禁断へ導く女

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.
