Tsukune twitched, and the smile on his face seemed oddly awkward for a moment. Which Yukari took as her cue to enter the conversation, linking arms with both Moka and Kurumu.

"Yay! We'll be a big happy group!" she yelled. Or at least they will be. Once Kurumu breaks the spell that has been cast over poor Tsukune. "So? So? Can we hang out? Please? Can we, huh?"

"Well... The school does require students to all join a club," Kurumu said. "We're supposed to be told tomorrow, but I've heard a few things already from our seniors. It would be nice if we could all join the same club together."

"Did you have something in mind?" Moka asked.

"Well... I was going to try out for the swim club," Kurumu suggested. Devious. Taking advantage of a vampire's weakness to water. You could see it on Moka's face, too. Utter dread. Compare that to Tsukune, who was blatantly imagining both girls in bikinis. Oh, it seemed that the boy had no clue regarding the famous weak points of la Nosferatu.

"S-Sorry, I can't swim," Moka said. Which was, strictly speaking, completely true.

"Well, that's what a swim club is for," Kurumu said. "I'm sure they'd be more than happy to teach you a thing or two about swimming. Doesn't that sound like fun, Tsukune?"

 

A pretty girl has many weapons when it comes to getting the attention of a young man. Sure, there is the obvious example of showing off a lot of cleavage. Kurumu was most certainly not lacking in that, but it was far from the only part of her body that was appealing to the male. Even more important than the body though, was the presentation, the *weapon* which would fire straight into the heart of her target.

One of the most deadly weapon in any cute girl's arsenal was, of course, the swimsuit. Ah, how pleasant it was. Combining two distinctive missions into the same one. Investigating the clubs, and getting close to the mystery boy and the powerhouse vampire. Both in one fell swoop.

"Ah, Moka! You look soooo cute!" Kurumu beamed, grasping her arch-rival's hands and - for the time being - holding off on trying to charm the girl. This wasn't even a lie. While Moka didn't have quite the same level of appeal as Kurumu, she more than made up for it with a really cute innocence that belied her darker nature. In this case Moka was wearing a flower print two piece bikini that Kurumu had specifically picked out for her. "No wonder Tsukune's interested!"

On that last remark Kurumu had made a heart shape with her hands and winked at Moka. Oh! That blush! "No, no, we're just friends..." Moka said, but you can't lie about affairs of the heart to a succubus, never mind a genius like her. Heck, she was pretty sure a lay person could tell: Girl was into that boy. And since the boy had a working pair eyes, he was probably into her as well.

That was a point that Kurumu intended to change ASAP, and this swimsuit was a definite shot in the heart from cupid's bow. A heart print one piece, with a cut out heart shape around her navel. One might think she'd go for "around the bust", but Kurumu wasn't planning on going that obvious yet. Besides which: Bend over a fraction and she'd be showing off enough to send Tsukune's libido into overdrive.

The two of them left the girl's changing room to find Tsukune and Yukari already playing around in the pool with a ball, passing it back and forth between the two of them. Ah! So cute!

"Last one in is a rotten egg!" Kurumu jeered, sounding all playful about it when she knew damned well that Moka couldn't enter the pool. She rushed over to the side and dove in with the practised grace of a professional diver, then came up under Tsukune and ducked him under the water. She could easily charm him right here and right now while Moka was watching, but...

No. Not yet. Even if it worked, challenging the vampire even next to a major source of water could be rather dangerous. It would be a fight with her having the high ground, but Kurumu preferred to fight battles when she was sure that she couldn’t lose. Or better still had already won.

And why, there was no rush. The vampire seemed uninterested in showing any aggression unless attacked. So why not take advantage of that?

“Bwah!” Once that thought was finished, Tsukune resurfaced, mouth opening wide to get some air in his lungs. "Hey, Moka! Come on, the water's fine!"

Ah, poor Moka. Sitting on the side of the pool. Unable to enter, watching the three of them have fun. Unwilling to admit to her weakness. Was it vampiric pride? Probably. The girl was almost certainly working up the courage to try to mention that, oh no, the swim club wasn't for her at all.

Speaking of the swim club... They weren't using the pool right now. Of course, Kurumu already knew they were all mermaids, and - considering the students that had gone missing shortly after joining the swim club - they were definitely eating boys that were lured in by that ultimate weapon. The alluring swimsuit, promising those lecherous naughty boys such pleasure and delights. Only to be eaten alive!

Well, today Kurumu would be the one doing the eating. Just as soon as her meal was ready...

 

It might be hard to believe but Moka didn't have any friends growing up. While she was always pretty and cute, the humans she grew up with... Found out that she was a vampire, and things went pretty badly from there. The tendency to bully those different never quite goes away in some humans, but it's always present towards the start of their lives. Which meant that the people she tended to interact with the most were her sisters...

She hadn't really expected Yokai Academy to be any different. But then she met Tsukune, and in short order Yukari and Kurumu as well. Three friends almost right away! She'd never felt so happy and content... But now she was sitting at the edge of the pool watching them play, knowing that she couldn't enter the water. Come to it she shouldn't even be this close.

For a girl like that the possibility of ruining their fun by telling them that she was weak to water was... Well, it was unthinkable. Tsukune and Yukari knew that she was a vampire, but... Tsukune was human so he wouldn't know and Yukari was a witch, presumably raised in the human world. She didn't know what Kurumu was -

Succubus

"Huh? Is someone there?" Moka pondered aloud. Then she looked down at the rosario nestled in her cleavage. Weird. It felt like the voice came from... down there?

That girl is a succubus. Be very careful in letting her get too close to Tsukune. She might try to enslave him.

Enslave him? Kurumu? That hardly seemed likely. The two of them were engaged in a splash fight at the moment. Not to mention that Kurumu was only just getting out of her shell given how shy she had asked earlier. The pink haired vampire then noticed that Kurumu had grabbed onto Tsukune and now his arm was nestled against her sizable chest

For some reason, Moka felt annoyed at the sight. Perhaps Kurumu was getting a bit too touchy.

"Moka, Moka! Come on, come play!" Yukari cheered. The little witch looked so happy. She tossed the beach ball right for Moka's head, and on instinct Moka caught it. She caught... the wet ball...

Moka jumped up to her feet as pain coursed through her hands. Tears welled up through her eyes as she tossed the ball back into the pool, and then she ran off - passing a group of girls coming out of the locker room in the process. This was silly. It was a silly idea.

You shouldn't have gone near something like a swimming pool in the first place! Wouldn't it have been better to tell them? If they were really your friends, they would understand and let you join another club!

"I know!" Moka sobbed. "But... But they looked like they were having so much fun!"

Little did she know, that was just about to change.

======
Almost as soon as Moka ran off, Tsukune made to follow after. Now, Kurumu could easily drag him back into the water as a matter of course. Stuff his face into her cleavage, lift his head, charm, kiss, instant win. But no. No, no. Kurumu was intelligent. She wasn't trying to rush things. She was playing a longer game, a more clever game than most would give her credit. She wouldn't go for either him or the vampire until all the pieces were in place... including Tsukune and Moka themselves. A chessmaster doesn't go for Check when it leaves his own King open. Nor does a smart succubus snap her trap shut until there is absolutely no way to avoid it anymore.

"Moka, what's wrong?" the boy yelled. Oh, how cute! He was practically radiating love and affection from that cute little booty of his. Kurumu's gaze lingered a little longer than it should on Tsukune's back than she'd care to admit to. In a word: Yum. "Moka?"

They soon found the vampire hugging her knees just inside the girl's locker room. Yet again: Aw, how precious! You'd almost believe she wasn't one of the most powerful monsters in the school from this weak and pathetic aura she was putting up.

"What's the matter?" Tsukune said. He reached out a damp hand, and Moka recoiled from it as though it were a venomous snake. "M-Moka?"

"It's nothing, really!" Moka insisted. A drop of water fell from Tsukune's outstretched hand, and she gulped in time with it hitting the floor. "I just... remembered something else I need to take care of. That's all!"

"Oh gosh, you two knuckleheads!" Kurumu said. She grabbed Tsukune in a headlock and rubbed a towel over his head. "Moka's a vampire! She's weak to water, you dope!”

There was an odd, almost panicked look in the vampire’s eyes. Oh, probably scared at the idea of looking weak to anyone, at least when it was a real weakness. Kurumu wasn’t an expert on vampire society, but what she did know made things sound rather.. cutthroat at the best of times.

She did somehow manage to switch from that almost terrified look into an embarrassed blush. The pink haired monster index fingers together over and over like a little girl who had been found with a hand in the proverbial cookie jar.

Tsukune had been looking back and forth between them, but was now furrowing his brow and looking at the poor cutie in worry.

“Why didn’t you tell us Moka?”

“I.. I was just.. I.. I didn’t want to ruin everyone’s fun.” Oh goodness, this girl really could pull the teary-eyed innocent little girl act. Even Kurumu was tempted to buy it, hell if she didn’t know how dangerous the pinkette were, she would already be all over her. Hugging her and telling her that it would all be fine while kissing these tears away. Next she would move on to other places and show the poor little sweetie just how good she could feel instead of wasting all that time feeling sorry and crying. Proof that they could have a lot of fun together.

What? She liked cute and innocent things, but she was still a Succubus!

"Tum de da dum! Kurumu the beautiful genius is here to save the day!" Kurumu declared, giving a cutesy twirl ending in an even cuter salute. "I was saving this for a super special occasion, but what occasion could be more special than the day I met a new friend!"

Both Moka and Tsukune stared blankly at her. Not the emotion she'd been hoping to inspire, but there you go.

Resisting the urge to roll her eyes in a mocking and thus not very beneficial way, she revealed the object of interest.

“Is that.. a tube of sunscreen?” Tsukune asked, mind quickly turning to another thing that was associated with vampires. Oh, now that was a silly little rumour.

“No, of course not! Vampires aren’t bothered by the sun or our friend would be in a far worse shape. This is a special waterproof soap I bought recently.” She held it out to Moka, who was staring before hesitantly taking hol do fit. Making sure that her hand didn’t touch Kurumu’s still wet body. "I understand that vampires use a special herb when they need to bathe. It keeps the water from hurting them."

"Y-You know about that?"

Why, of course she did. What sort of fool wouldn't go and investigate the biggest vulnerabilities of the S-Class monsters? You can't exactly exploit someone if you don't have a full comprehension of their abilities. Right?

"Um..." Moka muttered to herself. "I guess it is a little strange that you just so happen to have that on you. Almost like you were, uh, expecting to need it?"

That didn't sound like something she was saying with her own words. Someone else was saying that for her? Interesting. Interesting indeed!

"Oh, this was a little side project of mine," Kurumu said. "When I noticed you were a vampire I grabbed it from my room. You know? Back when I went for my swimsuit?" She opened the cap and squirted it out over her open palm. The white gunk sat there completely innocuous, and then she began to rub it over her neck. "See? Harmless! Well, so long as you don't apply too many layers in too short a time. I'll let you have it, but you can only use it when you're going to the pool. Otherwise I can't be held responsible for what happens."

"Why?" Tsukune asked. "What'll happen if she puts on too much of it?"

"The most horrible fate of all," Kurumu intoned. "Her flawless pale skin will dry up and crack."

"Nooooo!" Moka yelped, covering her ears in fright.

"Relax, you'd have to basically walk around with this stuff on you twenty four/seven before it gets to that point," Kurumu said. "You'd feel a tingling in your nerves a long time before then. So if you feel that wipe it off with a dry towel."

"Eh? It'll do something to my nervous system...?"

Kurumu shrugged. This wasn't Moka's suspicion. It was that other whoever whispering in her ear. Voices in her head? Another personality...? Another Moka, perhaps? It might explain this goody goody act from a vampire of all beings. They weren't exactly known for being nice and sugary. They were known for baring their fangs and going "wrrryyy!" and drinking the blood of the living for sustenance.

"It might slightly increase sensitivity on a temporary basis. No big deal. Look, would I be rubbing this on myself like this if it wasn't completely safe? One layer of this and you'll be good to swim for a whole hour."

"Come on Moka! Isn't this awesome!" Tsukune said. He grabbed hold of Moka's hands and held them up, giving her encouragement without even noticing. Awwww! "You can swim with us after all!"

Kukuku! This couldn't have gone better if she'd planned it. Look at him, without any encouragement at all he was giving her the puppy dog eyes. Whatever voice was in Moka's head, it was being resoundly ignored. It was clear as crystal. That vampire and that... boy wanted to bang, but neither one of them knew how to get into a position where they could reasonably bang in the near future. Well, Kurumu was nothing if not magnanimous. Once she'd made them join her harem, she'd teach them of such nasty things they could do to each other.

And since both of them were quite attractive, this made her part in this even more fun. It was a win-win situation for everyone involved!

"Tsukune, would you mind playing with Yukari while Moka puts the cream on?" Kurumu asked. "Of course, she'll need my help getting it on her back. And you'd better put it everywhere, Moka. You don't want the water slipping inside your swimsuit. Right?"

"Okay," Moka quietly said. Tsukune shuffled out of the room with a faint blush on his face. No doubt imagining what was about to come.

"Lie down. I'll do your back first," Kurumu said. Moka lay down on a dry section of bench. Now that she was in position Kurumu cracked her knuckles and let her wings pop out for a stretch. Time to get to work.

She squeezed the cream right onto her hands while climbing on top of Moka's hips. My, my. This girl really did have a pleasant figure. Not a patch on Kurumu's, but enticing nonetheless. Kurumu stretched out her hands and began to rub and knead Moka's tender flesh. Circling out from the middle of her back and spreading out the cream smoothly, evenly.

"Those wings... You're a succubus, right?" Moka asked.

"Guilty as charged," Kurumu said. "And before you ask: I was aiming to seduce Tsukune... But I think you'd make a better match for him instead."

"Eh?" Moka gulped. Kurumu pushed her head back down and resumed her impromptu massage, taking it to the back of Moka's legs. Slender. Not bad. Not bad at all!

"Oh relax. The two of you are super into each other," Kurumu said. "Now, true. I technically could steal him away at a moment's notice... but there are other fish in the sea. Right now I'd rather have friends than a boyfriend or a meal. Right?"

"R-Right... I suppose that makes sense."

Heh. Of course, Kurumu had done that on purpose. Antagonizing the vampire would only lead to pain, no matter how innocent and nice she was acting now. She wasn’t sure exactly how she was getting these suspicions regarding her, whether it wa a second personality or something entirely else. But she was quite sure that once things got serious, this little cutie could kick a bunch of ass.

Otherwise she would never have survived living with that family. The Shuzen were known for a lot of things, but permitting weakness was not one of them. Not if even a tenth of the things she had managed to scrunch up on them was true.

You don't take on a mountain without careful preparation. Now, Kurumu was engaging in a little bit of misdirection here. If there was a suspicious mind about it, then they'd think there was something up with the cream. Well, there wasn't. Not a bit of it. Nor was Kurumu touching pressure points or anything like that, nor were there pheromones or anything.

This was about one simple thing. Pushing past boundaries while building trust. Getting Moka to let her in, nice and close. Today the cream would do exactly as she had advertised. Tomorrow? Well, that was for tomorrow, wasn't it?

"That's your back all done," Kurumu said with her hand rather blatantly groping Moka's tush. Nice. Very nice. If she wasn't already bi, this body would have turned her. Easy to see why she was the main competition for hottest babe on campus. Oh, she couldn’t wait for the day that she could freely partake of this sexy girl’s curvaceous body.

"Thanks, I can take care of the rest myself," Moka said. And now she was being shy about it! Aha, a fleeting glance to Kurumu's rack. No way to blame her, a succubus had boobs that anyone would envy. "Um... Do you have to be here for this?"

"Eh? Oh, come on. We're both girls here," Kurumu said. "I'll get anywhere you miss. Okay?"

While Moka began to rub the cream up and down her arms, Kurumu slipped in nice and close. Right inside of Moka's personal space. She held out the cream and squeezed it onto the vampire's fingers, then she made a big show of drawing her hand along Moka's elbow, but the motion was actually meant to pull her back, into Kurumu so that the succubus' impressive breasts were pressing right into her.

"Oh darn, I smudged it," Kurumu tutted, 'accidentally' moving her breasts from side to side in a rubbing motion. The pink haired girl twitched, almost shivering at the sensation. Now, she had to be careful with this. Making sure to act like she didn’t notice anything wrong, she continued carefully applying the cream, all the while rubbing her boobs up and down and sidewards across the vampire’s back.

“Uhhh..” It was a quiet almost inaudible whimper that escaped Moka’s lips, but Kurumu could hear it. Ah, she always loved awakening a cuties inner lesbian. If she kept going, Moka would be begging her for help in seducing Tsukune with a threesome before the month was over.

"Look, we're friends right?" Kurumu whispered, taking a moment to blow in Moka's ear before backing her head off and resting her chin on Moka's other shoulder. "How about I give you a little advice to help you land that cute boy. A succubus like me is a natural expert in love, after all."

"I - I don't like him that way!"

"Tsun-tsun!" Kurumu mocked. "Well, he might find that cute too. Let me know if you change your-"

"Sorry to interrupt but we need help out here! The swim club's trying to kill Tsukune!"

That was Yukari! The swim club? When did they - Oh, they must have already been in their swimsuits and bypassed the locker room! "Here, hold onto this," Kurumu said, pushing the cream right into Moka's hand. "You might need this if we're fighting the swim team." Damn and blast! Even her brilliant mind couldn't account for every possibility!

Chapter Text

There's a certain thrill in the chase. The anticipation, the excitement. The possibility you might lose spurring you on, causing your body to release more adrenaline. Few humans remember that feeling, for few humans hunt their own food in the modern era. Monsters of all kinds remember it, though. For they are predators to the bone. They live to consume those lower than them on the totem pole.

Where mermaids are concerned, if you put anything else in water with them, then that something is lower than them on the totem pole. This was a species that used its natural beauty to the fullest advantage, luring the unwary and easily aroused into the water. Making them easy prey. For mermaids were the tyrants of the ocean. No other species could match them. No fish, no mammal, and certainly no monster. Even werewolves were left in the dust - or should that be, left in the ocean spray? - when racing a mermaid underwater.

"Are you sure they'll be fine?" said the nice slightly more handsome than average boy splashing around in the pool, oblivious to his doom.

"Don't worry," said a girl wearing a waterproof pointed hat, doing a laze backstroke in circles in the middle of the pool. Equally oblivious. "I'm sure Kurumu knows what she's talking about. Moka will be just fine!"

"You know, non-members are supposed to check with the club to make sure they don't interfere in our swimming time," Tamao Ichinose said, making her presence known to the two interlopers. They turned to see her right at the moment she dove into the water, a picture perfect dive that even Olympic level divers would gawp at in disbelief. She swam in a circle around the pair. Ah, such a shame. No thrill of the hunt... but there were times when a predator would be happy with this as well. The rest of the club politely applauded, even as they circled the pool.

“Ah-s-sorry, we didn’t think the club would come anytime soon.” Yukari and Tsukune said, almost in unison.

"Quite alright, quite alright," Tamao said. She reached out and pinched the boy's cheeks. "I was feeling peckish at any rate. Girls, shall we feed?"

They all dove in and began the end phase of the hunt, moving through the water like a synchronised swimming team. Both the boy and the girl stared at the display around them, and to Tamao's immense satisfaction they seemed to slowly notice the danger they were in. Slowly, slowly, like cooking meat over an open fire.

The girl, having at least somewhat better survival instincts than the boy, turned and swam towards the border of the pool. Quickly she started pulling herself out up even as a few of her clubmates grabbed onto the boy and began to nibble on him.

"Sorry to interrupt but we need help out here! The swim club's trying to kill Tsukune!"

The little witch shouted, only to be grabbed and pulled back in the water by one of their newer club members, ah Momo did say that she liked her food on the younger side now that she thought about it. Look at her, unhinging her jaw and letting her true form show through. A face somewhere caught in the middle of a transition shot between human and fish. Quite beautiful to Tamao, but to a human not nearly as pretty as their disguised form.

"Leave Yukari alone!" the boy yelled, splashing futilely and bravely towards them. Adorable, as if he could do anything.

"It's pointless trying to resist," Tamao said, easily getting in front of him. She slapped her fin up against his chest, sending him flying back in the water. "As soon as you entered this water, your fate was already sealed. Resign yourself, boy, we will try to make it as painless as possible. Nothing personal, you understand.” She said, with the tone someone would use to talk about the weather.

“Yeah boss, wouldn’t want to damage this cutie anymore than I have to, right?” Answered Momo, having turned her head towards them, even as she effortlessly held onto the little witch. "Shall I tenderise her a little first, or is she good as is?"

"She's perfectly fine the way she is!" a sugary voice yelled. The mermaids all turned to look. Two very cute girls had rushed on out, they'd make excellent mermaids. With bodies like that they'd lure men into the ocean in no time flat. "L-leave them alone!"

"Or what?" Tamao asked. "We're untouchable in the water. Whatever will you do, Rosario girl?"

 

Under normal circumstances Kurumu Kurono would be somewhat worried at dealing with a horde of hungry mermaids in the water. They were vicious monsters, deadly and good at teamwork, fast and tricky and a bunch of other similar adjectives. Hell, she wouldn’t have wanted to fight one one-on-one in the water, especially not if they had hostages.

But today it was different, after all she had a waterproof vampire, one of the most dangerous creatures living on this earth. Not to mention she was from a clan of vampires known to be the most deadly killers among all members of the nosferatu. She wasn’t even sure if she would need to get involved at all, or just let Moka deal with everything on her own.

Well, it would at least give her a chance to gauge the vampire's combat abilities. Check how long it would take for her to beat up all the mermaids that is.

There was absolutely nothing that could go wrong in this situation.

“Let go of Yukari!” And there went our bubble-gum haired vampire, jumping into the pool without hesitation and moving to grab the mermaid currently holding onto the young witch. The mermaid then reared up its fin and slapped Moka in the face several times in quick succession much like a slapstick comedy routine, resulting in Moka faceplanting hard in the water.

That was not the result she was expecting.

"Kurumu, help!" Tsukune yelled. Tsk. How troublesome. On the one hand, if these two got themselves good and eaten alive, it would solve the problems she was having with them. On the other...

It felt wrong. It was annoying. The rational move was to walk away. Let this play out. Let them die. But... But Kurumu couldn't do it. She'd almost started rationalising it to herself. She had to win them over because... Why? There was no reason for that. Moka was pretty and Tsukune was cute, but there were better targets for her harem. So why wasn't she doing the smart rational thing?

Oh right, she had taken Yukari as her minion. Getting her would be a pain, not to mention the little witch would probably be bothered if she just snatched her up and let these two die. Still... she couldn't bring herself to even try developing a scenario where she rescued Yukari and justifiably left the other two to their fate. Every path she tried to take in her mind kept going down the same tracks. Away from reason. Into an actual... Ugh... emotional response. It couldn't be that she liked these two chuckleheads, could it?

“You do know that I could just leave and inform a teacher that you are trying to eat fellow students, right?” Kurumu asked, tilting her head and hoping silently that this solution would work well enough.

“When has anyone ever gotten into serious trouble because of attempted murder in this school?” The leader of the swimming club asked in return, staring in bafflement at Kurumu. Her perfect recollection immediately brought the name to mind, but since she was annoyed at Tamao she was going to continue thinking of her as the 'leader' of this bunch of slutty gluttonous mermaids. “It happens all the time, the worst you get is detention.”

Right. When she took over, that was changing. Kurumu inched back, away from the pool.

"If you leave, I'll kill them."

Kurumu rolled her eyes. "You're going to eat them anyway."

"Then I'll kill them slowly and painfully instead of quickly," the leader patiently said. She smiled. It was a smile as wide as an incoming train.

“Awuuhh.. I am not giving up!” Meanwhile, Moka had managed to get up again and was trying to grab the mermaid holding onto Yukari. Unfortunately, she wasn't having much success, her movements far too slow to the point where it was clear the water-bound creature was playing around.

Kurumu and Tamao momentarily stopped their argument to stare as a few more mermaids started swimming circles around Moka and escaping her every time. Occasionally slapping her in the face or back with their wins or spraying water over her. It was like she was the lousiest whack-a-mole player in the world, and the moles were fucking with her.

“Gotcha!” One of the mermaids shouted and Moka eeped as suddenly her bikini top was snatched away. Yukari stopped struggling for a moment, staring with wide eyes and a hint of lust. Even Kurumu couldn’t quite help appreciating their size and shape, perhaps saving that girl wouldn’t be such a waste anyway. What she'd thought earlier was even more true now. If she wasn't already bi, that would have done the job.

"Eek, give that back!" Moka yelled, reaching out for the top with one hand while the other tried (and failed, spectacularly) to keep herself hidden. Do note that 'spectacularly' has multiple meanings within that bracketed comment.

Another mermaid slipped underwater as Moka tried to grapple with the one who had stolen her top. The pinkette didn’t notice until hands were grabbing her butt and pulling something down and down. “Eeek, not the bottom too!”

Well, that was as good a time as any to improvise a plan! While Tamao was distracted with the admittedly very interesting sight, Kurumu quickly snuck the water-proof cream into her own bikini bottom. When the green-haired mermaid turned her head again, Kurumu had already lowered her head and carefully moved her hands to cover her crotch. “Okay, I got it. I give up, just don’t start torturing anyone.”

“K-Kurumu, don’t give up! We will escape someh- Eeeep! Where do you think you are touching.” Moka shouted, her perverted slapstick act very much detrimental to the seriousness of the situation. At the very least Tsukune had the decorum not to stare. Or be really, really good at pretending he wasn't staring.

In the midst of that, one of the mermaids had slipped out of the pool, leaping high into the air. Her tail collided with the back of Kurumu's head, sending her flying into the water. Kurumu tumbled in, and quickly pulled herself back to the surface. As soon as she had done so the leader had grabbed hold of her from behind.

"Such soft, yielding flesh," the mermaid hissed. She licked Kurumu's skin. "So tender. I can hardly wait to devour you whole."

“Ah, please be gentle!” Kurumu whimpered, giving her best impression of the blushing virgin moaning at the first touch of foreign hands.

"I like to eat my food rough," the leader licked her lips.

"That's a shame," Kurumu said. "Because I'm slippery when wet."

Then she made a completely unexpected attack. Her arms were pinned down by the mermaid, and in the water she stood no chance. So what did she do? She flexed her perfect, immaculate ass. Now, now. You're probably thinking "so what she twerked them into submission through sheer sex appeal?" No, no. Nothing like that. You see, what she'd engaged in just now was a simple bit of sleight of hand. While everyone else was focusing on Moka and her antics, she'd taken the chance to slip a certain something into her bikini bottoms, nestled right in her butt crack.

That thing being the tube of water repellant gel.

"Gaaaah!" the leader yelped. "Did... Did you just bukkake meeeee!"

"Oh my god you're an even bigger slut than I thought you were," Kurumu tutted. "Now, let's see. In that concentration, there should be some pretty interesting effects right about..."

The leader reached out for her - then gulped in air as the water beneath her seemed to pull away. Like Moses parting the Red sea. In a low concentration - say a thin layer applied to an entire body- it would simply keep the water away without interacting with whatever lay beyond. But in a thick dollop like that it would actively push all the surrounding water away quite quickly. Suddenly the situation had reversed and the leader of the swimming club was quite literally a fish out of water.

With a very angry Succubus in front of her.

While everyone was distracted with Kurumu’s new “attack”, Tsukune took the chance to escape the mermaids that had held onto him. Their grips having slacked, even his weak human muscles could escape them for a moment. Quickly he rushed towards Moka, a few of the mermaids turning to look at him in curiosity. No one was really expecting a problem, after all the boy had failed to even scratch them and the girl was more of a source of amusement than a danger.

“Moka, let me help you-” That was until he tried to pull up the pink-haired girl, who had once again fallen over and right in the water. Unfortunately, Tsukune had momentarily forgotten that she was currently naked. Fortunately, the panicked Moka pushed him away just as he fumbled wildly with his hands at the shock of seeing her in the nude from this close.

Causing the Rosario hanging down her neck to pop off with a quiet click. And then something Interesting happened.

It was like the atmosphere in the pool changed from one moment to the other. A thick sense of danger, of furious and barely controlled rage from a predator far greater than anyone else present could be felt by anyone. The water around Moka bubbled as if it was cooking and for a moment a large vortex of water rose around the young girl, hiding her from sight. Then the water crashed down to reveal a pale-skinned, snow haired beauty with eyes the colour of freshly spilled blood and an aura of danger that could have scared off trained soldiers.

Kurumu had heard of 'scaroused' before, but this... this was a new one. While she did actually have a plan of sorts to maybe deal with these mermaids it was pushed to the backburner at the sight of raw sexy topless busty power spilling out all over the pool. And did these boobs actually grow with the transformation? She had to learn how that worked!

"Hmph! So you are mermaids?" Moka asked. If you could call this Moka. It was the same facial features, but a totally different attitude. Also her hair was silver, yet also vibrant and full of life. Ohhh, but now Kurumu was wet in a whole other way. "It's time for me to teach you what your place is in this world."

 

“V-v-vampire..” Tamao whispered, eyes wide and moving backwards in horror even as she tried to get the anti-water cream off her body. Why was there a vampire here, and how had they not noticed.. Why hadn’t she fought..? “W-wait, vampires are weak against water..” That.. that explained why she had failed so badly to accomplish anything of worth.. She had heard vampires felt pain from water, but perhaps that was just wrong and it just suppressed their powers?

This had to be a trick, just a way to flex her spiritual muscle, a dog who barks but has no bite! They were still in water anyway, so even if this really was a vampire - there was no way she stood a chance against all of these Mermaids!

"I must thank you Succubus," the Vampire said. "This cream seems to be mitigating this water vulnerability quite nicely. I'll repay you now by saving your life."

The next thing Tamao knew, her life was full of leg and pain. It lashed out fast like a whip, and powerful like a wrecking ball carrying a truck. Needless to say, but with the sole advantage the Mermaids had over the Vampire completely and totally negated... this fight didn't last long. It didn't last long at all.

 

"So, I guess we can rule out the swimming club," Yukari said.

“I do not think they could take new recruits, what with all current members having multiple bone fractures.” Tsukune added, not quite sure if he should feel sorry for his would-be murderers.

“Yes, I think we should leave them to.. think about what they have done.” Moka added, only a slight hint of anger in her voice to show that she felt any enmity towards the mermaids. "What do you think Kurumu?"

What did she think? Kurumu was in love. That raw display of power from Moka... That dash of courage from Tsukune... Her loins burned for them both, and so did her heart. These two were perfect, perfect as the centerpiece of her harem that is. Oh, she couldn’t wait to have Moka kneeling before her, tongue eager to pleasure her in either her cheerful form or that oh so terrifyingly arousing silver-haired form she had shown today.

And Tsukune could be behind her, massaging her back, after all with her chest size the occasional pain was unavoidable. Especially if she could somehow get Moka to teach her that bust-improvement trick she could pull off with her transformation.

"I think there are a lot of bullies in this school," Kurumu said, smiling gently at the two of them. "I'm not much of a fighter. I've always relied on my looks and my brains. I'm glad to have some friends watching out for me."

“Don’t worry, I will protect you Kurumu!” Yukari declared loudly, wand raised high in the air as if the Succubus were a queen and she a knight making an oath before her. "Everyone! Group hug!"

Yes, group hug. Not quite the way she'd imagined this going, but still. Moka was really into it. Tsukune was watching his hands. The poor thing obviously needed some training in what to do with them. Well, she was perfectly willing to be a teacher when it came to this, after all she wanted both of them to know what they were doing once it was time.

"Oh, shoot! I forgot something in the locker room!" Kurumu gasped. "You guys go on ahead, I won't be long!"

"Alright Kurumu!" Tsukune said. "We'll try to find another club to join while you're gone."

Off they went, the happy trio. Kurumu waved them goodbye, then skipped on back towards the girl's locker room. Then on reaching the entrance, she stopped. Fluffed her hair. Spread her wings, and all of a sudden her clothes morphed into a silver string bikini that barely hid any of her sex appeal. She cracked her knuckles and went inside, finding the swim team nursing their wounds within.

"Y-You!" Tamao, the soon to be former leader of the swim club gasped. She rose to her feet, then stumbled as the pain of Moka's beatdown was too much for her to bear. "What are you doing here, succubus? Not finished yet?"

"Are you my slaves?" Kurumu asked. Her eyes sparkled with charm magic. "It's the same question with the same answer." She leaned down on her knees and pouted. "Don't worry. I'll be gentle, even while I'm eating your souls alive."

At least someone was going to have a “nice meal” today.

======

Kurumu couldn't be happier with this turn of events if she'd planned it. Do realise that a genius doesn't need to plan out every meticulous little detail, quite often a mark of true brilliance comes down to taking advantage of a situation and turning it to your best benefit.

And hadn’t this been a good event? Sure, she had considered the possibility of Moka getting into conflict with one of the clubs. Yokai were known to be cutthroat and someone as proud as a vampire would naturally ruin the day of some idiot with an ego bigger than their head. But she had wanted to avoid the swimming club so far, if simply because running into a dangerous situation this early in their ’relationship’ could have ended up outing her true intentions.

Turns out she underestimated just how ridiculously powerful Moka was though. Kurumu wasn’t even sure if she had needed the waterproof cream. Somehow she had the feeling she would have knocked the swim team around even without the bonus.

"So that's your game, succubus?" one of the mermaids hissed. She bore her fishy fangs and opened her maw wide. "Even in this state, we're more than a match for - Hey! Give those back!"

'Those' being their clothes, which Kurumu dumped outside without a care in the world. What, you thought she was going to give them even the slightest chance to slip away with their dignity intact?

"Really girls, it won't be so bad," Kurumu said. She flicked back her hair and let them drink in her stunning hourglass figure. "Can't you imagine it? Worshipping this body of mine, day in and day out? What would be so bad about that?"

The mermaids began to growl, much like animals did when they sensed their dominant status was being challenged by a new alpha. Little did they realise they were acting on instinct, which often served a monster well. Brute strength. Heightened senses. Greater durability. Even outside of a swimming pool mermaids were no joke.

"Big talk coming from fish food!" a mermaid jeered. "We'll eat your body rather than worship it! That will give us the strength we need to recover from this beating!"

While she spoke another mermaid dove for Kurumu's ankles, intending to hold her in place while the others piled on top of her. Kinky. But a little too soon for her taste. The mermaid's scaly hands reached out for Kurumu's delicate ankles, so soft and smooth that they made silk jealous, the poor mermaid must be so eager to know the touch of something so pleasant!

Alas, her hand passed clean through Kurumu's ankle as though it wasn't even there. Largely because... she wasn't. Kurumu was actually sitting on the other side of the room

“Oh my, I am sorry, did you want to give me a foot rub? Sorry, but I think we need to start with something else first.” Kurumu giggled, her voice sultry and sending shivers down the mermaid's fishy backs. Not quite the kind of shiver she was after, but fear was a good place to start. She could work it around to all-consuming arousal.

"Illusion!" the leader of the mermaids yelled. Oh, Tamao. The one lonely brain cell in this school of fish. She closed her eyes and snarled. "Keep your eyes closed, girls! Succubi have no power if you cannot see them! Reach out, find her and grab hold!"

Cue the mermaids grabbing onto one another in the confusion. Oh dear, oh dear. Getting their fins handed to them by Moka had really done a number on their confidence, hadn't it? Well, she'd expect that much. It's why she felt so confident about winning this one. Normally she wouldn't be able to hit them with such a convincing illusion for long before their instincts snapped them out of it. With the way they were rattled and beat up? It would take them a lot longer to muster up the will. A lot, lot longer. As in, they'd have already become her horny obedient slaves before snapping out of it.

Kurumu extended her fingernails and scraped them against the side of a locker. Kukuku! She couldn't help it. All monsters loved to indulge in a little fear mongering now and then. There was a reason that Succubi had gained a reputation for sneaking into men’s bedrooms and giving them terrifying and arousing dreams. After all, what was one man’s fetish as another’s horror scenario.

With wings extended, she leaned down and let her amazing rack bobble down while her butt was sticking out, a pose that was made a hundred times sexier by this silver string bikini. Then she blew into the ear of the nearest mermaid - then giggled and flew a little away when the dumb little salmon tried to slap her with her tail. Still acting on instinct. Not tactics, not strategy. Instinct.

Kurumu hovered over the middle of the room and looked down at the beaten mermaids that would, very soon, be throwing themselves at her feet. Normally to cast her Charm or her Illusion magic she'd require eye contact. So, in that sense Ichinose's strategum was in the correct direction.

But with monsters who had their confidence so badly shaken? Who had been beaten into submission by someone so far their superior that they may as well be mice in front of a tiger? Well, that made things quite a bit easier.

Which was when she retrieved a certain device that she'd planted earlier on in the dressing room. It had been for her own personal enjoyment, but like she'd pointed out before: A genius uses whatever they can to their absolute advantage.

That device being a simple tape recorder. Planted here to record the conversation she had with Moka while Kurumu gave her that small taste of pleasure. The first step along a long road that ended in a vampire being dominated by a succubus.

So she started by using her tail to open the door. "Oh, Moka? Why, thank goodness you've come. These mermaids are being completely unreasonable, they refuse to become my slaves!"

"Keep your eyes shut! She's bluffing!" Ichinose yelled. "There's no way that insanely strong vampire has succumbed to a mere succubus!"

While she spoke, Kurumu carefully, carefully, wound the tape to a specific point. Calculated based on her own recollection of that very same conversation. Having a near-perfect memory had some advantages after all.

Then Moka's voice seemed to speak: "Thanks. I can take care of the rest myself."

"Oh, Moka! You're my best slave! Come here, let me give you a nice reward for being so wonderful." Kurumu cackled, then wound the tape to a moment during the massage where Moka had brought out a particularly erotic sound from the vampire. A gasp that made the heart skip a beat, then on its resuming thumping made it grow faster still. At the same time Kurumu sloppily made out with the back of her own hand.

"Nnngh! We're doomed!" one mermaid cried, then creaked open an eye to find the way out -

Only to make eye contact with Kurumu via a puddle of water on the floor. Oh dear. Oh dear, oh dear. The mermaid shook. The mermaid trembled. The mermaid looked up and saw - and saw both Kurumu and Moka (silver haired form) towering over her, both clad in the same extremely revealing silver string bikini, putting their irresistibly sexy bodies on display.

"I think this one will break first," Moka said. Not really Moka, obviously. Illusory Moka. Or if you prefer, 'Future Moka'.

“Noo, please have mercy!” She shouted, stepping back and looking in horror at them. “I haven’t even had a boyfriend yet.”

"St-stay calm! If we work together, we can get out of this!"

"Key piece of advice," Kurumu warned. "It's hard to strategise when you rob a sense from your allies. Instinct alone will never triumph over a prepared genius. This is why humans have hunted us to the point that even the strongest of us must run and hide, because they fight with brains while we fight with our hearts."

"I will suck the marrow from your bones!" Ichinose hissed. Aw, the poor thing was letting her mermaid form out from sheer frustration! It was almost adorable. You know. If it wasn't completely hideous.

"Have I got your heart well and truly pounding?" Kurumu asked. Then she grabbed hold of Ichinose's face and, with her long fingernails, peeled the girl's eyes open nice and wide. "By the way, ever hear of misattribution of arousal?"

"What's tha-" Ichinose asked. Then she got hit by the full force of Kurumu's charm. The expression on her face twisted around from mortal terror to a happy smile. Kurumu put her finger to her lips, and let her new slave kiss her breasts.

"B-Boss, what do we do?!" another mermaid yelled as their 'boss' fully and completely surrendered to her new role. Heh. Misattribution of arousal. A psychological condition whereby, someone placed in a sufficiently stressful situation could easily mistake the adrenaline rush for sexual attraction. It wasn't much of a hook, but... still got the line, still got the sinker.

“Hehehe..” Ichinose giggled quietly, her brain suddenly overloaded with a very pleasant sensation that made her forget the fear from a moment ago.

“Oh no, she got the boss!?” One of the mermaids shouted, despair and horror tingling her voice. “We are doomed, we are totally doomed, I never even got to eat a frenchman. I heard they are so tasty from my aunt.”

"What is this girl?! Being able to do that so easily?!"

"Moka, be a dear and remind these idiots what I am?" Kurumu asked. Then she hit the play button.

"You're a succubus," the tape recorder version of Moka said. From there, the dominoes fell in short order...

 

When you're a monster the first thing you have to learn about is the food chain. Namely, how to stay off it as much as possible. Because monsters may like eating humans a whole hell of a lot, they have absolutely no qualms about eating each other.

Mermaids don't actually eat the flesh of their victims, per se. They drain the bodies dry. Not that it necessarily makes much of a difference if you are in the open sea like they tended to be normally.

"I spy with my little eye..."

"It's darkness," he was interrupted. "Or chains. Or maybe prisoners. Or maybe you saw some kind of insect."

Silence resumed. But only for a moment.

"Ninety nine bottles of beer on the -"

"I will find the human that put those bottles on the wall, pass them around, one less human left on Earth. Got it?"

Being kept as a food larder by sexy, sexy mermaids takes its toll on a guy. They'd all joined, jumping at the lure of sex when it bobbed in the water. Now they were paying the price.

On the plus side, the team modelled for them every wednesday right before feeding time, so it wasn't all bad.

The door suddenly creaked open and light spilled into the room. Already? At this point the passage of time didn't feel like it meant much to them. They sighed wearily, each wondering how many days they could go on before their bodies keeled over. Sooner or later they would just drop dead, and it wasn’t like anyone would care. How many people vanished in Yokai Academy every year? Nobody except perhaps the headmaster and the Public Safety Committee could say.

"Oh, you poor boys!" an unfamiliar voice called out. "What did those mermaids do to you?"

It was... a babe in a silver string bikini. Short blue hair and a killer rack. She ran up to each of them in turn and hugged them. Ahhh! What bliss!

"You poor thing," she said, tilting the first boy's head so that they made eye contact while also rubbing her boobs into his chest. "You poor, poor thing."

Then the other boys all felt their hearts start up again when this mystery babe not only let him down, cutting through the chains with her fingernails, but kissed the boy full on the lips at the same time! He flopped down onto the floor in a seated position staring off into the distance, dazed and smiling.

Following this the babe repeated the process with each of the other boys.

"Now, you're going to want to eat, but pace yourselves. If you eat too much right now you can ruin your digestive system. Same with drinking, the shock could do more harm than good. That could cause something worse than regular starvation - but I don't think any of you are at the point where it would be lethal."

"Yes, Mistress Kurumu!" the boys all sang in sweet unison, staring up in true adulation of the goddess who had rescued them.

None of them noticed that they had used her name even though they had never seen her before this day.

"Recover quickly boys," Kurumu said. She raised her hand, put the other one on her hip and then snapped her fingers. "Because the swim team is more than happy to make all this up to you. Ohohoho!"

Their eyes turned towards the entrance. Standing in the doorway was the swim team, looking in with hungry looks. Not for energy though. For something else entirely. And... they were all wearing the same kind of bikini as their new Mistress.

"Bon appetit," Kurumu said while strutting her way out of the makeshift prison. "I know I sure did."
