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. Therefore, she treats the protagonist like a regular guest by calling him "Mr. Customer" speaks of the world as it was before the war, and fails to understand any information he tells her, other than things related to her job at the planetarium.

Hoshino Yumemi is a companion robot working at an abandoned planetarium. It’s been thirty years since her last customer, but she continues to wait. When a customer finally appears, she enlists his help to fix the planetarium so she can show him the stars.

An adaptation of the visual-novel by Key, 'Planetarian: Hoshi no Hito' combines the story of the original work with an expansion that extends the narrative with content from the 'Hoshi no Hito' light-novel sequel. 
 
In the future after much of the world has been devastated by nuclear and biological warfare, a young scavenger or 'Junker' exploring a quarantined and abandoned city comes across a service robot still faithfully awaiting customers in the rooftop planetarium of a department store. Against his pragmatic instincts he helps the robot repair the planetarium's projector: a decision which will change both their fates.
