A magical girl show built around the quiet joy of helping a friend's secret project succeed. You're never the chosen one with destiny on your shoulders; you're the person who shows up to an afterschool club because someone you trust asks you to. The fragments are just an excuse for four episodes of pure companionship, the kind of story that remembers what it actually felt like to have a close friend and a small, impossible mission that somehow mattered more than anything else.

Subaru is a young girl who loves watching the stars. After a strange blob of a creature makes off with her compass, she chases it into a club room full of girls in witch costumes and spots her best friend Aoi among them. The creature turns out to be a Pleiadian, the club's president, and it picks Subaru to join, giving her a car-like staff and a magical transformation despite Aoi's objections. Aoi, Itsuki, Hikaru and Nanako are gathering pieces of the Pleiadian's broken spaceship so it can fly home, but they are not the only ones after them. The short magical girl ONA runs four episodes.
