Homare finds the solitary island where Shion washed ashore and the two are reunited. But there's no time to rejoice. With no food or water, succumbing to dehydration is only a matter of time... All they have is filthy water they find in a cave... In this dire situation, the two of them use a secret technique for rehydration!? Will Homare and Shion make it back to the island?
At this rate, both of us will start suffering
from dehydration on the way back.
سنعاني من الجفاف معاً في طريق عودتنا
على هذا النحو
A este paso, ambas sufriremos
de deshidratación al regresar.
A este paso, ambas sufriremos
de deshidratación al volver.
Ça va être compliqué de rentrer,
si on est déshydratées.
Di questo passo, finiremo per disidratarci entrambe
sulla via del ritorno.
Desse jeito, nós duas vamos sofrer
com a desidratação na volta.
На обратном пути 
мы обе начнём страдать от жажды.
