Ai Kuran

Ai Kuran is the only daughter of Yuki Kuran and Kaname Kuran. She is also the last Pureblood of the Kuran family. She appears at the end of Chapter 93 with her younger half-brother to give Yuki's final message to Kaname when he wakes up from his 1000-year slumber.

Appearance
Ai has the typical traits of a Kuran. She has wavy long black hair and red-brown eyes similar to her father, Kaname.

It it noted by other characters that she wears a stiff expression like her cousin, Senri Shiki.

Personality
Although not much is known about Ai, Zero has stated that, unlike Yuki, she is more mature for her age. In the Extra "I Like You", she is shown to adore Zero as her "Father" and most of the time he reminds her that Kaname is her actual father. However, this changes once she reaches high school and openly admits that she is indeed in love with Zero romantically. However, she keeps quiet for her mother's sake. Ai does, in fact, tell Ruka her feelings. Ai was a very observant child and seemed more aware of things happening around her than the adults were aware of. Ai has a good typical sibling relationship with her brother Ren as they are shown scolding one another. A young Ai was much more hyperactive in nature than her level-headed attitude as an adult.

Story
Ai appears at Kaname's resting place along with her younger half-brother and her mother Yuki. Ai and her younger brother watch their mother give her life to Kaname to turn him human. She passed a message from her mother to her father "I want to give to you, whom I love, the world that I saw when I was a human". Ai and her brother watch over Kaname when he wakes up as a human.

She appears in extra Life as a baby. She was born four years after her mother Yuki left Cross Academy. In the last extra I Like You, she and her brother tell Kaname what happened in the last thousand years and about the efforts of Aido, Yuki and the others but he appears not to be listening to them to which Ai and her half brother remember that Kaname had his memories sealed along with his vampire side so the past does not matter to him. Ai tells her brother that she does not want Kaname to not know about what transpired during his thousand year sleep and appears upset. She and her brother are then hugged by Kaname who asks them to tell him more about what happened in the past one thousand years.

Yuki Kuran
Yuki Kuran was Ai's mother. In the last chapter Ai stays by her mother's side before she sacrifices her life to turn Ai's father Kaname into a human. It is seen in Life, that the reason Yuki was able to survive her grief of Kaname's death was because of Ai's birth. As noted in later chapters when Ai is still a child, Yuki and Ai share a dear and lovely relationship. When Ai becomes older, their relationship remains strong, though slightly distant, because of Ai's love for Zero that she was forced to conceal for her mother's sake.

Kaname Kuran
Kaname Kuran is Ai's father. In the chapter.  'I Like You ', after she and Ren are there to greet him after Yuki has awakened him by giving her heart to him, he hugs both of them. Ai is shown to be happy with finally having reconnected with her father and though not much has been revealed with Vampire Knight Memories having only begun, it's noted that Ai and Kaname are bound to have a close relationship.

Zero Kiryu
Zero Kiryu was Ai's father figure as her real father, Kaname, was dead. In "Life" he meets Ai for the first time. He puts out his hand and teased her for making her mother attack him and she latches on to his finger. Before I Like You and after Life, Zero started taking care of Ai whenever her mother was busy with Vampire Society. In I Like You, Ai adores Zero and calls him her father to which he reminds her that Kaname is her actual "father", but she persists by saying that he is her "father" too. In her teenage years Ai admits that she is in love with Zero and Ruka stated that it was painful to watch the person she wants as her "prince" love another. This made Ai heartbroken and frustrated so she continues to ask Zero and Yuki for a little sister that she can have all to herself to feed from.

Ren Kiryu
Ren Kiryu is Ai's younger half-brother. They both get along very well and care about each other dearly.

Trivia

 * Ai's given name is written with the Kanji for love (愛, ai). This was most likely down by Hino-sensei to show that Ai was a product of true love from Kaname and Yuki.
