Now, Zatoichi must step in to save the day.

Zatoichi is forced to kill a young man who owes a debt to a yakuza boss. Moments later, his sister Osode arrives with the money she earned (prostituting herself) to pay his debts.

Osode and Zatoichi are caught in a dilemma as she must rely on her brother's killer for protection and Zatoichi wrestles with the injustice he has caused.

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.

Zatoichi makes friends with a dangerous chess player, while fending off angry yakuza and bloodthirsty relatives out for revenge, and trying to save a sick child. Meanwhile, his luck with dice is turning.
