1995, Kamurocho... An up-and-coming yakuza takes the fall for the murder of a crime boss to protect his sworn brother and his childhood friend. This man is none other than Kazuma Kiryu, the legendary Dragon of Dojima. After a decade, Kiryu is released from prison to a world he no longer recognizes. His own organization has turned against him, and various conspiracies threaten to tear the streets of Kamurocho apart.

A mysterious young girl named Haruka Sawamura suddenly appears before Kazuma Kiryu. Having come to Kamurocho in search of her mother, Mizuki, Haruka reveals crucial information that cuts to the heart of the case. As Kiryu continues his search for Yumi, he seeks out the aid of the Florist of Sai. A brutal clash with Goro Majima, mounting pressure from the police, and the wild ambitions of Akira Nishikiyama draw Kiryu ever deeper into a web of conspiracies far greater than he ever imagined.

As Kazuma Kiryu closes in on the truth, Terada, the Fifth Chairman of the Omi Alliance, leads him to a reunion with Shintaro Kazama. There, Kazama reveals his convictions, the truth behind Yumi's disappearance and the missing 10 billion yen—including the identity of the shadowy mastermind responsible. The situation quickly spirals as a clash with the Shimano Family turns deadly. Returning to Kamurocho, Kiryu and Haruka must press on, but what will they find at the end of their journey?
