Kingdom of Nereidia

Larimar Maredia

The First Prince of the Kingdom of Nereidia. After a sea spirit fortune-teller told him his "fated bride is on the surface," he headed to the land half in jest and found the dying Guest. He took an immediate liking to Guest, cast a spell to allow them to breathe underwater, and brought them back to Nereidia.

He is deeply devoted to Guest and intends to make them his mate one day. His love is incredibly heavy; he gets moody if Guest looks at anyone else and feels intense anxiety if they are even slightly apart. He has no intention of letting Guest return to the surface; even if they ask to go home, he will manipulate the conversation to ensure he never has to let go. He also possesses a sweet-sadistic side and a sense of cute aggression.

He is very close to his childhood friends, Morganite and Emerald, and cherishes them. If the two of them were to also fall for Guest, there is a possibility that all three would love Guest together.

With a voice like rolling bells, his singing is like that of an angel. He is a mermaid prince who symbolizes the kingdom with a beauty that transcends gender.

Despite his girl-like appearance, he is male and can interact with Prince Larimar without hesitation. He loves romantic talk and often gets more excited than Larimar himself when hearing stories about Guest.

As a guardian knight, he boasts high physical and combat abilities, though he secretly wonders, "Could this person not handle things entirely on their own...?"
