Rein

レイン

Rein serves as the series' second protagonist and is the other twin princess of the Sunny Kingdom. While she may appear identical to her sister, Fine, her eyes are sea-green and her hair is blue and significantly longer than Fine's. Rein is also described as one of "the most unprincess-like princesses in the history of Fushigi-boshi", yet unlike Fine, she enjoys dressing up and wearing elaborate decorations. She becomes obsessed with romance and always appends "-sama" to Bright's name. Rein is adventurous, but equally friendly, eccentric, and caring as Fine. She frequently thinks of positive ways to resolve issues and behaves more femininely than Fine. Her name was originally spelled with an "a" in English, but the director, Junichi Sato, did not want her name to be associated with the weather term "rain".
