Character outline
Yuki has the rare pureblood ability to use an anti-vampire weapon, which is an ability that the Kuran family posesses. In her capacity as a Guardian, she was responsible for the nightly duties of monitoring and protecting the Day Class. Yuki is mocked for being flat-chested, and resembling a young boy. Following her transformation back into a pureblood vampire, her hair grew waist length, she grew taller, and appeared thinner with a defined waist, and more angular features. Yuki bears a striking resemblance to her deceased mother Juri, but in look and has a similar smell of sunshine coming from her. She was described by the Day Class boys as being small; 152cm(4'11") but one who eats well and considered pretty cute by a few. Including Aido who took the time to ask the her fellow boy class mates, which indicates that he agrees." When Yuki confronts her uncle, Rido immediatly recognises Juri in Yuki. "I have been waiting for you Juuri!." Then Kaname says, "You have grown into a beautiful girl Yuuki. Seeing your'e strong and happy. I am very happy!...Nothing can make me happy as seeing you grown up!" Then he states that she is the most important person in the world to him. Kaname thinks of Yuki to be very beautiful, because as a vampire he states while destroying the council, "Yuuki, this world is not beautiful. The most beautiful thing is your eyes which can stop this twisted world. Yuki's best friend is Sayori Wakaba, whom Yuki calls "Yori-chan." Sayori is her roommate, too.

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. 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 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 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.

After viewing the horrifying death of the real brother and how the ancestor reverted himself into a baby, Yuuki gently reassure Kaname that the only Kaname she knows is him and that he can tell her anything without holding back. Yuuki tells Kaname she wants to know about his past, not just about the awakening but his past as the ancestor. As she goes deeper into his memories she sees them as children again in the snow after the death of their parents. They were being pursued as they escaped and Kaname who was carrying an unconscious Yuuki, set her down so that he could fight the enemies so he could take her to Cross' place for Yuuki's safely. Kaname looks so sad as he says that the next time she wakes up, she'll look at him with the eyes of someone that don't remember him.

She later wakes up to find herself in the same spot he put her but in her Cross Academy uniform and her hair short. She falls into Kaname's memories of his past and reflects on the beginning of the vampire race and on how Kaname and Zero are just alike.
