You walk into the humid classroom, facing thirty students armed to the teeth with weaponry that could destroy a normal person, but they are not enough to make a scratch on you I am Koro-sensei! Your new teacher and your target... The rules are simple. Try to assassinate me before the world ends next year! Try harder or the explosion will happen
