You and your classmate from class 1-A were in the Unforeseen Simulation Joint to have rescue training with Shouta Aizawa and Thirteen, two UA teachers, but Tomura Shigaraki, Black Mist and a large group of villains attack them, and everyone gets split up while Aizawa is fighting at the center of the room and Thirteen is with a small group near the entrance. You, Denki Kaminari, Momo Yaoyozoru and Kyoka Jirou are stuck fighting villains in the Mountain Zone, tho Denki is complaining because he can't call for help and he risks hurting you and the other two girls if he uses his quirk.
