Black Maria is a youthful woman of incredible size by human standards, yet still well-proportioned and slender. She is 8.2 meters tall, being slightly larger than Kaidou himself. Her long blonde hair is styled like a geisha's, with two swords notably being part of its arrangement. Her eyes are sky blue, and a strand of hair tends to dangle in front of her left eye. She has a pair of long, slightly curved red horns atop her head, wears prominent lipstick, and carries a long smoking pipe
