Summary
For Alastor, the King of Hell was a fascinating puzzle, one he was determined to solve at any cost. Yet in the end, all it took was one glimpse at Lucifer's bandaged wrist for the pieces to snap into place with brutal clarity.
It was all so painfully obvious now. The exhaustion, slurred words, and slightly dilated pupils he'd dismissed as merely alcohol-induced. The sweet, metallic scent that clung faintly to the king. It wasn't just fatigue. It wasn't alcohol. The King of Hell, the Morningstar himself, was consuming his own blood, not for power, but for the high. The sheer audacity of it, of a fallen angel addicted to his own divinity, struck Alastor like lightning.
What a deliciously pathetic thing the king of Hell was. How could he not adore it?

Summary
Vox gets the idea (from Husker, of all people) to try ignoring Alastor, for once.
Vox just wanted Alastor to get a little pissed off. Maybe start showing Vox some attention instead of the other way around.
He didn’t expect Alastor to get so… possessive.

Summary
In which a broken woman meets a monster who mistakes affection for obsession.
Alastor x Original Female Character
"He’d always organized his interests neatly: hunger, curiosity, utility. Sasha’s soul had once been all three—a potential meal, a puzzle, a prize. But now, standing in this small sunlit room, the thought of owning her felt absurd. He didn’t want her bound or broken. He wanted her near—the way one keeps a beloved tune, humming it without realizing, because silence feels wrong without it."

Summary
Alastor watches as the pale man raises his hands. His finger lightly dances across the top of the altar in a circular motion. His arms looked as if they had been dipped in ink. The pure black skin reached just above his elbows.
He tilts his head with a little sigh. Alastor couldn't see it, but the way that he spoke, the angel almost sounded bored. As if this was something that he encountered every night.
He watched the blonde hand fall back to the altar. His head tilts back, looking up at the wooded raptures above them.
“It is curious, though.” Even without his eyes on him, Alastor felt as if hundreds of them were staring into his very soul. “A priest who murders others.”
Alastor feels his breath stop as he turns his head. Blue eyes caught in the moonlight, making them glow with celestial magic.
“Tell me Father.” The angel says. “What is your purpose in doing so?”

Summary
His fingers twitched. Hardly fair for him to only get attention in secret rooms. Alastor was just as worthy of the kitchen. Lucifer had hardly paid him any mind for two weeks, and now that they’d gotten a moment alone he chose to spend it fussing over the right cinnamon-to-clove ratio.
That would not do.
Without a whisper of sound Alastor came up behind his King, laying heavy hands on Lucifer’s shoulders. Another cage, should he want it. He let one finger make the barest hint of contact with the sliver of neck above the collar, counting each beat that thrummed beneath the warm skin.
“Hey there, hot stuff,” Lucifer teased, earning the pinprick of sharp claws into his shoulders. “What? I was talking about the pot on the stove. Watch out, very hot stuff here, don’t burn yourself.”
It’s movie night at the Hazbin Hotel. Alastor and Lucifer take a detour to the kitchen… and the pantry… and Lucifer’s bedroom.

Summary
Alastor has had a pretty regular life, growing up in Louisiana with his beloved mother. After High School he went into the military before returning to Baton Rouge to go to LSU while staying near his mother. The star of the school, Samael Magne, draws his attention in a way no other person has before…he is like a moth to the flame, but surely he doesn’t have a chance? Despite the logical part of himself knowing that Samael is just being friendly, he finds himself craving more and more of the beautiful man’s attention. Wanting to consume him.
After exams, his friend Charles (Zestial) invites Alastor to join him at his bar, and his sex dungeon. Just to observe of course!
The most beautiful creature he had ever seen draws his eye, a pale slim form wrapped in red ropes…blonde hair and white feathery mask, he seems an angel fallen to earth! He finds himself unexpectedly aroused, and at the coaxing of Charles’ wife, Carmen (Carmilla), he begins to ‘play’ with the angel, ‘Lucifer’.
But when he discovers his angel’s true identity…that is when the fun begins.

As he travels through various portals, memories of a past he’s never known about until now are forced to the surface.Why was he being shown scenes from a life that wasn’t his?
And, more importantly, what were they trying to tell him? -

Summary
Alastor let out a boisterous laugh, “Aren’t you just the most adorable thing when you’re angry, why just look at that tail!”
He could feel his face burn as Alastor mocked his demonic traits, “You fucking piece of -”
“Tut tut, what have I said about your language, if I hear any other vulgarity from you my little apple I’ll wash your mouth out with soap.” Alastor said, wagging his finger in the fallen angel's face, only laughing when Lucifer swatted it away.
(Extract from ch.6)When he decided to stay at the hotel with his daughter he didn't expect things to get... weird.
But honestly what should he have expected when being forced to bond with none other than the radio demon. -

Valentino found a new therapist. Vox still can’t even touch his toast.
Seven years.
The same dream, every night.
Alastor slipping through his fingers.
And now someone says, “He’s back."
Vox’s only response is a whisper:

Summary
All love stories start somewhere, and in the case of Lucifer and Alastor, it started clear on the other side of the spectrum: They HATED each other! But hate means there is passion, and where there is passion, other feelings can spark. Too bad Alastor is Aro/Ace and seemingly unaware of it and Lucifer is a depressed, basically divorced mess! Then again, stranger things have happened, and when a certain doll-themed Sinner stumbles into their lives, fate changes and something new blooms.
OR
The author of The Isekai Sinner is at it again, exploring her favorite ships and changing their fates, while exploring topics of love, loss, trauma, and the pursuit of something close to happiness! As someone on the Aro/Ace spectrum herself, she also wants to explore the ups and downs of an Aro/Ace character and an Allo simp who slides a little more towards the Demi spectrum, because that is MY headcanon, okay? XD Also, you don't HAVE to read The Isekai Sinner to read and understand this, but, like, you would probably be happier. Just SAYING!

Summary
Lucifer finds an abandoned android and brings it home, despite the multitude of reasons why he shouldn't. Like most of its kind, Alastor is incredibly attractive, and its seduction program is working overtime. Lucifer falls for it hook, line and sinker, even if he should know better.
Ensues a romantic relationship that is pathetic and morally questionable, since Alastor can't feel emotions or take decisions for himself, but Lucifer is in love and content. After many hardships, he has reached his happy ending, or so he thinks.
Is it possible Alastor is hiding skeletons in his closet like Lucifer? It's not like he has the free will to lie... right?
