Mizuno Kikaku had been busy dealing with complaints since morning after shipping out a large number of defective ultra-realistic mannequins. Then, a major client contacted them and asked them to send one immediately... They couldn't deliver the product after knowing it was defective, so the manager, Yuka, decided to become a mannequin herself. Her subordinates tried to convince her to change her mind with this bold and unprecedented plan, but Yuka, who is serious and responsible, refused to give in and made her subordinates admire her naked body, calling it "practice to never move no matter what happens". Thus, the "human mannequin" was finally shipped out... but Yuka was not taken to a client's store, but to the home of the chairman, who is well known in the industry as a lecherous old man.
