Shizuka Hio

Shizuka Hiou (緋桜閑, Hiōu Shizuka) The pureblood vampire who bit and turned Zero Kiryu into a vampire ; even her fellow vampires are uneasy around her. She was called the "Madly Blooming Princess". A manservant whom she loved (a former human vampire, falsely classified by the Hunter's Association as Level E) was assigned to be killed by a Kiryu vampire hunter.

Background
The "Kuruizaki-hime" that grew up in a cage, she was engaged to an older pureblood, Rido Kuran. When Rido Kuran found out that she was in love with an ex-human vampire, he put him on the vampire hunters list to be killed, saying he had already fallen to Level E. Enraged and vengeful, she attacked the Kiryuu family, killed Zero and Ichiru's parents, turned Zero into a vampire, and took Zero's twin, Ichiru Kiryu, in as a devoted servant. Being Zero's master, her blood can prevent Zero from falling to Level E, and thus Yuuki Cross risked her life for Zero to be able to drink Shizuka's blood. However, to protect Yuuki, Kaname Kuran kills Shizuka and devours her blood, leaving only a small amount for Zero to drink. Unfortunately the blood was drunk by Ichiru who arrived at the scene first. Before dying, Shizuka warns Kaname that he has killed and drunk the blood of another pureblood, therefore summoning a sinister future upon himself. She was Rido Kuran's fiancée, but they never got married due to his previous disappearance and finally her death.

Appearances
Shizuka Hio posessed the same kind of ethereal beauty and pale skin that most purebloods have. Her height was about five feet nine inches (according to absoluteanime) making her taller than most other female characters (i.e. Yuuki). She had long silvery-white hair, pass her waist and eyes a pink color similar to cherry blossoms.

Trivia
Shizuka means "calm and quiet". In Shizuka's family name, Hi is "scarlet", and ou is "cherry blossoms". Shizuka Hio is also referred to as the "Kuruizaki-hime", the madly blooming princess.
