Saki

Kyōtarō tells Saki about an upcoming summer festival and she invites the rest of the club to go too. Hisa sends out invitations to the other schools to join them for Kiyosumi's training camp for the nationals. Yūki ends up flunking her math midterm and has to take a makeup test, failure of which means she will not be able to attend the camp, so Saki and Nodoka decide to help her study. Hisa prohibits them from using the club room and they end up having trouble finding other places to study. Ryūmonbuchi and Tsuruga send their responses for the camp, while Mihoko delivers hers to Hisa personally. After Yūki's makeup test, the club members go to the festival, and Hisa watches from afar with Mihoko. Yūki passes her makeup test and all the schools go to the training camp.

It is the second day of the individuals, and Yūki is shocked to find the day will consist of east-south round games. Yūki gets off to a good start in her first match, but when the south wind approaches, Kazue Nanpo from Hirataki High School shows off her field advantage and wins the game. During the midway point, Nodoka is shocked to find Saki has gone back to her habit of scoring plus minus zero, and goes to confront her about it. Saki had been holding back since it was Hisa's only chance at the individuals, but Nodoka reminds her that their promise included not holding back. Saki ends up in a match against Hisa, as well as Momoko and Tomoki. Hisa immediately concocts a strategy to seal off Saki's rinshan kaihō strategy, which eventually convinces the others to gang up on her. Later on though, Momoko, determined to avenge Yumi's earlier lost against Saki during the team tournament, decides to implement her stealth tactic in order to win.

As a reward for winning the tournament, and to train for the individuals, Hisa takes everyone to a pool, where Saki admits she cannot swim. They run into the Ryūmonbuchi group, who actually own the pool, and Koromo makes friends with Nodoka. Tōka reminds Koromo that when she went to Tokyo with her group, and went to a family restaurant, that reminded her of her parents. Meanwhile, Kazekoshi and Tsuruga make their plans for training for the individuals. Saki's sister, Teru, progresses to the nationals, though when asked about Saki, denies her existence.

Remembering the pact she had made with Mihoko, Kana gets a burst of confidence and regains a lot of points. Yumi also gets a good play, and Koromo, having paid all her attention to Saki, gets a little agitated. Saki takes off her shoes and socks, remembering the times she played mahjong at home and at the training camp.

As the round continues, Saki finally recognizes Koromo's aura. She starts putting pressure on her opponents by reducing their tenpai probabilities and playing two haitei raoyue moves in a row. However, this is broken up when Yumi allows Saki to win with a her discard. Yumi then follows this up by getting some points from Kana.

Tōka makes a slight comeback, ruining Nodoka's perfect run, but then falls into a play laid by Tsuruga's Momoko Tōyoko, whose presence is so small her calls for riichi cannot be heard by her opponents. She had trouble being noticed and had abandoned all communication until she was found by her school's mahjong club leader, Yumi Kajiki.

Mihoko arrives to pass along the information to her companion, and Hisa barely recognizes her. Koromo takes the torn penguin to her butler, who fixes it, and she returns it to Nodoka. While Nodoka expresses her gratitude, she leaves quickly and is unable to hear Koromo's name.

Hisa recommends Saki and Nodoka take a nap before their matches, and while Nodoka initially declines, she decides to go so that Yūki does not have to cry in front of her and Saki following her match. Mako's turn comes up, and Hisa explains that she takes off her glasses in order to remember past matches she had witnessed.

The Kiyosumi team takes the train back to town since they do not have enough money to stay in a hotel near the tournament. Hisa tells Mako how she was the reason why Hisa held on to the hope that more girls would join the mahjong club the next year so that they could go to the prefectural tournament together. Nodoka recounts to Saki how she used to play mahjong only on the Internet due to lack of players, but after entering junior-high school met Yūki and others, leading them to enter into the junior-high tournament, though only Nodoka advanced. The girls from Kazekoshi talk about how their captain, Mihoko Fukuji, does most of the work for the club, and since it is her last year, they want to play as hard as they can so they can go to the national tournament. Tōka dispatches a butler to bring Koromo Amae to the tournament, who had been sleeping all day.

After arriving at the tournament area, Saki gets separated from her friends, and during this time Nodoka gets hounded by reporters due to her having won last year's national junior high school tournament. After Saki makes it back to the others, Hisa explains the order of the players, starting with Yūki, followed by Mako, herself, Nodoka, and finally Saki. While initially underestimated by her opponents, Yūki wins many hands, nearly shutting out the others. Afterwards, Mako and Hisa also make quick work of their opponents, ending with a commanding lead. When it is Nodoka's turn, more people show up to watch her match.

Hisa announces to the club that they are now signed up for the national qualifying tournament, and she hands out the rules. Yūki sees that one school, Ryūmonbuchi, are extremely skilled and even won the tournament the previous year despite being all first-year students. Hisa asks Saki and Nodoka to help out at Mako's family's cafe, telling them that learning about the real world is also important to improve their mahjong skills. When they arrive at the cafe, they see that it is actually a maid cafe, and they have to wear embarrassing maid uniforms. Patrons can also play mahjong there, and Saki and Nodoka easily win against two customers. After one leaves, a woman who Saki is intimidated by joins them. The woman completely mops the floor with them, and at the end it is revealed that she is Fujita, a professional mahjong player. Saki and Nodoka later find out that Hisa set the whole thing up so that they could also feel what real defeat is like. Hisa explains that the club is going on a training camp to improve their skills.

Playing under special scoring rules, Saki plays the next game while trying to keep her plus/minus zero score and winning at the same time, but cannot do both with the special rules. However, when the special rules are removed, Saki ended up winning the game, therefore disallowing her from keeping the zero score. Nodoka is dejected after losing since before Saki told her that she hated mahjong and despite that won, but Saki tells her that playing with her was fun. Saki thinks about what Nodoka said, and even tells her father that she wants to one day play again with her mother and sister like they used to before they left to be professional mahjong players. The next day, Saki joins the club, saying that she wants to play more and win against Nodoka.
