What happens when the hottest guy in school is a girl?!?

The Prettiest Boy In School...Isn't A Boy!Japanese-American track-and-field star Mizuki has transferred to a high school in Japan...but not just any school! To be close to her idol, high jumper Izumi Sano, she's going to an all-guys' high school...and disguising herself as a boy! But as fate would have it, they're more than classmates...they're roommates! Now, Mizuki must keep her secret in the classroom, the locker room, and her own bedroom. And her classmates--and the school nurse--must cope with a new transfer student who may make them question their own orientation...

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 know 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?
