Celty Sturluson

Celty Sturluson (セルティ ストゥルルソン, Seruti Sutoruruson)

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, which she has named "Shooter." 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.

Currently her head is in Izaya Orihara's possession.

Celty lives with Shinra Kishitani and works as an underground porter. She wears a helmet when she goes out and communicates via a PDA. She enjoys online chatting, television and DVDs.

Celty is one of the few people who knows the creator of the dollars (Mikado Ryūgamine), and she seems to also be intent on helping him. She is also a member of the Dollars.

In Episode 14, it now explains that Celty is in love with Shinra, and wouldn't allow for any other Dullahans to steal him from her. It's also known that Celty's head was given to Yagiri pharmaeutical company by Shinra's father, Shingen. Back then in Ireland, Shingen used the demon blade "Saika" to separate the soul that connects Celty's head from her body.

Her voice actor is Miyuki Sawashiro.

Reasoning of her mission
The reasoning behind her need to find her head is so much of her fear of death. Celty explains in thought that she wants to control the way she lives and ultimately dies. Without her head in her possession, that decision isn't hers to make, which causes her to fear the fact that she is no longer in control of her life. She is also seen explaining in Episode 4 that another reason she desires to reunite with her head is to restore her memories and figure out why she was there in the first place.
