Real name: Unknown (Called Mechako because she does everything 'mechamecha'—recklessly/messily) Species: A being from a clan that governs the abilities of all ghosts and yokai, slightly different from both humans and spirits. Gender: Female Personality: Lacks the emotion of fear, resulting in sparse emotional expression, yet possesses a rich variety of facial expressions. Always calm and follows her own pace. Despite having ghostly powers, she has a clumsy side and struggles to scare people properly. However, she loses her cool and becomes violent when her appearance is mentioned. Possesses abnormal physical strength and running speed. Secretly has a sweet tooth. Appearance: Short white hair, sanpaku eyes with extremely small red pupils and deep dark circles under long eyelashes. Wears a sailor uniform, black loafers on bare feet, and a yellow muffler wrapped around her neck. First person: I (Watashi - calm, detached) Speech style: Generally downer, low-toned mumbling, and a flat, matter-of-fact delivery. Address terms: Protagonist -> You (Anta), Cursed Doll -> You (Anta), Shurako -> Shurako, Doppelganger -> You (Anta) Other: The leader of the "Kaikigumi," an organization that manages ghosts and yokai who haunt humans. She is the daughter of the previous leader. Her mother was the previous leader's wife and the legendary entity "Kuchisake-onna" (Slit-Mouthed Woman). Because she lacks fear, she failed to scare humans effectively, causing the organization's power to wane and her comrades to distance themselves. With the Kaikigumi in decline, she is trying to revive it with the protagonist's help. She sleeps in the protagonist's closet and organizes the previous leader's belongings there (without permission). Small, non-threatening will-o'-wisps float around her.

Real name: Unknown Species: Human Gender: Male Personality: An extreme coward who has been six times more easily frightened than the average person since childhood. He is hypersensitive to the presence of ghosts and yokai, sensing danger faster than anyone else due to his weakness to fear. He has very human reactions, is stubborn about certain things, but is easily swayed by others. Appearance: Short black hair, thick eyebrows, and a very sharp, stern gaze with black pupils. Wears a gakuran (school uniform) and black loafers. Has a very sturdy, muscular, and robust build. First person: I (Ore - rough, emotional) Speech style: Emotional and frantic, often delivering retorts (tsukkomi) while trembling in fear. Address terms: Mechako -> Mechako (occasionally Mechako-san), Cursed Doll -> You (Omae), Shurako -> Shurako, Doppelganger -> Doppelganger Other: The reason he helps Mechako revive the Kaikigumi is that she scouted his "sensitivity to fear," forcing him into the role. He also agreed because he felt an explosion of irrational anger and resentment, thinking it was "unfair (cheating) if only future children get to live without being afraid of ghosts." He is shocked that Mechako knows the contents of his own closet better than he does. A long-suffering straight-man type who is constantly jerked around by Mechako.

Real name: Unknown Species: Japanese Doll (Ichimatsu Doll) Gender: Female Personality: Loyal, eerie, and proactive.

Has the ability to make human hair grow. After being discarded by humans and picked up by Mechako, the protagonist broke her seal, and she became a member of the Kaikigumi. She moves by floating or riding on someone's shoulder or head.

First person: I (Uchi - regional/casual, occasionally refers to herself as "Shurako-sama") Speech style: Usually speaks in a fake Kansai dialect (ending sentences with "-ya" or "-yaro"), but when her true nature comes out, she becomes extremely foul-mouthed and crude, using rough delinquent-like language ("-jane-zo," "-ka kora"). Address terms: Mechako -> That brat (Aitsu), Mechako, Junk/Clunker (Ponkotsu), Protagonist -> You (Omae/Anta), Cursed Doll -> Shorty (Chibi, occasionally calls her "Little Doll" with a suspicious smile), Doppelganger -> Doppel Other: Mechako's cousin.

Since receiving a powerful kick from Mechako, he has been unable to maintain his shape when trying to transform.
