Yuki Kuran

Yuki Cross/Yuki Kuran (黒主 優姫/玖蘭 優姫 Kurosu Yūki/Kuran Yūki) is the main protagonist of the series. She is initially portrayed as a Human but is later revealed to be a daughter of the Kuran family, one of the remaining seven Pureblood families. When her brother and fiancé, Kaname Kuran goes 'mad', she becomes the acting Head of the Vampire Society.

Appearance
Yuki is a short, slender, teenage girl with large red-brown eyes and short dark brown hair. She wears the trademark black uniform of the Day Class, additionally with a white armband carrying the mark of a red rose. Additionally, under her skirt, attached to her left thigh, Yuki carries her weapon, Artemis Rod. Upon her reawakening as a Pureblood vampire, Yuki's hair grows over twice as long as it originally was, now reaching her waist. But in chapter 83,Yuki cuts off her hair using Artemis to its former bob style to show Kaname she is disappointed with his change in character and is going to start taking action. In addition, she develops a more mature and serious personality, reminiscent of her mother Juri Kuran; though she maintains a kind gaze, apparently similar to that of her father's. Yuki's body, although still petite, also becomes more perfectly proportioned.

As a young child, Yuki's hair was quite long, reaching her mid back.

Personality
Yuki is generally a cheerful and comedic girl. She is considered a poor student because she dislikes studying and falls asleep in class due to the fact that she stays up all night monitoring the school grounds and Night Class students. She exhibits a strong attachment to her close friends, especially Sayori and Zero. Her indecisive nature and reticence can be attributed to her insecurity regarding her missing history. As a human, she has been seen as loving vampires but deep in her heart she feared all vampires (because of a vampire that attacked her when she was little) except for Kaname Kuran.

Because of this fear she rarely left the Cross Academy grounds on her own. Yuki doesn't like to reveal her fears and disguises it with a smile over her face. But Zero, having grown up with her for four years, is always able to tell when something is bothering her, making it hard for her to hide things from him and vice versa.

Following her reawakening as a Pureblood vampire, Yuki shed the fears she once retained. When a situation asks, she can put in an authoritative face as is expected of a Pureblood Princess. As a result, she has grown more emotionally mature and thoughtful. Yuki's overwhelming fault is the tendency to burden herself with guilt over her ignorance when she learns of other people's sufferings that they have kept secret.

Yuki's favorite subject is Physical Education and her favorite food is ginger pork stir fry set, as well as parfaits.

History
Yuki was five years old when Rido Kuran attacked the Kuran Family household seeking to take her away. In order to protect her, Juri sacrificed herself to seal Yuki's vampire side and erased her daughter's memory. Yuki's first memory is that of Kaname saving her from a Level E Vampire who tried to devour her blood while alone on a snowy day.She grew up as a human in the care of Kaien Cross, who also adopted her. Despite no longer remembering Kaname as her brother, he remained an important person in Yuki's life, becoming her much beloved saviour whose visits she always looks forward to, eventually leading the teenage Yuki to develop intimate feelings for him.

Despite having her memories sealed, as a child Yuki experienced constant nightmares, a problem which continued nightly until Zero Kiryu joined the Cross household. As a result, Yuki formed a strong attachment to him. She found comfort in helping Zero with his personal nightmares and unofficially appointed herself as his guardian, entering his room nightly to make sure he slept soundly, and constantly worrying about his well being. Shortly after Zero's arrival, another change occurred between Yuki and Kaname's relationship. The closeness they once shared was lost after she witnessed Kaname feeding on a vampire classmate Ruka, an act which both frightened Yuki and reminded her of the difference between humans and vampires. Now keenly aware of the futility of her feelings,Yuki chose to distance herself from Kaname. Still, her admiration and longing for him remained. Furthermore as she grows and matures, Yuki has to confront the secrets of the Purebloods (including Kaname) and her existence. It is noticeable that she looks exactly like her mother but has been implied to have the tenderness of her father.

Powers and Abilities
Like all Pureblood vampires, Yuki has immortality and the ability to heal from anything excluding anti-vampire weapon wounds to the heart or head.Yuki has demonstrated the following abilities, though most of her abilities are instinctual and uncontrolled:
 * Telekinesis, breaking windows on the few occasions when she experiences strong emotions.
 * Ability of flight using a pair of wings on her back made of blood that resemble butterfly wings.
 * Ability to interfere with memory blocking through touch and includes breaking memory spells on herself.
 * Ability to wield anti-vampire weapons both as a human and as a vampire and transform the Artemis rod into its scythe form, like her mother did.
 * Ability to have her blood cure people's hallucinations, illness and disaster.

Equipment
She wields the Artemis rod and can turn it into a scythe. This rod was given to her by Kaien Cross.

Kaname Kuran


Kaname is Yuki's admired savior,her Pureblood brother,fiancé and ancestor. They have a long and complicated history. At times, it could be even viewed as mysterious which leads their relationship to be ambiguous. Although Yuki seems to love both Kaname and Zero, she still chose to leave Cross Academy with Kaname Kuran, as she loved Kaname whom she considers is the start of her world. After Yuki found out about Kaname's plan, she decided to stop him from killing other Purebloods and teamed with Zero and the Vampire Hunters Association. When Kaien Cross went to meet up with Kaname, it is revealed that Kaname planned to give his life to create new weapons for the humans against the vampires, much like the Hooded Woman had done. Yuki reveals herself, having followed her adoptive-father at his insistance, begging Kaname to not do so. Kaname and Yuki are reunited, Kaname feeling guilty over leaving her. Even after he insists that he will not leave her, again, she refuses to let him go, calling him a "LIAR", and telling him that every memory she had of him since he rescued her from the Level-E Vampire (the night her memories were erased by her mother, Juri) were all lies. Kaname proves his devotion to Yuki by taking her back to their room in the house she was born in and sleeping with her.

Zero Kiryu
Yuki and Zero were childhood friends, allies who became enemies and finally into an uncertain wary relationship as they both try to figure out where they stand. Even though it was only stated once, Yuki does admit to Kaname that part of her belongs to Zero. Whether this is romantic-wise or not, has yet to be proven although some fans believe that it is of a romantic nature due to a Pureblood's bloodlust only being quenched by a lover's blood. Yuki is shown sated by Zero's blood, she mentions he is the one she never thought she would attain blood from. Yuki does have some feelings for Zero but locks them up deep in her heart. Yuki erases Zero's memories of the human Yuki so Zero won't feel that bad when she turns Kaname to human.

Sayori Wakaba
Sayori Wakaba is Yuki's best friend, roommate, and Yuki affectionately calls her Yori. Yori often worries about Yuki and her prefect duties, telling her she needs to rest and jokes about her being a vampire due to Yuki's sleeping habits. Yori knows that Zero has feelings for Yuki and asks him about them, but Yuki most of the time has no idea what she's talking about. When Yuki was reawakened as a vampire and vanishes, Yori is worried and tells Yuki that no matter what they will always be best friends. She has also told Yuki that she isn't scared of her despite Yuki telling her that she could have bit her.

Hanabusa Aido
Aido was Yuki's antagonistic senior classman who was jealous of her relationship with Kaname. After Yuki was revealed to be a Pureblood Vampire, Aido ends up becoming her tutor and mentor. This is further enhanced to the status of protector as the series progresses. Though their new relationship is on a new, professional level, the two have demonstrated a better and closer friendship.
