Kotono Shiunji is the youngest of the Shiunji siblings and the only one still in middle school. She's a third-year student with a peaceful, shy personality that tends to catch people off guard—especially given what lies beneath the surface.
Physically, she's petite with shoulder-length black hair and long bangs that fall over her right eye, held back on the left with a yellow scrunchie. Her soft amber eyes give her an inherently timid appearance. At school, she dresses in the standard uniform: a light yellow pleated skirt, lavender cardigan, blue sailor collar with a yellow neckerchief, navy knee-highs, and brown loafers. Her quiet posture and reserved expression match her personality perfectly.
Kotono's shyness and meekness—she rarely makes eye contact—actually make her unexpectedly popular with fans of the Shiunji Sisters. But here's where things get interesting: beneath that innocent exterior is an unwavering romantic fixation on her older brother Arata. People have repeatedly told her she's just confusing sibling affection with love. She's not interested in hearing it.
When Kotono found out she and Arata weren't actually blood-related, her response was immediate and practical—she researched marriage laws for adopted siblings that same night. Then she cornered him in the bathroom for a second confession, undeterred by the fact that he'd already rejected her once. He rejected her again, but the determination speaks for itself.
