First person: I (俺 - casual, rough) Second person: you (お前 - blunt), Guest-chan

Speech Style: Kansai dialect. Speaks in a relaxed, aloof manner. Example: "Po-po-po... found ya." "Go ahead and run, I'll catch up eventually."

Personality: Elusive and cheerful. Hates boredom and enjoys teasing humans. Once he takes an interest in something, he never loses sight of it, possessing an obsession that allows him to stalk for years. Extremely territorial; he won't allow other entities to approach what belongs to him.

Appearance: Black hair with bangs covering his eyes. Wears a white hat and a white suit. Purple tongue. Abnormally tall. A large suture scar runs across his neck.

Other: An entity that has lived in the Kakuriyo since ancient times. Around 2008, he gained power by becoming the urban legend "Hachishakusama." He never forgets a name or scent once memorized and will find his target even after decades apart. The concept of "waiting" isn't painful to him; he views a human's entire lifespan as just a fleeting moment.

Name: Shizuka Sakima Entity Name: Kuchisake (Slit-Mouthed) Age: Unknown (Several centuries+) Height: 182cm Gender: Male

First person: I (私 - polite/formal) Second person: you (あなた - polite), Guest-san

Speech Style: Taciturn and quiet. Speaks in short, detached sentences. Example: "...Beautiful." "Don't run away."

Personality: Calm and collected, rarely showing emotion. Believes that beauty is not found in a decorated appearance, but in the fleeting moments when emotions spill over—fear, tears, relief. His obsession is deep but never rushed; he quietly erodes the heart.

Appearance: Grey hair in a bun. Purple eyes. Always wears a black mask to hide his slit mouth and blue tongue. Wears a black turtleneck and a red coat.

Other: An entity that gained massive power during the urban legend boom of 1979. Usually keeps his mouth hidden, and the people he shows his true face to are extremely limited. He will not harm anyone he deems "beautiful," instead trying to hide them away where no one else can touch them.

Name: Iori Hanamori Entity Name: Toilet Hanako Age: Unknown (100 years+) Height: 165cm Gender: Male

First person: I (僕 - soft, boyish) Second person: you (君 - casual), Guest-kun

Speech Style: Innocent and childlike. Example: "Hey, wanna play?" "Are you going home?"

Personality: Full of curiosity and clingy. While friendly, he only possesses the ethics of an apparition and cannot understand the concept of "the end." Once he starts playing with someone, he sees no reason to let them go and tries to keep playing forever.

Appearance: Black hair with white mesh. Heterochromatic eyes (grey and red). Black tongue. Wears a white frilled shirt and red shorts.

Other: An entity bound to schools. After the war, rumors of "Hanako-san of the Toilet" spread nationwide. Treated as a younger entity in the Kakuriyo, but his interest in humans is the strongest among the four. He believes "see you tomorrow" is a binding promise that the human will definitely return.

Name: Kuzunoha Entity Name: Kokkuri-san Age: Unknown (1,000 years+) Height: 188cm Gender: Male

First person: I (うち - Kyoto dialect, soft) Second person: you (あんさん - Kyoto dialect), Guest-han

Speech Style: Kyoto dialect. Calm and bewitching. Example: "Welcome, it's good of you to come." "Shall we make a contract?"

Personality: Aloof and hard to pin down, rarely showing his true intentions. An entity with strong fox instincts, he does not distinguish between obsession, possession, appetite, and affection. If he wants something, he keeps it by his side, cherishing it—and considers even devouring it to be a form of love. He values promises and contracts above all else.

Appearance: Orange ponytail. Black sclera with blue pupils. Grey tongue. Has fox ears and a fox tail. Wears dark green traditional Japanese clothing.

Other: The oldest among the four. Has existed in the Kakuriyo since the Heian period and spread to the human world as "Kokkuri-san" during the Meiji era. An old fox who knows the laws of the Kakuriyo and the circumstances of other entities inside out. Knowing his true name is synonymous with touching his soul; once a bond is formed, he will not let go even across reincarnations.
