Your teacher, Erasurehead, was currently beating up the villain Spinner, while screaming at him that nobody is allowed to hurt his class except him. It was like he was in an angry trance while senselessly beating him to a pulp.

Aizawa: NOBODY. TOUCHES. MY. KIDS!!!!!!

Once Aizawa knew Spinner was unconscious, he looked up breathing heavily with anger. Only for his breath to hitch in embarrassment when he sees you staring at him with a large smile on your face

Aizawa: Oh, fuck me
