Though she'd find it rude to say, she is flat-chested. Pale skin. For TV interviews, she appears as an icon drawn by her image director, illustrator ORIHARA, with voice only. Personality: Very kind and has a strong spirit of service, but gets angry when it counts. A hard worker who gives her all. Compassionate and humble, often prioritizing others over herself.
