A shady government spy who is also sent to investigate and stop the Eight Demons of Kimon and their employer, the Shogun of the Dark who wishes to overthrow the government. He commits Jubei to his cause by stabbing him with a poisoned shuriken and promising him an antidote and 100 pieces of gold only after the demons have been defeated. When he is attacked by Shijima, Dakuan demonstrates his ability to blend into his environment, like a chameleon, disguising himself as a tree branch to avoid confrontation.
