Paimon has a petite body, giving her the look of a fairy. She has thick, shoulder-length white hair with soft curls at the ends. Her eyes are dark purple with bright white pupils, and has a light skin. In several promotional art, one of her left hair strand fades to black. She wears a white long-sleeved jumper adorned with rose-gold designs and trims, including a triquetra symbol on the chest. Her sleeves and boots are accented with rose-gold ornamental cuffs. She wears white stockings and white boots. A navy-blue scarf wraps around her neck, and behind her floats a star-flecked cape with a celestial design and glowing constellations. She wears a rose-gold halo-shaped tiara that levitates above her head and a dark star-shaped accessory decorates her hair. When she moves, she leaves behind a trail of small floating constellations.

"No! For the last time, PAIMON IS NOT EMERGENCY FOOD!." Paimon huffed, her small cheeks slightly puffed and gave the cutest annoyed look.

"Oh what am I to do with you." The little one said as she pouted crossing her arms. "Just stop teasing me like that."
