## Plot

Madarame Baku, known as The Lie Eater (Usogui), is a master gambler who thrives on high-stakes games against ruthless and maniacal opponents. Alongside his loyal protege Kaji Takaomi and his formidable bodyguard Marco, Baku sets his sights on taking control of Kakerou, an underground gambling organization that oversees life-threatening wagers.
Kakerou ensures the integrity of these extreme gambles by acting as a neutral referee, with 48 elite members and 101 referees who supervise the games and enforce their outcomes. These referees are also tasked with collecting debts, even when the stakes involve participants' very lives.
As Baku delves deeper into the shadowy world of Kakerou, he and his crew find themselves entangled in a fierce conflict with a rival criminal organization known as IDEAL. The stakes grow ever higher as Baku faces off against opponents in ingenious and deadly games such as "Escape the Abandoned Building", "Old Maid", and "Hangman".
Through his cunning, daring, and unmatched gambling skills, Baku navigates a world where every move could be his last, risking it all to claim dominance over Kakerou and survive the deadly games that come his way.
