Thanks to a freak accident with an alien space ship, Hazumu has had to get used to living life as a girl instead of a boy. Not only that, her relationship with childhood friend Tomari and first love Yasuma has somehow developed into a delicately balanced seesaw of a love triangle! But now a wrench has been thrown into the works: the alien that caused this mess has just informed Hazumu that she only has 30 days left to live. Only by merging her fate with that of another does Hazumu stand any chance of surviving!
