Ajin : Demi-Human Anime Synopsis

Mysterious immortal humans known as “Ajin” first appeared in Africa 17 years ago. When they were discovered, they were labelled as a threat to humanity because they could use their powers for evil and could not be destroyed. Since then, whenever an Ajin is discovered in society, they must be arrested and taken into custody right away.
Kei Nagai, a high school student studying hard to become a doctor, knows very little about Ajin, having only seen them in the news on occasion. Students are taught that these creatures are not human, but Kei isn’t paying attention in class. As a result, his perilously limited understanding of the subject becomes completely irrelevant when he survives an accident that was supposed to kill him, signalling his rebirth as an Ajin and the beginning of his days of torment. However, as he finds himself alone and on the run from the entire world, Kei quickly realises that more of his species may be much closer than he believes.

Ajin : Demi-Human Anime Characters

Kei’s Group

Kei Nagai

Kei discovers he is an Ajin after he is killed in a car accident. To his peers, he appears to be a normal and carefree student, but in reality, he is emotionally detached from others and is frequently willing to jeopardise the lives of others in order to achieve his own goals. He is distinct from most Ajin in that he can generate an abnormally large amount of IBM (Invisible Black Matter, which is essential to an Ajin’s regeneration and ability to create “black ghosts”), allowing Kei to manifest more “black ghosts” than his Ajin peers. He is said to have manifested his Ajin-related abilities at a young age, according to Ikuya.


Kei’s close friend who assists him in eluding the police. He was later imprisoned for aiding Kei’s escape and later befriends Takeshi, another Ajin, allowing Kaito to escape.

Kō Nakano

Ko is an Ajin who works with Kei to put a stop to Sato’s plans to establish an Ajin-led government, which will result in the loss of many human lives. Unlike Kei, who is cold and indifferent to others, Ko values friendship and is willing to put others’ safety ahead of his own. He is also physically fitter than Kei, but lacks Kei’s intellectual capabilities, frequently relying on Kei for combat operations planning, with him acting as the operation’s “muscle.” Ko possesses the same rapid regenerative abilities as Ajin, but lacks the ability to manifest his own “black ghost.”

Ministry of Health, Labour and Welfare

Yū Tosaki

Yu is the director of Ajin Research for the Ministry of Health, Labor, and Welfare, and he has a comatose fiancée, Ai. Izumi Shimomura, an Ajin bodyguard, protects him. He agrees to let Kei work with him to stop Sato if Kei is allowed to live a normal life afterwards.

Izumi Shimomura / Yōko Tainaka

Izumi is a stoic and reserved Ajin who works at the Ministry of Health, Labour, and Welfare for Yu Tosaki. Yoko Tainaka is Izumi’s given name. She first discovered her Ajin abilities as Yoko in her adolescence, when she died defending herself from a rape attempt by an abusive stepfather. Yoko would flee from home, where she was eventually hired as a bodyguard under a special contract by Yu. The contract allowed Yoko to use the alias “Izumi Shinomura,” so “Yoko Tainaka” is legally deceased and “Izumi Shimomura” is a separate identity. Kuro is her affectionate name for her “black ghost.”


Yu’s Ministry junior, who was also assigned to supervise Yu. Sokabe was appointed as Yu’s successor after he decides to defy orders from the Minister of Health, Labour, and Welfare.


Satō (Satou) / Samuel T. Owen

Sato, the leader of the pro-Ajin movement, is a calm and collected individual who is well-known within the Ministry of Health, Labour, and Welfare as the most dangerous Ajin. He is also known as Hat due to his signature flat cap hat. Despite his outward appearance as a friendly old man who enjoys video games, he is a sinister, calculating tactician with combat experience as a former USMC special-operations soldier. Sat initially claims that he wants to protest the mistreatment of Ajins all over the world, but it is later revealed that he is using this claim as an excuse to gather an army of Ajin under his command in order to create an immortal army to rule Japan and simply for the sake of violence and destruction. In the latter half of the anime, he is frequently referred to as a “player,” as he is prone to using video game-inspired strategies to carry out assassinations of famous politicians in order to force negotiations with the government for Ajin rights. He enjoys using violence against anyone (human or Ajin) who tries to derail his plans, and he is especially irritated by provocation.

Kōji Tanaka

In Japan, he is the second Ajin to be discovered. Sato saves him from brutal experimentation and he joins Sat’s pro-Ajin movement against the Japanese government.

Masumi Okuyama

Masumi is one of the few Ajins who accept Sato’s invitation to use genocide to fight for the rights of Ajins. He is a skilled hacker who is well-versed in weaponry and machinery. In the anime, he eventually betrays Sato and seeks to defeat him by reaching out to Kei.

Takeshi Kotobuki 

A prisoner who escaped after hearing Sato’s announcement in order to protest for Ajins’ rights. Takeshi becomes Kaito’s partner after Kaito assists him when he is bullied by other inmates who want to know how he escaped from jail. His IBM is depicted as having wings, which he used to escape from prison. After he and Kai reconcile, he promises to let Kai use his IBM to escape prison for whatever reason he needs to help Kei. In the anime, Takeshi uses his IBM to transport himself and Kai to Eriko’s hospital in order to save both her and Kei from the riots that are taking place there.


Eriko Nagai

Kei’s sister, who appears to be suffering from a terminal illness and is hospitalised for the majority of the series.

Ikuya Ogura

He is a Japanese-American researcher who studied Ajins in the United States and is well-versed in them.
