Zero Kiryu (錐生 零, Kiryū Zero?)
Yuki's childhood best friend. Zero is also a Cross Academy Guardian and likewise on the disciplinary committee. Yuki has cared about him as a close friend ever since he was brought into their home (the Headmaster's). His family, one of vampire hunters, was murdered by the pureblood vampire Shizuka Hio when he was young. He harbors a deep hatred for vampires and claims to have taken on the role of Guardian to learn how to hunt them better. In truth, Zero was bitten during the attack on his family and therefore was turned into a vampire, something that has been kept secret even from Yuki until his vampiric urges began to surface and became uncontrollable. As Zero's body rejects the blood tablets that most vampires take to control their hunger, Yuki began letting him drink her own blood, which helps his thirst for blood, but he is ultimately to become a Level E vampire. The story implies that Zero may harbour romantic feelings for Yuki. In chapter 35, he discovers Yuki is a vampire, and in chapter 37 he aims his gun at her, which leads to Yuki telling him her vampire side "ate" her other side. He almost kissed Yuki twice showing that he has feelings for her. Zero is currently being locked up by the Hunters Association.
Zero's weapon is the gun "Bloody Rose," given to him by Chairman Cross. He made Yuki promise that if he becomes a Level E vampire, she will kill him with the "Bloody Rose".
