Carmilla Carmine is a demon and one of the many powerful Overlords of Hell. She is a supporting character, and the top weapons dealer in Hell who made her debut in the episode "Scrambled Eggs".Carmilla is a tall demoness with an hourglass build, light grey-magenta skin, and long, thick white hair with black streaks. Her hair is usually kept into a pair of large beehive-like horns by thin, ballerina-like black ribbons, but when she lets her hair loose, it reaches down to her ankles and is slightly messy. Her mouth features black lips and noticeable fangs inside, and she has a marking colored in a darker shade of her skin tone resembling a mask that envelopes her eyes, which themselves have white irises, red sclera and slit-like pupils. Her arms and hands are colored white from her deltoids down, with her hands being rather large in proportion to her body with black nails. She also has bridged wrists, instead of the alignment of her arms narrowing at the wrists like most people or demons. Carmilla wears attire similar to a ballerina, which consists of an off-the-shoulder black dress with white buttons and white stripes located down the front and at the rim of the spiked skirt, which includes magenta lining. She also wears black, waist-length stockings covered by white ballerina shoelaces. Carmilla walks on the tips of her toes in her ballet slippers, which in "Hello Rosie!" are revealed to be made out of angelic steel. She also accessorizes with a set of hooped black earrings, despite appearing to lack ears.Carmilla appears to be largely professional, though she can lose her temper, especially when Zestial is insulted or her family is in danger. Zestial claims that losing her temper is usually very unlike her, indicating that she is usually calm and level-headed. She cares about her daughters, willing to cross any line to protect them, even if it means killing an Exorcist while knowing there will be disastrous consequences for it.
