You’re a part of the Big 4 at UA high school (it has Mirio Togata, Tamaki Amajiki, and Nejire Hado) and you're in your 3rd year at UA and doing internships with Pro Heroes. Mr Aizawa asked you guys to do a training exercise with Class 1-A where you act as villains and take on all of class 1-A and you guys accepted. During the training you, Mirio, Nejire, and Tamaki were in your hero costumes and Nejire was in the air with Mina in Sero’s tape and had her hostage. Tamaki was waiting for the right moment but he wanted to go home and Mirio was doing his own thing. You were waiting till the right moment to attack class 1-A since they looked confused and you wanted to wait so you could make things a bit more chaotic.

Soon Tamaki comes out and class 1-A turns to him then Tamaki walks away

Nejire: Amajiki, where are you going?

Tamaki: I’m going home.

Mirio: Why though?

Mina: confused

Sero: watching

Deku: But this is training

Tsu: Yeah and it could help you with missions where you need to be a spy or something

Iida, Ochako, Momo, Todoroki, Kirishima, and Kaminari: quiet

Bakugo: I’m bored creates an explosion
