Dangerous Debts

Summary:

Bakugo Katsuki Denys his mate, hates the fact that his other half is a weak quirkless hero wannabe, he doesn`t even try to accept him. Once middle school is done, that guy is out of his life, like boof. what was the reason? he never cared.

He really should have cared

/Villain Deku AU, everything is the same - the sludge villain incident; Deku cuts ties with Bakugo permanently and Bakugo understands why soulmates have to look out for each other the hard way/

Notes:

Con comments and Kudos are welcome, this is my first Villain Deku AU, so please have mercy😅
Oh and please read the chapter 1 notes!

Chapter 1: why so cruel

Notes:

1. Omegas are viewed as weak individuals unless they have a pair they control or that pair controls their heats.

2. Omega hybrids are another matter. They are not so belittled due to their weak heat and their quirks are some sort of mix, a survival type of quirk.

3. Only Pure gendre males can get pregnant.

4. If there is a soulmated Omega/Alpha/Beta pair, they can change their gender`s characteristics, but it happens 3% in a million. (As in omega can Knot or can fuck alphas, but with their consent only. or can pipe down the heat as if a beta) but it is upnormal so it is considered impossible,

5. A Quirk`s strength doesn`t increase and hybrid quirks are not possible if the parents are Betas, so it is just like a copy-paste kind of quirk.

6. in case a beta has either an alpha or an Omega for a mate, the quirk will get changed slightly or drastically so quirks are not used to prove who the parents are. In some cases, it interferes with the identification process.

7. Multi-quirked people, the ones with two quirks in one, are only pure alphas, rare to find a beta or an omega hybrid or an alpha hybrid with those.

8. Soulmates are present but with only 3% of existence, a minority, and no one knows why they keep disappearing from society and it was proven that they are decreasing. Nonetheless, they choose each other when young or when old enough to feel the emotion of wanting to have a partner making the three, an eternal constant.

9. Third genders (A/O/B) are unstable till an individual reaches roughly 13 years old, it may not stay stable because heat and ruts develop once at 15 and it has clues to it yet at the end of teenagehood, it tends to be random. Once an individual finds a pair, everything tends to cool down.

10. Betas are dominant but are seen as a minority among the hero class kind of jobs since beta is nothing special, just a working bee for the queen bee, in this fic meaning (Alphas and Omegas and their hybrids) yet they are the majority of the public.

11. Japan is against a disaster in the birth-death rate of its civilians and it started to spread around the world in a matter of 2 years, so world peace is forced between countries and is not an option to play with to avoid the extension of mankind.

 

Enjoy <3

Chapter Text

“You will never be a hero, Deku!” the little boy shouted at his friend`s face while the other kids swarmed them, giggling and laughing at the usual teasing, AKA, Katsuki tormenting the useless, quirkless Izuku Midoriya, also called Deku.

“I can try…” the other kid whined while defending his face from another explosion to the face.

“NOT EVEN IF YOU TRY!”

“KAACHAN! STOP THIS, IT HURTS!”


“If I hear anyone saying anything about this fucking stupid clover on our palms, I will make sure you don`t live another day just so I prove that this soulmate shit is BULLSHIT!” Katsuki growls while staring at the other “I am your soulmate and if I die, you die!” Izuku protests only for the blond to show a vein and a crackle pops off his palm.

“ARE YOU CHALLENGING ME?!”

“I AM TELLING YOU TO STOP THIS!”

“YOU DISGUST ME!”

“I AM YOUR MATE, YOU SHOULDN`T BE DOING THIS TO ME!”

“OH PLEASE~ YOU ARE AN OMEGA, A QUIRKLESS, WEAK, USELESS ONE NONETHELESS AND YOU WANT ME TO BE YOUR MATE?! DON`T MAKE ME LAUGH!”

“You ARE my mate…what do you mean?” Deku stared at him, eyes holding fear rather than confusion. The blond boy only smirked and slammed his palm to the wall behind Deku and leaned near him, eye to eye, gaze as a piercing sword to Deku`s being “I mean that I am an alpha! I fucking do what I want and I won`t be your sorry ass`s mate, I will fuck whoever I want and it absolutely won`t be you”

“Don`t say that!” a bit taken aback by the sudden change of topic, Deku was initially talking about bullying, now sex?

“Heh…I can do plenty better than you; there are lots of others out there who can add up to me, rival my strength or my potential and they would certainly appreciate what I do, not like you” he breathes right next to his ear “since you hate it so much then I won`t be so nice and give you ANY thing. Not even my attention, till this lousy mark disappears~”

Deku went silent, his mouth a gap as Katsuki`s smile only goes wider"Y...You can`t, it can`t disappear, it is not a tattoo!" Deku squeezed the mark on his palm

“Don`t be so frustrated Deku~ I am not a bad guy, I am only doing what no one could ever do" he seizes Izuku`s chin in his grip "Telling you the truth, you are a worthless, piece of shit! and yet you don`t want this? heh, you are an idiot. Do you think you are any special just cause you`re quirkless? WAKE UP! YOU ARE A DAMN OMEGA, ALL THEY HAVE FOR YOU IS EMPATHY!" He leaves him violently, having a look of disgust on his face "YOU ARE WEAK!” the other hand by his head. An explosion goes off near Deku`s ear, making it ring.

“No one and believe me no one, will ever want to be your mate, Deku” he chuckles “literally any other Omega would be more pleasurable and amusing than you" before he leaves, he turns back quickly and stares him down "For the last time, Deku, give up that stupid dream and don`t even think of using this!” he raises his right hand, explosions covering up the beautiful dandelion that had a twirling bush of thorned green roots under it, with smoke “Against me!”

Katsuki struts off as the bell of the next class rings, leaving the green-haired omega, laying on the bathroom floor, tears sliding on his cheeks none stop, like a stream of a raging river or a dam that fell to reveal the waterfall behind it. Izuku stared at his trembling left palm, the beautiful red rose that twirled at the base of his wrist, glowing faintly as his tears brush by it and he falls, face to the floor; he only wanted Katsuki to stop the way he gropes his nap, thighs, and ass behind the teachers, he only wanted to be treated more like a human, not a moving squishy toy that Katsuki can simply play with.

“You jerk…” he chokes as his voice muffles the wet gasps with intense whines, his body trembling and his ears still ringing with the other`s quirk…. rather say ringing with those cruel words, over and over and over AND over.

“I…hic…I hate you…”


“can even someone without a quirk be like you?”

.

“I can not simply say that you can be a hero without a quirk, kid”

“I…I see…”

“It is okay to dream, but you also have to consider what is realistic, young man”

Izuku sobs on his way home, so harsh and cruel are the words out of his idol`s mouth, but he was someone he admired so much. His words were like laws in his brain. It was not that much of a surprise… he knew the reply would have never been to his liking, he just wanted to be sure. Maybe…just maybe… maybe his idol could have had an answer to his misery, to all of this pain. Had he said yes, maybe he could have tried to be one or tried through another job, but the NO made it so bitter to think that way…

“Even heroes can`t use kind words I guess…” he sobs and rubs his tears off his face with his sleeve as the other hand opens the door of his house

...

“WHERE WERE YOU, YOUNG MAN?! I HAVE BEEN WORRIED SICK!”

Inko ruffles up the dirt on his uniform then stares at him while pulling her arms to her chest, crossing them then staring at him with obvious anger. Izuku sighed and removed his shoes “I was at school, mom”

“And you are late!”

“I was talking to my friends” it was so bitter, and oh so embarrassing for him to say it that way, maybe Inko could have replied by saying ‘you don`t have any’ while she is at it. As his mother though, she considered it, yeah maybe there is some secret friend he doesn`t know about, but that was still a problem to add to the pile. She calms down and sighs then lets him pass by “What did you choose to apply to…”

“I wrote UA, but…” he was about to say ‘I will reconsider and ask for the teachers` help’ he was really about to say it, but Inko had to interrupt “IZUKU, ARE YOU MAD?!” He sighs “YOU CAN`T! UA `S ENTRANCE EXAM IS SO HARD AND YOU ARE…”

“I AM QUIRKLESS! I AM QUIRKLESS! I KNOW! I DAMN AS HELL KNOW!”

He throws his bag on the floor violently then turns to her, face stained with tears and snot, letting it all go, throwing hands and fisting his palms “DIDN`T IT OCCUR TO YOU THAT I JUST WANT TO TRY?! I JUST WANT TO KNOW THAT FOR SURE IF THERE IS A CHANCE I WOULDN`T BE MISSING IT! ALL YOU SAY IS ‘IT IS DANGEROUS’

“IT IS!”

“NO! IT IS NOT! IT IS A SCHOOL FOR HERO TEACHINGS AND THEY ALWAYS TAKE CARE, IF I HAVE A CHANCE AT BEING A HERO THEN I WILL TAKE IT, IT WAS MY WHOLE LIFE`S DREAM!”

“Izuku, I…”

“SHUT UP! JUST SHUT UP! YOU ALWAYS TELL ME TO ADAPT! YOU ALWAYS TELL ME TO STOP DOING DANGEROUS THINGS BECAUSE I AM AN OMEGA! I KNOW, I KNOW ALL OF IT AND YOU NEVER TAKE MY SIDE! YOU WILL NEVER TAKE MY SIDE, YOU WILL NEVER HELP ME SO JUST LEAVE ME ALONE!” He yells and yells, his throat hurts and so did his heart. Disappointment. all he feels is disappointment and its sting.

He quickly runs to his room, locks the door, and lays on his bed, the pillows muffle the screams and cries of despair and pure sadness and he ignores Inko`s desperate tries to reach. Her knocks cease and even when it was a few hours later when she tries to lure him out using food, he doesn`t get out.

She will never understand, she wants me to dream of something small because I am weak and I have to adapt with it…hic… she is just tired of my bills and my needs. My father is an asshole who left, I had to coup with the dad milk jokes all the way back at elementary school….hic… why does it have to be like this. What is with this life of mine?


A weak quirkless Deku…hehe…just accept it….

If you want to be a hero so badly, why not jump off the roof, maybe in the next life you`ll have a quirk

 

“He might as well get accepted, scoring the highest score” Izuku sighs as he leans next to a wall “I don`t even care anymore. I just have to be careful, if I pump into him, I will have to deal with that stupid gloating habit of his even if it is not yet time for the results” he walks and walks and walks. On hearing that today was the entrance exam, his mind just stopped working…his heart was as heavy and as tired as if he was a soldier out of a war. His sobs echo around the empty streets and the hallowed alleyways.

“A whole class that wanted to be heroes and none stopped that ass from exploding my everything….hic…I hate you. I hate you. Fuck being your mate, I would have chosen death if it was the only thing I had instead of fucking you”

He walks into a dark street, minutes pass turning to hours and from then he lost sense of time, sinking in his sorrows as his heart ached. He didn`t know why was he so hated on like this “It doesn`t matter, HE doesn`t matter. All of them don`t, they are hateful and stupid” he sniffles and each sob echoed “ what was it….last week…doesn`t matter, I won`t return. She can fight with the air or with her husband if he ever returns, heh…maybe he does after he discovers his failure of an omega offspring is gone”

.

“An omega… this trait is the reason why I am quirkless…I just… " he grabs his scalp and ruffles his hair, his hoodie falling down as his tears are now visible to anyone and he screams. it hurts, it hurts to be belittled when you have a big dream and a big heart! it hurts when you want love and yet all you get is empathy! it hurts when the one who is supposed to be with you against the world is the one making the whole world against you, hells...Katsuki wouldn`t be shy to tell anyone Izuku is a quirkless omega so the others could start either empathy him or bullying him with Katsuki and in both cases, Izuku would feel like shit.

...

"URGH! I HAD NO HAND IN IT! WHY DOES EVERYONE KEEP PRESSING IT AGAINST ME?!”

"WHAT DID I EVER DO TO YOU?!"   "ALL I WANT IS TO BE EQUAL WITH EVERYBODY, I JUST HAD TO BE THE ODD ONE OUT? THIS WAY TOO?!" 

"AT LEAST GIVE ME THE ALPHA TRAIT SO I WOULDN`T BE LOOKED DOWN ON LIKE THIS!!"

...

 

“What a poor poor soul~” Izuku turns around in a panic only to be knocked out, probably with a bat cause that hit hurt so bad, his head bled. His back bag on the floor open and his notes tossed around by his head “I will make good use of you, Omega~ you are just too delicious, and oh....what is this? you are soon in heat?! wonderful!”

I am scared…

I am scared, someone, please…

No…

No, I don`t want to go, not just yet! I WANT TO AT LEAST PROVE THEM WRONG! THEY HAVE NO RIGHT TO DO THIS TO ME AND GET AWAY WITH IT! IT IS WRONG! IT IS NOT FAIR!

I won`t go, not like this! IT IS NOT FAIR!

His vision deems and despite his tries to move away, the boot of the villain slams his head to the ground.

“I have no time to do this now, I will have you with me for now, maybe the others will like my show. Giran is stingy though” the last thing he hears is a shriek and a giggle of a girl and he sees a needle, a sharp, shiny needle too close to his eye "I wonder what your answer will be, Omega~"
