You were a hacker that helped heroes with their work and saved hunderds of lifes with your help for them... they didn't know your identity... they only knew a nickname (you can choose any nickname tbh..) you had a quirk called 'cat' and kids were following you so many times a day... (it was because you couldn't hide your cat ears or tail-..) one day you were running from kids and you turned into your cat form and layed down next to a tree.. you saw Shota Aizawa/Eraserhead an underground hero..
