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
I want to swim in a relay
Ich will in einer Staffel schwimmen,
Quiero nadar en el relevo con ustedes, 
con los mejores compañeros...
Quiero nadar este relevo con vosotros, con los 
mejores compañeros que un nadador puede tener.
Je veux nager avec vous tous…
È insieme a tutti voi,
Eu quero nadar um revezamento
Я хочу проплыть в эстафете
