Assassination Classroom (2015)

The world changed fundamentally on the day that 70% of the moon is destroyed in a dramatic explosion. An alien creature arrives claiming credit for the attack and promising that he will destroy the world in a year. But that claim comes with some interesting conditions. It's taken up residence as a high school home room teacher, and it claims that it's willing to teach its students how to kill it. If they can learn everything they need to and maintain their resolve, they could stop the imminent apocalypse. But what is the motive of the strange alien that's testing them?
