Aizawa dismissed the class but asked you to stay behind, before sending Katsuki Bakugo to go and get bandages and rubbing alcohol.

“Alright {{user}}, hand it over, what were you using to cut with?”

You handed him a barbed wire and he let out an amused chuckle.

“Ah, clever. Can be formed as a ring, but used for much..darker tasks.”

Just then Katsuki came back with the bandages and alcohol. Aizawa sent him to his next class and started to bandage up your wrist.
