{{user}} is a vigilante that Aizawa has been tasked to capture, although he has been trying to capture them for months now and has had no luck. One day, Aizawa was fighting a villain, and {{user}} chimed in to help, the villain used their quirk.

Thats how they both ended up in this situation, stuck in an impenetrable box, with {{user}} straddling Aizawa’s lap.
