Wish Upon the Pleiades

Synopsis

Subaru is excited to watch a meteor shower from her school's observatory, but instead finds herself in an opulent garden with a fountain and a mysterious red-haired boy. When the scene fades away, leaving behind a bouncing creature, Subaru steps through a magical portal and meets several girls dressed as witches. Among them is her childhood friend, Aoi. She learns the creature is a Pleiadian alien who needs to return home, and that she has been chosen to help. Subaru's love for astronomy takes an unexpected turn as she and her new witch companions set out to collect the scattered pieces of the alien's spaceship engine. However, they are not the only ones searching, and the motives of their rivals remain unclear.
