Wish Upon the Pleiades

Subaru, a starry-eyed girl with a passion for astronomy, stumbles upon an unexpected discovery when she enters her school's observation room, only to find it transformed into a lush indoor garden. Here, she encounters Minato, a mysterious boy whose cryptic warnings hint at something extraordinary. Shortly after their brief interaction, Subaru's curiosity leads her to a peculiar, blob-like creature that snatches her compass, ultimately guiding her to a mysterious club room filled with girls donning witch outfits.

Among them is her friend Aoi, who is initially reluctant about Subaru’s involvement. However, drawn by the allure of the unknown, Subaru chooses to join the club, where she soon receives a magical staff and undergoes a stunning transformation, courtesy of the club's leader—the very Pleiadian creature she met earlier. Together with Aoi and their fellow club members Itsuki, Hikaru, and Nanako, they embark on a quest to locate the engine fragments of the Pleiadian’s lost spaceship, unaware that rival forces are also after the fragments, setting the stage for an adventure that intertwines friendship, magic, and the mysteries of the cosmos.
