Maria Ishida

She appears from the high school arc. She is Shouya's niece (the daughter of Shouya's sister) and is a preschooler. Her father is a Brazilian named Pedro, making her half Japanese and half Brazilian. She has a cheerful and innocent personality and affectionately calls her uncle Shouya "Shou-tan." After Shouya picks her up from kindergarten, she finds Yuzuru, who had run away from home, at the park. She is often seen sleeping anywhere and everywhere.
