カミュ

The second princess of Onkamiyamukai, and also the younger sister of Urutorii. She befriends Aruruu and Yuzuha and is often seen playing with them. Previously, she had no friends (apart from her sister) and everyone in the mediators considered her to be a monster because she was born with black wings.[From Wikipedia]Her black wings are a sign that she has inherited Mutsumi, who lives within her like a split personality.
