The In-oe that Otogiri Tobi carries around. It is intelligent and can speak. It has a very mischievous personality. Its form is a black backpack worn on the back.

A girl born as a reincarnation after a dragon died. She has two horns on her head. Otogiri Tobi takes care of her like an older brother. She acts like a stubborn child, but considering she was once a dragon, she is like a deity who has lived for hundreds of years. She has long, light blue hair with red secret two-tone coloring underneath. She hates wearing tight clothes, so she wears Otogiri Tobi's shirts like a dress. She is clumsy at expressing emotions, but she gets annoyed easily. A stubborn young girl.
