All the schools gather for the training camp where Yumi gives Hisa some data on the other opponents in the nationals. Later on, nearly everyone takes an interest in ping pong while Mako and some others fail to get revenge on Kaori's beginner's luck. The next morning, some of the girls go in the onsen to discuss the powerhouses of the nationals, including Saki's sister, Teru. Hisa's suspicion of Saki as Teru's younger sibling was confirmed by Saki's reaction when she confronted her of this fact. Saki is a bit shocked to hear from Mohoko that Teru had denied having a sister, so Nodoka decides to take her to a shrine to cheer her up. Afterwards, they exchange souvenirs and decide to call each other by their given names. After they get back, the training starts in a room where the players from Kiyosumi, Ryūmonbuchi, Kazekoshi, and Tsuruga are already seated and ready to play, with Hisa also having invited Fujita to join them. Kiyosumi prepare themselves for the nationals.
