Celty Sturluson

Celty is a slim, tall woman who can be easily mistaken for a man. She has pale white skin, and her head is shown to have brown hair and blue eyes. In her early years, it is shown that Celty wore knight's armor as she traveled the country side with her head resting on her lap. When she immigrated to Japan, she updates her attire to match the times. For most of the series, Celty is shown to wear an all black biker jumpsuit with black gloves and shoes. With the exception of pajamas and slippers shown in the anime, all of her clothing is made from a shadow-like substance that materializes around her at her will. She also wears a yellow and blue helmet that vaguely resembles the shape of a cat's head.

Celty's personality is, ironically, one of the most normal and down-to-earth compared to most of the other characters. Although she was fairly emotionless in her early life, she has since developed a much more defined personality as she has spent more time with humans. She is generally a confident and optimistic individual, although she is not without her insecurities. Chief among these are her concerns about how people will react to her monstrous nature. In the start of the series, Celty tends to avoid most people as they usually react negatively upon realizing she has no head. However, she has recently begun opening up more to people as she encounters others who are not only accepting of the paranormal (such as with Shizuo Heiwajima or Anri Sonohara) but seem to revel in it (such as Mikado Ryuugamine or Izaya Orihara).

Aside from developing a more human personality, she has also developed a few human interests. She is shown to enjoy watching movies and television and playing video games but has developed an odd phobia of aliens, something that is used for comic relief throughout the series.

It is implied that Celty was a different person prior to losing her head. As a Dullahan, she has memories of splashing people with blood and cutting those who dared to call her a monster.
