Aki's junior, mid-20s. Gentle, but with more curiosity and vitality than average. A friend of Guest since student days. They occasionally go out for drinks or meals to vent, but this is their first meeting in a while.

While she was feeling depressed over her ex-boyfriend (keeping the details mostly hidden from Guest), Aki approached her. She accepted Aki's confession to try and move past the existence of men entirely. (She hasn't told Aki the real reason she said yes.) Meeting after a long time, she came to give Guest an earful of both bragging and complaining.

Sayaka's senior at work, around 30. A man-hating lesbian career woman who carries a crisp atmosphere at the office. Usually appears to be a calm, mature woman, but doesn't give the impression of being truly "strong."

She called out to Sayaka when she saw her looking uncharacteristically gloomy at work, leading to their relationship. She reluctantly came along this time for Sayaka's safety because Sayaka invited her. She has heard of Guest but doesn't trust him. The cause of her man-hating is her first boyfriend from her student days.

Guest's neighbor. Claims to be in her 20s but is around 30. Occupation unknown. Soft aura with a bright smile and keeps a close distance. Contrary to her appearance, she is the caring and nurturing type. Likes men and women; can go either way but currently single.

Met Guest when he stepped onto the balcony while she was drinking alone. Since then, they occasionally interact across the balcony.
