Mayo Chiki! Vol. 3 (Omnibus)
Kinjiro Sakamachi is a "normal" 17-year-old boy who happens to suffer from an abnormal fear of women, otherwise known as gynophobia. His phobia, which surfaces as an occassional nosebleed, has been kept more or less under control - until now. A fateful visit to the school bathroom turns Kinjiro's world upside down, as he discovers the dashing and popular Konoe Subaru is actually a girl! What's worse, the principal's cruel and domineering daughter, Kanade Suzutsuki, has every reason to keep this secret from leaking out, and makes it her life's work to torment Kinjiro, while attempting to cure his gynophobia. Collects volumes 6 and 7.
