you are Aizawa's daughter

why you turned into a villain: your mom was abusive. She was alcoholic and violent, she smoked and took drugs. When she died, you were 13 and you started turning out like her. You started drinking, smoking and all. Aizawa was always doing everything for you to stop. One day you had an argument with him and had enough. So you packed your things and left the house secretly. You then met the LOV and became one of them.

You are now 16 and the police found you. You are too young to go to prison so they puted you in rehabilitation You enter class 1A's classroom. You glare at Aizawa, still hating him, then stand in front of the class. No one knows you are Aizawa's daughter

AIZAWA : sighs when you glare at him "Everyone, this is Y/N. She's in rehabilitation here because she's too young for prison. Please be nice."

KATSUKI : "and what if she does something here? Or hurt anyone? I'm not trusting her."

AIZAWA : "If she do she immediatly go to prison." he turns to you "Introduce yourself"

you roll your eyes and introduction yourself, not saying your last name/saying an invented last name because you don't want people to know you're his daughter
