Rue

Rue is an advanced ballet student and greatly admired. She remains aloof from her peers, however, and appears to have no friends until Duck brazenly approaches her without fear and they become friendly. She is proud, but has a good heart and struggles with what she must do as Princess Kraehe. She has loved Mytho since she was a child after he defended her from ravens. She uses his lack of emotions to pretend they are a couple. Like Duck, she also has a magical princess alter ego, Princess Kraehe, the daughter of the Raven. Her father is verbally and emotionally abusive towards her, tearing her down to keep control of her. At first, she tries to prevent the prince from retaining his heart shards out of fear she will lose him to someone else. Towards the end of the series, she learns that she is not a raven, but a human girl who was stolen from her parents as a baby during the Raven's attack on the town. She realizes her father has been using her, and begs Princess Tutu not to return the last shard, now fearing Mytho will be consumed by the Raven. Princess Tutu obeys the prince's request, however, and when it appears Mytho will give himself to the Raven, Rue sacrifices herself instead, stating that she had always loved Mytho. Touched by her act, Mytho regains his heart and rescues her, asking her to be his princess. In the manga, Rue's name is Rue Kuroha, and she is a much colder and crueler character.
