Saki

Nodoka Haramura, Yuuki Kataoka, and Saki Miyanaga go back to the baths to see a shooting star. After Saki leaves to go get some milk, Nodoka and Yuuki begin discussing various things like how the began playing mahjong. Things start to take a turn as Yuuki begins sexually harrassing Nodoka. This situation makes Nodoka accidentally reveal that she is falling in love with Saki.

Miharu Yoshitome recounts her first days in Kazekoshi's mahjong club. She had to work hard to get into Kazekoshi and join the mahjong club. When the first years were having a competition, she met Kana Ikeda and greatly admired her. Later during a match, Mihoko Fukuji notices that something is wrong with Miharu's eyesight.

Tomoki tells Koromo how Touka recruited her to the Ryuumonbuchi team. Two years prior to the current story line, Touka was looking for recruits to join the mahjong team. Hagiyoshi then suggests a "RTS" online player to fill in the last spot. Touka says that she must play against this person to gauge her strength and spends days online in order to verse her.

The other schools who will compete with Kyosumi in the nationals are selected. Among them are Miyamori, Eisui All-Girls, Himematsu, and Rinkai All-Girls, along Shiraitodai and Achiga. As all the representatives arrive for the National tournament, the first day is dedicated for all the teams to settle themselves at Tokyo, as Saki and her friends spend some downtime with members of both Kazekoshi and Ryuumonbuchi. Despite not taking part in the tournament, the girls from Tsuruga also arrive to watch it as well. At the tournament lottery draw, a lost Saki has a short encounter with the Achiga girls before reuniting with her team mates. Kiyosumi draws a bracket in line with both Himematsu and Eisui. Per the schedule, Kiyosumi does not play until day 3 and Hisa declares that they will spend the second day leisurely in preparation for their first match.

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.

Nodoka recalls how she met Yuuki in Takatoobara Middle School and joined its mahjong club, where she also met Maho. Back at the training camp, Maho uses her ability to mimic other people's playstyles and shocks Saki when she copies her rinshan kaihou. Maho ultimately loses the rest of her hands though, as she can only mimic a certain ability once per match and her base skills are poor. It is shown that Hisa had invited Maho to the camp to both improve Mako's repertoire and give Saki a much-needed sense of fear, whilst she herself trains with Koromo, Yumi, and Mihoko. Returning to the present, Kiyosumi makes it through the first round after Hisa's victory, along with Himematsu. A few days later, Kiyosumi faces their second-round match with Yuuki going up against Eisui's Komaki Jindai, Miyamori's Shiromi Hosegawa, and Himematsu's Suzu Ueshige.
