King Records began streaming a commercial for the second season of the Ajin television anime on Friday. The video reveals and previews the anime's opening theme song "Boku wa Boku de Atte," a collaboration song between the groups angela and fripSide.

The anime will premiere on MBS and TBS on October 7, and on BS TBS on October 8.

The anime project adapts Gamon Sakurai's Ajin: Demi-Human manga. In the manga's story, an immortal first appeared on an African battlefield 17 years ago. Later, rare, unknown new immortal lifeforms began appearing among humans, and they became known as "Ajin" (demi-humans). Just before summer vacation, a Japanese high school student named Kei Nagai is instantly killed in a traffic accident on his way home from school. However, he is revived, and a price is placed on his head. Thus begins a boy's life on the run from all of humankind.

The first season of Ajin premiered on January 15 and ran for 13 episodes. Netflix streamed new episodes in Japan three days after they premiered on Japanese television, and it began streaming the entire first season outside of Japan on April 12.

Polygon Pictures animated the television anime, and it is also animating the three-part anime film adaptation. Additionally, the television anime and anime films also feature the same main staff. The first film, titled Ajin: Shōdō, opened in Japan last November. The second film, titled Ajin: Shōtotsu , opened on May 6. The third film, Ajin: Shōgeki (Ajin: Crash), will open in Japan on September 23.

A limited edition of the eighth volume of Gamon Sakurai's original manga also bundled an original anime DVD on May 6. A limited edition of the ninth volume will also bundle an OAD when it ships on October 7.
