After destroying the moon, an inhuman nigh unkillable creature has decided to destroy the earth in less than a year. For some reason, he has decided to become a High School teacher and under no circumstances will harm his students. His students now have to kill their teacher before he destroys the planet.

 * Berserk Button: Koro-sensei goes to Brazil during the 2014 FIFA World Cup, and accidentally mentions the numbers 7 and 1 several times. The thing is, Brazil just lost the semifinal match of the cup in their home by a humiliating score of Brazil 1 x 7 Germany. The result is lot of pissed off brazilians.

 * Groin Attack: To put it in simple terms, Karasuma kicks the "Shinigami" in the groin.
 * Kryptonite Is Everywhere: To be fair, the threat that is Koro-sensei is a closely guarded secret and anyone other than world leaders let in on that secret is more likely than not supposed to kill him and has been supplied special weapons suitable solely for the task of killing him (in fact often these weapons are unsuitable for killing humans).

 * Playing Possum: Downplayed. In Chapter 104,.
