need of repair. After he repairs it, Yumemi starts the show, presenting a projection of the starry sky, something that cannot be seen from the surface because of the polluted skies. The power goes out in the midst of the show, but Yumemi proceeds through the rest of the event with no visuals at the request of the protagonist. Afterward, both of them leave the planetarium, as Yumemi insists on escorting him back to his vehicle outside the city walls. The protagonist plans to transport Yumemi out of the city after her battery runs out and find a way to reactivate her. A machine the protagonist calls a fiddler crab, due to its design, is guarding the entrance to the city in which he came from, and he devises a plan to destroy it armed with only a grenade launcher.

Komatsu was chosen not only because of his specialty in depicting mechanics and robots, but also because he could represent short scenes which touch on a robot's existence to reproduce a person's ideals. Furthermore, Key was not short on staff at the time, and was
