Sisters

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.
