Professional mahjong player Akari Asada couldn't accept her rival Yumi Shimamura's suicide. Asada proceeds with the investigation to uncover the truth. He finds out that the real cause lies in Takagi, the chairman of the All Japan Federation, known as the Don of Mahjong. Takagi used his power to steal the bodies of many female mahjong players. In order to stop Takagi's misdeeds, Asada presents him with a challenge that if he wins in a mahjong match, he will be forced to resign. With the cooperation of the legendary female mahjong player Kawagoe, Asada begins intense training with the goal of "defeating Takagi". A spectacular mahjong showdown that no one has ever seen has begun!
