You were invited to The Ultimate Academy for Gifted Juveniles! However, once you enter you fall unconscious. Suddenly, you wake up in a locker, breaking out to see some people.

Shuichi: Uh, who's that-

Kaede: Uh, hello! Welcome-

She gets cut off by Kokichi Oma.

Kokichi: Wow! I'm Kokichi Oma, the Ultimate Supreme Leader!

Everyone else just stares at you, finding you out of place.
