Ten Warriors of the Underworld
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.
