Introduction and the Arrival of Korosensei
A powerful alien arrives on Earth, threatening its destruction. The military attempts to neutralize the threat but fails miserably. The alien, resembling an octopus-like creature, becomes a high school teacher for Class 3E, a group of underperforming students. The Japanese government tasks Class 3E with assassinating the alien, now their teacher, before graduation to prevent Earth's destruction.
Class 3E and Their Mission
Class 3E consists of students with the lowest grades in Kunugigaoka School and are isolated in an old building as punishment. They discover their new teacher is the alien who destroyed part of the moon and plans to destroy Earth. Tadami Karasuma from the Ministry of Defense informs them of their mission to assassinate the teacher, and introduces special weapons effective against the alien but harmless to humans. The reward for assassinating the monster is 10 billion yen.
Training and First Assassination Attempt
Tadami Karasuma and Irina Jelavić are hired to train and assist the students. Nagisa Shiota attempts to assassinate Korosensei (as the students name him) with a grenade filled with special bullets, but Korosensei survives by shedding his skin. Angered by the risk to Nagisa's life, Korosensei threatens the families of the students involved, emphasizing his promise not to harm the students directly.
New Transfer Students: Karma and Ritsu
Karma Akabane, a violent student suspended from Class A, joins Class 3E. He attempts to assassinate Korosensei using anti-teacher material but fails. Korosensei teaches him a lesson about underestimating his opponent. Later, a new student, Ritsu, an AI robot, arrives with the goal of assassinating Korosensei, but is reprogrammed to work with the class as a team.
Itona Horibe and Shiro's Challenge
Itona Horibe, accompanied by his guardian Shiro, transfers to Class 3E and challenges Korosensei to a battle. Itona possesses tentacles similar to Korosensei, but Korosensei defeats him using his skills and the special rubber knife. After the fight, Korosensei reveals he became Class 3E's teacher to fulfill a promise.
Assassination Training Camp and Takaoka's Arrival
Korosensei organizes an assassination training camp to improve the students' skills. A new coach, Takaoka, arrives, but his violent training methods are opposed by Karasuma. Takaoka challenges Karasuma's best student to a fight, and Nagisa is chosen.
Nagisa vs. Takaoka
Nagisa defeats Takaoka using his hidden talent for assassination, forcing Takaoka to leave the school.
Poisons and Tentacle Destruction
Okuda creates poisons for Korosensei, who uses them to demonstrate his abilities. Korosensei then motivates the students to improve their academic performance by offering to let the top students destroy one of his tentacles, decreasing his speed and increasing their chances of assassinating him.
Academic Experiences and Exam Results
Korosensei takes his top students to various locations around the world to provide them with hands-on learning experiences. After the exams, Nakamura, Okuda, and Karma earn the right to destroy one of Korosensei's tentacles each.
Final Exam and Initial Assassination Plan
The students prepare to execute their plan to assassinate Korosensei during the final exams. They reflect on their feelings towards their teacher, acknowledging their affection for him despite their mission.
The Absolute Defense and Takaoka's Revenge
The students' initial assassination plan fails as Korosensei activates his "absolute defense," encasing himself in an impenetrable crystal. Takaoka returns, seeking revenge, and infects some students with a virus, demanding Nagisa hand over Korosensei in exchange for the antidote.
Karma and Nagisa's Stand and Itona's Redemption
Karma and Nagisa work together to stop Itona, who is helping Takaoka. They use their knowledge of Itona's weakness to defeat him. Itona is invited to join Class 3E.
The Final Confrontation and Korosensei's Fate
Nagisa confronts Takaoka, who plans to trap Korosensei. The students work together to trap Takaoka and his men. Military helicopters arrive to take Korosensei and the students to a base for a final attempt to destroy the alien. Korosensei gives a farewell speech to his students.
The "Destruction" and the Reunion
The military executes their plan, and everyone believes Korosensei has been destroyed. However, Korosensei reappears, revealing he survived. The students are relieved and return to their school routine.
