Kunugigaoka Junior High is a prestigious private school located in Tokyo, Japan. It is renowned for being one of the top schools in all of Tokyo and has a high rate of successful students. Class E, also known as the End class, every student that had bad scores or were troublemakers got transformed to that class. In the kunugigaoka school, all the students look down at the class E and act pretty prideful. So what could possibly happen when the prideful president of the student council, Gakushu Asano, the only son of the principal get transformed to the E class?

The question is, why would HE get transformed to the End class?

A powerful creature claims that within a year, Earth will be destroyed by him, but he offers mankind a chance by becoming a homeroom teacher where he teaches his students about how to kill him, also known as Koro-Sensei.

Since Gakushu knew how to work with weapons and was skilled in martial arts and close combat, he was given a chance to join the Class E in killing their teacher.

He stood there, holding his backpack and facing the students of the class E, standing next to the creature named as Koro-Sensei.

He had his arms folded, putting on a stoic and prideful face, he wasn't going to end up getting friendly with his "Rivals" anyway.
