Kaname Kuran

Kaname Kuran A pureblood vampire who saved Yuuki from an attack by another vampire when she was 5 years old. Kaname is the class president of the Night Class, both feared and respected by the other Night Class students. While he is cold and authoritative towards his contemporaries in the Night Class, he is always kind and sweet to Yuuki. He has shown that he cares for Yuuki in a romantic sense ever since he saved her. He is also Yuuki's fiancee and "so called" brother. Apparently, he allows Zero to live because he knows his death would sadden Yuuki and because when he cannot protect Yuuki, he knows that Zero will be there. However, he has another reason for keeping Zero. Kaname also asked Yuuki to become a vampire and live with him for all eternity by his side, but manages to stop himself from biting her. He is both jealous and angry with Zero for biting Yuuki and endangering her life. Later on, he bit Yuuki in order to awaken her and kisses her to transfer his blood into her body. He also knows the pureblood who bit Zero, Shizuka Hiou, and later kills her before drinking her blood to gain power with which to protect Yuuki, in spite of it being a terrible taboo. It has been revealed in Chapter 38 that Haruka and Juuri Kuran had a son, but his soul was killed by Rido Kuran and Kaname's soul was put into his body. Kaname was the ancestor of the Kuran Family thus resurrected by Rido from the grave, who became his 'master' making him unable to kill Rido. (Compare to the relationship between Shizuka Hiou and Zero). Juuri and Haruka, Yuuki's parents, raised Kaname as Yuuki's brother, although Kaname never fully became 'their son'. Yuuki and Kaname planned to marry as children, following the example of Juuri and Haruka who were also brother and sister and married. At one point, Kaname allowed Zero to drink his blood to stave off insanity, preventing Zero from turning into a Level E for the time being.
