Barely surviving thanks to his online experience, he decides to adjust his playing style for real mahjong. At that time, his ex-wife, Hanako, suddenly collapses and Rinji has to take care of his daughter Koume. Not being able to pay for the living expenses he decides to feed himself and his daughter with mahjong. However, Hanako's colleague from work, Arino, confronts Rinji telling him he proposed to Hanako and asking if his mahjong is strong enough to feed and protect a family. Arino challenged Rinji in a mahjong match for the right of protecting Hanako and Koume, with two mahjong pros, Gouno and Hira, participating. It became an intense match with Gouno and Hira betting their pride, Arino thinking of a family life with Hanako, and similar motives clashing, however, Rinji proved his determination and ability to take care of his family and was the overall winner of the night.
