Assassination Classroom ran for two seasons and 47 episodes, and it built one of the strangest premises in modern anime out of a simple joke: the deadliest thing in the room is also the best teacher in the building.
The series aired on Fuji TV and Iwate Menkoi Television from January 10, 2015 to July 1, 2016, adapted by Lerche from Yusei Matsui’s manga. It is classified as Animation, Comedy, Action & Adventure, and Sci-Fi & Fantasy, which is a fair description of a show that swings from slapstick to genuine dread inside a single episode.

Class 3-E and the ¥10 Billion Contract
The setup is laid out fast. Seventy percent of the Moon is obliterated, left permanently crescent-shaped. A yellow tentacled creature claims responsibility, and world governments cannot kill him — accelerated regeneration, visual cloning, near-impenetrable skin, and flight at Mach 20 make sure of that.
He gives humanity one year before he destroys the Earth. The agreement that follows puts him in a classroom at Kunugigaoka Junior High School, teaching Class 3-E, the students the school has deliberately disadvantaged over low grades and rule-breaking. Each student gets government-made weapons that can kill him. He is forbidden from harming them. The Japanese government promises ¥10 billion to whoever kills him.
Koro-sensei, as the class names him, teaches regular subjects and assassination technique in the same breath. Jun Fukuyama voices him, with Mai Fuchigami as Nagisa Shiota, Nobuhiko Okamoto as Karma Akabane, and Aya Suzaki as Kaede Kayano heading a deep supporting cast.
Why the Misfit Class Works
The premise should collapse under its own weight. It does not, because the show takes the teaching seriously. Koro-sensei improves his students’ grades, their individual skills, and their prospects, and the series never treats that as a gag to be undone.
That is the tension the whole run rests on. The kids have a real contract, real weapons, and a real deadline, and the creature they are meant to kill is the first adult who has ever been on their side. The manga ran in Weekly Shōnen Jump from July 2012 to March 2016 and was collected in twenty-one tankōbon volumes. By October 2023 it had over 27 million copies in circulation.
The franchise did not stop at the page. A Brain’s Base OVA screened at the Jump Super Anime Tour in late 2013. A live-action film arrived in March 2015, with Assassination Classroom: Graduation following in March 2016. Viz Media licensed the manga for North America; Crunchyroll, formerly Funimation, licensed the anime; Madman Entertainment handled digital distribution in Australia and New Zealand.

Key facts

The 8.4 is earned. What holds Assassination Classroom above its own gimmick is restraint — it never lets the assassination plot swallow the classroom, and it never lets the classroom soften the deadline. The countdown stays real, and so does the affection. That balance is harder than Mach 20, and the show keeps it for 47 episodes.
