Ahiru, a sweet and gentle protagonist, may seem an unlikely hero in a real-life fairy tale. However, she is just as magical as the talking cats and crocodiles in her town, for she is actually a duck, transformed into a human girl by the eccentric Drosselmeyer. With the aid of her egg-shaped pendant, Ahiru transforms into Princess Tutu, a graceful ballet dancer who has the power to ease the emotional pain of others. Her mission is to gather the shattered pieces of her prince's heart, which he broke long ago to seal away an evil raven. The story of Princess Tutu is a tale of heroes fighting against destiny, and their beliefs, emotions, and actions will determine whether they will reach their "happily ever after." There are 38 episodes of Princess Tutu, with the first part consisting of 13 episodes that are 25 minutes long and the second part consisting of 24 episodes that are 12 minutes long, with a 25-minute finale.
