### Koro-sensei

Voiced by: Jun Fukuyama (TV anime), Masaya Onosaka (vomic), Tomokazu Seki (event anime & J-Stars Victory VS), Kazunari Ninomiya (live-action) (Japanese); Sonny Strait (English)
Koro-sensei (殺せんせー, Koro-sensē) is the main protagonist and anti-villain of the series. He is a yellow octopus-like creature who is the teacher of Class 3-E of Kunugigaoka Junior High School. Koro-sensei is initially thought to be the perpetrator of the destruction of the Moon, which has rendered it permanently in a crescent shape; this is later revealed to be false, as the true culprit was a mouse implanted with his cells that had been sent to the moon as part of an experiment. Despite not having the intention to get killed, he offered to governments all over the world a chance to kill him under the condition that he is allowed to be the homeroom teacher of Class 3-E until the end of the year, when he will destroy the Earth by self-explosion unless he is killed. He is dedicated to his task as a teacher and imparting his knowledge of assassination to the students, despite knowing full well that he is their target. However, he is able to connect with each student individually, which is why all of his students respect him, despite knowing that he will destroy the planet in a year. His skin color changes depending on his mood, as well being able to move at a maximum speed of Mach 20 (24,500 km/h), which allows him to travel across the world in a short amount of time and makes him a hard target to hit. He is also intelligent to the point that he could teach almost every subject to all of his students single-handedly. He does however have a number of weaknesses, mainly to special rubber knives and BB pellets specifically designed to work against his body.
While he is initially believed to be an alien, he later reveals that he was once a legendary human assassin who was the original Reaper. After being betrayed by his apprentice (the Reaper seen throughout the series), he was captured and sent to a facility where a series of experiments were performed on him and transforms his body which causes him to mutate into an octopus. Koro-sensei was born in the slums of an unknown third world country, where he soon learned he had a natural talent for killing and never bothered using his empathy. He became an assassin, murdering anyone for the right price, even world leaders and the heads of entire militaries. However, after being captured and used as a guinea pig (although he can escape at any time, he chooses to stay to develop superpowers, subtly guiding the experiments so that he can profit from them), he begins to learn how to use compassion and empathy from a female intern with whom he becomes close. His decision to become a teacher involves his promise to the intern who thought that he was suitable to become one, later revealed to be Class 3-E's former teacher, Aguri Yukimura, who was selected to be his observer during the experiments performed on him and he had fallen in love with. After finding out Yanagisawa intended to dispose of him and he'll die in one year, he went on a rampage slaughtering nearly everyone in the facility except for Aguri and Yanagisawa (whom he blinded in one eye), having decided he didn't care about taking down the world with him. While he was stopped by Aguri, she was mortally wounded by one trap aimed at him, which lead him to become the teacher of class 3-E as it was Aguri's dying wish. According to Koro-sensei, his lifespan will be over by the end of the school year in March, and if he is not killed by then, the whole planet will perish with him due to the explosive release of the anti-matter in his body that was generated by the experiments performed on him. After a vicious clash with Kōtarō Yanagisawa, the scientist responsible for his current condition, and his former apprentice, the second 'God of Death', and using all of his energy left to save Kayano who was mortally injured during the confrontation, an exhausted Koro-sensei bids farewell to his students and finally allows them to kill him, with Nagisa ultimately doing so by stabbing him in the heart. After being assassinated, his body disintegrates into multiple floating orbs of light while his clothes are left behind.
Koro-sensei's name is a pun on the words korosenai (殺せない, lit. unkillable) and sensei (先生, lit. teacher).
Koro-sensei appears as a playable character in the video game J-Stars Victory VS.

### Nagisa Shiota

    Voiced by: Nozomi Yamamoto (vomic), Nao Tōyama (event anime), Mai Fuchigami (TV anime) (Japanese); Lindsay Seidel (English)
    Actor portrayal: Ryosuke Yamada
Nagisa Shiota (潮田 渚, Shiota Nagisa) is the main human protagonist of the series. He is one of the students in Class 3-E and the series' narrator. Nagisa is seen as one of the weakest students in the class due to his small stature and mediocre physical abilities that are comparable to some of the girls in the class. However, he is actually the most talented to become an assassin out of all the students, something that is acknowledged by Koro-sensei and Karasuma. He is able to draw closer while hiding his bloodlust to make a surprise attack and is able to make his opponents falter through his bloodlust alone. Nagisa usually writes down Koro-sensei's weaknesses, which at first seem minor (since they do not look like major weaknesses). However, some of them are eventually revealed to be useful as the students are almost able to kill Koro-sensei because of one of these weaknesses. Outwardly friendly and polite to his friends and everyone, he hides a somewhat darker side of him as an assassin that is not noticeable during daily life and is only revealed during training and assassination time. When engaged in battle, Nagisa becomes a brutal assassin who would throw away his life if it meant killing his target. According to Karasuma, whenever Nagisa unleashes his killing intent, he is not training and truly goes for a kill.
At home, Nagisa lives with his chronically absent father and abusive mother. His mother tries to live vicariously through him by making him follow her exact life plan for him, because she experienced a lot of failure in life and was also never allowed to look like a "pretty girl" by her parents. This causes her to constantly tell him she wishes he was born a girl and make him grow his hair long, which she only lets him tie up because if he unties, he still looks like a girl. His mother is also the foundation for his assassination talents, because whenever he tries to defy her when she is in what he perceives as a "gloomy" moment, she grabs and screams at him, so he learned to tell the difference between her "cheerful" and "gloomy" moments, in order to prevent some of her abuse.
Nagisa realizes that this is similar to the "Wavelengths of Consciousness" that the "God of Death", the world's best assassin, talks about. After this realization, he tells Koro-sensei he has the talent to be an assassin in a career planning meeting. His home life improves and his desire to be an assassin wanes after he saves his mother from an assassin, which in turn gave him time to realize his talents can be used to save people and she realized that she cannot hold onto him forever. When the time comes for Class 3-E to finally end Koro-sensei's life, Nagisa offers to deal the killing blow, which he regrettably does. During the graduation ceremony, Nagisa learns, much to his joy, that before his death, Koro-sensei talked with his father as well and helped him reconcile with his mother. During his time with Koro-sensei, Nagisa eventually realizes that he wants to be a teacher like him.
After, completing his studies, he becomes an intern at Gokuraka Private High School assigned to a dysfunctional class full of male delinquents and gang members, much to his chagrin. Nevertheless, he sets to work teaching and rehabilitating delinquent students while intimidating them into compliance with his bloodlust. In addition, Kaede implies that he will begin teaching at the old Class 3-E building in the future. He is also shown to have trimmed his long hair, although he sadly notes that he has not grown significantly taller at all since then. When Sumire Hara asks Kayano how things are between her and Nagisa, she bashfully replies that he is focused on his career at the moment.

### Kaede Kayano / Akari Yukimura

    Voiced by: Yō Taichi (vomic), Ayana Taketatsu (event anime), Aya Suzaki (TV anime) (Japanese); Monica Rial (English)
    Actor portrayal: Maika Yamamoto
Kaede Kayano / Akari Yukimura (茅野 カエデ / 雪村 あかり, Kayano Kaede / Yukimura Akari) is one of Nagisa's classmates and close friends, being the one who is mostly seen with him. She has an apparent affinity for pudding, once attempting to assassinate Koro-sensei with a giant pudding with explosives inside. She experiences a slight inferiority complex when it comes to sex appeal, especially her bust size, as she usually gets flustered towards girls with large breasts. Kaede is the smallest student in Class 3-E and is even shorter than Nagisa and Manami. She is also the student who comes up with Koro-sensei's name.
At the start of winter, she reveals her true identity to be professional method actress Akari Yukimura, the younger sister of Aguri Yukimura, the former Class 3-E teacher. Believing Koro-sensei to be her sister's killer, she stole and implanted tentacles from Shiro's facility onto the back of her neck and changed her identity in order to infiltrate Class 3-E, using her acting skills to hide her extensive blood lust from everyone until she was ready to make her move. However, using her tentacles in battle puts her life at risk, just like what happened with Itona, and before she dies, Koro-sensei manages to remove them from her body once Nagisa calms her down with a French kiss, shocking her to the point of passing out. It is also revealed that the time she spent with Koro-sensei and Class 3-E made her urge for vengeance falter over time and made her believe that there was more to Koro-sensei's past than what she had assumed. She then spends the winter break recovering at a hospital, and upon returning, decides to hide her newfound feelings for Nagisa in order to not give him trouble during their mission to assassinate Koro-sensei. During Koro-sensei's battle with Yanagisawa and the second God of Death, Kayano attempts to intervene, making use of the kinetic vision she obtained during the time she implanted the tentacles in her body, but is mortally wounded by the enemy, and to save her life, Koro-sensei performs an intricate surgery to restore her body up to the cellular level in order to save her life, a procedure he developed to ensure that the tragedy that happened with her sister would not be repeated, but exhausting himself in the process. After Koro-sensei's death, she resumes her acting career, becoming even more famous than before. When Sumire Hara asks Kayano how things are between her and Nagisa, she bashfully replies that he is focused on his career at the moment.

### Karma Akabane

    Voiced by: Nobunaga Shimazaki (vomic), Nobuhiko Okamoto (event anime/TV anime) (Japanese); Austin Tindle (English)
    Actor portrayal: Masaki Suda
Karma Akabane (赤羽 業（カルマ）, Akabane Karuma) is one of Nagisa's friends from previous school years, and considered to be the strongest and smartest among the Class 3-E students. He is the first one to be able to inflict injuries on Koro-sensei during their first meeting. He was suspended from school prior to Koro-sensei's arrival by his class' homeroom teacher due to his extremely violent behavior. Unlike most students in the class that were relegated there due to their low grades, Karma is one of the school's most gifted students as he is the only one able to match Gakushū in terms of test results and grades, but developed a rebellious attitude due to his previous teacher's betrayal after he severely wounded a top third-year student while saving a bullied student from Class 3-E, as despite believing he has done the right thing, his teacher revealed that he was only siding with him due to his grades to increase his reputation and did not want to be held responsible for what happened. Karma then brutally beat the teacher, leading to his transfer to Class 3-E. Because of this experience, Karma originally distrusts Koro-sensei, but Karma begins to accept him after realizing Koro-sensei is unlike the other treacherous teachers at the school. He and Nagisa have a tense friendship, which slowly develops into a heated rivalry, culminating in a battle to decide whether they should kill Koro-sensei or not. After losing the battle, he grows closer to Nagisa and even begins addressing him without any honorifics. He is also one of two to tease Kaede about her feelings towards Nagisa together with Rio.
After graduation, he decides to enlist on a government test with the intent of carving his own territory in politics.

## Antagonists
### Gakuhō Asano (浅野 學峯, Asano Gakuhō)

    Voiced by: Hideo Ishikawa (vomic), Shō Hayami (TV anime), Chris Rager (English)
    Board Chairman of Kunugigaoka Junior High School and Gakushū Asano's father. Responsible for Class 3-E's current condition, he and his son share a tense competitive relationship with each other. Gakuhō's teaching skills are seemingly on par with Koro-sensei's, and he seems to know the latter's secret. He eventually takes over as the teacher of Class 3-A in order to prove their superiority over Class 3-E once and for all. Gakuhō becomes more and more desperate as finals near, and eventually uses a teaching method that induces the entire Class 3-A, with the exception of Gakushū, into a zombie-like trance that makes them sacrifice their own personal well-being for the sake of studying. These events lead Gakushū to conclude that his father is insane and must be stopped. Gakuhō eventually falls into full-blown madness after his teaching methods fail to allow Class 3-A to beat Class 3-E and several 3-A students begin to contemplate transferring to Class 3-E. It is later revealed that when he had just started the Kunugigaoka Cram School, he was a passionate, caring, and talented teacher like Koro-sensei, but changed his ideal educational system after a tragic incident where one of his first three students, an aspiring basketball player, committed suicide due to constant bullying. He believed that it was due to him not teaching his students to be strong. This belief, combined with his guilt and grief, led him to become cold and calculating, and he avenged his student by ruining the lives of the bullies by getting them addicted to gambling. After being defeated by Koro-sensei personally, he accepts defeat and has shown some changes in his personality, while still refusing to give up on his educational policy. He also reconciles with Gakushū after they both decide to sue each other and the two ultimately spend some time bonding over the filing of their individual suits and dreaming of the payouts they will get. He is apparently aware of Kayano's true identity as she was the student he demoted to Class 3-E for intentionally breaking one of his possessions when she first transferred to Kunugigaoka. After Koro-sensei's death, the Class 3-E system is abolished and Gakuhō resigns from his position on the government's orders after the public found out about his draconian teaching methods. While he is packing up his office, however, he is visited by the remaining two students from his very first class, and begins catching up with them over a bottle of wine.

    Voiced by: Ryōta Takeuchi (TV anime), Mitsuaki Madono (Yanagisawa) (Japanese); J. Michael Tatum (English)
    Actor portrayal: Hiroki Narimiya
    A mysterious scientist who cloaks himself in anti-sensei material, he first appears as Itona's guardian and tutor, bestowing him with the tentacles on his head and providing him the medication needed to treat it. After several failed attempts however, he abandons Itona, soon taking an interest in Kaede's potential. Once Kaede fails as well, he reveals himself as Kōtarō Yanagisawa, the lead scientist who performed the experiments that transformed the God of Death into Koro-sensei and destroyed the Moon due to experimenting with a rat, thus making him the primary antagonist of the series. He also was Aguri's fiancé, and always mistreated her due to her low birth in comparison to his wealthy and well-connected family, and always saw her as only a tool. He holds a grudge against Koro-sensei, who completely shattered his pride upon taking control of the experiment and winning Aguri's favor, along with taking one of his eyes and seeks to kill Koro-sensei at any cost, but not before making him suffer by killing all his students first. He later returns after taking the second God of Death under his guard and modifying his body for them to enact revenge of Koro-sensei together in the final hour of the deadline before his explosion. Yanagisawa's body ends up disintegrated when he is blown away by a beam fired by Koro-sensei against the Second God of Death and comes in contact with an anti-tentacle barrier, leaving him in a semi-vegetative state, that has to be taken care of by other people, while his anti-matter research was cancelled by the government.

### Akira Takaoka (鷹岡 明, Takaoka Akira)

    Voiced by: Kenta Miyake (TV anime) (Japanese); Justin Cook (English)
    Actor portrayal: Masanobu Takashima
    A soldier who trained alongside Karasuma and was jealous of his abilities. He is sent to Class 3-E in order to take over their assassination training, but is forced to leave after being defeated by Nagisa, because of how sadistic his training was. He later returns, more insane than ever and he scarred his own face, he was laughed at by his peers after his defeat by Nagisa. During Class 3-E's field trip to Okinawa where he poisons more than half the class, with the only cure in his possession, he orders Nagisa and Kayano to bring Koro-sensei to him at his hotel room. Instead, Nagisa, Karasuma, and the remaining healthy students infiltrate his hotel and defeat his hired assassins, leading to a confrontation on the hotel roof. He then challenges Nagisa to a one on one fight to exact revenge for his earlier defeat, blowing up the case containing the cure to throw Nagisa into despair. However, after sustaining a beating at Takaoka's hands, Nagisa manages to stun him with Lovro's secret surefire assassination technique. Takaoka's worst fear is realized when Nagisa gives him the same innocent smile he had worn before surprising and defeating Takaoka the first time, before knocking him out with a stun baton. Takaoka stated that Nagisa's innocent smile will haunt him in his nightmares for the rest of his life. It is then revealed that the cure was unnecessary to begin with, as Takaoka's hired assassins had supplied him with a non-lethal poison, having privately agreed beforehand not to follow their employer's murderous plans. Takaoka is then taken arrested by the military, but he was later released from custody and began worshiping Nagisa as a goddess.

### The Reaper (死神, Shinigami)

    Voiced by: Nobunaga Shimazaki (Japanese); Ian Sinclair, Justin Briner (younger) (English)
    The number one assassin in the world, who starts to hunt down other assassins and eventually targets Class 3-E and Koro-sensei. He initially appears as a harmless florist, but his true form is hidden behind killing intent so thick that he appears to be shrouded in darkness, leaving his true appearance a mystery. In actuality, he peeled the skin from his face so as to become a master of disguise and has heavily modified his own body to become an efficient killer, such as implanting a small caliber gun in his index finger. He eventually convinces Irina to join him and kidnaps Class 3-E to draw out Koro-sensei, but is thwarted by Taiga and Sōsuke's skill with paint and cameras, before being betrayed by Irina and defeated by Karasuma in a fistfight before being detained and put under Yanagisawa's care. He is eventually revealed to be the second God of Death, the original being Koro-sensei, his former master, whom he betrayed upon believing that he had learned all he could from him and also being resentful of Koro-sensei not looking at him as a person. Initially he looked up to him and even to his death, wished to be acknowledged by him and to be just like him. Unfortunately, Koro-sensei only saw him as a tool since he had yet to learn compassion and empathy. Disillusioned, he took the title of God of Death after he betrayed Koro-sensei by letting him be captured by security guards after an assassination job. Since his confinement he went under Yanagisawa's experiments to prepare him for a final confrontation with Koro-sensei in order for both to enact their revenge on him, after the scientist revealed to him that his former mentor and the teacher of Class 3-E are the one and the same. Having a much more imposing and terrifying figure than his predecessor, the enhanced Second God of Death possesses many more tentacles than Koro-sensei and is capable of moving twice as fast than him. However, even with such improvements, he ends up being killed by Koro-sensei who blasts him with the a beam powered with his emotions, stabs him in the heart and throwing him against an anti-sensei barrier disintegrating him. Before Koro-sensei finished him off, he apologizes to his former student for not guiding him properly during their time as master and pupil before promising to start over if they meet again in the afterlife.

Conventionally, it is composed of twenty eight students who could not either compete with the school's standard level of study, nor comply with its overly rigid code of discipline, among others who were subjected to some form of unfair punishment. Obligated to attend class in a run down school building, set in a mountain far from the rest of the school's premises, the students of Class 3-E are largely discriminated against by the rest of their peers.
