Jagan Wa Gachirin Ni Tobu

From Blackout: 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 from 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. Here, begins the story of Karakuri Circus.

It centers around the travails and battles of one Ushio Aotsuki (??? Aotsuki Ushio), who is constantly being stalked and aided by a gigantic, supernatural and sometimes invisible tiger (Some people describe it as akin to Calvin and Hobbes on acid, but I disagree). Ushio's family maintains a Buddhist temple in Japan, where ~500 years ago, his samurai ancestor battled that same tiger to a standstill, and eventually trapped him against a rock using a blessed spear called the "Beast Spear", which in addition to its intrinsic formidability as a weapon, can also boost the physical powers of the user. While cleaning out the temple storage, Ushio accidentally unseals the chamber Tora was trapped in. Initially, Ushio wisely refuses to remove the spear pinning Tora (??, Japanese for tiger) down, as Tora unwisely makes the strategic blunder of mentioning that the first thing he would do upon being freed would be to devour Ushio; but Tora's unsealed presence attracts various demons to the premises, and Ushio is forced to free Tora in exchange for his help. The series focuses on their relationship, interspersed with battles against mythological foes, and with Tora's attempts to grapple with modern life and gobble up Ushio. * volume 34 is actually the side story volume (gaiden)
