She is called on by vampire society to stop Kaname when it is assumed that he has gone mad after killing the Vampire Council. Sara returns, 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.

When Takuma refuses to betray Kaname, she violently tears at his already injured chest to draw blood and torment him. But later, when both Takuma Ichijo and Sara receive invitations from Kaname and Yuki for the vampire ball, it appears that Kaname knows Takuma is under Sara's care and thinks that she is not a threat to Takuma's existence. Their is also had no exchange of hostility or fear between them as Sara handed Ichijo his invitation. She also seen wondering what Kaname is planning and who is more dangerous Kaname or herself.

She later appears at Kaname and Yuki's party, where she meets Sayori Wakaba, who is Yuki's friend, lending her a hand. But Zero grasps her in time, thinking she might harm Sayori. Yuki interrupts when she senses a human and realizes it is her best friend and meets Sara. Sara says she would like to be great friends since there are only few purebloods left. When she leaves to greet Kaname, both Zero and Yuki sense a smell of fresh blood coming from her which later in 55th Night proven to be the blood of her fiance. Her true motive was also revealed, to become queen of the vampires. Sara's fiance is revealed to be the mysterious Pureblood Ouri-sama, who is much older then her as he rarely pays attention to Sara as he still sees her as little girl. Interestingly she has shown other sides of herself to Takuma Ichijo, who reveals to just even though Sara capricious and short-tempered, she also has cute sides, too.

In 51st Night, Sara reveals that she had killed her fiance.

She is later seen enrolling into Dahlia Academy Girls School, masquerading as Takuma Ichijo's little sister. When being guided by the rector, after passing three girls headed to the music department, she fakes having a spell and asks that her 'brother' finishes the tour in her stead. Once they left, she follows the girls and after telling them what she was, she drinks their blood, and shares some of her own, so they don't turn into level E's. After leaving the school with her new found 'friends', she runs into Zero who is ready to kill her and the other girls. But she tells him that she did everything by the rules and therefore he couldn't execute her or her friends. She then tells him how she can see his burning desire to either kill her or the other purebloods. She also mentions how much he reeks of the smell of a pureblood vampire and questions how much blood the Kurans gave him. She continues to taunt him by saying how they have thrown him away like an abandoned dog, and how she wouldn't mind taking him in. He responds by telling her to disappear, saying how she shouldn't piss him off more then this. Her power is currently unknown but it is seen that when she got angry she melted the window.
