Having already destroyed the moon, a mysterious visitor from outer space, named Koro-sensei, announces that he intends to do the same to Earth. But this alien – a cross between an emoticon and a giant yellow octopus – seems to like a challenge, and so offers the government a puzzling deal. He will train Class 3-E, the worst class in the prestigious Kunugigaoka Junior High School, to defeat him; but if they fail to take him out by graduation day, humankind will meet its fate. Based on the popular manga and TV series, this live action version of Assassination Classroom is a must-see!
