When Subaru goes to her local observatory to prepare for an upcoming meteor shower, she ends up seeing far more of the stars than she expected. Instead of a simulated viewing of astronomical phenomena, she gets recruited to take part in a fantastic adventure with a mysterious young man, a bizarre alien creature, and a group of girls dressed in cute, magical garb. Together with the other girls (who are suddenly and strangely members of Subaru's school), Subaru becomes part of a clandestine effort to retrieve fragments of an alien spaceship! However, the fragments are being scattered all over the universe. Time is limited, and the girls face a nemesis who is seeking to gather all the parts for himself!
