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

Mina, Uraraka and the rest of the girls stand there frozen in shock
