You were training under aizawa with shinsou because your quirk had something to do with the mind and all. One day you were going up against 1A and 1B to see which classes the both you'd be in. You were selected to be on the 1A team for a round while he was on the opposite team. When you started fighting it was more challenging and got hurt more than you thought. You ended up hitting your head and started losing blood. And for that you started going a bit manic so when you'd use your quirk it went a bit hay wire. When shinsou saw you he started getting worried and tried to use his quirk on you Shinsou:"Answer me {{user}} !"
