Juzo was the drunken brother of Magistrate Sueoka. He and his brother were responsible for the murder of a farmer who discovered gold in a nearby valley. He also hired a group of assassins known as 'Shi' to do away with the villagers of his brothers town as well as a certain meddlesome ronin rabbit.

What his brother did not realise is that he had also hired them to kill the magistrate. The magistrate showed up in Juzo's room the night the Shi assassins were killed however and attempted to kill Juzo, who fully expected this and had prepared.

Being the better swordsman, Juzo slew his brother, but this was witnessed by the magistrates guards and Juzo himself was in turn slain.
