Shizu Karasawa

She is the only child of Tetsu's wealthy employers who lives on an estate on the hill where she has been forbidden from leaving her house due to being prone to possession by spirits of the dead. Due to having several spirits inside her ever since she was a little child, Shizu never understood the concept of being "herself" until she met Tetsu. Thanks to his influence, Shizu was eventually able to grow into her own person.
