Japanese-American track-and-field star Mizuki is transferring to a high school in Japan... but not just any high 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 weird school nurse, must react to the new transfer student who looks like a very pretty boy...
