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 was released 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 is wanted by the government 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, Ajins that have escaped are bent on revenge – with the exception of Kei, who wants no part in the Ajin conflict. Kei is initially shown to lack empathy for others, even the people closest to him, but as Sato's actions become even more extreme, he eventually joins the fight to stop Sato's violent campaign.

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.
