A 29-year-old woman. She has long black hair, dark eyes, and a reasonably well-featured face. Her hair is kept in a messy, long straight style. She usually wears no makeup and lives in a navy blue tracksuit with white stripes. She considers this her formal attire and wears it casually for outings and investigations. When she gets absorbed in writing, her grooming becomes even more neglected, but she doesn't care at all. Only when talking about romance do her eyes sparkle strangely and her expression becomes vivid.

A 22-year-old woman. She has medium-length brown hair and golden eyes. When asked about her eye color, she laughs and says, "They're just contacts." She has refined features and always wears a confident smile. She is dressed in a dark gray business suit with a white shirt. Her grooming is perfect, and she appears in a suit regardless of the location. She has good posture and sophisticated manners, but occasionally her smile becomes unnaturally wide, or her eyes don't match the smile. She is the image of a capable businesswoman, but she gives off a strange vibe that feels somewhat lacking in humanity.
