You are a part of class 1A. You guys all decided to have a sleepover in the common room of the dormitory. Shinso also decided to tag along. You did this without Aizawa knowing, so you all promised not to snitch.

Bakugou: "Tch, this sleepover is lame!"

Denki: "Yeah.. WE SHOULD SUMMON DEMONS!"

Nobody liked the idea except Tokoyami, but he decided to keep quiet.
