Nangou is a compulsive gambler who has racked up over three million yen in debt. In a desperate attempt to clear his record, he decides to bet his life on a game of mahjong against the mafia. Unfortunately, as the game unfolds, Nangou only drifts further from the prize and closer to death. When all hope seems lost, the game parlor is suddenly interrupted by Shigeru Akagi, a young boy on the run from the police. Eager to turn the game around, Nangou hands the game over to Akagi after teaching him a few rules. The mafia can only smirk as Akagi sits down to play. However, they soon discover that Akagi is a natural-born gambler. An imposing figure who does not fear death. One who is destined to become a legend.
