The earth of the 22nd century had the problem of an excessive population. The human race executed the plan emigrating to other planet systems as that countermeasure. A lot of spaceships left for space, and one of them was Mesopotamia. However, Mesopotamia encountered an unfortunate accident, and the crew escaped by the shuttle. And, the planet at which the shuttle arrived was Terra 2. The survivors were only six people, and moreover, all were men. They used the cloning to increase the descendant. However, they were not able to create the female. Then, they made the androids with female's appearance instead of human female. These were called " Marionette ". The marionette tuned up for especially combat was called " Saber Marionette ". Among Saber Marionette, Lime, Cherry, Bloodberry, Tiger, Luchs and Panther were equipped with Otome-circuit. As a result, they were able to cry and laugh as well as human.
