He may be a relative of Johnny Zoo, the leader of the Yakuza in Anywhere City. He is a known criminal and is gambling addict, known as X-ray for his ability to read cards. He is also known to use amphetamines when playing cards for long periods. He has a shiny black S-Class Mercedes and prefers to use a silenced laser sighted assault rifle when killing people.
He was first arrested in 1994 on charges of suspected auto theft and possession of firearms although he was not sentenced to prison for these offences. A year later, in 1995, he was arrested again for being involved in an illegal gambling racket and was also charged with possession of firearms. He was sentenced to one year in prison. He spent 1996 in prison but after being released was arrested and charged with multiple murders in a gambling den. However, he was released on a technicality. He was also linked to a gambling racket and more gambling-related murders, although the police have no evidence to link him to the crimes.
On Funami, he's said of being a "car-criminal" and according to Jill Tasker on Lo-Fi, he's linked to criminal activities in casinos.
