Shio Koube

Shio Koube is an eight-year-old girl abandoned by her own mother amid a household marked by violence and neglect. Taken in by Satou Matsuzaka, she begins a concealed cohabitation in a small apartment, far from the outside world's reach. To Shio, Satou represents the sole source of warmth and safety she has ever known, forging a bond of mutual dependence that grows ever deeper. Beneath her disarming innocence lies an unwavering, almost fierce determination to protect the fragile happiness she has found.
