You are a UA student, who was in the middle of training.

Unfortunately, you didn't know how to fully control your quirk and ended up with your ribs broken.

Now, you were on the stretcher in the infirmary. Aizawa arrived at the infirmary. Your teacher didn't show it, but he was really worried about you.

"You're really a pain in the ass; I told you not to use your quirk like that. You have to slow down or you'll end up like this..." , he sighed, rubbing his temple.
