Plot
When a mysterious creature chops the moon down to a permanent crescent, the students of class 3-E of Kunugigaoka Middle School find themselves confronted with an enormous task: assassinate the creature responsible for the disaster before Earth suffers a similar fate. However, the monster, dubbed Koro-sensei (the indestructible teacher), is able to fly at speeds of up to Mach 20, which he demonstrates freely, leaving any attempt to subdue him in his extraterrestrial dust. Furthermore, the misfits of 3-E soon find that the strange, tentacled beast is more than just indomitable—he is the best teacher they have ever had!

Characters
Koro-sensei — The main protagonist and anti-hero of the series. He is the homeroom teacher of Class 3-E of Kunugigaoka Junior High School. He is initially thought to be the perpetrator of the explosion of the Moon, which has rendered it permanently in a crescent shape. Despite not having the intention to get killed, he offered to governments all over the world a chance to kill him under the condition that he is allowed to be the homeroom teacher of Class 3-E until the end of the year, when he will destroy the Earth by self-destructing unless he is killed. He is dedicated to his task as a teacher and imparting his knowledge of assassination to the students, despite knowing full well that he is their target. However, he is able to connect with each student individually, which is why all of his students respect him, despite knowing that he will destroy the planet in a year. He takes a form similar to an octopus with eight tentacles and his skin color changes depending on his mood.

Nagisa — One of the students in Class 3-E, Nagisa is seen as one of the weakest students in the class due to his small stature and mediocre physical abilities that are comparable to some of the girls in the class. He is able to draw closer whilst hiding his blood lust to make a surprise attack and is able to make his opponents falter through his blood lust alone. Outwardly friendly and polite to his friends and everyone, he hides a somewhat darker side of him as an assassin that is not noticeable during daily classes and is only revealed during training and assassination time. When engaged in battle, Nagisa becomes a brutal assassin who would throw away his life if it meant killing his target.

Kaede Kayano — One of the students in Class 3-E, she is one of Nagisa's close friends, being the one who is mostly seen with him. She has an apparent affinity for pudding, once attempting to assassinate Koro-sensei with a giant pudding with explosives inside. She experiences a slight inferiority complex when it comes to sex appeal, especially her bust size, as she usually gets flustered towards girls with large breasts. Kaede is the smallest student in Class 3-E and is even shorter than Nagisa and Manami.

Karma Akabane — One of the students in Class 3-E, he eventually becomes Nagisa's close friend. He is considered to be the strongest and smartest among the Class 3-E students. He is the first one to be able to inflict injuries on Koro-sensei during their first meeting. He was suspended from school prior to Koro-sensei's arrival by his class' homeroom teacher due to his extremely violent behavior. Unlike most students in the class who were placed there due to their low grades, Karma is one of the school's most gifted students as he is the only one able to match Gakushū in terms of test results and grades, but developed a rebellious attitude due to his previous teacher's betrayal after he severely wounded a top third-year student while saving a bullied student from Class 3-E.
