Princess Sapphire is a princess who was born with a boy's mind and raised as one because of one mischievous angel's mistake. Nevertheless, there is no way a girl can take the throne so her parents and the maid that helped raised her kept it a secret from everyone. Now as a Knight of Ribbon she has to fight to avoid having her identity revealed that Sapphire is a girl. She'll need the help of an angel who is in fact a make-believe angel.
宝马王子。《缎带骑士》：关于本片的翻译、配音、及其他。歪评：奈特王子的战绩。漫谈《缎带骑士》宝冢剧（手冢治虫）（动漫札记）。都没有人写评论吗？。一位公主不应该只有做王妃一种结局。蓝宝石公主吧。。
