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.

Nodoka walks into her match holding her penguin stuffed animal which causes a stir among the observers and her own opponents. Nodoka plays extremely well, and of the competitors from Ryūmonbuchi, Tōka, notices her similarities to a famous skilled online mahjong player known as Nodocchi. She tries telling this to her teammates, but they still do not think it can be true. Saki makes short work of her round by taking the remaining points from one of the players, and the team progresses on to the semi-finals round. In the semi-finals, Saki's team makes it through to the finals, along with Ryūmonbuchi, Kazekoshi, and Tsuruga Academy. One of the members from Kazekoshi, Kana Ikeda, gets harsh treatment from their coach for not playing up to her expectations, despite the fact they made it to the finals. The captain of the the team, Mihoko Fukuji protects Kana, and after the coach leaves, the captain encourages her teammates in showing everyone that their school is the best.

As the day of Kiyosumi's first round arrives, Saki states her determination to reach the finals before she can talk to Teru. After receiving some encouragement from Ryuumonbuchi and Tsuruga, Hisa receives a video from her school showing the support of all their friends and classmates. Moved by how many people have surrounded her in the past two years, Hisa thinks back to the training camp she held with Ryuumonbuchi, Kazekoshi, and Tsuruga. During the camp, Touka unconsciously enters a 'cold state' where she manages to beat Saki, Koromo, and Fujita. Later, Hisa invites Nodoka and Yuuki's friends from middle school, Maho Yumeno and Hiroko Muruhashi, to play with Saki and Nodoka, where Maho shows a fearsome ability.

As everyone besides Saki get together to watch the Side A semi-finals match, in which her old upperclassman from middle school is participating, Nodoka is surprised to find Achiga, whose mahjong club she used to be a part of, is participating in the match as well. She and Yuki head to the auditorium to watch their match, but Saki finds herself unable to join them, as knowing her sister is there trigger some traumatic flashbacks for her. Unable to get into the main hall, Nodoka and Yuki are given the opportunity to watch the match in the press room. She soon comes across Achiga's team, with Nodoka and her old friend Shizuno stating their determination to meet each other in the finals. As Saki returns to her inn, where she is visited by Koromo and Hajime, Nodoka is interviewed by the press about how she came to know the Achiga girls. Afterward, Nodoka and Yuki deliver some tacos to Kirame, who uses them to comfort the other Shindouji players following their loss in the semi-finals.
