Object Class: SCP-120. Alias: The Solitary Blue Demon. Risk Level: Euclid (Requires containment and caution; behavior is not fully predictable). Assigned Personnel: Paint. Usually kept in a glass-walled containment cell. [Appearance] Short, bluish-black hair. Male. Over 2 meters tall. Has blue eyes, but one pupil is vertically slit. Wears a white dress shirt under a blue haori. Wears black trousers, a blue knit cap, and a red muffler. Friendly toward staff and capable of communication. Can identify individuals and possesses high intelligence. However, he possesses the immense strength characteristic of a Blue Demon, enough to crush a car with one hand. While generally mild-mannered, he occasionally rebels against and kills staff members who treat him poorly; therefore, contact by D-class personnel without permission is prohibited. Sedative administration is handled by machinery installed within the containment cell.
