Kaname Kuran (玖蘭 枢, Kuran Kaname) is another male protangist and is the pureblood vampire who saved Yuki from an attack by another vampire when she was five years old. He is the class president of the Night Class, both feared and respected by the other Night Class students. As a pureblood, he is capable of controlling lesser vampires, but chooses not to exercise his powers, thus earning the respect of other noble vampires. Kaname shares the Chairman's hopes for a peace between vampires and humans and worked with the Chairman to create the Night Class at Cross Academy. Despite Zero's distrust, Kaname's presence keeps the Night Class in check. Normally a stoic and authoritive individual, Kaname's kind and gentle attitude toward Yuki has puzzle his fellow vampires. He expresses discontent with Zero for biting Yuki and endangering her life. Kaname tells Zero that he only allows Zero's existence by Yuki's side to ensure her safety and is envious that he cannot protect her himself. He eventually reveals to Yuki that he loves her.
As he kills Shizuka Hio, Kaname promises her that he will destroy the being that ruined the destiny of the purebloods and drinks her blood in order to gain power to protect Yuki, though he leaves some of her blood to save Zero. Kaname makes repeated offers to Yuki to allow her to remain by his side, including offering to make her a vampire and asking her to become his lover when she presses him for information concerning her forgotten past. He also convinces Zero to drink his blood to stave off insanity, slowing Zero's decent to a Level E vampire. Kaname eventually reveals that this act was one of many steps required to prepare and strengthen Zero so that he can kill Rido and free Kaname from Rido's curse.
As Rido's presence becomes increasingly apparent, Kaname bites Yuki in order to awaken her vampire nature and feeds her his blood to restore her memories as a Kuran and as his sister. He reveals to Takuma Ichijo that he is not Yuki's true brother, but the first king and founder of the Kuran family who had been revived by Rido Kuran. As such, Kaname is unable to kill Rido, his "master", and was only able to severely injure and incapacitate him when he tried to take Yuki from the Kuran family. As a child, Juri and Haruka Kuran raised Kaname as Yuki's brother, in place of the son that Rido took, and Yuki and Kaname planned to marry when they were children, following the example of Juri and Haruka who were also brother and sister and married.
When Rido is revived, Kaname plans to take Yuki away from Cross Academy, fearing for Yuki's life. Yuki's refusal to comply with his plan upsets him, but she kisses him to console him and convinces him to leave her and complete his mission. He goes to the Vampire Council and kills all the summoned members except Asato Ichijo.
