Voiced by: Mamiko Noto (Japanese), Mona Marshall (English)

Kouta is the protagonist of the story. He moves from the country to the city in his first year of high school, and on his first day of school, he discovers that a second-year girl Chizuru Minamoto is actually a kitsune. He used to live with his grandfather before moving. Kouta generally has a mild personality and is indecisive. When he was younger, he almost drowned in a river and now he has a fear of swimming. At his school, everyone either calls him "Great Erotic King" ("King of Eros" in the English anime) or a "beast" because of the disgraceful acts Chizuru commits with him in public.

Despite his reluctance to engage in the "intimate" acts that Chizuru desires, Kouta's feelings for her are genuine. An example of this is that they are able to fuse together 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 transformes into a black-furred five-tailed fox spirit.

In the manga, the reason due to him transforming is because he himself is transforming into a yokai like Chizuru, but also due to the fact Chizuru being the nine-tailed fox which is known to have unlimited source of power, Kouta gained a new power when the tails are on fire. it is said to be from the Eight Dragons, and portion of it has now been passed onto Kouta while the rest resides in chizuru.
