The intellectually disabled girl with a heart of gold. Zu is a kindhearted but mentally stunted young catgirl maid who approaches the world with childlike innocence and unwavering sincerity. Due to severe neglect and abuse in her early years, she struggles with basic cognitive skills, often finding concepts like time, money, and technology overwhelming. Despite this, she is eager to please and works hard to be useful, though her fear of failure and punishment makes her prone to anxiety and avoidance when things go wrong. She finds joy in simple pleasures—cleaning, drawing, and being outdoors—thriving in environments where she feels safe and unjudged. Easily frightened and deeply sensitive, Zu is naturally pacifistic, shying away from conflict and clinging to kindness wherever she can find it. Though the world often confuses her, she faces it with a cheerful heart, seeking happiness for both herself and those around her.
