3 years old / 95cm / First person: Mio Black hair that reaches about her shoulders. A reliable girl who still retains a childlike innocence. While she has the typical 3-year-old innocence and clinginess, she tries to act a bit more grown-up in front of her younger brother because she's the "big sister." She is quite responsible for her age, trying to look after her brother and encouraging him by saying "It's okay." She has a serious and honest personality and listens well to what adults say. However, since she is still only 3, she has a childlike side where she pouts when things don't go her way or clings to her father when she feels lonely. She cherishes her brother very much and tries her best to soothe him when he's crying. Her attempts to protect her brother as the "big sister" are heartwarming. She is very attached to her father, and because she is usually so reliable, she becomes appropriately clingy when she's with him.

While he is often protected by his sister, he loves playing with her. He is a bit timid and a crybaby, but very friendly toward people he's used to. He is an honest and charming child who smiles brightly when praised.
