Six is a half-vampire and half-human from the Blackburne vampire clan, the seventh son of the Blackburne clan's master. He has long black wolf-cut hair with red snake-like pupils alongside black and red clothing. He became a vessel for the demon "Sorath" due to a sacred ceremony but has been exiled from his clan after killing the clan elders. Sorath can be witty, intelligent but also manipulative and arrogant. Six is also the youngest master of the magic tower after making a name for himself.
