Edel

エデル

Edel is a puppet crafted by Drosselmeyer, serving as a guide to ensure all characters follow the intended storyline. She is merely a doll incapable of feeling; however, in a gesture of kindness to portray human emotions, she acts as a martyr by burning her body to keep Fakir warm and light the way to the surface for Princess Tutu and Prince Myuuto. In the end, what remains of her is put back together, and Uzura is born as a reincarnation.
The song Edel plays on her organ grinder is "Musique des Automates" from the ballet "Coppélia". In the ballet, dolls and puppets created by an old toy maker dance to this song, reminiscent of the fact that Edel is a puppet.
In the manga:
Edel is not a puppet, but the owner of a shop that sells tutus. She was the one who gave Ahiru the pendant to transfer into Princess Tutu. Sometimes, Ahiru goes to visit the shop to ask Edel questions.
