Rina is the Mermaid Princess of the North Atlantic Ocean and the keeper of the Green Pearl. She is the third mermaid to appear in the series and part of the main trio with Lucia and Hanon, appearing throughout the series. Initially portrayed as beautiful but stern, she seeks revenge for her best friend Noel's capture. However, she evolves into a mature character who acts as an older sister figure to Lucia and Hanon. Rina has a notable fondness for plasma TVs and comedy shows, often showcasing this interest in various episodes.
When Gaito attacked her kingdom, Rina escaped with Noel, another mermaid princess. During their search for other mermaids, Gaito and Yuuri appeared and launched an attack intended for both. Noel sacrificed herself to save Rina, who then went to the human world to find Gaito and avenge Noel. Rina enrolled in the same school as Lucia and Hanon but chose to wear the male uniform. Initially, she seemed to dislike Kaito because he resembled Gaito, but she later became friends with Lucia and Hanon after they discovered her true identity.
In the first season, Rina does not have a love interest, but in Pure, she meets Hamasaki Masahiro, and they fall in love. Rina has three forms: Mermaid Rina, Touin Rina (her human form), and her idol form, Green Pearl Voice. Her two image songs are "Star Jewel" and "Piece of Love."
