The girls in the Breakwater Club learn how to float properly just in case they ever fall into the ocean. Later on, Hina goes to battle with a heron, but then notices it has a fishing line tangled around its leg.
If you sleep, you'll die,
so please don't copy her.
.ستمُتن إذا نمتن، لا تقلدنها
Macht das nicht nach, das ist euer Tod.
Si se duermen, morirán,
así que no la imiten.
N’essayez surtout pas de l’imiter.
Se dormir, você morre.
Não imitem, por favor.
