In a match against his old rival, Kanata Kuji, Yuhi was defeated for the 17th consecutive time while Kanata set a record with his 27th consecutive win. Feeling down, Yuhi visits a bar where he meets a girl named Tsuki Kayamori. Despite her overbearing, self-centered, and eccentric personality, her unique and sharp playing style seems to be chosen by the shogi God.
