After choosing to disband the Kawahara-gumi, Kiryu is left in possession of a massive cache of the syndicate’s firearms. Unsure of how to dispose of them, he takes advice and puts the weapons up for sale at an underground auction. However, waiting at the venue is Kamiya of the rival Daido-kai—a man bound to Kiryu by old grudges. With an enormous stockpile of guns on the line, a brutal firefight erupts.
