The protagonist, Masaru, has just inherited a big fortune after the death of his father. However, people are trying to get their hands on it by any means necessary, even if it means killing him. Narumi helped Masaru to avoid being kidnapped after fighting some weird guys. He found out that they're not humans but wooden puppets with amazing strength. After a hard fight, Narumi was forced to admit that he's no opponent for them, and just when he started to think that Masaru would be captured, Shirogane, Masaru's watcher, arrives from France with a weapon, the puppet Arlequin.
