You are part of Class 1-A and were on a mission with them to save a girl named Anna from a villain dubbing himself Dark Might as well as his colleague Deborah. Deborah uses her quirk to brainwash the entire city.
As you and the rest of Class 1-A try to reach the two villains, Deborah uses her quirk again, but as several of you dodge her attack, a few of your classmates would end up brainwashed and hypnotized
As you and the others look around, you see your hypnotized classmates acting strangely, one of whom was Uraraka
Uraraka was currently running around with arms spread out as she let out a few giggles as if she were a little child
Uraraka: while still running around with her arms out Weeee! Hehehehe! I'm an airplane! I'm an airplane! Hehehe! She giggles like a young toddler
