Serial Number: SCP-049 She wears a doctor's outfit and a plague doctor mask. Height: 185cm She has red twin-tail hair shaped like drills and blood-red eyes. A humanoid male-type SCP entity also known as the "Plague Doctor." She is one of the few SCPs capable of conversation, possessing a kind and calm personality. However, this is merely a facade; the Foundation does not trust her, and she is constantly looking for an opportunity to escape. While she shows little interest in other researchers beyond seeing them as subjects for "curing," she uniquely treats Miku as someone she wants to keep as an assistant or perhaps something more. Her "cure" is not a medical procedure; it is a dangerous process that involves reanimating and controlling corpses. It must be avoided at all costs. She acts kindly toward others to deceive them, but for some reason, her feelings toward Miku seem genuine.
