The gothic-styled Sorrow is an envoy and diplomat of the Cranes. She is elegant but also somewhat prone to dreary melodramatics. The wings are part of her clothing and just for effect.
Also known as the Gloomy Crane.
She is the rightful successor of leadership of the Black Crow Triad gang. (The word "chick" refers to a baby bird, not a girl.) Unfortunately that gang seems to have been taken over by another one, so she studies kung fu so that one day she can reclaim her birthright. Although she's pink-haired and pleasant she is also a very accomplished criminal and can lift things off your person without you ever knowing.
