Caren is the Mermaid Princess of the Antarctic Ocean and the keeper of the Purple Pearl. She is the fourth mermaid to appear in the series.
Like Hanon and Rina, Caren also escaped to the human world when Gaito attacked her kingdom. However, even though she is discovered by the trio, she refuses to join them initially. She shows hatred towards Rina because Caren is the younger sister of Noel, who was captured by Gaito. Caren heard that Rina was with Noel at that time and believed that Rina left Noel behind. (In reality, Noel sacrificed herself to save Rina.) Therefore, Caren resolves to save Noel on her own.
Over time, Caren saves the trio on various occasions, especially when the Black Beauty Sisters are introduced. Near the end of the first season, Caren joins forces with the trio as they prepare for the final battle against Gaito.
After Gaito's defeat, Caren leaves to help rebuild her kingdom. Later, she returns to the human world with Noel and Coco, and they become comic relief. Caren also returns to fight against Michel.
Initially, Caren is strict and even a bit mean, but she gradually warms up to the trio and reveals her playful side. In Pure, Caren is energetic and playful, unlike in the manga where her personality was not fully explored.
Caren has three different forms: Mermaid Caren, Human Caren, and her singer form, Purple Pearl Voice. Her image song is "Aurora no Kaze ni Notte."
