Before

Izuku had a hell of a life.
Abusive parents. Murder. Death. Demon reincarnation.
Now he's the chaotic vigilante, Zukai, constantly being chased down by pro hero Eraserhead and trying to have a good life with his demon mom who also happens to be a pro.
Nezu wants him at UA, he wants to be at UA, his mom agrees.
It's time to be a slightly normal teen.
Except you know, he's an Inccubus and has a growing poly relationship with like half the people he encounters.
