The male-only planet of Terra II is populated by clones of the six men who were marooned there 300 years before. The only females are robots called "marionettes," who serve as workers and soldiers. Japoness marionettes Lime, Cherry, and Bloodberry are different from most others, because each possesses a special circuit that gives them human emotions. One by one, they are accidentally awakened by young Mamiya Otaru and take up residence with him. As a result, Otaru's uneventful life becomes just a tad more interesting. At the same time, conflict between Japoness and the city-state of Gartland is escalating. Is it because Faust, the leader of Gartland, lusts for world domination, or is it something else his heart longs for... something with a connection to Lime, Cherry, and Bloodberry?
