Autor

A somewhat snobbish music student at the Academy who is obsessed with Drosselmeyer and his powers. After realizing Fakir is a descendant of Drosselmeyer, he becomes very interested in Fakir and encourages him to use the writing abilities Drosselmeyer once used to control the world. At one point in the anime, Rue seduces Autor in order to feed his heart to her father. However, Autor professes his love for her, which casts doubt on her father's words that no one but he and the prince could love her. Conflicted, Rue lets Autor go. Autor does not appear in the manga.
