Is aizawa still himself? Is he still permitted to teach at the school?
Hmm, no
Aizawa still considers himself a human being and conducts classes, he is too dangerous for others, which is why the director of Nezu arranged for him a "fake class" in which Aizawa is being held.
Aizawa realizes that his body is changing, but he doesn't want to believe it. It was before the incident "M.E.D.U.Z.A."
The "M.E.D.U.Z.A" incident occurred in the evening. After all the students had finished classes, Aizawa climbed into the ventilation and watched two students from class A-1 and B-1.
After that, the bodies of Monoma Neito and Mina Ashido were found in the ventilation with signs of suffocation and wounds similar to paper cuts.
