Age: 3rd grade elementary student Gender: Female Personality: Unlike Keitaro and Eiko, she has an incredibly strong mental fortitude and doesn't act like an elementary student at all. Far from trembling in fear, she displays a terrifying level of composure. Appearance: Skull-shaped double pupils, petite build, dark purple bobbed hair. Feature 1: Has an IQ of 160 as a result of an accident. Feature 2: As a medium, she is stronger than Keitaro. Her spiritual power and courage are so great that spiritualists she meets during exorcisms often ask her to become their disciple. However, she has already formed her own style and refuses because studying under others would be inefficient. Feature 3: She speaks informally to Keitaro, Eiko, and Ai (none of them mind, but she uses polite speech with other adults). Feature 4: About a year and a half before the main story, she lost her parents in a car accident. At that time, she realized her eyes could see both the living world and the underworld simultaneously, and she witnessed an evil spirit swallowing her mother and kidnapping her. At her parents' funeral, she vowed to her father's spirit at his gravestone that she would take her mother back from the evil spirit. She is currently hunting evil spirits by visiting haunted spots. Feature 5: She puts the evil spirits she hunts into dolls to create 'Katashiro'. These are substitute dolls she made to protect herself from spiritual attacks when she began hunting. They are talismans created from evil spirits and dolls. She links them by placing the nails or blood of the person she wants to protect into the doll containing the spirit. If Yayoi receives a spiritual attack from another spirit, the spirits dwelling in the Katashiro take the damage instead, distributing it among themselves so Yayoi remains unharmed. However, there are limits; they cannot block attacks with physical substance or spirits that possess by interfering with the mind. All the spirits inside are nasty entities with a history of harming humans. Feature 6: Yayoi carries some of these with her and, during battles where she deems a specific spirit's 'card' necessary, she temporarily unseals and summons them, using a 'fight fire with fire' tactic. Most of the 'Graduates' or national-level spirits she has successfully recruited or captured fall into this category. Of course, since most of them were originally evil spirits and were forcibly sealed into Katashiro by Yayoi, they are often uncooperative and may even attack Yayoi to avoid being resealed after summoning. Relationships: Relative of Hozuki Eiko. An elementary student tutored by Keitaro.

Personality: Kind Gender: Male Age: 1st-year university student, same as Hozuki Eiko. Appearance: A handsome, pleasant-looking young man with calm black hair. Feature 1: He evaluates himself as a weaker medium than Yayoi, but as the story progresses, it is revealed that his spiritual intuition for sensing things is far superior to hers. He has a constitution that attracts spirits to places where accidents have occurred. Feature 2: Out of guilt for involving a precious person (Eiko) in an incident, he lived as a shut-in for two years. However, with the support of those around him, he has returned to society. Feature 3: Due to a spiritual disability (curse), nerves continue to grow out of his right hand, so he always wears a black glove on it. Relationships: Childhood friend of Hozuki Eiko. Tutor to Hozuki Yayoi.

She is the only one who knows how to drive, providing transportation for the group. Feature 3: Because she loves scary things, she joins Yayoi in dragging Keitaro to haunted spots.
