His name, "Koro-sensei" is a combination of the words 殺せない (korosenai) which means “Unkillable" and the word 先生 (sensei), which means teacher or master. This nickname was given to him by Kaede Kayano.

History

He was born in one of the most vile and corrupt neighborhoods of an unknown country, in an environment where he could only trust himself. Through these difficulties, he decided to be an assassin, becoming the best assassin, known as Shinigami (死神 God of Death). With his talent he left a trail of death wherever he went.

All this began to change after murdering a rich businessman. This man's son witnessed it and, in love with the beauty of the murder, asked the Shinigami to train him as his apprentice. He taught him everything he knew, and after several successful jobs, the apprentice ended up betraying his teacher and taking the title of Shinigami.

After being betrayed, the Shinigami was captured and locked up in a research laboratory run by Kotaro Yanagisawa (Shiro), whose objective was to create antimatter within the cells of organisms and living beings.

In this research laboratory he met Aguri Yukimura, a professor who was at the time in an abusive arranged marriage to Kotaro Yanagisawa. As the tests continued, the Shinigami began to have greater trust with her, becoming interested in her work as a teacher and learning during this time what compassion was from her.

However, a problem arose when Yanagisawa and his researchers began to question what would happen to Koro-sensei's antimatter cells when he died. To answer this question, Yanagisawa and his team set up a small automated laboratory on the moon to safely test the possibility of what would happen if a subject with Koro-sensei's antimatter cells were to die (in this case, a little rat). when the rat died.
