Sakamachi Kinjiro suffers from acute gynophobia, making even an attractive girl a source of discomfort for him. This becomes compounded by his role as a sparring partner for his family's female wrestlers. His condition is so severe that even the slightest touch from a girl results in a nosebleed, making school a nightmare. Adding to his troubles is Kanade, the Principal's twisted daughter, who naturally deduces his issue and the fact that his name contains the sounds "Chi" and "Kin" back to back. Things escalate for Chi-Kin when a wrong turn in the men's room exposes Subaru, Kanade's woman servant, who is hiding in the water closet. Subaru's cross-dressing only adds to Kinjiro's fascination with female troubles. The situation becomes even more complicated with the emergence of a haunted martial artist and a cat-eared fetishist. As if that wasn't enough, Kinjiro's own sister becomes interested in "wrestling" with a certain butler who has been incorrectly packaged, leading to an unexpected turn of events. All this is just the set up for a wild ride.
