The newly-promoted Shibusawa wishes to consolidate his position as Dojima's second-in-command, so he orders his men, as well as Awano and Kuze, to kill all of former Captain Kazama's supporters. Elsewhere, Kiryu gets wind of what transpired at Dojima's penthouse from Sera. He tells him Makimura survived the gunshot and that he'll be keeping her safe at the Nikkyo Consortium's hidden headquarters in Shibaura Wharf.
Soon after his conversation with Sera, Kiryu hears about Dojima Family goons heading for Kazama's office and correctly assumes that Shibusawa is making his move. Kiryu goes to the Kazama office, but is stopped in the street outside of it by Kuze, all on his own. After all the humiliations Kiryu subjected him to, all Kuze wants is to defeat him in order to recover his lost pride. The two engage in a final battle and, despite Kuze's determination, Kiryu bests him once again. Just afterwards, Nishiki and Kashiwagi emerge from the Kazama office, having defeated Kuze's men inside. A defeated Kuze admits to himself that he'll never beat Kiryu and then warns the three that Shibusawa knows about Sera's hidden base and is mobilizing his men to attack it. Kiryu and Nishiki decide to go ahead and warn Sera, while Kashiwagi goes to gather Kazama's men to provide back up.
Elsewhere, a furious Majima heads for the Dojima Family's offices, but is interrupted by Sagawa and some of his crew. When Majima tells him of his intentions, Sagawa threatens him, telling him that if he attacks Dojima, it will have negative consequences for Shimano and the Omi Alliance. Majima, no longer intimidated by Sagawa, quickly beats him and his men back before continuing towards Dojima's offices.
By the time Kiryu, Nishiki and Kashiwagi arrive at the Nikkyo's base in a docked yacht, Shibusawa's attack has already begun. While Kashiwagi and his men hold back Shibusawa's goons, Nishiki and Kiryu head aboard the yacht, where Shibusawa is searching for Makimura. Kiryu eventually manages to reach Shibusawa, who is holding an unconscious Makimura hostage. Shibusawa explains that, after years of being passed over for promotion because of more charismatic yakuza like Kazama, Kuze and Awano, he is finally getting the recognition he feels he deserves, and he won't let a low-ranking thug like Kiryu threaten that. Kiryu goads Shibusawa into a fight by calling out his power-lust and, after an extended duel, defeats him and rescues Makimura. Kiryu considers killing Shibusawa, but he is stopped by Nishiki, who insists killing a man once he's already been beaten would make Kiryu just as monstrous as Dojima and his goons.
Back in Shinjuku, Majima breaks into Dojima's headquarters. Since most of the Family's men were sent away for Shibusawa's attacks, Majima fights his way towards the Patriarch's office single-handedly. However, before he can get to Dojima, Majima is stopped by Awano, who recognizes him as one of Shimano's enforcers. Awano is puzzled as to why Majima would risk so much for a woman he barely knows, to which Majima responds by saying that he's come to enjoy living dangerously. Impressed, Awano challenges Majima to a duel, which he ultimately loses. The two are interrupted by Patriarch Dojima and Lao Gui, who attacks them both due to Awano's failure. Awano dies in the battle, but Majima ultimately manages to beat Lao Gui, much to Dojima's terror. Before Majima can kill Lao Gui, he is stopped by Sera, who arrives to inform Dojima that he's already lost, since Makimura awoke from her coma after being rescued by Kiryu and signed over the Empty Lot to him. Before Majima leaves, Sera hands him a gun and asks him to make Shimano "take responsibility" for his betrayal of the Tojo Clan.
Shortly after, Majima finds Shimano having a meeting with the Omi Alliance's Chairman and while Majima could've shot Shimano he refuses to do so, as he's loyal to the Shimano Family, and hands the gun to him. Shimano considers shooting Majima, as he asks his final request be to tell Saejima he's sorry, but instead shoots the Omi Chairman, proving his innocence while also likely starting a war with the Omi Alliance. Shimano tells Majima about his mindset and confidently states that while the Kazama Family and Nikko will fall, the Shimano Family will be at the top, especially with Majima at his side.
