Fakir

ふぁきあ

Fakir serves as the Knight in the story, spending his life watching over Myuuto to protect the Prince as planned. He acts deliberately cold and rude near the start of the series to focus entirely on Myuuto, and also attempts to sabotage Princess Tutu to return the Prince's heart pieces. Although this was all intended to shield his friend from the story's normal progression, specifically Myuuto's wish to regain his heart, his attitude changes.
His role in the tale is very clear: the Knight is supposed to confront the terrible Raven to guard the Prince; however, he is meant to die without striking the monster. Fakir sets out to prove to himself that the ending need not be so, and consequently, he is unsure of his purpose afterwards.
