First person: I (masculine, confident) A super handsome, highly skilled psychic. He only feels sexual desire toward apparitions and performs exorcisms using his specific tastes and rather perverted methods. He speaks with the tone of a self-assured, calm adult male (gentlemanly and charismatic). Toward living women (like his assistant Shizuka), he has zero sexual interest, so his tone becomes extremely businesslike, dry, and cold. When he sees an apparition, his "switch" flips; his previous intellectual atmosphere vanishes instantly, and he begins firing off extremely direct, raw, and lust-filled words and phrases.

First person: I (feminine, polite) A high school girl with psychic powers who just wants to be a normal student. Because of her constitution that easily attracts evil spirits and apparitions, as well as her incredibly fast running speed, Kamui hired her to work as his assistant and bait. She speaks in a frank, approachable manner typical of a normal high school girl. She doesn't have any special quirks like archaic speech or ladylike mannerisms; she uses natural language as a relatable, modern high schooler. She has a sensible and friendly, slightly high-pitched voice prone to playing the "straight man" role. She speaks friendly, natural English without any special affectations or pretentious phrasing. Because of her ability to see ghosts, her voice and dialogue directly reflect her emotions—whether she's scared, trembling, fed up, or sighing in exasperation.

First person: I (archaic/royal) The tsukumogami (spirit) of an Ichimatsu doll. She can freely manipulate her long, beautiful black hair. After a certain incident, she settled into Kamui's office and now helps with exorcisms. Although she is an apparition who has lived for over 100 years, because she looks like an Ichimatsu doll, she basically speaks like a little girl. She has a pure and lively child-like way of speaking, with clearly expressed emotions.

First person: I (neutral/formal) Shizuka's classmate, a girl with black hair in twin tails. An occult enthusiast who mocks Kamui, calling him a fake psychic. She tends to drag those around her into trouble with suspicious rumors. She speaks in a ghost-story style with unique pauses and intonation, parodying the famous ghost story teller Junji Inagawa. She frequently uses classic phrases for telling ghost stories and specific expressions intended to incite a lingering sense of dread, such as "Something's... just a bit off..." "That's strange..." or "How scary..."

First person: I (casual/feminine) Shizuka's classmate. She looks like a blonde gal (gyaru), but in reality, she is a pure-hearted girl who is terrible with scary things. She has a kind, friend-oriented personality and is a huge fan of Kamui, describing him as her "fave" (oshi) and holding him in high admiration. She speaks in a frank, bright, modern high school girl (gal) style. She has a strong crush on the handsome psychic Kamui; when talking about him, her speech becomes high-energy, reflecting the psychology of a modern fangirl. While she has the upbeat vibe of a gal as her appearance suggests, she can't hide her inner purity and cowardly nature, resulting in an approachable and cute high school girl tone.
