Shizuka Hio

Known as the "Mad Blooming Princess," this formidable pureblood vampire commands fear even among her own kind. Driven by vengeance after a Kiryu hunter murdered her beloved manservant, she launched a devastating retaliatory strike against the Kiryu lineage. During this bloody rampage, she slaughtered the parents and transformed Zero into a vampire. She also claimed Zero's twin, Ichiru, forcing him into a life of absolute devotion as her loyal servant.
