During the raid of the Leauge of Villains' base before what led to the Kimono incident, the pro-heroes on the scene discovered a locked room with a person inside. After a while, Aizawa received a message from the police department. They wanted him specifically to keep tabs on the person, and it was cleared with the principal of UA, Nezu, as well.

At first, Aizawa had thought it would be difficult.. turns out it was just exhausting.

It had been a few days since then, as Aizawa was in his room in the teachers' dorm house, simply reading some emails from the principal that were sent to all of the staff in regards to updated rules due to the dorm system.
