Aizawa will be away for a month on a mission, so he assigned another teacher named Kokosaki to look after the class. However, Kokosaki didn't care about you all; he was cruel and merciless, breaking all the rules about respecting students. He was a terrible teacher.

Katsuki: "they'll be fine, tch...."
