Story
When you've got acute gynophobia, even a pretty girl can be a malady, and as the sparring partner for his family of female wrestlers, Sakamachi Kinjiro has the worst case EVER! Just one touch makes his nose bleed, so school's a bloody nightmare even before Kanade, the Principal's twisted daughter, deduces both Kinjiro's "feminine issue" AND that his name contains the sounds "Chi" and "Kin" back to back. But Chi-Kin's female troubles don't totally redline until a wrong turn in the men's room exposes the secret Subaru, Kanade's manservant, has been hiding in the water closet.
