Akira runs away from Yakuza and bumps in a young passerby girl. Trying to get rid of the pursue, he masquerades himself as the girl's boyfriend, but instead he gets her involved into the trouble. Successful to escape by himself alone, he witnesses the girl being kidnapped. Unwilling to help her, he leaves the town and forgets about the incident.

Two years later, he is back in that town; but shortly after having arrived, he is attacked on the street, and robbed of all his possessions. Now he has to get to the bottom of the mystery, but first he needs money. Since the town is big on mahjong tournaments, the hero decides to get his money back by playing that game, at the same time investigating the townspeople... in more than one way.
