Celty Sturluson is my favorite female character in Durarara and one of my favorite female characters of all time. She's different and alien, yet retains human interests. Although she is a legend with a dark history, she's shown to be humane, kind, curious, and a great friend.
I debuted as Celty at Anime Central 2011. It was my second most successful cosplay, the first being Ciel Phantomhive.
