Yuzuriha is attended by her own personal inugami, Inuki (犬鬼), who can shapeshift into anything she desires and who can only be seen by others with occult powers. She was teased throughout much of her childhood as her classmates believed Inuki was her imaginary friend. Because of this, Yuzuriha made a vow that she would never fall in love with (or even date) a man who could not see Inuki. However, the first person outside of her family that she meets who can see Inuki is Kusanagi Shiyū—a Dragon of Earth. Yuzuriha falls in love with Kusanagi, regardless of their conflicting fates.
