Story : Momoko continues to put the pressure on Tomoki and Hisa keeps racking up strong plays, while Saki is still unable to use her usual strategy. Saki remembers her training using online gaming, and uses what she learned to pick out Momoko's tiles, finally allowing her to play a rinshan kaihō to win the match. In the final round, Hisa goes against Mihoko, Tōka and Yumi, Nodoka goes against Kana, Jun and Hajime, Yūki goes against Mako, Tomoki and Momoko, and Saki goes against Kazue, Kanbara and Yoshitome. As everyone battles their hardest, Yoshitome does well to block off Saki in the east wind round, but soon the south wind round comes and Kazue starts to make her move. However, Saki retains her smile and pulls out more rinshan kaihō moves to win her match, placing third and qualifying for the nationals. Nodoka wins her match and qualifies in second and although Hisa wins her match, Mihoko is overall first place.
