Kouta Oyamada is a first-year high schooler. Before moving to the city, he lived with his grandfather. On his first day of school, he met [Chizuru Minamoto](https://anilist.co/character/10902/Chizuru-Minamoto) and discovered that she was a yokai.

Kouta is short, has brown hair, and silver eyes. He's shy, bears a mild personality, and is indecisive, often with Chizuru and [Nozomu Ezomori](https://anilist.co/character/10900/Nozomu-Ezomori).

Despite his reluctance to engage in the intimate acts Chizuru desires, Kouta bears feelings for her. They're able to fuse into a powerful being, which can only occur between a human and a kitsune when they share a deep emotional link. In this form, Kouta transforms into a black-furred, five-tailed spirit fox.

Due to his relationship and exposure to yokai, he's turned into a yokai - specifically a kitsune.
