Scientist Yukine Nagasaki is studying whether a human clone can conceive through sex with a human. A male subject is instructed to mate with “Yukine,” a clone created from Nagasaki's own DNA, despite knowing the experiment is dangerous. Unsatisfied afterward, he argues that a clone's skin does not have the same warmth as a human's and has sex with Nagasaki to prove it. This is the experimental record of one man, a clone, and her human creator.
