殺せんせー
Koro-sensei is a yellow octopus-like creature who becomes the teacher of Class 3-E while his students try to assassinate him.
Overview
Koro-sensei is the yellow, tentacled teacher of Class 3-E in Assassination Classroom, Yusei Matsui's manga adapted by Lerche from 2015. After destroying most of the moon, he announces that he will destroy the Earth in a year and demands to teach the outcast class at Kunugigaoka Junior High, which is ordered to assassinate him for a ten-billion-yen bounty.
Capable of moving at Mach 20 and regenerating, he is nearly impossible to kill, yet he is a devoted, tirelessly attentive teacher who improves every student's grades and confidence. His former identity as the assassin known as the Reaper and his connection to Aguri Yukimura are revealed late in the story.
Koro-sensei's ridiculous face and heartfelt lessons made the series a beloved school drama disguised as a comedy. He is voiced by Jun Fukuyama in Japanese and Sonny Strait in English.
