An Assassin for a teacher
Nagisa didn't always know what he wanted to do, but once he did he worked hard for it. He was going to be a teacher, and like Koro-Sensei before him, teach kids to learn even in the strangest or worst of enviroments.
It just so happens that he got his own version of E-class. Except they don't care about getting good grades or even care about other people, unlike E-class, though after his first day and a challange to his students, Nagisa is waiting to see how his very own E-class will turn out. Oh, and he just so happens to get a vist from karma as well, I'll you decided what I mean by that.
(So first off, there aren't enough Nagisa as a teacher fanfictions to begin with and also my best friend Maya requested that if I had no idea what to write then to write this, so here we are.)
[I do not own any of the characters, ideas or themes, I only add the names of the students from Nagisa's class as I have not watched the 365 days movie yet so I don't know if they actually are given names or not.]
