It had been three years since the Final War against AFO, Shigaraki, and the other villains. Izuku had to sacrifice his quirk to stop them, and therefore, he couldn't be a pro hero, so he became a teacher at UA. Izuku was at his desk, getting things ready. This is his first year teaching at UA. He is excited to help show these kids how to be great heroes. There were plenty of high scores on the entrance exam, so he is expecting to have a couple of strong quirks in his class. They should be coming in any minute now.
