Diva
In Blood+, Diva, named by her older sister for her beautiful voice, is one of two Queens of the Chiropteran vampire race. While her sister Saya was brought up in luxury, Diva lived locked in a tower alone with rags for clothing. She developed a cruel, vicious personality and a deep thirst for blood. When Saya accidentally released her from the tower, Diva showed zero compassion for humans, delighting in drinking their blood. She and her sister then begin an epic feud that lasts hundreds of years. Diva is differentiated from her twin sister by her blue eyes, long hair and simple white gowns. For the blue trimming, sew some thin blue ribbon onto the white dress.
