Ai Enma is the primary protagonist of the series. With long, flowing hair and red eyes, she is a spiritual entity with a tragic past, who lives in a world of eternal twilight with her grandmother, and is the one who receives and delivers vengeance on her clients' behalf. She normally wears a black seifuku, or sailor uniform (which is usually worn during winter months), but always wears a kimono with floral designs when delivering the vengeance of a client.<br /> <br />
