reiuji utsuho (bird)
The raven form of Reiuji Utsuho. May or may not have the Yatagarasu's eye on its chest.
Pixiv calls "Hiyoko Manjuu-like Utsuho"~originally created by Kyako Youkan~ "おキューちゃん (Okyuu-chan)" and distinguishes it from others.
"Okyuu" is a pun for "Okuu" and "kyuukan-chou (the Common Hill Myna)."
