Kamyu wears a brown dress with dark blue puffy sleeve with white cuffs and red trimming. Her brown dress is accompanied by two pieces of white cloth with red trimming tied on to the dress by a light blue belt. She wears brown boots that go up right below her knees with white edges. Her hair flows right below her ears and it is silver. She also has black wings (which is unusually for her race because they all have white). Kamyu's eyes are also a rich deep blue.
Kamyu is very playful and sweet. One could easily consider her as a hyperactive teenager due to how energetic and outgoing she is, but can also be found playing games and/or doing activities that do not require much energy, proving that she can care less what she does as long as it's with her friends.The past is a sensitive subject to Kamyu as everyone back home either treated her like a monster due to her having black wings as opposed white ones, or being overly respecting to her because of her status, resulting her not having any friends up until she came to Tuskuru. She is also has shown signs of becoming scared about becoming Mutsumi.
Kamyu is the second princess of Onkamiyamukai, a race of angel-like people who act as priests and peace-keepers for the land, and also the younger sister of Urutori. She befriends Aruruu, Yuzuha, and Mukkuru and is often seen playing with them.
She makes an appearance in Itsuwari no Kamen with Aruruu not only to establish friendship between Yamato and Tuskuru but also to find Kuon. She makes another appearance when Yamato invades Tuskuru, during which Kamyu distracts the rest of the supplies and sends them back to the harbor while Aruruu, with Mukkurru, leads the supplies along with Haku, Kuon, Rulutieh, Atui, Saraana & Uruuru, and Kokopo from Yamato over to their camp.
Urutorii - Her eldest sibling. She is sometimes scolded by her for her mischievous behavior but loves her very much.
Yuzuha - One of her best friends alongside Aruruu.
Kuon - Her younger "sister" that she raised. According to Kuon, Kamyu and Aruruu are the two most overprotective members of her family.
- Kamyu is the incarnation of Mutsumi, whose spirit lived inside of Kamyu before being released by Dii.
