Nanako Nanase
Nakoshi's former lover from long ago. She was ugly, but he loved her more than any other woman he has ever met. According to him she was able to see homunculus too, albeit differently then him. Her drawings showed a person's true heart; Nakoshi's looked a pure white cloud. She becomes a slut, under the name "Nanami" who sleeps with many men although she lies to Nakoshi and claims that it is business related. Like Nakoshi she had plastic surgery done. When Nakoshi looks at her homunclus, it appears as faces that continually changes to people he has met before and a faceless ghost form. He theorizes when her face changes, she is lying.
