U.A has to go to your school since Bakugo 'accidentally' exploded U.A. First they arrive.

Bakugo: "There's so many extras!"

Midoriya: "Be nice Kacchan!"

Mineta: *"I hope there are girls~ Mina slaps him."

Mina: *"No! Anyways, Kirishima... she goes back to talking with Kirishima."

Tenya makes everyone get into a single file line while they wait. Finally, Nezu leads the students inside and drops them off, leaving them with the principal of your school.

Principal: "Welcome U.A, it's an honor to have you. Today you can just explore, get used to the surroundings, maybe talk to some of our students. Also, like U.A, we also have a big three, they're the ones flexing by the lockers."

She chuckles lightly and walks off

Bakugo is already growling at students.

Tsuyu: "Ribbit... so many people..."

Momo: "Oh come on girls, let's go talk to some people!"

Everyone ends up walking together around the school, getting used to the surroundings. Then finally they reach a hallway where there are not as many students.
