第 17 集: 心跳不已！偶像們的游泳大會！！

17

Kirari attends the idol swimming competition with Erina, Ships, and Arashi, but she is not very competitive at these sporting events, making winning a very challenging task for her team. Erina, who fares worse, refuses to go into the water as water will only destroy her appearance. As the competition goes on, Erina's shortcut to protect herself from contact with water only makes their team lose. (Source: Wikipedia)
