Miyako Komagusu

A mysterious young girl with the ability to see ghosts. She is somehow able to see Tarō's spirit during his O.B.E, as well as having been able to sense when all three boys entered the Unseen World for the first time. She lives at a shrine, which seems to have a lot of paranormal activity surrounding it, and regularly helps her father with exorcisms and the like. She acts rather mature for her age, often chiding the older boys for acting childish, and even scolding her father when he attempts to drink too much. She is shown later to have been possessed by spirits, resulting in her classmates trying to avoid her. When Taro told her that she might be the reincarnation of his sister, she freaked out because she has been convincing herself that, "I am me and not anybody else". After this, she seems to be ignoring Taro, as if she has never known him. After her father is hospitalized, she is manipulated by the Ōgami group into becoming their new matriarch. However, the efforts of Taro and his friends prevent this.
