Haruka and the other club members decide to hold a training camp to prepare for prefectural.  Each member follows his own regimen.  However, Rei is unhappy about falling behind and heads back into the ocean at night to practice.
So it's just a coincidence.
Also ist es nur Zufall.
Si es una casualidad, 
está bien que sea así.
Aunque perfecto si es una casualidad.
Si c’est une coïncidence, 
ce n’est pas grave !
Se è una coincidenza
 non ci dobbiamo fare problemi.
Então é apenas uma coincidência.
Значит, это просто совпадение.
