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. Zestial is a very tall, slender spider-like demon with dark gray skin and lime green eyes. He wears all-black clothing, with a pitch-black cloak that covers most of his body. When Zestial unfurls his cloak, his eyes glow.
