Assassination Classroom (Japanese: 暗殺教室, Hepburn: Ansatsu Kyōshitsu) is a Japanese science fiction comedy manga series written and illustrated by Yūsei 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 Weekly Shōnen Jump magazine from July 2012 to March 2016, with its chapters collected in twenty-one tankōbon volumes.

An original video animation (OVA) adaptation 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 TV from January 2015 to June 2016. A live action film adaptation was released in March 2015, and a sequel, titled Assassination Classroom: Graduation, was released in March 2016.

In North America, the manga has been licensed for English language release by Viz Media. The anime series has been licensed by Funimation. The series was obtained by Madman Entertainment for digital distribution in Australia and New Zealand.

As of September 2016, the Assassination Classroom manga had over 25 million copies in circulation.


Earth is left in jeopardy after an immensely powerful tentacled creature suddenly appears and destroys 75% of the moon, leaving it permanently in the shape of a crescent. The organism claims that within a year he will destroy the planet next, but offers mankind a chance to avert this fate. In class 3-E, the End Class of Kunugigaoka Junior High School, he starts working as a homeroom teacher where he teaches his students regular subjects, as well as the ways of assassination. The Japanese government promises a reward of ¥10 billion (i.e. US$100 million) to whoever among the students succeeds in killing the organism, whom they have named "Koro-sensei" (殺せんせー, Korosensē, a pun on korosenai (殺せない, unkillable) and sensei (先生, teacher)). However, this proves to be a highly unachievable task, as not only does he have several superpowers at his disposal, including accelerated regeneration, visual cloning, an invincible form, and the ability to move and fly at Mach 20, but he is also the best teacher they could ask for, helping them to improve their grades, individual skills, and prospects for the future.

As the series 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, and his ties with their previous homeroom teacher including the true reason why he must be killed before the end of the school year. The series is narrated by Nagisa Shiota, one of the students in the class whose main strategy in killing Koro-sensei is making a list of all his weaknesses over time. At first, Nagisa appears to be one of the weaker members of Class 3-E, but he later emerges as one of the most skillful assassins in the class.
