The Maizuru Showdown between The Yakuza Brothers

Repeatedly beat to a pulp by gamblers, cops, and gangsters, lone wolf Shoji Yamanaka finally finds a home as a Muraoka family hitman and falls in love with boss Muraoka's niece. Meanwhile, the ambitions of mad dog Katsutoshi Otomo draws our series' hero, Shozo Hirono, and the other yakuza into a new round of bloodshed.

Ryūichi and his small gang of Triad vie for control of the Japanese underworld in a crime-ridden Shinjuku quarter while Detective Jojima tries to bring it down.

In the teeming black markets of postwar Japan, Shozo Hirono and his buddies find themselves in a new war between factious and ambitious yakuza.

In an alternate version of 1949 Japan in which World War II never happened, the Japanese capital of Teito is home to both an ultra rich upper class and the dirt poor masses. The city is thrown into a state of panic when a phantom thief called “The Kaijin (Fiend) with 20 Faces” (K-20 for short) begins to use his mysterious abilities to steal from the rich and give to the poor. One day a circus acrobat named Heikichi Endo (Takeshi Kaneshiro) is framed for K-20’s crimes and becomes determined to clear his name. He teams up with K-20’s next target, a wealthy duchess named Yoko Hashiba (Takako Matsu) and her detective fiancé (Toru Nakamura), to take K-20 down once and for all.

A police investigator cracks down on yakuza business, but once he realizes the police are in negotiations with certain factions, he sides with his own syndicate of choice.
