Kyou is a perverted but powerful Tengu with black wings. Kyou met Misao during their childhood. His older brother, Sojo, was supposed to be clan leader, but Kyou surpassed him for Misao's sake (as only a clan leader may seek her as their bride). In order to stay close to Misao, he moved back to his house next door to her's and took a job as a math teacher at her school. He is always protecting her and healing her wounds. In his demon form, his hair grows longer and he wears a mask that looks like a crow's beak. Kyou took Taro under his wings to train him and make him stronger after Taro was abused by Sojo. He is about 20 years old.
