Yumemi Hoshino

Yumemi Hoshino is a goodhearted, extremely talkative gynoid attendant at an abandoned planetarium, designed to resemble a young girl. Slightly damaged and unaware of the changes of the past 30 years, she still treats the protagonist as an ordinary visitor and calls him “Mr. Customer.” Her disconnected facilities and databases leave her unable to grasp most information outside her planetarium duties.
