One day, the moon suddenly burst, and roughly 70% of it was annihilated.

The culprit is a super being that had stated he’d destroy the Earth come the following March, but for some reason, he appeared in a middle school classroom. What’s more is that he’s acting as the teacher there.

With powers that go beyond human understanding, he cannot even be brought down by military forces. So it is left up to the students of Class-E, year 3 at Kunugigaoka Middle School to assassinate him.

And so, with a very strange teacher who appeared out of the blue, the first term’s classes begin!

Koro-sensei

Voice Actor: Jun Fukuyama

He is a super being who was named “Koro-sensei” by the students, and is derived from the fact that he’s a teacher who can’t be killed. With the ability to move as fast as Mach 20, and several multi-purpose tentacles, most attacks are rendered useless against him. It remains unclear why he is in charge of Class-E, but his skills at teaching are impressive.

Nagisa Shiota

Voice Actor: Mai Fuchigami

As his specialty is gathering intel, he is currently investigating Koro-sensei’s weaknesses. He has a calm and gentle attitude. That being said, he is actually quite proficient at assassination.

Karma Akabane

Voice Actor: Nobuhiko Okamoto

His grades are immaculate, but his attitude could be better. He reacts incredibly quickly, and is quite the prankster. He’s the first one in the class to have dealt any damage to Koro-sensei.

Tadaomi Karasuma

Voice Actor: Tomokazu Sugita

He’s a member of the Ministry of Defense. As Class-E’s PE instructor, he assists in honing the students’ assassination technique.
