The granddaughter of the director of the Onmyo Prep School and heir to the Kurahashi family. She is part of the top students in the school and one of only 3 known students to possess a Gohou-Type shikigami which consists of two Yaksha demon class warriors called Hakuou & Kokfuu.
Initially, she appears antagonistic towards Harutora (and by extension Natsume) due suspicion of using his family's fame and status of being Natsume's shikigami to suddenly enroll directly into the elite academy at mid semester. After a series of events, she reconciles with Harutora establishing a friendship based on common ground. She also reveals two surprising truths; first being, that Kurahashi's were once a branch family of the Tsuchimikado's. Second, she had once visited Tsuchimikado's home as very young child and Kyouko had made a certain promise with Natsume at the at time. But once they had reunited again Natsume treated her like a complete stranger, frustrated at having her feelings trampled, she used Harutora as a pretext to start fights with Natsume. However, ironically in reality, the person she met that day wasn't Natsume, but Harutora who she mistook as Natsume. After helping Harutora save Natsume from a Yakou Disciple the two make up. This later causes her to admit to Harutora that she is in love with Natsume, being oblivious to the fact that she is a girl. Kyouko now plans to further her relationship with Natsume and forces a reluctant Harutora to help her as payment for the Yakou Disciple incident.
