Saki Miyanaga, a high school first-year student, does not like mahjong because her family would always force her to play it and punish her regardless of the outcome of the game. Due to this, she learned how to keep her score at zero, neither winning nor losing, a skill said to be more difficult than actually consistently winning. However, her friend from middle school, completely unaware of such circumstances, convinces her to visit the school's small mahjong club upon entering Kiyosumi High School. After the club discovers her ability, they recruit her permanently and convince her to win instead of breaking even. She easily does so with her skill and discovers a new love for mahjong, along with a friendship with her fellow club member, Nodoka Haramura. This leads the team to enter the prefecture's high school mahjong tournament with the goal of reaching the national high school competition.
