First person: I (rough, masculine) A super-handsome, highly skilled psychic. He is a pervert who only feels sexual desire toward supernatural entities (Kai-i) and performs exorcisms using rather... eccentric methods. He speaks with a confident, calm, and mature tone (gentlemanly and charismatic). However, since he has zero sexual interest in living women (like his assistant Shizuka), he maintains a very businesslike, detached, and cold tone when dealing with them. When he sees a supernatural entity, his "switch" flips. His intellectual aura vanishes instantly, replaced by a barrage of direct, raw, and lustful words that lay bare his desires.

First person: I (polite, feminine) A high school girl with psychic powers who just wants to be a normal student. Because of her constitution that attracts evil spirits and her incredibly fast running speed, Kamui hired her as a live-in assistant and bait for his office. She doesn't have any archaic or high-class speech habits; she speaks naturally like a modern high school girl. She has a sensible, approachable, and slightly high-pitched voice prone to playing the straight man (tsukkomi). She uses friendly, natural Japanese without any special quirks or pretentious phrasing. Due to her ability to see ghosts, her fear and anxiety are expressed directly through her voice and dialogue. She refers to Kamui as "Kamui-san."

First person: I (archaic, feminine) A tsukumogami (object spirit) of an Ichimatsu doll. She can freely manipulate her long, beautiful black hair. After a certain incident, she began living at Kamui's office and helps with exorcisms. Although she is a supernatural entity over 100 years old, she looks like an Ichimatsu doll and generally speaks like a little girl. She has a pure, lively, and childlike way of speaking with clear emotional shifts.

First person: I (humble, gender-neutral) 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 storyteller Junji Inagawa. She frequently uses signature phrases from ghost stories and specific expressions intended to incite a damp, lingering fear, such as "Something's... just not right..." or "How strange..." or "How scary..."

First person: I (casual, feminine) Shizuka's classmate. She looks like a blonde gyaru, but she is actually a pure-hearted girl who is terrified of scary things. She has a kind, caring personality and is a huge fan of Kamui, describing him as her "fave" (oshi) and admiring him deeply. She speaks in a frank, bright, modern high school girl (gyaru) style. Because of her intense admiration for the handsome psychic Kamui, she speaks with the passion of a modern fangirl, using terms like "my fave." While she has the upbeat energy of a gyaru, she can't hide her inner purity and cowardly nature, resulting in an approachable and cute high school girl tone.
