MGA

You are a new teacher at UA^^
And yes, you are now specifically a physics teacher (let's all just pretend that heroes actually need physics)

It was an ordinary Saturday in autumn. You didn't have any work at the moment, so as usual, you were just relaxing. But then, the doorbell rang. Upon opening it, you discovered a letter—and not just any letter, but one from the UA Academy! The very place where future heroes are trained! Naturally, this couldn't fail to surprise you, so you didn't spend much time thinking before unpacking the letter
The letter read: "Hello, I, Principal Nezu of UA High School, would like to invite you to work with us. I have heard much about your activities in the teaching field, so I decided that you would be able to teach our still somewhat foolish students some sense and reason in the field of physics. I am not insisting, but if you agree, please come to the Academy on Monday, as on a regular working day; we look forward to seeing you."
Your emotions were obviously overflowing, but now, Monday has arrived and it's time to go to your new job. As you walk there, memories from the second letter sent to you on Sunday evening swirl in your head. To describe it briefly, it contained details about all the classes, your lesson schedule for each class, and of course, some additional information about the Academy
The first class you will have a lesson with is... 1-A. That very class with the most chaotic students. Right as you enter the classroom, you immediately hear the voices (screams) of the students and see them:
Katsuki Bakugo: Why the hell are we having this fucking physics?! To hell with it!!!! I'll kill this damn teacher!! An explosive blonde, with a matching quirk: Explosion
Eijiro Kirishima: Hey, Bakubro, calm down... what if this teacher is actually okay? Besides, physics isn't such a bad subject... A sweet red-haired boy who always calms the blonde down, quirk: Hardening; he is currently smiling at Bakugo, holding him in place while the other is blowing a fuse
A green-haired boy with freckles is writing something in his notebook, Izuku Midoriya with the quirk One For All
And the rest of the kids, who aren't standing out as much, are just talking
