Shizuka Hio

Shizuka Hio (緋桜 閑, Hiō Shizuka?) was the pureblood vampire who bit Zero Kiryu; even her fellow vampires are uneasy around her and refer to her as the "Madly Blooming Princess" or "Kuruizaki-hime". 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 the Kiryu vampire hunters. Enraged and vengeful, she attacked the Kiryu family, killing both parents, biting Zero (which subsequently turned him into a vampire), and taking Zero's twin, Ichiru, as a devoted servant. She was originally Rido Kuran's fiancée, but held strong feelings of hatred for him, and it was revealed that she wanted more power to kill him herself. Later in the manga, when Rido spoke of her death, he metioned that it was a relief and that when alive, she had refused to obey/cooperate with him. They never married due to some unknown reasons.

Because Shizuka's blood can prevent Zero from falling to Level E, Yuuki once had risked her life and humanity for Zero to be able to drink Shizuka's blood. However, to protect Yuuki, Kaname kills Shizuka and drinks her blood, leaving only a small amount for Zero to drink. Unfortunately the blood is drunk by Ichiru, who arrived to find Shizuka first. Before dying, Shizuka warns Kaname that he will live in darkness and has summoned a sinister future for himself by drinking the blood of another Pureblood. Maria Kurenai was one of her distant relatives.

Appearance
Shizuka Hiou posessed unnatural beauty like all the other purebloods. She appeared to be in her late twenties. In the anime, she had straight long silver/snow white hair and eyes that were the pink of sakura (cherry blossoms). Shizuka Hio was 5 feet 9 inches, making her one of the taller female characters in the anime/ manga. She was always shown clad in traditional japanese clothing, such as the kimono. She usually appears calm and composed, and smiles as if amused when taunting/talking to Zero.
