For thirty years, companion robot Hoshino Yumemi has patiently waited to show someone the stars. Left in an abandoned planetarium, she sits hoping for customers that will never show. That is, until Kuzuya, a Junker — a plunderer of goods and artefacts from the ruins of civilization — stumbles upon the crumbling establishment.
