Fine is the one of the twin princesses of Sunny Kingdom. She has red eyes and reddish-pink hair. Fine is referred to as one of "the most unprincess-like princesses in the history of Fushigi-boshi". She frequently whines whenever she sees or hears anything supernatural. Fine may be athletic, but also gluttonous. Just like her sister, Rein, she is not a very good dancer. Nevertheless, she is friendly, kind, and cares about the people she loves (including Shade). Fine is always slow on what others are thinking. She was the first one to find out that Eclipse (Shade) wasn't as bad as everyone thought he was (which soon leads her to fall in love with him). Fine can understand what Shade's little sister, Milky, is saying because they both like to eat. Fine usually do what's best for her without thinking, but Rein stops her.
