These manga are set in Renaissance-style Fantasy realms, with a focus on knights and Nobility, and predominately taking place in castles and courts. A popular type of Otome Game setting, women in beautiful ballgowns (sans crinolines) are everywhere, royalty are getting married off to ensure the flow of money, and there's usually some form of intrigue in the court. These worlds may have developed more "modern" technology than their Medieval counterparts, such as books/printing presses and mass education, or be bolstered by use of Magic.
