Day 1: Izuku Time

Truth be told, Izuku never chose this school. He wasn't a fan of schools that held their noses so high, the only thing they see is their own backside. But All Might suggested that it would look good on his file when he applies to UA next year.

Or at least it would have if he hadn't landed himself in the dreaded Class 3-E. 

How, one may ask? An act of mild violence, surprisingly. 

A button was pushed, so Izuku pushed back. And of course, the quirkless kid was held accountable for the stupid bully being uncomfortable sitting on his backside like a dunce. Staring at him like he was about to murder him. Izuku was surprised to realize there was a smidge of desire within himself to do just that. 

Just a smidge. 

It was almost the end of the year when he was suspended. A few days later, Akabane Karma was suspended for beating this one kid within an inch of his life. Izuku silently applauded him when he heard about it. The green haired boy returned to school on the first day of the new school year in April, entering the ashamed Class 3-E.

A gun was placed on his desk, the bullets made of a non-lethal material (to humans, anyway) and a task to kill their homeroom teacher within the year. Nothing from this felt right, his stomach tight & twisting—feeling worse when he learned All Might was teaching this class as well. 

When the unnamed teacher stepped into the room and introduced himself, he followed the lead of his fellow classmates, hand shaking as he gripped the trigger and aimed. This was wrong, this was wrong. Wasn't it?

The blue-haired pigtailed kid in the class—Nagisa, was it?—gave the signal, "Shoot!"

And so, they shot.
