Princess Tutu (プリンセスチュチュ Purinsesu Chuchu) is a metafictional, ballet-themed magical girl, dramatic- anime television series broadcast in Japan, the first season in 2002 and the second in 2004. The characters are from the TV series and a manga series derived from the anime television series.
Princess Tutu follows Duck (Ahiru in the original anime and manga, meaning "duck"), a duck who was transformed into a young girl and takes ballet at a private school. She becomes enamoured of her mysterious schoolmate Mytho, and transforms into a Swan-like ballerina—Princess Tutu—to restore his shattered heart. Mytho's girlfriend Rue transforms into Princess Kraehe to frustrate Tutu's efforts, and Mytho's protective friend Fakir discourages Mytho's burgeoning emotions. When it becomes apparent that Duck, Rue, Mytho, and Fakir are meant to play out the characters in a story by a long-dead writer named Drosselmeyer, they resist their assigned fates and fight to keep the story from becoming a tragedy.
