Shion has been swept away by a rip current and the others are at a loss. That's when Homare decides to build a new raft and go after her! She breaks her fathers rule of "you own life comes first," risking her life to go save Shion, but in the vast ocean, Homare can't find her... Having exhausted every option she can think of, suddenly Homare remembers one of her father's teachings...!
If the sun sets, I won't
be able to look any more.
إن غربت الشمس لن أتمكن من البحث أكثر
Sobald die Sonne untergeht,
ist eine weitere Suche zwecklos.
No podré seguir buscando
en cuanto se ponga el sol.
No podré seguir buscando
en cuanto se ponga el sol.
Dès que le soleil se couchera,
je devrai rentrer.
Di questo passo, giungerà il tramonto
e non potrò proseguire le ricerche.
Se ficar noite, não conseguirei mais ver...
Когда солнце сядет, 
видимость упадёт до нуля.
