Rys, フェンリース

Fenrya, also called Rys, is a demon who takes on the appearance of a white/silver Fang Wolf in her demon form and has long white/silver hair and blue eyes in her human form. She wears a dress that matches her hair color. She deceived Flio and had him escort her towards the Delaveza Forest. During the journey, she attacked him but was defeated by his powerful magic. After transforming back into her human form, she announced that she would no longer attack humans and would become Flio's wife in exchange for his protection.
