Corrupt magistrate who has no qualms about extorting the townsfolk he governs. Evokes the irritation of Jin, who cuts down his bodyguards, the Yagyu Three, to express his dissatisfaction. The last straw arrives when Shibui incarcerates and sentences Jin (along with Mugen) to death for the murder of his son (which Mugen had plenty to do with and Jin nothing). Upon escaping, Jin recites a Buddhist proverb on mercy being granted only once and executes him just as he intended to execute Jin. Shibui's pipe reappears when Fuu needs a light, and the pipe is given to her by the man whom Shibui was going to execute.
