The Gentle Wave Sea lies adjacent to the Green Plains, a vast and true ocean.
This ocean encircles the entire continent.
In the eyes of other elemental creatures, the Gentle Wave Sea is nameless, for despite its vastness, capable of surrounding the entire continent, its water system strength is not as vigorous as the other water system areas within the Tidal World.
For such an ordinary sea with sparse water system strength, other elemental creatures simply call it "the sea," and have not bothered to name it specifically.
The Gentle Wave Sea, as named by the gentle wind Uranus, signifies "the peace of the sea, with gentle winds rippling soft waves."
In terms of naming, the Gentle Wave Sea is certainly more beautiful than the Nameless Sea, so Angel, following the naming by the gentle wind Uranus, also refers to it as the Gentle Wave Sea.
