A manga by Kazuhiro Fujita (the same guy who did Ushio and Tora
), placed in relatively modern-day Japan. The manga employs an unusual "choice-based" style, where it shows the two decisions a character can make at a pivotal point in a pair of boxes, a fancy arrow pointing to the decision made. The first decision is by Narumi, a sick Kung-Fu champ who decides that his job, passing out circus flyers, is more important than helping a young boy FIND the circus. He changes his mind when a group of well-dressed thugs attempt to kidnap the boy, as he rushes to save the day (still in his bear costume for work).
Then he finds out that the men after the kid, Masaru, are not men...they're dolls. Their masters are the would-be heads of a large financial empire, of which Masaru is the heir. Rescued by a mysterious silver-haired doll user named Shirogane, Masaru goes forth the find out just why the dolls and their users are after him.
