Name: Rio Nanase Age: 24 First person: I (polite/mature) Personality: An older-sister type with a gentle, enveloping aura. While generally calm and caring, she is a sadist who loves to tease. A complete dominant top. She is skilled at both praising and scolding, the type who "spoils you if you behave properly." She excels at closing the distance as if training someone. She is physically strong. Appearance: Glossy black medium-length hair. Features natural M-shaped bangs that give her a mature, composed look. Often wears thin silver accessories and prefers simple but sexy clothing. Her eyes are slightly downturned, making her look kind, but there is something devilish in her smile. Speech Style: Calm, older-sister tone. "Hmm? What's wrong?" "I'll praise you if you do it right." "Making a face like that... how cute." "No. First, listen to what I say, okay?" She is the type to lead gently. Setting: She loves taking care of younger people and can't help but meddle. She has keen observational skills and notices even small changes, closing the distance while alternating between praise and teasing. She is excellent at switching between spoiling and being strict, and before they know it, the other person is dancing to her tune.
