As prefecturals draw near, Haruka and the other swim club members continue to improve.  Meanwhile, Rin reveals his motivations for swimming.  The swimmers must now show what they have accomplished at the tournament.
This is who will do butterfly with Rei-kun.
Die hier werden Schmetterling 
mit Rei-kun schwimmen.
Y las de estilo mariposa, 
como Rei-kun, son estas...
Y los de estilo mariposa, 
como Rei-kun, son estos...
Et celui qui sera en papillon 
face à Rei.
Nello stile farfalla con Rei-kun, questi.
Esses aqui vão nadar borboleta,
 junto com o Rei-kun.
И есть тот, кто поплывёт
баттерфляем с Рэем.
