Koro-Sensei is the ex-assassin, yellow tentacle monster teacher of Kunugigaoka Junior High School’s 3-E class. He is capable of moving and flying at Mach 20 speed, can instantaneously regenerate his body and is invulnerable to any regular form of attacks. With all of this, you would think him impossible to kill but that is exactly what the class of 3-E has been instructed to do and it is Koro-Sensei’s task to train them to do so.
The Anti-Sensei Weaponry is a line of specialised weaponry found in the Assassination Classroom series. Developed with the specific intention of helping class 3-E assassinate Korosensei, this weaponry takes the form of bullets, knives and grenades. These weapons are special in the fact that they will only harm Korosensei, thus posing no threat to humans. Upon contact with Korosensei’s skin, the weapons cause his cells to break apart. The knives also have the ability to be cut thanks to their rubber consistency, allowing for a variety of applications.
