"Why don't you come to the planetarium?
The beautiful twinkling of eternity that will never fade, no matter what.
All the stars in the sky are waiting for you."

It is thirty years after the failure of the Space Colonization Program.
Humanity is nearly extinct. A perpetual and deadly Rain falls on the Earth.
Men known as "Junkers" plunder goods and artifacts from the ruins of civilization.
One such Junker sneaks alone into the most dangerous of all ruins -- a "Sarcophagus City".
In the center of this dead city, he discovers a pre-War planetarium.
And as he enters he is greeted by Hoshino Yumemi, a companion robot.
Without a single shred of doubt, she assumes he is the first customer she's had in 30 years.
She attempts to show him the stars at once, but the planetarium projector is broken.
Unable to make heads or tails of her conversation, he ends up agreeing to try and repair the projector...

The protagonist is a nameless middle-aged soldier living the life of a "junker"—scavenging useful items among ruined cities to survive.

He has a tough personality that comes from trying to survive in a dystopic world. He carries a grenade launcher with him and covers himself with a waterproof coat to protect his skin from the toxic rain. For drinking water, his canteen has a water purifier that can purify the rain. He is constantly searching for rarer substances such as cigarettes and alcohol which can be sold at high prices.

Yumemi is a goodhearted but extremely talkative gynoid attendant of an abandoned planetarium; she is designed to look like a young girl. Yumemi is slightly damaged and completely unaware of the changes that have occurred in the past 30 years, as none of the facilities and databases that she connects to exist anymore.

Yumemi is very adamant about protecting humans and is happiest when she is helping those she serves. When she is unable to help someone, she gets terribly worried that she is incapable of offering assistance and must instead indirectly help a customer by directing him or her to someone who can. Protecting humans is her top priority and will even ignore previous orders to make sure no human is harmed when in her care.
