reiuji utsuho (bird)
The raven form of Reiuji Utsuho. Usually has her green hair bow on top of her head, and may or may not be wearing her starry white cape with the Yatagarasu's eye on her chest. Has a decent chance of looking like a bird-like sphere.
Pixiv calls "Hiyoko Manjuu-like Utsuho"~originally created by Kyako Youkan~ "おキューちゃん (Okyuu-chan)" and distinguishes her from others.
"Okyuu" is a pun for "Okuu" and "kyuukan-chou (the Common Hill Myna)."
