Also known as "The Black Rider" or "The Headless Rider", she is a Dullahan from Ireland who came to Japan looking for her stolen head. Her motorcycle is actually a horse in disguise. She has no heart and perceives via unknown sensors that are not located on the head. The physical strength she possesses is above human, though not quite on par with Shizuo Heiwajima. She is also capable of manipulating a shadow-like, durable substance to form objects ranging from gloves to chariots at her will.
