A swordswoman who has a Dog God (Inugami) living inside her, and as a result, is despised by humans.
She saved Tokidoki from the nue. At first, she hates optimistic and naive people like Tokidoki, but she warms up to him throughout the course of the series. She usually wears her hair in a long ponytail, and has a big appetite. She and Kon are friends who love to hate each other.
When she was a child, her grandfather named her Kuchiha, which means "faded flowers", in hopes that she would be the last of the family. After her grandfather's death, she became unable to tend to herself, and lived alone in the shack where she once lived with her grandfather. It is here that she is discovered by Kanzou, a boy with fang marks on his face. Kuchiha lost the ability to speak, but Kanzou understood her and tended to her needs. One day, he set off to find a place where she would belong, and told her to wait where she was. However, she walked away from where she was supposed to wait, getting lost, and losing Kanzou, who was no longer able to find her. She was taken in by the monk Shamon and learned to talk again. Years later, Kanzou finds her again, explaining that their destinies are bound together, for she is the dog god, and he is the destined servant of the dog god, Shirachigo (Gazu Hyakki Yakou). Kuchiha, believing that Kanzou abandoned her, refuses to go along with him at first, but she concedes, leaving Toki with these words: "I'm not like you."
Recently in the series, she saves Tokidoki from the vortex by fighting the monster and cutting her hair after it got a grip of her. Rikugou jumps in after her, confessing his love and getting bitten in the neck. Kuchiha is stuck in the vortex, with a concerned Tokidoki and Kanzou. Her age is unknown.
