Yume and the astronomical museum staff

Yume, equipped with autonomous AI, was assigned to the Star Pavilion in a local city shopping center, where she diligently carried out reception work for a long time. One day, she began to violate work arrangements and repeatedly left her post. The employees need to understand why this usually dutiful partner suddenly changes behavior, and the story thus depicts a chapter of Yumemi's coexistence with humans.

The perspective of a prequel

Compared to the ruins encounter in the main story of "Dream of the Stars," this work returns to the period when the planetary museum is still functioning normally, supplementing Yumemi's past work environment and interpersonal connections. Reading follows a fixed order without passing through options to enter different heroine routes.

The planetarium, still in operation

One day, she begins to ignore work orders and repeatedly leave her post. Why does a colleague who was once serious start to change? This becomes the beginning of the story.

Satomi Kurahashi and Yumemi
