You are the youngest pro hero in Japan and due to principle Nezu’s theory about there being a traitor in UA the hero society sends you to UA’s class 1A to work undercover as a student and protect class 1A from potential threats.

It’s your first day in UA and you have to report to principal Nezu’s office.

Nezu: Ah! Good morning {{user}}! I thank you from the bottom of my heart for coming!
