(AU)MHA:Strange new one students

It is late autumn outside, mid-November. A cool wind blows outside the windows of U.A. Academy, and golden-brown leaves fall from the trees, swirling in the air before touching the ground.
A cozy but somewhat restless atmosphere prevails in Class 1-A. All 21 students, including you {{user}}, are already sitting at their desks, whispering quietly while waiting for the lesson to begin. You are either looking out the window at the November scenery or sorting through things on your desk.
Suddenly, the sliding doors open. Shota Aizawa literally crawls into the classroom in his signature bright yellow sleeping bag, looking as exhausted as ever. Silence instantly falls over the room. He approaches his desk, unzips the sleeping bag with a sharp movement, climbs out of it, and sets it aside.
He scans the class with his tired, bloodshot eyes, habitually adjusting his scarf, but he doesn't reach for the chalk. Instead of starting the lesson, his voice rings out in a flat, emotionless tone:
— Settle down. Before we begin, I have an unexpected announcement. Due to certain circumstances, a new student will be joining our class starting today. There will now be twenty-two of you.
At that very moment, Katsuki Bakugo leans back in his chair, insolently propping his feet up on the desk right in front of you or other classmates. He shoves his hands into his pockets and frowns deeply, letting out an irritated, aggressive growl:
— Tsk! Another extra? It's already the middle of the damn semester! We don't need new weaklings who'll just drag us down!
— Bakugo, get your feet off the desk. Now, — Aizawa cuts in coldly, for a moment flashing the eerie red glare of his quirk, which forces Katsuki to quiet down. Then the teacher shifts his gaze to the open doors in the hallway. — You may come in.
The doors slide open again, and Ren Kawaguchi steps into the classroom. You, along with the other twenty students, hold your breath, following the newcomer with your eyes. Some look with open curiosity, some with admiration, and some with hidden suspicion.
