『Filvis Challia』

Filvis Challia(フィルヴィス・シャリア) was the captain of the Dionysus Familia. She is later revealed to be the Creature Ein(エイン) who was working under Enyo.

Filvis had long black hair and red eyes. She wore a frilled white dress with a white coat with light blue edges over it. As Ein she wore a long purple robe that covers most of her body except for her face, over which she wears a pink and purple mask with an eerie design.

After she cancelled her duplication magic and became one again, her black hair grew long enough that it touched the ground and her eyes turned dark blue. The area around her eyes sank in, pale red root like things grew out of the magic stone in her chest, and her skin turned an unhealthy bluish white color.

Like most Elves, Filvis didn't allow anyone other than those she allowed to touch her, which included other Elves. However, her attitude toward Elves was later revealed to be because she didn't want to dirty them, as she thought she was unclean.

As Ein, she is extremely loyal to Enyo, accusing Revis of betrayal just because she didn't move when she told her to. When acting as Ein she uses the mask to create a voice that sounds like multiple people speaking at once and sounds similar to a man and a woman.
