ok so this is a Karmagisa fanfic. nagisa abused by his mom but way more phisically abused. and in this au koro sensei works with the government and only there class knows he exists he is an assassin and their class is practically usual they do regular school stuff. and karasuma is still a teacher. and they still learn assassin stuff. there might be missions they go on and there might not be, not sure. I'm probably not going to include most of the class mates there are way to many So just some of the main ones.
