Super Real Mahjong PVI

The game introduces a "heart-pounding emotion system" in which the heroine's opinion of you changes depending on how you play mahjong. The story is about a player who, by chance, helps an elderly mahjong master named Tobe Kayama. When asked to express his gratitude, he blurts out, "I want to marry you!" As a result, he ends up competing in mahjong matches with his granddaughter, who has been introduced to him as a potential bride, and the heroines, who are his disciples.
