The teacher is called Sylvi, the swastika dude Arska and the main character doesn't have a name (aka I forgot it). The gun person is based on a human character me and my friend made up few years ago (Long live, TK!) but this one is anthro character and has a real gun instead of toy gun which shoots water. Unfortunately he gets a heart attack on this one.

Would it be nice if I did several comics of that dude and he would die in every one of them?

The comic Jack inspirated me to make up this ending. Here: http://www.pholph.com/strip.php?id=5&sid=363
