Kuro initially seems like anything but an agent. He is a rather thin but muscular eighteen year old (though his being well defined doesn't show when he's wearing clothing). The boy has black hair and black eyes, and in many cases he is wearing a black suit, complete with black necktie and white button down under. He got the name Kuro because people know him to always wear black clothing. No one knows his real name, or his past for that matter. It is a mystery, and he likes to keep it a secret.
