Morita Kaon

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.
