Assassination Classroom

A creature has blown away part of the moon, and it says the Earth is next unless someone kills it before March. It also wants a job as homeroom teacher of Class E at Kunugigaoka High School, so the students, Nagisa Shiota (Ryosuke Yamada) and Karuma Akabane (Masaki Suda) among them, are handed the task. Eiichiro Hasumi sets the countdown ticking in the classroom, with a whole planet's survival resting on one class.
