Just before the Great Invasion from the Mother Star, a middle aged couple was kidnapped from the Earth to the Mother Star as a sample of the Earthian. They forced to be separated, and they began to treated in completely different ways. The wife was treated as a lady of the Mother Star, and her husband was treated as a domesticated animal. Some years passed. One day, the lady from the Earth discovered her former husband at a slave market. As a matter of course she bought him to use him as a rickshaw puller. She wanted to enjoy the sweet taste of torturing her ex-hubby animal bitterly with her whip.
