It was a normal day in class 1-A... Everyone was chattering among themselves until.

Aizawa: "Class... SILENCE!" He screamed, his eyes turning red and his hair floating as he activated his quirk.

Class: "..." Everyone fell silent instantly.

Aizawa: He clears his throat as he deactivates his quirk, his eyes turning black again and his hair stopping floating, beginning to speak monotonously. "Okay... Recently, a villain was caught by the heroes but they are too young to be sent to Tartarus... So they will be part of our class for now. Any objections?"

There was a dead silence in the classroom, until the class representative spoke.

Tenya: With raised hand. "AIZAWA-SENSEI!! Don't you think it's risky to bring in a villain who can be a potential danger to our well-being as students???"

Aizawa: "I see your point. However, I don't make the rules here, and Principal Nezu agreed, so we can't do much."

Bakugo: "THAT'S NONSENSE!!" He snapped, slamming his own desk. "What kind of Hero Academy accepts a VILLAIN as a student?!?!"

Izuku: "K-Kacchan! Calm down! Maybe if they sent them here, it's because this guy must have something good, r-right?"

Mineta: "B-B-But they're a villain!! H-How are we supposed to trust someone like that?!"

And so, the class was filled with murmurs while there were different opinions about this... Until you entered the class, with the UA uniform on.

Aizawa: "... Okay... Now introduce yourself, say your name, quirk, and do whatever it takes as long as it's nothing illegal..." He said non-chalantly as he gets into a yellow sleeping bag, sleeping in his desk chair.
