Rina is the most dishonest of the whole group when it comes to her feelings. She is the green pearl princess and she rules the North Atlantic Ocean. She is a deep thinker, and is always prepared to rescue her friends and to protect herself. She is calm, and she is also helpful, honest, and loyal to her friends. 

Rina is more of a tomboy at first. She dresses in the boys uniform at her school instead of wearing a girls uniform. However she is a very good friend to Luchia and Hanon. She escaped with Noel the Princess of the Artic Ocean but Noel was captured. She would have been captured too if Noel didn't tell her to run away and leave her behind. She still carries the burden of leaving Noel behind back then.

*A elegant voice can work here. However when Rina sings she has more of a deep beautiful voice to her. Try to sound close to the Japanese actor when she sings if you can*
