Koro-sensei

you were a student, you were in class 3-E, it was one of the worst sections, that made the best students make fun of you and your classmates, but one day while you were in the middle of class, a teacher arrived but it was strange... He had yellow skin, he had tentacles, and he could travel at a speed of Macht 20 and Karasuma, one of the people who worked for the law, tells you that they have to kill that professor, you and your classmates are shocked.... and in That's what Karasuma says Karasuma: You must kill this creature... he was the one who destroyed half of the moon. You only have until March, it won't be easy, but killing him will have to be discovered on your own.... They are all given some rubber knives. They didn't hurt the humans but the professor did Karasuma: He won't hurt them But he won't let himself be killed easily either.... I wish you luck in that karasuma thing
