Alastor is a slim, dapper sinner demon with beige-colored skin, and usually has a broad smile full of sharp, yellow teeth. He is at around the same height as his rival, Vox, with the two standing at approximately 7 feet. He sports a pinkish-red cropped, angled bob-cut with black tips at the ends and two large, black tipped tufts of hair extending from the top of his head, evoking the ears of a deer. The style has an undercut at the back, and two small black antlers protruding from the crown.

Charlie is a tall and slim-built white-skinned hellborn demon, standing at over 6 foot, around 6 and a half feet tall. She has 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.

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.

Angel has a slender build and is the tallest of the main cast of characters, estimated to stand around 8 feet with his heels on. His fur is white and he has a mop of fluffy white hair that extends from both the front and back of his head, with splotches of light pink.

Husk is an anthropomorphic avian cat demon. His look is evocative of a magician, paired with a casino referencing playing card theme. The sclera of his eyes are black, with light yellow irises and slit pupils. He has large and lengthy, red feather-like eyebrows with black vertical stripes near the tips, and a small black heart above each eyebrow.

Lucifer is a slender-figured fallen angel who sports a close resemblance to his daughter, Charlie - having the same white skin with rosy-cheeks, blonde hair with thin light coral streaks on the thicker, paler-blonde highlights,

Niffty is a rather short cyclopean sinner demon with thin pointed limbs and white skin. Her eye sports a light yellow iris, thick eyelashes, a hot-pink sclera with a yellow gradient, and a large pie eye-cut pupil. When feeling homicidal, her pupil shrinks and her eye gains black veins. Her short, chin-length red-pink hair is kept into a slightly messy and choppy 1950s bob cut with a curl on each side, and a single light yellow streak located at the top. Her mouth has sharp pale yellow teeth inside and black lips, and small hot-pink dots on each of the corners.
