Yuki Kuran

Yuki Cross/Yuki Kuran (黒主 優姫/Kurosu Yūki 玖蘭 優姫/Kuran Yūki? ) is the adoptive daughter of the headmaster of Cross Academy. Yuki is a first year student at Cross Academy and is a member of the school's disciplinary committee, which is a Guardian for Cross Academy. In her capacity as a Guardian, she is responsible for the nightly duties of monitoring and protecting the Day Class. Yuki carries the anti-vampire weapon, the Artemis Rod.

Personality
Yuki is generally a cheerful and comedic girl. She is considered a bit stupid and a poor student. She exhibits a strong attachment to her few close friends. Her indecisive nature and reticence can be attributed to her insecurity regarding her missing history. She has a fear of vampires which means she rarely leaves the Cross Academy grounds on her own, but she doesn't like to reveal her fears and wears a smile over her face instead. She is protective over Zero and fears the fact that he might become a level E. Following her re-awakening as a pureblood, Yuki has shed the fears she once retained, but her personality has not changed much and when a situation asks, she can put in an authoritative face as is expected for a pureblood princess.

Appearance
When Yuki was a human, she was around 5 feet tall, and possessed short brown hair. She had red brown eyes and appeared rather flat and didn't have curves which made it look like she had a young boys type of figure. When she was transformed back into a pureblood vampire, her hair grew waist length and she appeared to have grown a little taller and she appeared thinner because of this with a much more defined waist giving her that supermodel quality. She looks much more mature than her human self and possesses the typical features of the Kuran's maroon eyes and light auburn hair. Yuki bears a striking resemblance to her deceased mother Juri, who appeared more mature and had curly brown hair but she has Haruka's "soft" gaze.

Background
Yuki was approximately 5 years old when Rido Kuran attacked the Kuran family seeking to take Yuki. To protect her daughter, 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 vampire. Yuki grew up as a human in the care of Kaien Cross, who also adopted her. Kaname stayed as a presence in Yuki's life whom she constantly looked forward to seeing and missed leaving, falling in with love him.

Yuki as a child had troubled nightmares nightly until Zero Kiryu joined their household and Yuki formed a strong attachment to the boy. Yuki's relationship with Kaname became distant after she witnessed his vampire nature as he fed on a vampire classmate and as a human, Yuki believed she had no chance with Kaname and began to distance herself from him, but her admiration and longing for him remained.

Yuki's best friend is Sayori Wakaba whom Yuki calls "Yori-chan". Sayori is her roommate, too.
