Nero

Nero is the seven-year-old daughter of Shiu, a seasoned interrogator, and the younger of a pair of twin sisters alongside Reu. With her dark black hair and characteristically unhurried, self-paced nature, she moves through life entirely on her own terms. She is a familiar face at her father's workplace, an organization known as 'Water of Life,' where she shares a warm and easygoing rapport with staff members such as Sairo. Deeply devoted to her family, she holds a special fondness for the color white—the signature color of both her father and her sister—and serves as a genuinely pure and soothing presence throughout the story.
