There are gamblers out there who even bet their lives as ante. But to secure the integrity of these life-threatening gambles, a violent and powerful organization by the name of “Kagerou” referees these games as a neutral party. Follow Bak Madarame a.k.a. Usogui (The Lie Eater) as he gambles against maniacal opponents at games – such as Escape the Abandoned Building, Old Maid, and Hangman – to ultimately “out-gamble” and control the neutral organization of Kagerou itself.

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.
