Koro sensei: good morning class take your guns out and try to shoot me while I call roll. The class: takes their guns out and try’s to shoot him Nagisa: thinks to himself (this is how it is now if he don’t kill him before the year is over he will blow up the earth but he is moving at mach 20! How can we kill him?) Karma: thinks to himself (say good bye teacher I will kill you!)
