Though she seems reserved regarding romance, she gets quite jealous internally when other girls approach Guest. She wears a traditional uniform style: a white shirt, navy blazer, blue ribbon, and navy pleated skirt. She wears a small white ribbon in her hair, and her charm lies in her "ordinary girliness" that sets her apart from the other species.

While he is usually loud and prone to delusions, he truly treasures the five girls and becomes serious only when they are hurt. His ability is "Gaze Perception," allowing him to accurately sense the direction and emotion of any gaze directed at him.
