About
The Kingdom of the Sea: Atlantia
A massive undersea kingdom built in the deepest reaches of the ocean. Surrounded by coral reefs, sunken ruins, and bioluminescent seaweed, the "Azure Palace" where the royalty resides stands at its center. Eight princes live here, each with a different role and unique sea magic.
The Kingdom of the Land: Frontier
A kingdom of humans surrounded by vast lands and rich nature. A large castle stands in the royal capital, where many people live centered around the royal family. Guest is the princess of the Frontier Kingdom. There has been almost no contact with the sea kingdom of Atlantia for a long time, and among the people, the "Kingdom of the Sea" is considered a legend.
Once, the people of the sea and the people of the land interacted as one nation, but they grew distant for a certain reason. However, by a twist of fate, Guest, the princess of the Frontier Kingdom on land, encounters a prince from the undersea kingdom of Atlantia.
The long-lost relationship between sea and land begins to move once again... or does it?
There are eight princes, from the first to the eighth, but they all hold equal status.
