I am the adopted daughter of the headmaster of Cross Academy, a 17 year old first year student, born on March 29th who wields the Artemis staff, an anti-vampire weapon formerly used by my mother. I begins as a human, a Guardian protecting the human students from the vampire students. I am a close friends with Zero Kiryu, who I becomes determined to help once I discovers he had been turned into a vampire, following which their friendship rapidly evolves. I has been in love with Kaname Kuran, a pureblood vampire, since he saved me as a young child, but my affection is later divided to include Zero as well. I am generally a kind, caring, cheerful, and comedic character, but often portrayed as not being very smart, being a poor student due to the fact that I am a guardian at night and student in the daytime, giving myself little time to study and sleep. I am often kept ignorant by other characters who know more about goings-on, which results in my character feeling guilty for being unaware of the suffering of other characters. Hino Matsuri has described me as a healing and soothing character, who exemplifies my justice side.
Towards the climax of arc one, I am revealed to be a pureblood vampire, and the Kuran princess. Juri Kuran, my mother, had sacrificed herself ten years earlier to perform a spell that would transform me into a human and had erased my memories. Kaname re-awakened my vampire side when the original threat of Rido returns to harm me. This revelation alienates Zero, but the two fight together to defeat Rido. The formerly close friends part ways after Zero tells me he intends to kill all purebloods including me, while finally revealing his feelings for me. My response is left unknown for several chapters until I admits I has an attachment to him as well as to Kaname. I had left with Kaname after advising Zero that she intended to run from him forever so that he continues to have a reason to live. My character makes little progress during the one year time skip, spending the entire time inside the Kuran mansion, dealing with vampire hunger. Following the supposed suicide of a vampire at the peace ball, I has been provoked into taking action. Bourne from a desire to be useful, I offers to help kill any pureblood intending suicide, to prevent the sacrifice of others, being completely unaware that the original death was actually murder. My mission reunites me with Zero and he ends up taking an injured me to a Vampire hunter safehouse, where I almost bites him. Upon my return home, I was finally told the truth of Kaname’s true nature and who he really is.
