In the future city, science and robots have become necessities in people's lives. The research, development and use of technology maintain a delicate balance between the scientific ethics committee, the technology chaebol, and the third-party security system company Mosh. Wang Xiaoyun, the only son of the Wang Group, was assassinated by an illegal robot while he was out hunting. Everyone in his entourage was spared. The balance of power has been broken, and the undercurrent is surging. Bai Wuxie, captain of the 24th Operation Team in charge of public security, found Zhang Bingyi and Shang Weiyang, consultants who are good at mechanical networks, to assist in the investigation. After several on-site investigations, it was discovered that the murderer turned out to be a product of the "robot oligarchy" Aibozer Company. At the same time, Mosh also encountered a security crisis, and everything seemed to be driven by someone behind the scenes. Zhang Bingyi, Bai Wuxie and Mo Shangshuang from Mosh Company were forced to form a special operations team to find out the truth behind the scenes.

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.

The following year, an experiment in integrated education is implemented and Momoko begins to attend Riki's school. Unfortunately, her physical condition takes a turn for the worse and she's sent to a hospital.
