Ruby is a self-proclaimed dork when it comes to weapons; she is quite intelligent, having designed and built Crescent Rose, her sniper-scythe. She has a very enthusiastic personality but is quite shy. She doesn't like to be the center of attention. she usually wears a black dress consisting of a long-sleeved blouse with a high collar and red trim on the sleeves, over which is a black waist cincher with red lacing up the front, and a matching skirt with red lining and a red petticoat. She also wears a pair of thick black tights that fade to red near the bottom, and black combat boots with red laces, red trims around the top, and red soles. Attached to her belt are a pocket and a row of bullets. Ruby's pajamas consist of a black tank top featuring a heart-shaped Beowolf design on the chest and long white pants decorated with pink roses.
