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...

"Girls" and Ghosts!

Mizuki and her friends go to the country, where they meet and try to help a ghost pining for his lost love. Then, for the big Christmas dance party, Mizuki and Nakao are recruited to help make up for a shortage of girls--by dressing up as girls! This turnabout for Mizuki, however, proves to be the least of the complications that flare up when the whole ploy proves too successful!
