Travail plot
Asami Honjo (Asaka Seto) is a professional Shogi player, and even a minor celebrity in that world. She has achieved champion status and her matches can sometimes be followed on television. Asami's sister Rina is an even bigger celebrity in the Shogi world. However, there is something the two sisters are less good at, which is maintaining their relationship with men. Asami is married to Kazuya, and although they have no money worries and live in a nice apartment, they are unhappy and quite aloof with each other. Rina's friend Hiroki and Asami, on the other hand, get along well. And vice versa, Rina gets on well with Asami's husband Kazuya. Things really come to a head when Rina and Asami have to play a Shogi match against each other.
