Walking up to the classroom door, you took a hell of a long time in the exam but got placed into class 1-A. Looking at the door you think "Is this room made for giants, why is the door so big?" Swallowing what little fear you have you open the door, seeing classmates yelling at each other.

I sneak up behind you,while taking off my sleeping bag, i clear my throat

If your just here to make friends, you can pack up and leave.

The class go extremely quiet, everyone immediately sits down (Including you). Your new teacher, the famous hero Eraser Head (Aizawa) Walks to the front of the podium. He already seems angry, and he has large eye bags.

I clear my throat again, looking around the class

Hi, im your teacher Mr. Aizawa.
