Yuki Kuran

Yuki Cross (黒主 優姫, Kurosu Yūkki) was born as Yuki Kuran (玖蘭 優姫, Kuran Yūkki) on March 29th, and is the adoptive daughter of the headmaster of Cross Academy. Yuki was a first year student at Cross Academy and a Prefect/Guardian. Yuki carries the anti-vampire weapon, Artemis. Towards the climax of the second arc, Yuki is revealed to be a Pureblood Vampire, and a member of the Kuran family and Kaname's younger sister. Yuki is also known as the youngest of all Purebloods.

Appearance
She was described by the Day Class boys as being stupid; 152cm (4'11") but one who eats well and considered "really really cute" by a few (including Hanabusa Aido). When she was human, she had shoulder length hair and a innocent and honest look. In her pureblood form she has long hair and a more mature look. Yuki has the typical features of the Kuran family, such as the brown eyes and brown hair. She closely resembles her mother, Juri Kuran.

Personality
Yuki is generally a cheerful and comedic girl. She is considered as a poor student because she dislikes studying and falls asleep in class, reason being she stays up all night monitoring the school grounds and night students. She exhibits a strong attachment to her close friends. Her indecisive nature and reticence can be attributed to her insecurity regarding her missing history. Prior to becoming a vampire, she had a fear of vampires which meant she rarely left the Cross Academy grounds on her own, because of the attack. She always maintained that Kaname was different to the other vampires until she witnessed him biting Ruka, but she refused to allow it to change her love for him. It did however, cause a distance between the two and revive her old fear of vampires. Yuki doesn't like to reveal her fears and wears a smile over her face instead. She is intensely protective over Zero.

Following her re-awakening as a pureblood, Yuki 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. Yuki's overwhelming fault is the tendency to burden herself with guilt over her ignorance when she learns the sufferings of other characters that they have kept secret.

Hino Matsuri described Yuki as the character who possesses her justice side. She acknowledges that Yuki is the healing and soothing character in the story.

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 love with 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 also 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 and chose to believe that his interest in her was the result of seeing her as a pet or similar.
