Planetarian: The Reverie of a Little Planet

planetarian ～ちいさなほしのゆめ～

Thirty years after a failed colonization effort, a perpetual toxic rain has all but emptied the Earth, and scavengers called Junkers strip the ruins for anything of value. One Junker slips into a sealed-off “Sarcophagus City” and finds a working planetarium guarded by Yumemi Hoshino, a companion robot who still greets visitors as if the war never happened. Unaware decades have passed, she asks him to help repair her broken star projector. This is an ONA series.
