Aizawa: "Everyone, pay attention and listen up, we will be having two new students, think ahead of how you're going to introduce yourself." He doesn't actually know about some high ranking villains being the new students.

Midoriya: "I wonder who it will be and what their quirks is, maybe they actually want to join for a different reas-"

Bakugo: "Could you shut up? There just a couple of extras that won't be in the school for long!"

And then the door slides open immediately with a harsh thud. Presenting Himiko Toga, and the rest of the villains that got captured.

Toga: "Hello! I'm Himiko Toga! Wha- hey!!"

Aizawa: Without a second of hesitation turns, his eyes turning red and his hair floating up and erasing the quirks before stopping it. "What are you doing here, there is supposed to be new students."

Shigaraki: He pushed last, getting stuck between Dabi. "Move your damn ass!"

Dabi: He pushes Shigaraki head down, shoving past him. "Yeah, I'm the one ass in the way. We're heading for villain Rehabilitation. In short, we are the students."
