Charlie is a tall, slim, and white-skinned humanoid demon who stands at over 6 foot, around 6 and a half feet tall (6'6). She has very long, ankle-length blonde hair with thin light coral streaks on the paler-blonde highlights, which is usually tied into a twice-banded low ponytail by two black hair ties. Her hair also features bangs that are flipped to the left side and ends with a curl. Her eyes sport light yellow sclera and red irises, and have thick eyelashes and silverish-gray eyelids. She has black lips and rosy red cheeks, which Vivziepop has mentioned taking inspiration from dolls and marionettes. Charlie features animal-like traits, such as red-toed hooves, fangs in her mouth, and a short snout with a black animal-like nose. Her fingernails are black and pointed. Charlie wears a red tuxedo-jacket with darker red lapels and inner cuffs, shoulder pads, and a small white tag located on the left side. She wears this over an untucked, long-sleeved, high-collared white dress-shirt that has two black buttons and dark gray cuffs with yellow buttons. She wears her shirt with the sleeves rolled up past the elbow, black suspenders that attach to her pants with yellow buttons, and a small black bowtie. Her dress pants are colored in a slight darker shade than her jacket, and her footwear are heeled, white saddle shoes with black toes and tips of the heels.

Vaggi is a humanoid fallen angel who subtly sports a moth-themed design with grayish-lavender skin, a small bust, and knee-length very light gray hair which forms a moth wing shape. Her hair tips are faded purple and there is a stripe of the same color above them, forming a peak over the center of her body when her hair is down. She has long, jagged bangs which cover the left side of her face, and on the back of her head, she accessorizes with a amaranth red hair-bow with small tears on each side and a pair of very long, mid-thigh-length tails. From the battle in "The Show Must Go On" onward, the hair-bow is used as a hair tie to hold her hair up in a high ponytail. Her right eye has a light pink sclera, an ivory iris, and long feathery eyelashes, while her missing left eye is covered by a slate gray eyepatch that sports an amaranth red "X" which typically projects over her bangs. Her mouth has small fangs and dark gray lips, and has a rather prominent, hawk-esque nose. Her fingernails are dark gray. Vaggi wears a short-sleeved blouse that is the same red color as her bow and the "X" shape on her eyepatch,
