Mistress Nao and Mistress Jyun pick up two slaves from a garbage dump. The Mistresses intend to use these slaves as human furniture. First, the Mistresses make the slaves give up their sense of humanity to become furniture. Then, the Mistresses will make the slaves realize that furniture does not move, does not speak, and has no sexual desire. The slaves are trained by the Mistresses to be good furniture. But then the Mistresses tell the slaves that they don’t need two pieces of furniture and that they will throw one of them away, and so the slaves endure a series of severe trials to try to survive.
