One day, a massive explosion suddenly vaporizes 70% of the moon. Following that incident, a mysiterious creature claims credit for the distruction of the moon and promises to do the same to Earth in March of the following Year. Even more peculiarly, it becomes the teacher of class 3-E (where misfit students end up) of Kunugigaoka Junior High School.
The creature possesses power beyond human understanding and proves impervious to military attacks. The leaders of every nation entrust the creature’s assassination to the students of class 3-E.
The supposedly slow learners of the class are now in an”assassination classroom.”Through new experiences, they forge friendship and gain confidence in themselves. As the second semester begins, the students feel the pressure of a literal deadline.
Will the mission to assassinate the teacher succeed by graduation!?
