What Season 1 of Assassination Classroom

Class 3-E at Kunugigaoka Junior High in Japan has a mission: kill Koro-sensei, a tentacled being who has destroyed part of the Moon and threatens to wipe out Earth within a year. If none of his students manage to do it before graduation, the planet will be destroyed. The government offers ten billion yen for his head. The students must combine their assassination attempts with lessons from a teacher who turns out to be an excellent one. Each episode focuses on a student, such as Karma, Nagisa, Sugino or Okuda, and on their conflict between wanting to kill him and starting to care for him. Teacher Irina Jelavic and government agents make the situation even more complicated.
