Sara has a duplicitous nature, appearing refined in front of her peers while having secret goals of becoming the Queen of the vampires. She refers to herself as impatient and is sadistic when she takes pleasure in giving Takuma pain. She is determined not to fall prey to the Purebloods' habit of losing purpose, which is why she is making her bid to become Queen. She surrounds herself with servants and she seems to enjoy their attention as they spoil her.

Her type of man is "Kaname" and her hobbies include shopping.

Story Plot
She first appears at a party held by the Aido family, and is greeted by the vampires present, surprising them all with her presence since it seems that she does not often attend parties. She is also an old acquaintance of Kaname Kuran knew each other before Kaname started school, and as they greet each other, she tells him that they, purebloods, should stick together.

Sara goes to the council building after Kaname's massacre and finds an unconscious Takuma after his confrontation with his grandfather, Asato Ichijo. She states that she is happy to have one of Kaname's "soldiers", since she had planned to persuade Ichijo to give Takuma to her, and is planning to use Takuma to discover what Kaname's plans are. Takuma refuses to betray Kaname, she violently tears at his already injured chest to draw blood and torment him. When both Takuma and Sara receive invitations from Kaname for the vampire ball, Sara realises that Kaname is aware that Takuma is under Sara's care and she wonders what Kaname is planning and who is more dangerous Kaname or herself.

Sara shows up at Kaname and Yuki's party, where she meets Sayori Wakaba, lending her a hand, but Zero intercedes harshly smelling blood on her. Yuki intervenes on Sara's behalf and after the humans leave, Sara comments that Yori looks tasty, Yuki asks Sara not to say such things about her friend and Sara quickly advises all the vampires present that Yori is not to be touched and says she would like to be great friends since there are only few purebloods left. When she leaves to greet Kaname, they play word games revealing that Kaname is aware that Sara has killed her fiance, Ouri at the party. Her motive was revealed to become queen of the vampires.

Sara enrols at Dahlia Academy Girls School, masquerading as Takuma Ichijo's little sister. During the guided visits she meets three girls and then she feigns a dizzy spell and asks that her 'brother' finishes the tour in her stead. Sara she enters the music suite of a human named Yukari and convinces her to become a vampire. Zero finds her at the school aware of her recent actions but unable to do anything against her because she has followed the rules. Aware of Zero's burning desire to either kill her, she further taunts him telling him he reeks of the Kurans' blood and invites him to join her since they have thrown him away.

Over the next few days, Sara quickly begins turning a lot of girls at the school with the assistance of the other school girls creating a harem to Takuma's disgust and Sara's amusement. She then visits Takuma's grandfather's factory that creates blood tablets and the president there is concerned about Sara's involvement. Takuma eventually discovers that Sara has been biting humans inlcuding the company president without permission and has them locked up in her house, but Sara catches him. Alone, Sara broke into Hanadagi-sama's castle, and obtained his heart, the organ that has the most power.

Takuma Ichijo

Takuma Ichijo describes Sara as capricious and short-tempered, but having her cute sides too. However recently, she used her command powers on him showing that he is most definitely her subordinate. She has no issue with revealing all her dark plans to him.

Ouri
Sara's fiance, who is much older then her. He rarely pays attention to Sara as he still sees her as little girl. She eventually kills him for her own ambitions, though he was ready to die.
