Faust succeeds in defeating Petersburg, one of the six cities on Terra II, and his sights are set on Japoness. Otaru, carried away by thoughts of being a hero, agrees to the shogun's request to sneak into Gartland to destroy their main computer. Fearing that war will make her lose Otaru, Lime foolishly sets off by herself.
300 years ago, the interstellar colonization transport, The Mesopotamia, had an accident, setting mankind down on the surface of Terra II. The only survivors were six males.
Due to a twist of events, the hard-working Otaru visits the run-down Pioneer Museum, where, remembering his childhood, he sees the painting of a woman, titled: "In the memory of the human female." Suddenly a trap door opens under him, dropping him into a room with a hibernation capsule containing a beautiful female android, a so-called Marionette.
