The Iwatobi Swim Club needs one more member before it can participate in relays.  Nagisa has set his sights on his classmate Rei, who is a member of the track team.  Despite Rei's refusal to join, but Nagisa appears intent on recruiting Rei into the swim club.
Then we can do relays again.
Dann können wir 
wieder Staffeln schwimmen.
Y volvamos a hacer relevos.
Y hacer relevos de nuevo.
Et faisons à nouveau un relais !
E facciamo ancora una staffetta!
Daí podemos praticar revezamento.
И тогда снова поборемся.
