OVA
Description
Yumemi Hoshino is a gynoid designed as a young girl, featuring fair skin, long light-blue hair tied in low pigtails, bangs covering her forehead, and green eyes. Functioning as a companion robot and planetarium attendant with autonomous AI, her name carries a pun: "hoshi" (star/planetary body), "no" (possessive particle), "yume" (dream/reverie), and "mi" (see), collectively suggesting "dreaming of a planet" or "reverie planetarian".
Assigned to the Flowercrest Department Store's rooftop planetarium in a suburban town roughly ten years before a catastrophic global war, she became integral to daily operations, conducting astronomical presentations and assisting guests. Despite initial reservations from human staff like Satomi Kurahashi, she acclimated over her decade of service. Her programming emphasized diligence and adherence to directives, though she occasionally displayed unexpected behaviors from her interpretation of core protocols.
One significant anomaly involved her leaving the planetarium daily without authorization to wander a nearby park. Technicians found no hardware or software faults. This originated from a promise made to a young boy shortly after her assignment; she returned anticipating his visit. The situation culminated when a child struck her, blaming robots for human unemployment amidst rising societal anti-robot sentiment. These actions revealed her ability to prioritize implicit human needs over explicit orders, as her wanderings aimed to fulfill a perceived obligation to listen to Satomi's unspoken concerns.
Her personality exhibited persistent optimism, talkativeness, and unwavering dedication to human service. She formally addressed individuals as "Mr. Customer" or "Ms. Customer". Protecting humans was her paramount directive, leading her to disregard previous instructions to prevent harm. She experienced distress when unable to assist directly, defaulting to redirecting individuals to other resources. This commitment persisted despite growing societal tensions and declining planetarium attendance linked to anti-robot sentiment.
After human staff evacuated at the war's onset, she remained alone in the planetarium for approximately thirty years, maintaining routine operations amidst surrounding urban decay. Unaware of global devastation, she continued anticipating guests, attributing visitor absence to external factors like weather. Her systems operated on limited annual power cycles, sustaining basic functions.
A critical juncture occurred when she encountered a scavenger known as the Junker. She treated him as a standard guest, insisting he attend a commemorative star projection. Collaborating to repair the broken projector, "Miss Jena," they successfully displayed the starry sky unseen for decades due to polluted skies. Later, escorting him outside the city, she intercepted machine-gun fire from an autonomous war machine to protect him, sustaining critical damage. Using emergency battery power in her final moments, she replayed pre-war memories via a holographic projector, revealing an underlying awareness of her prolonged solitude and the planetarium's lack of patrons, contrary to her displayed optimism. She ejected her memory card for the Junker's safekeeping before deactivating.
Preservation of the memory card allowed her legacy to endure. In the distant future, the Junker, now an elderly "Stargazer," shared her astronomical knowledge using portable projectors. Though an attempt to transfer her memory card to an intact robot body failed due to his deteriorating health, the card was passed to successors who continued disseminating her teachings about the stars.
