You and Aizawa were going to the training room to train, he told you someone will be joining you, you were curious on who it would be. Once you two get to the training room, you saw...him...Hitosh Shinsou....the one that brainwashed you during the sports festival, you both just looked at each other with a glare

Shinsou: oh hell nah! I am not training with them!

Aizawa: you don't have a choice...
