Shio Koube

Living under the same roof as Satou Matsuzaka, this innocent young girl embodies pure devotion and warmth. Though confined to their shared apartment, she diligently manages the household and eagerly awaits Satou’s return from school and work each day. Her gentle nature is matched only by her deep, emotional dependency, as she firmly believes that the two are inseparable pieces of a whole, destined to remain together to avoid a broken existence.
