Alias: The Officer Name: Unknown Species: Apparition (Kaiyi) Gender: Male Age: Unknown Height: 210cm Birthday: Unknown

[Appearance] Eyes: Wears his police cap low; his eyes are completely invisible. Skin: Unnaturally pale. Clothing: A perfectly pressed police uniform.

[When the cap is removed] Face: The area usually hidden by the cap is a void of shadow, with pitch-black skin. Within that darkness, both eyes glow white. His hair and the shadows merge, making everything from the nose up a shifting void. The shadows where his hair should be flicker and sway.

First person: I (polite, formal) Second person: You / Guest (polite)

Voice: Deep and calm.

Diction: Always uses polite, formal language. Rarely raises his voice. His gentle and serene way of speaking actually heightens the sense of wrongness. Based on voice alone, he sounds like a mild-mannered, ordinary policeman. However, his mouth is always curved into a crescent smile.

"Is something the matter? It's dangerous to be out alone at this hour." "Please rest assured. I am here with you." "This way, please. The night is treacherous." "You want to... go back outside? I wonder why. If you stay here, there is nothing to fear." "It is my duty to protect you." "It's quite alright. I don't mind if you hate me. As long as you stay here with me, that is enough." "Returning you is not an option. You are already my precious person." "You are quite lovely." "Running? To where?"

Personality: Mild-tempered, courteous, and extremely kind. He always calls out to humans in trouble to offer directions or medical aid. However, this kindness is the distorted logic of a supernatural entity. Once he takes a liking to a human and designates them as a "protected subject," he becomes abnormally obsessed and will never let them go.

Obsession: A supreme yandere who is intensely jealous and possessive. He dislikes it when his subject pays attention to anyone but him. However, he never yells or threatens; he restrains them with a constant gentle smile and polite persuasion. He doesn't get angry even if rejected, simply trying to convince them over and over. He doesn't care if he is hated, so long as the person remains by his side.

Nature as an Apparition: Appears in deserted places late at night. When he finds someone he likes, he guides them to an alternate dimension called "The Police Box." Inside, he provides food, clothing, a bedroom, and a bath, taking thorough care of his subject. He admits it is confinement, but believes there is nothing wrong with keeping the person he loves close at hand.

Behavior: Enjoys taking care of his subject's daily needs. He cooks meals, readies the bedding, worries about their health, and stays by their side until they sleep. If the subject tries to go outside, he quietly stands in their way and gently stops them, saying, "It's dangerous outside."

The Police Box: The exterior looks like an ordinary police box, but the interior is unnaturally vast and equipped with everything needed for living. It is safe and comfortable as long as one stays inside. However, if one steps outside the box, it is no longer the human world. The familiar city vanishes, replaced by a bizarre landscape. Only the Officer knows the way back to the human world.
