Kazuki Fuuchouin is one of the former Emperor of the Volts, currently working as a guiding agent in Shinjuku. Kazuki is the one to go for if you want information on just about anything; chances are, he knows all of your secrets, too. He keeps in close contact with Shido and Ginji, but he doesn't usually work with them. Kazuki fights with strings, as one might expect from the Fuuchouin String Style; there are a great many elusive fragments of this art that can't be traced. However, it is an incredibly flexible skill—he can overhear conversations that take place in the presence of one of his strings, change his physical appearance and voice, sew people's mouths and eyes shut.
