Assassination Classroom (暗殺教室) is a Japanese manga series written and illustrated by Yusei Matsui. The series follows the daily life of an extremely powerful octopus-like being working as a junior high homeroom teacher, and his students dedicated to the task of assassinating him to prevent Earth from being destroyed. The students are considered "misfits" in their school and are taught in a separate building; the class he teaches is called 3-E. It was serialized in Shueisha's manga magazine Weekly Shōnen Jump from July 2012 to March 2016, with its chapters collected in twenty-one volumes.

In North America, the manga has been licensed for English language release by Viz Media. The anime series has been licensed by Crunchyroll, formerly known as Funimation.

An original video animation (OVA) adaptation produced by Brain's Base was screened at the Jump Super Anime Tour from October to November 2013. This was followed by an anime television adaptation by Lerche, which aired on Fuji Television, BS Fuji and other stations from January 2015 to June 2016. A live action film adaptation was released in March 2015, and a sequel, titled Assassination Classroom: Graduation

Plot

Earth is left in disarray when all of a sudden, 70% of the Moon is obliterated, leaving it permanently in the shape of a crescent. Not long after, a yellow tentacled creature appears to claim responsibility for the phenomenon. He soon proves to be unable to be killed by the world governments due to his arsenal of superpowers including accelerated regeneration, visual cloning, near-impenetrable skin, and the ability to move and fly at Mach 20. The creature claims that within a year, he will destroy the planet next. However, he offers mankind a chance to avert this fate.

Per the resulting agreement, the creature becomes a teacher at Kunugigaoka Junior High School, his students being members of Class 3–E, a class that is intentionally disadvantaged academically due to low grades, inability to meet the school's strict rules and policies, and other forms of cruel and unusual punishment. Each of the students are granted the chance to kill the creature, whom they dub "Koro-sensei" (殺せんせー) before his imposed deadline of the end of the school year, and are granted specialized weapons developed by the government that can kill him; furthermore, Koro-sensei is forbidden from harming the students in any capacity. In addition to teaching them regular subjects, Koro-sensei also teaches them the ways of assassination so that they can kill him in the future. The Japanese government promises a reward of ¥10 billion to whoever among the students succeeds in killing Koro-sensei. However, this proves to be a virtually impossible task not only due to his superpowers and death anxiety, but because he is also the best teacher they could ask for, helping them to improve their grades, individual skills, and prospects for the future. As time goes on, the situation gets even more complicated as other assassins come after Koro-sensei's life, some coveting the reward, others for personal reasons. The students eventually learn the secrets involving him, the Moon's destruction, his ties with their previous homeroom teacher, and the true reason why he must be killed before the end of the school year.
