Unlike the other characters in Durarara, Celty has a more down to earth personality. She is also a confident and optimistic person. In the beginning 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. Celty tends to be very close to Shinra, even though she will hurt him sometimes when he jokes around. Sometimes she will even joke with him slightly.
