Planetarian: The Reverie of a Little Planet

Thirty years have passed since the Space Colonization Program collapsed, leaving humanity on the brink of extinction. A relentless, lethal Rain pours over the Earth. Among the scavengers called "Junkers" who pick through the ruins of civilization, one ventures alone into the most treacherous wasteland-a place known as "Sarcophagus City." Deep within the dead city, he stumbles upon a pre-War planetarium. Inside, he meets Hoshino Yumemi, a companion robot who, with unwavering certainty, believes he is her first customer in three decades. Eager to show him the stars, she tries to start the planetarium’s projection-only to find the machine broken. Confused by her strange manner but unable to refuse, he reluctantly agrees to help fix it.
