Caren

As the Antarctic Ocean's Mermaid Princess and guardian of the Purple Pearl, this powerful figure possesses three distinct forms, including a talented singer persona. Driven by a deep resentment toward Rina, she initially seeks to rescue her captured sister, Noel, entirely on her own. Although she starts as a strict and somewhat cold loner, she eventually becomes a vital ally to the main trio. Over time, her prickly exterior melts into a playful, energetic personality that helps protect her friends.
