Assassination Classroom

In Kunugigaoka Junior High School, Class 3-E is a class of misfits and outcasts. Their new teacher, Koro-sensei, is an octopus-like being who has destroyed 70% of the moon and threatens to do the same to Earth. The students are tasked with assassinating him before graduation, but as they train to kill their teacher, they learn valuable life lessons and grow as individuals.
