Silvia de Alisia (シルヴィア・ド・アリシア Shiruvia do Arishia?)
Voiced by: Yumi Kakazu (Japanese), Brina Palencia (English)
The female protagonist, she is a noble from the Alisia family and the reincarnation of Apollonius' human lover Celiane. Silvia possesses great physical strength and admiration for her older brother Sirius, who she believes he is the real reincarnation of the "Solar Wing". She constantly argues with Apollo, not only because she thinks he is an impostor, but because of his rude habits and untamed nature. Her main power as an Element is her psychokinesis, and later is revealed to be a descendant of Apolloius and Celiane, thus being a Shadow Angel/Human hybrid possessing some of the powers of a Shadow Angel.
For much of the series, Silvia hangs off her brother and attempts to sabotage his relationships. As the story progresses, it is revealed she carries the "light" half of Celiane's reincarnated soul (the part that remembered what happened in her previous life). It is this part of Celiane that Silvia feels affectionate for Apollo. She bids farewell to him as he decides to save the world through self-sacrifice, promising to look after his homeless friends and await his return 12,000 years later.
