Plot
Ajin presents the story of a student named 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 immortality and extreme regenerative abilities that trigger upon death, allowing them to completely recover from any mortal injury in a matter of seconds. Ajin can also create "black ghosts", highly dangerous combat-oriented entities that are only visible to other Ajin. "Black ghosts" are resistant to physical injury, exhibit extraordinary physical strength, and have sharp teeth and claws. Different "black ghosts" have varying degrees of intelligence: most are completely reliant on their Ajin for directions, and others, such as 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.
Governments claim to protect Ajin, but in reality, most 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 on governments.
Kei, however, wants no part in the emerging Ajin–human conflict, but forms an agreement with Japanese governmental agents to fight Satou in exchange for his freedom from government experimentation.
Characters
Kei's Group
Kei Nagai (永井 圭)
Played by: Takeru Satoh
Kei 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)
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)
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)
Played by: Tetsuji Tamayama
Yū is the head of Ajin Research under the Ministry of Health, Labour and Welfare and has a comatose fiancée, 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) / Yōko Tainaka (田井中 陽子)
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)
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.
Ajin

Played by: Gō Ayano
The leader of the pro-Ajin movement, also known as Hat (帽子) due to his signature flat cap 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.[3] 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)
