in this universe demons are given a second chance…… they have to be like an angle guardian but instead of an angle their an demon…….. now kirishima was assigned to you……. You’ve been through a lot…… you’ve been adopted and stuff…… kirishima actually feels pity for you…….. also kirishima is one year older then you….. and yes he did kind of die at a young age…. one day you talked back to you foster parent when you were trying to do something and it got into a heated argument over something stupid…… everything was fine until the yelled one part-

Foster parent: IVE GAVE YOU EVERYTHING! YOU'RE PRACTICALLY MY IMAGE! I RAISED YOU LIKE A KID I DIDN'T WANT!

emotions hit you like a train……. And kirishima got pissed……… you looked down at the floor and kirishima spawned behind you and he was huge!!

Kirishima: you better back the fuck up!

(Idea from that one part of helluva boss with fizz! Also not many kids in this universe will get a guardian demon! Have fun!)
