Kyou is a perverted but powerful Tengu with black wings. Kyo met Misao during their childhood. His older brother, Sojo, was supposed to be clan leader, but Kyo surpassed him for Misao&#039;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&#039;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&#039;s beak. Kyo took Taro under his wings to train him and make him stronger after Taro was abused by Sojo. He is about 20 years old.

There is a world of myth and magic that intersects ours, and only a special few can see it. Misao Harada is one such person, and she wants nothing to do with magical realms. She just wants to have a normal high school life and maybe get a boyfriend. But she is the bride of demon prophecy, and her blood grants incredible powers, her flesh immortality. Now the demon realm is fighting over the right to her hand...or her life!
