Celty Sturluson (セルティ ストゥルルソン, Celty Sturluson), also known as The Black Rider or The Headless Rider, is an Irish fairy called a Dullahan who came to Japan looking for her stolen head. Her motorcycle is a familiar called a Cóiste Bodhar in disguise, which she has named Shooter and whose favored alternate guise is a headless horse.
Celty has no head and perceives via unknown sensors located in the shadows she emits from her neck and other parts of her body. The physical strength she possesses is above human, though not quite on par with Shizuo Heiwajima and Simon Brezhnev. She is also capable of producing a shadow-like, durable shadowy substance to form objects ranging from gloves to chariots at her will.
Celty lives with Shinra Kishitani and works as an underground transporter. She wears a helmet when she goes out and communicates via a PDA. She enjoys online chatting, television, and DVDs. She is a member of the Dollars and Snake Hands.
