Chihiro's the childhood playmate and vassal of Aritsune. He's also in his second year of high school. He strictly educates Aritsune who even though is the head of the clan but is really clueless about himself. Even though his piercing attitude towards Aritsune makes people really suspicious about their master servant relationship, but the both of them have a deep trust and compadre for each other. (Aritsune even calls him [Chika].) Outstanding results in school, has good manners and treats people kindly, he’s really popular with the teachers and female students. (From wasabisenbei aka cheezy)
