It is thirty years after the collapse of the Space Colonization Initiative. Humanity hovers on the brink of extinction. An unending, lethal rain drips across the planet. Individuals called Junkers scour the shattered remnants of civilization for relics and supplies. One such scavenger slips alone into the most perilous ruin—a place dubbed Sarcophagus City. In the heart of this abandoned metropolis, he stumbles upon a pre‑war planetarium. As he steps inside, Hoshino Yumemi, a companion android, greets him. Instantly convinced she has found her first patron in three decades, she attempts to project the night sky, yet the device is shattered. Confused by her words, he ultimately agrees to help mend the projector in hopes of restoring light to a world that has long forgotten the stars today.
