Confrontation
It has been a week since Saki joined the mahjong club, though Nodoka is still distant to her. Nodoka plays a game by herself with all the tiles exposed and takes notes, but she is still unable to attain a plus/minus zero score like Saki who can do this flawlessly. Hisa and Mako go and sign up their club for the national qualifiers for high school students. Saki wins a game against Nodoka, Kyōtarō, and Yūki, who is depressed that she cannot possibly win when playing against both Saki and Nodoka. In the next game, Saki lets Yūki win, which makes Nodoka angry since while Saki did it so that everyone can have fun, Nodoka can only have fun when Saki is playing at her best. Saki makes a promise with Nodoka to shoot for the nationals, and the two finally become friends.

Saki
Miyanaga Saki is a first year high school girl whose family would get angry if she won the family mahjong games. But losing would also have its consequences. Because of this she develops a new way of playing that allows her to stay on the thin line between winning and losing, the plus/minus zero score, an almost impossible score. In a game that relies mainly on luck, the plus/minus zero score is harder than winning, but Saki can achieve this every time.
Having always hated the game, her friend from middle school, Suga Kyotoro, forces her to play in the schools mahjong club. Her developed skill and superhuman luck has made her a worthy mahjong opponent, even to the middle school's national mahjong champion.
