Vampires
Vampires were created thousands of years earlier following a climate change, born from humans, the first vampires were known as the founders. They were immortal beings who did not like the sun and had fast healing abilities. They would feed on the blood of humans, their bites turning humans into vampires and their obedient slaves. Vampires are divided into different levels of purity, purebloods, level A vampires are vampires born of vampire only unions whose lines have not intermarried with humans, they have many powers and only their bite will turn a human into a vampire. Level B vampires carry some human blood, but have supernatural powers and elongated lives. Level D are ex-human vampires who become level E vampires and go insane if they do not drink the blood of the Level A vampire who turned them, their master.

Ouri
Ouri was a pureblood, first name unknown who only appears in flashbacks. Ouri was found dead at the hand of a vampire hunter who was also found dead, by her own hand. The murder occurred at the vampire ball and investigated was ended prematurely and passed off as a suicide, however, the pureblood was murdered by Sara Shirabuki, his fiancee. Sara bit the hunter, turning her into a vampire, then compelled her to kill Ouri, then herself afterwards. Ouri had known that his life was going to end, so he accepted this murder as he was ready to die. Yuki, believing the story about the suicide, was investigating on how to stop the rest of the purebloods from using innocents as instruments of suicide.
Rido Kuran
Rido Kuran (玖蘭 李土 Kuran Ridō ) is a pureblood vampire, Shizuka Hio's former fiancé, Senri Shiki's father, and elder brother to Haruka and Juri Kuran. He was the main antagonist of the story. Rido possesses eyes of two different colors (crimson and blue) and when his soul is transferred to a different body, that body has the same eyes. Shortly after the birth of Juri and Haruka's first son, he took the baby and sacrificed it to reawaken their ancestor, Kaname in order to drink his blood. However, upon Kaname's awakening, his severe hunger led him to attack Rido, leaving him incapacitated. He was arrested and held by the council. However, he was set free and ten years ago, seeking to take Yuki, Rido killed his younger brother, Haruka, with an anti-vampire sword. Kaname attempted to kill Rido, but found he was unable to as Rido was his master.[14] Instead Kaname reduced Rido to the state where he required another pureblood vampire's blood in order to revive fully.
Aided by the Ancient Vampire Council and the Hunters' Association, Rido manipulates events from the shadows for ten years by transferring his soul to other bodies and taking control. Rido continued to meddle in the life of Shizuka, by adding her lover's name to the hunter's list. Rido takes possession of Shiki's body and he goes to Cross Academy. After revealing himself, Kaname revives Rido's body using his blood. Following his true body's revival, Rido's servants sense his revival and begin to attack the school students in order to capture prey for Rido to feed on. Rido attempts to compel Aido to feed upon him, but is thwarted by Yuki. Seeing Yuki's resemblance to her mother, his sister Juri, Rido changes his original desire from eating Yuki (in order to gain power) to taking Yuki as his lover as a replacement for Juri,[15] who he loved but who had never wanted him, having chosen Haruka over him. Rido's life seemingly came to an end when he was defeated by Zero, with the help of Yuki, but it was recently revealed that Rido did not completely die. Instead, he now exists as a phantasmal 'fragment' of consciousness attached to Kaname, who can only be seen or heard by Kaname.

Sara Shirabuki
Sara Shirabuki (白蕗 更 Shirabuki Sara ) is a pureblood vampire who first appears at a party held by the Aido family, stating to Kaname that "We purebloods have to stick together". She is around Kaname's age, slightly older than Yuki. She is called on by vampire society to stop Kaname when it is assumed that he has gone mad after killing the Vampire Council.[16] Sara found Takuma Ichijo and says to herself that he "will be useful to get the information on what Kaname's plans are".Takuma serves as a servant to Sara, following her orders. Sara is currently starting to go to school, using the excuse of her being ill and unable to attend school to explain her older looking appearance. Her ulterior motive is revealed in Chapter 56 when she says "I will be Queen" to Ichijou. She also confesses that she took the life of her fiancee, Ouri. It is revealed that Sara is creating vampires from humans, a taboo, to form her own army of vampires.
Shizuka Hio
Shizuka Hio (緋桜 閑 Hiō Shizuka ) is the pureblood vampire who bit Zero; even her fellow vampires are uneasy around her and refer to her as 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. 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, in as a devoted servant. She was originally Rido Kuran's fiancée, but they never married due to his disappearance and finally her death.
Because Shizuka's blood can prevent Zero from falling to Level E, Yuki once had risked her life and humanity for Zero to be able to drink Shizuka's blood. However, to protect Yuki, 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 for drinking the blood of a Pureblood, when he is one himself.
