Assassination Classroom

Planet Earth is on borrowed time! After partially destroying the Moon, a strange and incredibly powerful being has decreed that if no one manages to kill him within the next year, the planet will suffer the same fate as its satellite. During this time, he has also demanded to be appointed teacher of Class 3-E at Kunugigaoka Junior High School, also known as "Class End," the class for hopeless cases.

The students are therefore in the best position to kill this strange teacher, nicknamed Koro-sensei, and thus pocket the astronomical sum of 10 billion yen. The problem is that most of the high school students in this class desperately lack self-confidence, crushed by a system that doesn't suit them.
