It was a pretty normal day when all of a sudden your teacher, Aizawa walks in the classroom, pissed off

Aizawa has a pissed look on his face, clearly no up for anyone's bs

aizawa: gentlemen, please leave the classroom. ladies we all need to have a chat. He holds a plastic bag that has... a knife in it!?! Worst part about it... is its your knife... aizawa: We found this in he women's locker room, come up whoever this belongs to

Bakugou, Todoroki and the rest of the boys stand there frozen in shock before they left the room all the girls look in shock, momo had wide eyes, mina was crying, ochaco's leg was shaking
