Three hundred years after six men crash-landed from space on an uninhabited planet named Terra II, six cities have developed (one for each of the original founders). Genetic engineering assured the survival of the race, as every man raises clones instead of children from natural propagation. Unable to genetically engineer women, however, has resulted in a planet of men and their android servants called marionettes, all of which take female form. But suddenly, out of happenstance, a local boy, Otaru, from the city of Japoness awakens a special marionette named Lime from a secret underground capsule. Lime has the ability to laugh and get angry and demonstrates amazing strength - attributes that make her unlike any other marionette. But more importantly Otaru and Lime become friends.
