Sylphiel's only known family is her father, Elc, who was a priest in Sairaag, and her uncle, whom she lived with after Sairaag was destroyed by Copy Rezo. Elc was killed when Copy Rezo destroyed most of the city; he was later resurrected by Hellmaster Fibrizo, only to be killed again when Fibrizo was destroyed by the Lord of Nightmares. There is no mention of her mother in the novels, manga, or anime.
