Kaname Kuran, a pureblood vampire, saved Yuki from an attack by another vampire when she was little. He is the class president of the Night Class, much feared and respected by the other Night Class students. While he is cold and authoritative towards his fellows in the Night Class, he is always kind and sweet to Yuki. He has shown that he cares deeply for Yuki, and loves her in a romantic sense. He allows Zero to live because he knows his death would sadden Yuki, and because Zero is useful. He is both jealous and angry of Zero for biting Yuki and endangering her life. Kaname has been raised as Yuki's older brother. At a young age they had pledged to marry each other when they grow up, just like Haruka and Juuri, who were siblings yet married to each other. It is common for pureblood siblings to marry as it is essential to keep the bloodline pure. Also, a fact yet to be revealed to Yuki is that Kaname is not her "true brother". He is actually the ancient ancestor of the Kurans, and Rido is his master who awakened him from his grave, and put the ancestor's spirit in the 'real' Kaname's body, making him unable to kill his 'master'
