Kanokon Esuii

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 the 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 has a fear of swimming. At his school, everyone either calls him the "Great Erotic King" 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. One demonstration 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 transforms into a black-furred five-tailed fox spirit.
