A man who wins mahjong only by waiting for his opponent to give him victory. Every hand he plays is a study in patience, calculation, and the razor-thin line between control and surrender. This OVA understands that the real game isn't about the tiles, it's about reading the person across the table and knowing exactly when they'll crack under their own hand.

Ryuu, known as the Crying Dragon, is a mysterious man who often sits down to play mahjong with gang members. He wins in only one way: by ron, waiting for an opponent to discard the exact tile that completes his hand. In mahjong this move is also called naki, which sounds the same as the Japanese word for crying, and that is where his nickname comes from. The three-episode drama OVA is based on a mahjong manga by Nojo Junichi.
