Hana-Kimi: For You in Full Blossom, Vol. 4

CLOTHES MAKE THE MAN
All-male Osaka High School is holding its annual war of the dorms, and for the students, there's no escape! Unfortunately, even though she'd be happy to just compete in the 500-meter relay, Mizuki is forced to enter the Cross-Dressing Pageant...and pretend to be a boy pretending to be a girl! Worse still, a rival dorm targets Mizuki as a threat to their athletic supremacy! Can dorm chief Minami Nanba make winners out of his class while dealing with his own secret traumas?
Plus a bonus story, "The Thirsty Moon"!
