The Iwatobi Swim Club must win to advance to nationals. As the tournament draws near, the members get nervous. Meanwhile, Rin grows increasingly irritated. As it comes time for the medley relay, each member must find their own answer as they step up to the start line
Swim to your hearts' content!
Schwimmt nach Herzenslust!
¡Naden como deseen, con libertad, para 
que no tengan nada de qué arrepentirse!
Nadad como os dé la gana, con libertad, 
para que así no os arrepintáis de nada.
Nagez comme vous voulez
Nuotate con il cuore, liberi!
Façam o que quiserem! Sejam ousados!
Плавайте в своё удовольствие.
