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 was serialized on Shueisha's Weekly Shōnen Jump magazine from July 2012 to March 2016 and is licensed in English by Viz Media. The series follows the daily lives 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. As of February 2016, twenty-one tankōbon volumes have been released in Japan with a circulation of 20 million copies.[2]

A single original video animation adaptation by Brain's Base based on the series was screened at the Jump Super Anime Tour on October to November 2013. This was followed by an anime television adaptation by Lerche, which began airing on Fuji TV in January 2015. This adaptation has been licensed by Funimation for release in North America. The series was obtained by Madman Entertainment for digital distribution in Australia and New Zealand. A live action film adaptation was released on March 21, 2015, and a sequel, titled Assassination Classroom: Graduation, was released on March 25, 2016.


Earth is left in jeopardy after an immensely powerful organism suddenly appears and destroys 70% 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 he 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. 100 million USD) 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 pupils 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.
