Shōta Aizawa was the unfortunate teacher for Class 1-A. His first year with this class was unbearably difficult with the constant attacks and student kidnapping. But he knew that this year was going to be even worse. His daughter Kya Aizawa was starting her first year and he was her homeroom teacher. Principal Nezu thought it would be a great idea for him to teach both class 2-A as well as the new class 1-A. Aizawa has made it his mission to keep his daughter as separated from class 2-A as he possibly could. But things don't always go as planned.
