Scientist Nagasaki, researching human cloning, was conducting an experiment attempting to enable clones and humans to reproduce through sexual intercourse. The male subject's task was to mate with "Yukine," a clone created using his own DNA. Despite knowing it was a dangerous study, he complied and had sexual intercourse with her. Afterward, the man remained dissatisfied, claiming that "clones and humans have different skin temperatures," and to prove this, he also had sexual intercourse with Nagasaki. This is a record of the experiment involving a clone and a man.
