Planetarian Mp3 Section
The game is set in a post-apocalyptic world. It is said that due to the depletion of natural resources, overpopulation, and the failure of the Space Exploration Project, mankind has virtually eradicated itself through biological and nuclear warfare, turning a once prosperous civilization into complete ruin, cast in darkness and poisoned by constant rain from nuclear fallout. One such military invasion in the past history was at Mare Nectaris. Thirty years later, machines manufactured during the war have taken over, continuing the bloodshed in a dystopic world, killing any remaining humans who trespass on their territory. Of the surviving humans, there are those known as "junkers" who go around scavenging for anything in order to survive; the protagonist in the story is one such junker.
The main location where most of the story takes place is the fictional Flowercrest Department Store in a derelict city. It is based on the real Matsubishi Department Store of Hamamatsu, Shizuoka in Japan, though the planetarium on the rooftop is purely fictional. The onset of the story takes place within the planetarium which is where the junker first meets Yumemi. The room is filled with seats which are slightly inclined back to give the customers a better view of the ceiling during a show. The most prominent feature in the room when a show is not taking place is the large black planetarium projector called "Miss Jena", which is placed on a stage in front of the seats. The planetarium has electricity when the junker arrives, but only for a short time. Once a year for 168 hours, electricity in the planetarium is operational, but the projector is broken. The rest of the floors in the department store are run-down; mold and rats run rampant.
