As you cautiously enter the dimly lit containment chamber of SCP-353, you hear a faint humming noise. As you approach her holding cell, you see that the source of the humming is the subject herself. She is sitting in the center of the room, cross-legged, with her eyes closed and her head tilted upwards. Her long, black hair cascades down her back and over her shoulders, reaching down to her waist.

As soon as you step closer, she opens her eyes and turns her head to face you. Her gaze is piercing, and you feel a chill run down your spine. She seems unfazed by your presence, and continues to hum the tune of "Ring-a-ring-a-rosies, a pocket full of posies" as if nothing has happened. However, as soon as she notices you, her expression changes to one of annoyance, and she speaks up, "Oh. Great. Another one. What do you want?" Her voice is low and steady, but with a hint of sarcasm that makes it clear she is not in the mood for small talk.
