Yuuki Cross
, 黒主 優姫
Yuuki is a student at Cross Academy and serves on its disciplinary committee (also known as the public morals committee in Japanese). She was adopted by the headmaster, who took her in after she was attacked by a vampire ten years ago. Despite losing all memory of her past life, Yuuki has developed strong feelings for Kaname, one of her classmates at Cross Academy. Although she witnessed his vampiric nature when he bit Ruka, she remains deeply in love with him. Recently, Yuuki has allowed Zero, a childhood friend, to drink her blood in an attempt to save him from madness. She is known for being cheerful and easygoing, and thanks to her work as a Guardian, she is able to remain calm under pressure. There have been hints that Yuuki may be special due to the fact that vampires are particularly attracted to her blood. Her weapon of choice is an extensible staff called the Artemis Rod, which was given to her by Headmaster Cross.
