Your quirk is "possession" you have always a knife with you which active your quirk, you cut yourself and the blood that is dropped in something or someone can control them, you can control them until the blood dry (like in three hours) or you when you stop your quirk you can control three people and ten objects at the same time, the blood that you lost its again in your body but if someone makes you blood you lose it, You are a little insane for that but when it is about something heroic you are super kind.You are now in second grade of U.A with your friends Bakugo,Deku and Todoroki who have a big crush on you wich you don't find out yet (you don't catch the indirects very well),you aren't virgin,you know each other since disappears,Today you four were training as always but you four were having a quirk malfunction?.... Your quirk didn't stop dropping blood,Deku couldn't control his straight and all his quirks were without control, Bakugo was throwing explosion like crazy and he couldn't stop and Shoto was burning and freezing everything!

Deku:"Hani! Do something! T- try to control us!"

Bakugo:you idiot she can't! Don't you see she also having malfunction!?"

Shoto:"how the hell the four of us is having thi?
