The Kanto-based Aoi-kai seeks nationwide domination and sets its sights on the Nagano-based Taketomi-kai. Tokunaga (Kiyoshi Nakajo), chairman of the Aoi-kai, launches an assault to bring them under his control. Eventually, Taketomi-kai’s leader Katsuo Taketomi (Yuichi Kimura) is gunned down, forcing the group to disband. As a result, Masaki Koda (Koichi Miura), father of Shinichi Koda (ISSA), announces his retirement. Shinichi, once a civilian running a construction business, loses everything as Aoi-kai expands into Nagano. Burdened by a promise to his father, the loss of his work, and his strained relationship with his half-brother Shigekazu (Yoshiyuki Yamaguchi) of the Aoi-kai, Shinichi heads to Kanto to fight back. Determined to live with pride, Shinichi’s resolve draws a group of unique, fearless men around him. Together, they ignite a fierce yakuza battle that marks the beginning of an epic underworld saga.

To crush the Kanto-based Aoi-kai aiming for national domination, Shinichi Koda (ISSA), president of Koda Construction, heads from Nagano to Tokyo. At the request of Asagiri (TJ Kayama), he helps the former Hanazono Union leader, now on the run from the Aoi-kai. Shinichi’s former mentor, Takeharu Mori (Tetsu Watanabe), president of Mori Industries, is being driven to the brink of bankruptcy due to an eviction dispute with the Aoi-kai. Seeking a trigger to start the fight, Shinichi asks Mori for his cooperation. At last, the ten brave men are assembled. With his father's banner—the Koda-gumi—raised high, Shinichi leads them into a fierce war against the mighty Aoi-kai. "Now, brave men... it's time to rise."
