In a city where lawlessness rules, every day is a struggle for Yuki and his best friend Tetsu. In a desperate attempt to pay for his brother's hospitalization, he was forced to strike a deal with the Seidoukai; however, Yuki's dark past has finally caught up to him, dragging him back down into a tangled web of extortion and underworld deals. Ordered by the leader of a rival organization to get close to Hyoudo for nefarious purposes, he feels that he's left with no choice but to return to old and painful methods of survival just to get by.

However, Hyoudo's connection to Yuki runs deeper than that chance meeting. For years, Hyoudo has been searching for him, hoping to keep a promise he once made to Ryuuji, Yuki's father. But those simpler days of brotherhood and camaraderie are long gone, and as Masatsugu and Reiji's schemes herald a coming storm of violence and bloodshed, can Hyoudo still fulfill that promise and protect those he holds dear?
