Hana-Kimi: For You in Full Blossom, Vol. 7

AMERICAN GIRL
Julia is Mizuki's girlfriend?! As the shocking lie tears Osaka High School apart, Mizuki's classmates make their moves on the blonde, blue-eyed transfer student. Then the whole class leaves on a school trip to Hokkaido, complete with an overnight stay at the hot springs! With their "chaperone" Dr. Umeda busy getting to knowing the locals, it isn't long before people start taking off their clothes (to bathe, all right?). But how long can Mizuki's gender stay secret inside the boy's bath?
