Gyakkyou Burai Kaiji: Ultimate Survivor
Kaiji Itou is a drifting deadbeat who releases his frustration with life through vandalism. One day he learns that by unthinkingly co-signing on a former workmate's shady loan he has made himself liable for a crippling amount of compound interest.
The debt collectors offer Kaiji a deal: rather than slaving to pay off the loan for decades, he can take part in a special competition and clear it all in one night. This is his entry into a series of fiendish underground gambles.
Kaiji soon develops an unexpected knack for high-pressure strategy and mindgames. But he's trapped in a world where each seemingly simple game has hidden depths, where the rich pit the poor against each other for their own amusement, and where a single misstep can mean disfigurement or death. As the stakes rise higher and his fellow debtors are eliminated one by one, will Kaiji be cunning enough to escape, or even take some measure of revenge on the criminals exploiting him?
