橘 鈴魚

She is the younger sister of and successor to Aina, the current mermaid princess.

On the surface, she is a bit of a brat, but in reality, she is a kind and caring girl.
Actually, she is surprisingly whiny and spoiled.

She can do anything she puts her mind to, and she is willing to work hard.
She is also the type who hates showing her efforts to others.
