Set in the fictional town of Kamurocho, the story unfolds across two intersecting timelines-1995 and 2005. In 1995, four friends eager to escape their restrictive lives in an orphanage dive into the yakuza-controlled underworld of 1995 Kamurocho. Meanwhile, in 2005, their friendship is deteriorated, as tensions between the Tojo Clan and the Omi Alliance are at a boiling point.
