Plot: Saki Miyanagi, a high school freshman, hates mahjong because her family would always force her to play it and punish her regardless of if she won or lost. Because of this, she learned how to keep her score at zero, neither winning nor losing. However, her friend from middle school convinces her to join the school's Mahjong Club. After the Club discovers her ability, they recruit her and convince her to win instead of breaking even. She easily does so with her skill, so the team enters a mahjong tournament so that its members may reach the national competitions.
