In the 1970s, 80% of mahjong parlours in Kabukichō were "Buu Mahjong" establishments, where cash flowed freely in high stakes games. In this city that never sleeps, Shoichi Sakurai—known as the “Legendary Mahjong Demon”—enjoyed high stakes matchups with men who shared his love for the game. Shoichi Sakurai, who carried his winnings about without a care; a pickpocket who set his sights on that money; a self-proclaimed disciple of the “Mahjong Demon” begging for money; a man who only aimed for a “National Treasure” hand; a legendary hitman; a hitman for a rival yakuza gang, and more—the lives of gamblers living in Kabukichō intertwine.
