A woman known as "Angel" suddenly appeared in the underground mahjong world. She gambled her own body through strip mahjong. But she was strong, and had never even been naked before. Angel had a reason for playing strip mahjong. She was searching for her father, from whom she had been separated. Her mother had apparently also played strip mahjong in the past. By doing the same thing as her mother, Angel was hoping to find a clue. And as Angel got closer to the truth, she challenged the yakuza to a match as their proxy player!
