Sayo is a petite girl with an average height. She has shoulder-length, dark, red hair. She has tattoos on her body to seal her immense power.
She is very caring towards others and openly shows her affections for Rokuro. She even offers to give her own life for others such as when she was kidnapped. Since she was confined in her house for most of her life, she shows interest in the outside world.
Arima Tsuchimikado sends Sayo with Shimon Ikaruga to act as the proctor for Rokuro Enmado. Two years ago, she was told that she would meet Rokuro and that her love for him would develop. Upon arrival, she makes Rokuro go shopping with her. She then unleashes Kuzunoha and brings out Rokuro's guardian. The following day, her escorts are murdered by Hijirimaru. She gets abducted and is severely injured by the Basara. She unleashes Kuzunoha in Magano to summon Benio Adashino's guardian spirit, which turns out to be Kuzunoha's enemy, Ashiya Doman. She is rescued by the latter and leaves the mainland stating that she would wait for Rokuro.
