Fine  

, ファイン

One of the twin princesses of Sunny Kingdom, Fine has red eyes and reddish-pink hair. She is often referred to as one of "the least princess-like princesses in Fushigi-boshi's history." Despite being athletic and gluttonous, she struggles with dancing like her sister, Rein. However, Fine is known for being friendly, kind, and caring towards those she loves, including Shade. She tends to be slow in thinking compared to others but was the first to realize that Eclipse (Shade) wasn't as bad as everyone thought he was, leading her to fall in love with him. Additionally, Fine can understand Milky because they both share a love for food. While she usually does what is best without hesitation, Rein often stops her from making hasty decisions.
