Carmilla Carmine

"♪ I always thought that I would keep blood off my face. But, when that thing attacked, I had to act to cross that line and keep them safe. But, if anyone knew, then all of Hell would rise to war. And who's to say who'd survive the fray? I might lose the ones that I was killing for. So I, I'll be your keeper. Do whatever it takes, I'll make the mistakes. I'll keep you safe and keep this secret. ♪"

- Carmilla Carmine, during "Whatever It Takes"

Carmilla Carmine is a demon and one of the many powerful Overlords of Hell. She controls Hell's weapon supplies.

Appearance
Carmilla is a tall and slender, light gray-skinned demon. She sports long white hair that has been formed in the shape of large horns with several black streaks - most of them on top of the horn shape that resemble thin ribbons, while one is located on her bangs.

On her face, she has a marking that appears to be inspired by a mask, which is around her slanted-eyes with white irises, red sclera, and thick lashes protruding from them. The rest of her arms and hands are colored white, with her hands themselves are rather large in proportion to her body with black nails protruding from them.

Carmilla's attire is reminiscent of a ballerina - she wears 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 hot-pink lining. She also wore black waist-length stockings which are covered by white ballerina shoelaces, and her shoes are that of metallic ballet slippers which she walks on the tips of her toes.

During her debut episode however, Carmilla wore a set of hooped black earrings along with her main clothing.

Pilot
In the pilot, Carmilla's appearance is nearly the same, only she kept her hair down in a more loose-style, and her hands had long fingers and red claws.

Personality
Carmilla appears to be largely professional, though she can lose her temper, especially when Zestial is insulted or her family is in danger. This is in comparison to Zestial, who presents as very level-headed and equable. Zestial claims that losing her temper is usually very unlikely of her, indicated 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 all sorts of disastrous consequences for it. She even cares about Zestial, willing to protect him too.

She wants to avoid resorting to violence and avoid going to war, but at ths same time, she'll do whatever it takes to protect her loved ones.

History
While not much is known about Carmilla's past, she oversees weapon collection and management along with her daughters. Odette and Clara work under their mother in her business as Hell's top arms dealer.

During the previous extermination, Odette collects leftover angelic weapons and both her and Clara deliver their mother's products to Sinners who purchase them.

Her daughters also shown to work in the capacity of their mother's personal assistants, as shown where they all attend the meeting she arranged between fellow Overlords and assisted her in her presentation regarding the Extermination's effect on Hell's populace and how it affects them.
