Ajin: Demi-Human (Japanese: 亜人 Hepburn: Ajin?) is a Japanese manga series written and illustrated by Gamon Sakurai. It was adapted into an anime 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 is scheduled for release on September 30, 2017.


The story is about a student named Kei Nagai (永井 圭 Nagai Kei?), who discovers he is an immortal "Ajin" when he is hit by a truck. He becomes a wanted person because the Ajin are considered dangerous inhuman beings and the only person who is there to support him is his childhood friend, Kaito. While the government claims to help Ajin live in a safe environment, they are actually using them as subjects for cruel and inhumane experimentation. As a result, Ajin that have escaped are bent on revenge with the exception of Kei. During his escape it is subtly revealed he lacks the capacity for empathy and throughout the series only shows an interest in his own goals, however he actually tries to hide his feelings and cares about people closest to him.

Despite his appearance as a white-haired friendly old man, in reality he is merciless, calculative and an extremely talented tactician, especially in combat as he is a former military soldier. Satō originally claimed that he wished to protest against the mistreatment of Ajins worldwide, but it is later revealed that he used this claim as an excuse in order to gather an army of Ajins in order to create an immortal army in order to rule Japan. He is frequently described as a "player" in the latter half of the anime, using strategies picked up from video games in order to carry out assassinations of famous politicians in order to negotiate with the government for allowing human rights of Ajins. This was revealed to be an excuse in order to wage war with the country simply for the sake of violence and destruction, with the end result of him ruling the nation.

Sato changes his looks while his assistants buy airline tickets. Kei and Ko undergo physical training while Tosaki tries to devise a plan to catch and hold Sato. Izumi takes them to meet Ikuya Ogura who asks Kei to bring out his IBM and then carries out some tests. He confirms that the IBM does the opposite of what Kei tells it, that it can acts on its own impulses, but that not all IMBs behave in the same way, depending on the host person. Sato boards a plane carrying Kazuo Sakurai, one of his assassination targets, and smuggles a bag on board with the help of his assistant Okyuama's IBM. Once airborne, he kills the man and his guards, then detonates a bomb forcing the plane to land in the sea. Meanwhile during training, Kei cautions Ko against becoming too friendly with the Ministry’s troops as they may have to be sacrificed to capture Sato, surprising Ko with his apparent callousness. Later, Kei experiments alone with his IBM, but finds that it is more difficult to control than he thought.

Tosaki’s team continue training and preparations, learning more about IBMs using Ogura’s knowledge. Kei contemplates the need to change his behavior, and his lack of empathy for others.

Sometime later, Tosaki revealed that her mother and stepfather died in a fight when her mother attacked her stepfather after Yoko fled the house. Meanwhile Almeida mercilessly tortures Tosaki to discover the whereabouts of Ogura but he won't talk. When she recovers, Shimomura tells Kei and the others what happened. Kei decides to move their hideout rather than rescue Tosaki to Shimomura's horror. She forcefully convinces Kei that she and Tosaki are necessary to defeat Sato, so they prepare a rescue plan. Kei's team raid the safe hideout where Tosaki is being held, but Almeida and Myers escape with him, while Almeida cruelly berates Myers for what he sees as her faults. Kei and the team give chase by car, but Almeida heads for the USA Embassy.

Myers disables Shimomura, but while Almeida berates Myers again for her failings, Shimomura shoots him instead of Myers with a tranquilizer dart to shut him up. Angry at her treatment, Myers then takes his gun and kills him, leaving to start a new life. When Tosaki awakes, he's angry that his team rescued him instead of following their plan to trap Sato. Meanwhile, Sato has ambushed the Minister. The Minister tries to make a deal, but Sato kills him anyway. Kei sends an email to the Americans saying that Sato has Ogura to send them after Sato. Meanwhile, Sato announces that he will kill the remaining target, President Hashiguchi of Musashi Heavy Industries, at a Directors meeting in 3 days. Chief Cabinet Secretary Mitsui announces a new powerful Anti-Ajin Special Force. Tosaki says that this has obviously been in preparation for some time and that they have a new inhumane weapon. Nevertheless, Tosaki and Kei agree to continue their objective of stopping Sato themselves.

Although there are some misgivings in Sato's group about his strategy, the Ajin realize their best chance is to stay with him. Sato tells Nekozawa who provided special technology to leave as things are getting kind of tough in this country, which he plans to rule. Kei outlines their new plan which assumes Sato will be successful and so they decide to attack after he defeats the anti-Ajin forces. Tosaki blackmails Sokabe into helping him get access to the Musashi Heavy Industries building and to be reinstated. On the day of the Musashi Heavy Industries meeting, Sato commences his attack, outwitting the government forces by taking out all electronic devices with an EMP.

Sato's group reach the upper floors, but they encounter Kei's group who are already in position. When Sato reaches the meeting room, Kei already has President Hashiguchi prisoner, threatening to kill him and deprive Sato of his victory. Sato appears to be defeated and is shot with tranquilizer darts. Although unconscious, his IBM is still active and it takes out Kei's group and 'resets' Sato by killing him. Sato then kills all the human members of Kei's group when they try to stop him and Kei is unable to activate his IBM. Suddenly more anti-Ajin forces attack by helicopter and force Sato's group to retreat with the company president whom Sato kills to gain access to a store chemical weapons. Kei, Shimomura and Ko are arrested by Sokabe who plans to have them tried as accomplices, but Tosaki tranquilizes Sokabe and frees them.

Sato's group assaults and easily captures a Self-Defense Force base and sets up missile launchers armed with nerve gas stolen from Muhashi Heavy Industries. In his broadcast from the base, Sato announces the beginning of his third wave and demands that the Japanese government turn over all state of affairs to the Ajin in one week’s time. Failure to meet this deadline will mean that he will launch the chemical missiles and exterminate all humans in Japan. Watching the broadcast, Tosaki realises that it is now everyone's problem and encourages the group to stop Sato once more. Kei however refuses to do so.

He gives the Japanese government 3 days to surrender before he launches all his missiles. Meanwhile, Sato's demands and game-playing cause dissension in his group as it will escalate their war, so most plan to desert him. The launch motivates some civilians to hunt down families of Ajin, including Kei's sister Eriko at the hospital. Kei intervenes to save her, but his IBM will not appear. Fortunately Kaito appears, accompanied by his fellow cellmate Kotobuki with his IBM to save them. After subtly telling Kaito to look after Eriko, Kei decides to return to Tosaki's group in order to stop Sato. The Japanese forces try a sneak attack on Sato but fall into a trap and are killed.
