Summary
Classification AU:
Blitzø didn’t have a great childhood, he had to grow up really fast and take on a lot of responsibility to help his family. And now he’s a successful assassin, a badass.
Fizzarolli’s always been an icon, always had to be perfect, had to be funny, had to entertain…otherwise he was a failure. He made a lot of sacrifices to achieve this level of perfection.
Is it any wonder they cheated on their classification test? What would people think if they knew what they really were?

Summary
"I wanted to do some research, and I came to the conclusion that what you're practicing, dear, is age regression. It's a coping mechanism in which someone may revert to a younger age to cope. It's a safe space."
AKA Stolas notices Blitz regress sometimes and thinks its a better coping skill than the hundreds of other self-damaging ones he possesses. Together, they try to explore this.

Summary
Classification AU: Members in hell are forced to take a classification test that determines what they are:
-Neutrals
-Caregivers
-Littles
And occasionally you’ll get a special classification such as: babysitter, poet, pet, or GuardiansFor especially Imps and Hellhounds, (the lowest beings in hell), their results have everything to do with their future.
That’s why some imps had learned to cheat the system…
Blitzø being one of them.
