It was first released in Japan on December 23, 2006. The story takes place in the fictional Treasure Town and centers on a pair of orphaned street kids - the tough, canny Black and the childish, innocent White, together known as the Cats - as they deal with yakuza attempting to take over the city of Treasure Town. The manga was released in North America on October of 1998 and was re-released on September 25, 2007 as a compilation of three comics in one.
In Treasure Town, orphans Black and White rule the mean streets through violence and terror. These lost boys are direct opposites: Black being a streetwise punk who embodies everything wrong about the city, while White is a innocent dope, out of touch with the world around him. They're on the quest to prevent a yakuza plot to turn this city into a amusement park. Together, they're unstoppable as they take on petty thugs, religious fanatics and brutal yakuza. But when a corporation called "Kiddy Kastle" tries to tear down and rebuild Treasure Town to fit its own goals, the boys must save the soul of their beloved city, that is if they can save themselves from inner demons.
