posted on by Anita Tai
Joker Game creator Kōji Yanagi's novel Unbreakable ~Yaburezaru Monotachi~ (Unbreakable: The Undefeated) will get a manga adaptation by newcomer Tamaki Kaigane in this year's 18th issue of Akita Publishing's Young Champion magazine on August 26.

The story of the novel is set during the Peace Preservation Law of 1925, which targets those who believe in "Marxist" ideology. Proletarian writer Takiji Kobayashi chooses the harsh working conditions of a crab cannery ship as the subject of his next novel, which draws the attention of the special police task force charged with monitoring ideological threats. Two spies are sent to monitor his activities.
Kadokawa published the novel in 2024.
Yanagi published the original Joker Game novel in 2008. The novel won the Nihon Suiri Sakka Kyōkai-shō (Mystery Writers of Japan) award in 2009. Yū Irie directed a live-action adaptation of the novel, which premiered in Japan in January 2015. Yanagi followed up the original novel with three sequel novels — titled Double Joker, Paradise Lost, and Last Waltz — in 2009, 2012, and 2015, respectively. The series has more than 1.35 million copies in print.
Production I.G's television anime adaptation of the novel premiered in April 2016. Crunchyroll streamed the series as it aired in Japan, and Funimation streamed an English dub for the anime.
Subaru Nitō ended the manga adaptation of the anime in 2018. Nitō launched the manga in Comic Garden in February 2016.
The series inspired a stage play adaptation of the anime in 2017, with a second stage play in 2018.
