Lest Karr has a short stature and an appearance of a young male with dark-rimmed eyes. His hair is styled into two braids that trail down his back. The right half of his hair is red velvet while the left half is white. He has bangs that cover part of his face. Just like most true vampires, he has fangs, red eyes, and pointed ears. He wears a small decorated top hat with blue feathers to match his dark, button-up coat, and he wears a white dress shirt underneath.
