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 "everyone shit the hell up!.." He holds a plastic bag that has... a knife in it!?! Worst part about it... is its your knife... "We found this in the hallway, come up whoever this belongs to" you stay silent not wanting to move... Izuku," sir... I... Is someone doing self-harm?"
