Princess Knight

Once known as a skilled fencer who had masqueraded as a prince in order to succeed her late father, Sapphire is now happily married to her love Franz and queen of their combined realm. After she gives birth to twins, a boy and a girl who are now equal in the royal line of succession, however, a dispute arises among the courtiers and populace over which child is the true heir. When a whimsical cherub with a familiar face is unwisely summoned to settle the matter, he allows sheer luck to rule in favor of the boy. Yet once Prince Daisy is whisked away by a cabal opposed to his ascension, the remaining Princess Violetta must embark on the same path her mother once tread to safeguard her family’s claim to the throne. Cross-dressing is hardly the end of it as she undertakes breathless adventures with a gypsy lass she meets—Emerald! (Source: Kodansha USA)

A remake of the original Princess Knight, and the much more well-known version of the story. Taking place in a medieval fairy-tale setting, Princess Knight is the story of young Princess Sapphire who must pretend to be a male prince so she can inherit the throne (as women are not eligible to do so). This deception begins as soon as she is born, as her father the King announces his baby is a boy instead of a girl. The reason for this is that the next-in-line to the throne, Duke Duralumon, is an evil man who would repress the people if he were to become king, and because of this the King will go to any length to prevent him from taking over.

Sapphire was supposed to be a tomboyish junior high school girl who's not interested in boys, but it all changed on her 14th birthday. Not only did she find out that she's prince Sapphire, the Ribbon Knight, but she also has to protect a country called Silver Land!?
