Plot
Earth is left in jeopardy after an immensely powerful tentacled 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. 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 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.
