Ajin: Demi-Human (Japanese: 亜人 Hepburn: Ajin) is a Japanese manga series written and illustrated by Gamon Sakurai. It was adapted into an 3D animated film trilogy by Polygon Pictures between November 2015 and September 2016. An anime television series adaptation also by Polygon Pictures aired between January and April 2016, with a second season premiering on October 8, 2016. A live-action film adaptation was released on September 30, 2017.
Ajin: Demi-human presents the story of a student named Kei Nagai (永井 圭 Nagai Kei), who discovers he is an "Ajin" when he is fatally wounded in a traffic accident. In the world of Ajin, a small number of humans (termed "Ajin") possess extreme regenerative abilities that trigger upon death or mortal injury, allowing them to completely recover from their wounds in a matter of seconds to such an exceptional extent that not only can missing limbs be restored, but Ajin can fully regenerate after being turned into literal meat patties. Additionally, Ajin can create "black ghosts", which are highly dangerous combat-oriented entities that are invisible to normal humans and only visible to other Ajin. "Black ghosts" are resistant to physical injury and exhibit extraordinary physical strength, and have razor-sharp teeth and claws. Different "black ghosts" have varying degrees of intelligence. For example, most "black ghosts" are completely reliant on their Ajin for directions, and others, such as that of Kei's, are more independent and likely to engage in self-initiated actions.
Consequently, Ajin are considered dangerous and inhuman by the public, and most are captured by governments. On paper, governments claim to protect Ajin, but in reality, most governments use them as subjects for cruel and inhumane experiments, as their abilities to completely recover from fatal wounds provides an unlimited source of organs and bodies in dangerous tests (such as live-fire weapons testing). As a result, Ajin that have escaped from government custody (such as Satou, the main antagonist) are bent on exacting revenge from governments – with the exception of Kei, who wants no part in the emerging Ajin-human conflict. However, in an agreement with Japanese governmental agents, Kei agrees to fight against Satou in exchange for his freedom from government experimentation.
- Kei Nagai (永井 圭 Nagai Kei)
- Voiced by: Mamoru Miyano (Japanese); Johnny Yong Bosch (English)
- Played by: Takeru Satoh
- The protagonist who first discovers that he is an Ajin after being killed in a traffic accident. To his peers, he appears to be a normal and carefree student, but in reality he is emotionally detached from other people and often willing to endanger the lives of other people in order for him to accomplish his own goals. He differs from most Ajin as he has the ability to create an abnormally large amount of IBM (Invisible Black Matter, which is key to an Ajin's regeneration and ability to create "black ghosts"), allowing Kei to manifest more "black ghosts" than his Ajin peers. According to Ikuya, he is implied to have manifested his Ajin-related abilities at a very young age.
- Kaito (海斗)
- Voiced by: Yoshimasa Hosoya (Japanese); Bryce Papenbrook (English)
- A close friend of Kei who helps him to escape from the police. He was later sent to prison for assisting in Kei's escape and later befriends Takeshi, another Ajin, allowing Kaito to escape imprisonment.
- Kō Nakano (中野 攻 Nakano Kou)
- Voiced by: Jun Fukuyama (Japanese); Griffin Burns (English)
- Kō is an Ajin and a partner of Kei with the intention to stop Satō, as Satō's plans for the creation of an Ajin-led government will lead to the loss of many human lives. Unlike Kei, who is indifferent and cold to others, Kō values friendship and is willing to put the safety of others above his own. He is also physically fitter than Kei, but lacks Kei's intellectual capabilities, often relying on Kei for planning in combat operations, with him acting as the "muscle" of the operation. Kō has the rapid regenerative abilities common to Ajin, but lacks the ability to manifest his own "black ghost".
Ministry of Health, Labour and Welfare
- Yū Tosaki (戸崎 優 Tosaki Yuu)
- Voiced by: Takahiro Sakurai (Japanese); Todd Haberkorn (English)
- Played by: Tetsuji Tamayama
- Yū is the head of Ajin Research under the Ministry of Health, Labour and Welfare and has a comatose girlfriend, Ai. He is protected by an Ajin bodyguard named Izumi Shimomura. He agrees to let Kei work with him to stop Satō on the condition that Kei is allowed to live a normal life afterwards.
- Izumi Shimomura (下村 泉 Shimomura Izumi) / Yōko Tainaka (田井中 陽子 Tainaka Youko)
- Voiced by: Mikako Komatsu (Japanese); Cristina Vee (English)
- Played by: Rina Kawaei
- Izumi is a stoic and taciturn Ajin working for Yū Tosaki at the Ministry of Health, Labour and Welfare. Izumi's birth name is Yōko Tainaka. As Yōko, she first discovered her Ajin abilities in her teenage years, when she first died after defending herself from a rape attempt of an abusive stepfather. Yōko would run away from home, where she is eventually recruited by Yū as a bodyguard under a special contract. The contract allowed Yōko to adopt the alias of "Izumi Shinomura", such that "Yōko Tainaka" is legally deceased and that "Izumi Shimomura" is a separate identity. She affectionately refers to her “black ghost” as “Kuro”.
- Sokabe (曽我部)
- Voiced by: Kenichi Suzumura (Japanese); Martin Billany (English)
- Yū's junior at the Ministry who was also assigned to supervise Yū. After Yū decides to defy orders from the Minister of Health, Labour and Welfare, Sokabe was appointed as his successor.

- Voiced by: Hōchū Ōtsuka (Japanese); Pete Sepenuk (English)
- Played by: Gō Ayano
- The leader of the pro-Ajin movement, also known as Hat (帽子 Boushi) due to his signature deerstalker hat, Satō is a calm and collected individual who is well-known within the Ministry of Health, Labour and Welfare as the most dangerous Ajin. Despite his appearance as a genial old man who enjoys video gaming, he is in reality a sinister, calculating tactician with combat experience as a former special-operations soldier in the USMC. Satō originally claims that he wishes to protest against the mistreatment of Ajins worldwide, but it is later revealed that he uses this claim as an excuse to gather an army of Ajin under his command to create an immortal army to rule Japan and simply for the sake of violence and destruction. He is frequently described as a "player" in the latter half of the anime, as he is prone to using strategies adapted from video games to carry out assassinations of famous politicians in order to force negotiations with the government for allowing rights of Ajins. He enjoys the use of violence against anybody (human or Ajin) who attempts to disrupt his plans and is especially irked by provocation.
- Kōji Tanaka (田中 功次 Tanaka Kouji)
- Voiced by: Daisuke Hirakawa (Japanese); Keith Silverstein (English)
- Played by: Yu Shirota
- He is the second Ajin to be discovered in Japan. He was rescued by Satō from brutal experimentation and joins in with his pro-Ajin movement against the Japanese government.
- Masumi Okuyama (奥山 真澄 Okuyama Masumi)
- Voiced by: Hiroyuki Yoshino (Japanese); Lucien Dodge (English)
- Played by: Yudai Chiba
- Masumi is one of the few Ajins who accepts Satō's invitation to use genocide to fight for Ajins' rights. He is a skilled hacker knowledgeable in weaponry and machines. In the anime, he eventually betrays Satō and reaches out to Kei in order to defeat him.
- Takeshi Kotobuki (琴吹 武 Kotobuki Takeshi)
- Voiced by: Sōma Saitō
- A prisoner who had escaped from jail after seeing Sato's announcement to protest for Ajins' rights. Takeshi becomes Kaito's partner after Kaito helped him when he was bullied by the other prisoners wanting to know how he had escaped from jail. His IBM is shown to have wings, which was his means of escape from prison. After he and Kai reconcile he promises to let Kai use his IBM to escape prison if, for whatever reason, he wishes to escape in order to assist Kei. In the anime, Takeshi uses his IBM to bring himself as well as Kai to Eriko's hospital in order to save both her and Kei from the riots occurring there.

In February 2014, Vertical announced that it had licensed the series for English release. On March 15, 2014, Crunchyroll began to release the series on their manga service under the title Ajin: Demi-Human, starting with the first two chapters.
