Main Characters
Yuki Cross / Yuki Kuran
Yuki Cross / Yuki Kuran is the adopted daughter of the Headmaster of Cross Academy, a 15-year-old first year student, who wields the Artemis rod, an anti-vampire weapon given to her by Kaien Cross. She begins as a human, a Guardian protecting the vampire students' secret from the human students. Towards the end of Arc 1, it is revealed Yuki is the Pureblood Princess of the royal Pureblood family, the Kurans, and the daughter of Haruka and Juri Kuran. Following the tradition of Pureblood siblings intermarrying, Yuki was born to become Kaname Kuran's wife. As a Pureblood, Yuki not only possesses immense psychological and physical strength, but carries the rare Kuran ability to carry Vampire Hunter weapons. Her Artemis Rod is her weapon of choice, however her vampire nature morphs the rod into a menacing scythe.Yuki is extremely close to Zero Kiryuu, who she becomes determined to help once she learns he has become a vampire. Her other significant relationship is with Kaname Kuran, whom she has been in love with since he saved her from a vampire attack as a young child. She is generally a kind, caring, cheerful, and comedic character, but she is naive and careless, and performs poorly in her studies due to spending most of her nights as a Guardian, giving her little chance to sleep or study. She is often kept ignorant by other characters who know more about on-goings, which gives her immense guilt for being unaware of the suffering of other characters. Yuki is described as a healing and soothing character, who exemplifies her justice side.

On the front of the gun below the opening in the barrel you see a symbol, that is the same symbol the gun shoots to kill the vampires. Zero lives with Kaien Cross and Yuki, after being bitten by a Pureblood vampire who also murdered his family.
