In this story, Princess Sapphire was raised as a prince due to a mistake by an angel that gave her both female and male characteristics. Since there was no male successor in her kingdom, she was trained as a boy. However, corrupt officials tried to expose her secret. Unable to tolerate the harmful behavior in her kingdom, Sapphire disguised herself as "Princess Knight" and used her sword of justice to fight for what was right. This animated series follows the romance and adventure of Princess Sapphire, which was the first made-for-TV program aimed at girls in Japan.
