Haruka moves on to Iwatobi Junior High School  with Makoto and starts a new life. Both enter the swim team, and plan to compete in the medley relay together with Asahi Shiina and Ikuya Kirishima. All four students have different objectives and ways of thinking, and different baggage they're carrying, and so their practice for the relay hasn't been going well. What is required to make a team?
