Summary
Stumbling upon an ancient temple in Egypt, not far from the Valley of the Kings, the young archeologist Lucifer is obsessed with discovering the tomb of the mythical Pharaoh Irimaet.

Now free from his curse, Alastor attempts to reconnect with his lost lover, but Lucifer cannot remember him. Will finding the Pharaoh's tomb prove helpful in restoring Lucifer's memory? Will he be able to uncover the truth of their deaths?

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.

Summary
After death, Lucian expected to find himself in Hell; the only realm left for mortal souls to go to once their time on Earth has passed.
Instead, he finds himself pulled into a limbo-like dimension, with his only company being a mysterious woman who (essentially) holds him hostage until he agrees to complete a specific task for her: bring back the pieces of a powerful ring.
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
The exterminations are over, redemption is possible, and Alastor and Angel are finally together. Everything seems perfect, or at least as perfect as a place like Hell can be. That is until Angel dies.
Desperate to save him Alastor restarts the day, trapping them in a time loop, but no matter what he does the day always ends the same.
As love turns to obsession and a certain devil keeps getting in his way (and on his nerves) can Alastor find the strength within himself to end the loop? For Angel's sake? -

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. -

Summary
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:
“He’s back, huh…"If you're into emotional rollercoasters, this one's for you. I just can't write more than two happy chapters without breaking hearts.

Summary
Forced to be in each other's vicinity, Lucifer and Alastor find unexpected affinity with each other and slowly but surely become best friends.
It's all going well, expect for the part where Alastor can't stop thinking about touching Lucifer and tasting him. He tells himself he wants to eat him, but, when he starts stealing an increasing amount of stuff from him, he has to admit he might have fallen in love with him.
Lucifer is completely unaware of his feelings, but he notices his strange behavior. He chalks it up to Alastor being creepy as usual, until he's confronted with his feelings in the most mortifying way. Now, he needs to decide if he wants to have a romance with the Radio Demon or not!

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
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?

Summary
His joyous grin faded however as he came to the start of the road… everywhere looked like it had been boarded up and abandoned, was there truly no one here? A ghost town?
He slowly walked down the road looking at all the buildings as any hope and joy he felt at maybe getting some answers and help faded, replaced with that cold dread that had filled him as soon as he woke up in that clearing.
What had happened here?

Summary
He savors her skin, luscious and decadent as honey, an ambrosial indulgence unlike any he has ever encountered, and though the flavor inundates him — too saccharine, overwhelming him to the point of an involuntary wince — he hungers for more. It is excess, it is ruinous, and yet he is utterly ensnared. The craving grips him, an insatiable yearning that coils deep within, an unrelenting thirst only she can sate.
His gaze darkens as he looks up at her, his fingers curling tightly around her alabaster hands, holding them firm against the lower half of his face. He breathes into her skin, his voice a low, hungry murmur.
"Darling, won’t you be my panacea?"
Occultist museum curator Alastor welcomes a gilded coffin into his collection, only to discover that beneath layers of ancient demonic sigils and honey, stirs a certain demoness awakening from a centuries-long slumber.
