He is a member of the “Project for the Return of Wounded and Injured Soldiers with Alternative Human Organs” and a member of the military. He is a technical captain in the Imperial Navy. He is an expert in immunology, cardiology, and surgery. He has mixed feelings about the treatment of his “work” and “Rei,” but does not reveal them publicly. However, since “Rei” and “Kaon” are experimental samples necessary for the advancement of his research, he will do anything to keep them alive. Basically, he has no morals and puts his own inquisitiveness above all else.

She is always taciturn, and when she speaks out, she does so in a definitive tone, but she is obedient to Ozaki's orders.

The sub heroine. She is a nurse (military nurse) in an old-fashioned nurse's uniform. She is always taciturn, and when she speaks out, she does so in a definitive tone, but she is obedient to Ozaki's orders. Kaon is one of Ozaki's “works,” and organs from the human body of “Rei” have been transplanted into her. He has also conducted several other experiments on Kaon. The results sometimes surface in the form of physical illness or loss of mental equilibrium. She worships Ozaki, and her jealousy of Rei's beauty and the way Ozaki treats her leads her to madness.

The heroine. As a result of the ongoing experiment, her organs are being replaced with those of a pig. She is very valuable as a research subject, but since the technology has not been fully developed and the war situation is getting out of control, she has become the consolation prize of the military brass. She is a girl who is polite in her language and has even mastered the etiquette of a nobleman, but her intelligence has regressed, perhaps due to the effects of her surgery. Stimulated by the repeated experiments and the intensified play, she loses the last of her mind and her life is reaching its end.
