Character Setting

Edit

Ferdinand is the head priest of the temple and serves as Myne’s guardian. He is famous for his good looks—blue hair and light golden eyes—but often looks serious and older than he is. Ferdinand is skilled in many areas, handling most temple business, and is also noted for being mysterious. Even though he rarely shows his emotions, he deeply cares for Myne and becomes her teacher, teaching her noble manners and skills. He has a complicated past, is wary of the royal family, and is called "Demon Lord" or "Mad Scientist" by Myne. Through many challenges, Ferdinand discovers Myne's true nature, establishes a unique bond with her, and eventually finds the family and love he deeply desired.
