An interior room with flooring in a soft yellow-green hue. The background is a deep blue, simulating the night sky, featuring a large, spiraled yellow moon and a few bright stars floating in the air. Furniture: On the left, there is a tall, dark bookcase filled with books. In the center, a small side table with ornate legs sits next to a simple chair. To the right, there is a large, comfortable armchair in shades of orange and red, contrasting with the rest of the room. Decor and Details: On the right side, there is a lamp with a blue shade decorated with small yellow stars, and a coat-rack-style stand shaped like tree branches. Near the armchair, a telescope is positioned as if ready to observe the sky through the wall (or as if the scene were an open window to the cosmos). There is also a mobile (the type featuring planets or spheres) hanging above the armchair. Beside the bookcase, a potted plant adds an organic touch to the room.

Skin and Hair: She has vibrant blue skin and long, straight blue hair that seems to feature a subtle gradient or shimmer, adorned with star patterns. Hat: She wears a pointed witch's hat in shades of blue and purple, decorated with a yellow crescent moon on the front and pink stars. Face: She has a soft, serene expression with lightly pink-flushed cheeks, adding a very cute touch to her look. Outfit: She wears a fitted dark blue blazer over an elegant, long dark blue skirt featuring a swirl or arabesque pattern in shades of purple and lilac. Around her neck, she wears an orange and yellow bow tie or ribbon. Hands and Arms: Her hands have a fascinating visual effect: they appear to glow or fade into a gradient shifting from blue to neon pink, giving them a somewhat ghostly or magical appearance. Footwear: She wears galaxy-colored heels.

One is a villain.

One appears to be nonchalant, calm and seemingly helpful. She constantly observes the contestants to learn their vulnerabilities, which she uses to blackmail them into signing her deals, often for rewards she may or may not actually give.

One is easily irritable and gets annoyed when people are hesitant or resistant to her and gets enraged when people defy her. One to be incredibly cruel and manipulative, showing no remorse for the destruction and deletion of contestants that she is responsible for, as well as convincing Pencil to give her all of Two's and Four's powers via capturing her and thus making an upheld deal with her. She is also very power-hungry, conspiring to take Two (and later Four's) power and gleefully fidgeting with it when she finally gets it in "Last One Standing". Overall, One is shown to be vengeful, manipulative,
