Otawa Hankichi

Debut: Episode 15 "Bogus Booty"

A young shogunate ninja with a highly distracting facial mole and Yatsuha's underground counterpart. Before the story begins he apparently steals some of the forged koban to present as evidence. He ditches the gold in the river

[Spoiler] (where it is later found by Jin) but gets caught and withstands torture to protect Yatsuha's cover. Rescued (inadvertantly) by Mugen in a very painful state. Appears again at the end of the episode, leaning the unconcious Mugen against a tree outside of town, and expresses disbelief at Yatsuha's taste in men. [/Spoiler]
