In Tokyo, in the not-too-distant future, a young girl looks up to the stars with melancholy in her heart and hope in her eyes. 13-year-old Asumi Kamagawa's whole life had been tied to those stars - her future may very well be among them.

Before lift-off, like any true astronaut, she must show the right talent, drive and skill to overcome the odds and pass numerous physical and mental trials to enrol in the elite space academy.
