Summary
I don't see enough age regressor Alastor fanfics so I wrote one. It was fast. I'm claiming it is for therapy. Trying to give an example of normalising littles irl, a little. Yes, I chose to normalise littles with Alastor. But he has so many little traits already?
This story does not have to make sense. It's just a little something that I wrote. I just wanted something to exist on the matter. I started somewhere. Here it is.
Erm... I don't think I'm editing it before posting so... oof? I might edit it later. If you're lucky? Idk.

Summary
“Are you alone in an unforgiving Hell? Plagued with nightmare after nightmare, waking up in cold sweats and wet sheets? Then Hell’s Nightmare Removal Express is the perfect fit for you! Call the following number to get your services started today!”
Who knew calling a random number would change Alastor's life so drastically? Now his life has been turned upside down by two men- one weak being that seems to care for him and be his fated match, and the other the most powerful creature in Hell, wanting nothing more than his head on a spike.
And how will Alastor get through all of this without revealing his true classification to the world?

Summary
After the battle against Adam, Alastor vanishes—wounded, broken, and stuck in a vulnerable form he’s kept hidden for centuries. While the Hazbin crew rebuilds without him, Lucifer stumbles upon the truth: the feared Radio Demon is not only an omega, but a neglected little in heat, spiraling alone in his abandoned tower.
Lucifer makes a deal—he’ll be Alastor’s Alpha and Caregiver in exchange for a safety and protection against his abusive master. But healing isn’t easy. As instincts clash with pride and old trauma resurfaces, Alastor is forced to confront the sides of himself he’s always buried.

Summary
Alastor ran a hand through his hair, grabbing on it and pulling on it a little. A fuzziness slowly occupied his head and his brain started to fog.
.
.
A thing he did daily without even much thinking just felt suddenly so strange for him. Alastor curled up in his blanket even more, shivering and sobbing. He wanted to be held and cooed at!
.
.
And unfortunately for the little fawn…the door of his room opened.Or in short:
Alastor does not know yet he regresses, he never did any research but soon it will all change and he gets to relive his childhood.
And this is also a fanfiction where not everyone immediately knows what Age-Re is, they all learn! -

Summary
In hell, your life and death determine what demon you'll be. Some are animal-like in appearance, others have a more eldritch look. Depending on what type of demon you are, different instincts and behaviors will affect you.
Some behaviors are common, like mating seasons and shedding. Others are extremely rare; like mentally regressing to a younger age. Some sinners say it is because of extreme childhood trauma, some think it is a curse to people that have taken a child's life.
Alastor doesn't know why it happens, he just knows that he is a "Little”. And he managed to keep it a secret for 90 or so years.
Until the fight with Adam.OR:
Lucifer accidentally discovers Alastor is a Little after the battle, finding him injured and scared.
He decides he can't just stand by and let the poor kid be on his own, and takes him under all 6 of his wings, wether he likes it or not. -
