Biography

Classroom teacher.

Korosensei (Japanese: 殺せんせー, Hepburn: Koro-sense) was a male human that lived on Earth in the modern day. Originally human, as a child he was born in the most vile and corrupt slims of an unknown country. During his early life, he lived in an environment where people easily betrayed one another leading to the child feeling that he could only ever trust himself. By adulthood, he decided to become an assassin with him going through many hardships till he became the master assassin known as the God of Death. During his career, he had left a large number of corpses in his wake which showcased his talents. Such was his representation that he became notorious for breaking through even the strictest of security teams in order to assassinate his target which he did without any problem. One of his missions involved the assassination of a wealthy businessman who was the father of a young boy. The child witnessed the death of his father and became enamored with the skill and beauty of the kill made by the assassin. He later went out to find the God of Death and requested that he be trained by him as an apprentice. The God of Death was eager for the assassination opportunities afforded by an apprentice and accepted where he began to train the boy. In time, he taught the young assassin everything he knew of the art of killing whilst instilling respect and fear in him along with letting the boy know of the difference in power between them. Together, the two worked well with them completing several missions that were a success. However, the apprentice turned on his master where he ensured that the God of Death was captured during an escape from a prison facility. The apprentice had abandoned his master to fuel his own ego and took his title by becoming the new God of Death. Meanwhile, the former title holder was captured and taken to a secret research laboratory that was run by Kotarō Yanagisawa. Yanagisawa had sought a test subject in his research to create large amounts of anti-matter by having it grown within human cells. Thus, the master assassin was chosen as the test subject for these excruciating experiments.

It was there that he met and befriended Aguri Yukimura, a teacher who was at the time in an arranged and abusive marriage to Yanagisawa. She was brought in to keep a closer eye on him as Yanagisawa considered her easily expendable if he attempted to break free and take her hostage. As the tests continued, the Reaper began to slowly bond with her and became fond of her as she worked on compiling exam questions for her class, and it was during this time he learned about the nature of compassion. One year after he had been imprisoned in the lab, Aguri got him a large tie as a present, since he would complain about his neck being cold and because he didn't know his actual birthday, she though their anniversary was as good a day as any. However, a problem arose when Yanagisawa and his researchers questioned what would happen to Korosensei's antimatter cells when he died. To answer this question, Yanagisawa and his team launched a small automated lab onto the moon to safely test the possibility of what happened if a subject with Korosensei's antimatter-infused cells were to die, in this case, a small lab rat. When the rat did die at the end of its lifespan, it caused a volatile reaction with the antimatter in its body. The antimatter created a chain reaction that turned 70% of the moon's matter into antimatter, which completely exploded. Upon seeing this, Yanagisawa was horrified at the results. His subordinates then began running calculations and discovered that the same thing will happen to the Reaper by March 13 of the following year. Earth would be destroyed the same way if left unchecked, prompting Yanagisawa to order his subordinates to start preparations to kill him. A mortified Aguri overhears this and decides to go speak to the Reaper and tell him their findings. However, when she does, he reveals that it does not bother him as he expected a death such as this from the start. Telling Aguri to leave, he finally unleashes his full power that he gained from the experiments to escape as a visibly fuming Yanagisawa watches from a nearby security camera. The Reaper then proceeded to rampage violently, killing off several guards, destroying the building, and in the process of it all damaging Yanagisawa's left eye.

However, during the escape, Aguri is mortally wounded when she landed in the line of fire of a special tripmine meant for him, to the latter's horror. He then laments that if he had not wasted his skills on killing, he would know how to save her. Her final wish to him was to teach the students of Class E, all while thinking of what a wonderful teacher he will be. Depressed but not broken, the Reaper vowed to help those children. He took the tie Aguri got him, left a note, left the facility for a nearby mountain, and then used various items on the mountain to create a new set of clothes to suit his new role as a teacher. Although not responsible for destroying seventy percent of the moon, he takes the blame and tells the world's leaders that he will destroy the Earth as well in March of the following year and requests to become the homeroom teacher for Kunugigaoka Junior High School's Class 3-E. The world leaders accept the deal, hoping it will give them a chance to assassinate him; however, they also added another condition: he would not harm the students. To avoid mass panic, the public existence of the creature was not to the world in order to prevent a mass panic.

As Korosensei starts the attendance, he asks Nagisa Shiota, who is on day duty, to issue command. Korosensei was ambushed by his students with automatic rifles, but he dodges the bullets while doing the attendance. Korosensei is pleased that there are no absentees, but he was also ashamed that nobody could hit him. He tells them that they should devise a plan together. The students complain that even if he were to get hit by the BB pellet bullets, he would just endure it. Korosensei demonstrates that those BB bullets, created specially in America for harming him, are harmless to the students and shoots his right feeler off. However, Korosensei regenerates his feeler back after a few seconds and warns them not to use them indoors except for killing him. He then tells them that they will kill him before graduation and decides to tidy the class up. Later, he questions Masayoshi Kimura of which one of his four tentacles is the weird one, which Kimura responds that the blue tentacle is the odd one and Korosensei is then pleased with his correct answer. He then catches a bullet with his chalk. He becomes red and punishes Rio Nakamura, saying that her assassination meddles with her study. When lunchtime starts, Korosensei decides to go to China while grading his student's tests. Korosensei later came back with a missile souvenir after having been ambushed by the self-defense in the Sea of Japan. Nagisa asks him if it was troublesome that he was targeted, but Korosensei tells him that he doesn't mind, and that it shows proof of his vast power. The class starts again and Korosensei decides to assign a poem and the one who is finished should bring it to him. Korosensei was asked by Kaede Kayano what name they should refer him as; Korosensei tells her that they can decide. Korosensei sees Nagisa walking up deliver the letter. He was suddenly struck by him, but he easily blocked it. However, Nagisa retaliates with a BB pellet grenade, much to Korosensei's surprise; but Korosensei uses his shed skin to protect himself and Nagisa, which he can only use once a month. After revealing his ability, he turns black with extreme anger and calls out the ringleaders of the BB pellet grenade. Korosensei then roams around town with his mach 20 speed and brought the nameplates from their houses. He tells the students: due to the agreement to not harm the students, if they try the same assassination method again, then he would annihilate anyone they know. He was questioned by Ryoma Terasaka of the degree of the assassination, and Korosensei corrects him by saying that it was excellent and praises Nagisa for keeping a natural body movement. However, Korosensei admonishes them of having no regard for Nagisa's life. He then advises them that they should use an assassination method that will make everyone happy and that they should use their hidden talents. After seeing a burn mark on a table, he remembers the incident from his past.

Overview

Personality and attributes

Korosensei.

In appearance, he was originally a male human with pale skin and short black hair that reached the nape of his neck. After his transformation, he became a humanoid yellow skinned octopus-like creature who stood 3-meter tall where he had a large bulbous head that had a large smile that never broke when he spoke and he had small beady eyes. Korosensei had multiple tentacles but used two primary ones as arms with each having two feelers that functioned like fingers whilst the remaining tentacles he used as legs to walk around on. Originally, he went by the name of Reaper (死神, Shinigami) that got taken by his student. After his transformation, he took the name of Korosensei (殺せんせー).

Due to his harsh upbringing, he had initially learnt that people betrayed one another easily leading to him believing that the only person he could trust was himself. Despite that, he did take on an apprentice but he instilled fear, respect and ensured his disciple knew of the power difference between them. Whilst he had kept a close eye on his apprentice, the master assassin was still surprised when his student had arranged for his capture.

He stated that he did not have a name that he could share and instead offered his students to name him. Kaede Kayano decided to use the word 'korosensai' (殺せない) that meant 'unkillable' and merged it with the word sensei (先生) which meant 'teacher' thus making 'Korosensei'.

Such was his anger that he stated that whilst he was bound by the terms of the agreement of not harming the students - he was not above harming their family, friends and loved ones should they cross a line.

Powers and abilities

Originally, Korosensei was a human being though one who came to be an incredibly skilled assassin.

He was capable of incredible speed and was said to be able to reach Mach 20 with no difficulty. This allowed him to rapidly respond to attacks with ease and fly to other destinations such as countries quickly. Korosensei's speed was such that he could make such journeys and return in a short span of time. An example was when during break at class he went for a meal in China and returned back to his students within a short span of time.

According to him, he was able to shed his skin that he did so once a year with this appearing as a mucous membrane that could be used to protect someone from explosions.
