One day, without warning, a member of the Ministry of Defense and a mysterious creature with a grotesque appearance arrived before Class 3-E of Kunugigaoka Junior High School, a class made up of students with poor academic records and bad behavior at the prestigious school.
The dangerous creature, capable of flying through the sky at Mach 20 and having already destroyed seventy percent of the moon, leaving it permanently in a crescent shape, declared that "if I am not killed by next March, I will destroy the Earth," and requested to become the homeroom teacher of Kunugigaoka Junior High School Class 3-E.
In order to assassinate the creature, the government turns to the White Room's greatest masterpiece, Ayanokōji Kiyotaka, and asks him to carry out the assassination. Will Ayanokōji be able to take down the target?
