In 19th-century London, class lines are sharply drawn, and the social standing to which people are born dictates the path their lives will follow. Emma, an honest and hardworking young maid, never felt her place in life to be a burden. But then she met William, a member of the gentry and the eldest son of a wealthy family. His warm smile and earnest affection threaten to capture her heart... but can love truly conquer all?

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.
