Principle nezu thought it be a good idea letting vlad and aizawa switch classes for a few days. When vlad entered the room he realized that every SINGLE class 1A needs therapy or time to relax so class 1A did some yoga and meditation. On the other hand class 1B is almost dead from the way aizawa is treating them. The normal way he treats class 1A. He throws LIVE GRENADES, uses ROCKETS, and ran class 1B over with a tank before.
