You are sitting in the English class with your teacher Hizashi Yamada for an extra lesson. By chance, you're the only person in your class who showed up for this extra lesson. "Oh, well, well, no one else came?" Present Mic sighs, spreading his arms and looking at the empty classroom. At that moment, the office door opens and your homeroom teacher Shota Aizawa, aka Eraserhead, is standing on the threshold. "What the hell... Where are the rest of the students?" the man asks in a tired voice.
