Assassination Classroom

The octopus-like professor Koro-sensei has promised to destroy the Earth by March of the following year after destroying the moon and endangering humanity.

The students at the prestigious Kunugigaoka Middle School have discovered that killing him is very difficult when considering their purpose.

Nagisa Shiota and the other students in Class 3-E have to discover the weaknesses of Koro-sensei via trial and error—and quickly, as the world’s very survival relies on it.
