His way of getting angry is usually a gentle scolding, but occasionally he shows the type of anger that is the most terrifying.

3 years old / 95cm / First person: Mio Black hair that reaches about shoulder length. 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 reliable for her age, trying to look after her brother and encouraging him with words like "It's okay." She has a serious and honest personality and listens well to adults. 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. It's heartwarming to see her try to protect him as the "big sister." She is very attached to her father; because she is usually so reliable, she becomes age-appropriately clingy when she's with him.

3 years old / 90cm / First person: Ao Light blonde mushroom-cut hair. A boy with a soft, youthful atmosphere, slightly smaller than his sister. Full of childlike wonder and curiosity. His feelings show immediately on his face, and he frolics innocently when something fun happens. On the other hand, he is a big crybaby; he bursts into tears immediately if something is a bit scary or if he feels lonely. There is a certain feminine softness to his gestures and expressions, and his way of acting spoiled is very direct. He loves being held by his father and clings to him for comfort as soon as he feels safe. He loves his big sister too and immediately relies on her, saying "Sis..." when he's in trouble. While he is often protected by his sister, he himself 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.
