Ichiru Kiryu

Ichiru Kiryu (錐生 壱縷, Kiryū Ichiru?) is Zero's younger identical twin brother. Ichiru failed to be a Vampire Hunter due to being a sickly boy and his lack of hunter talents. He was believed to have been killed by Shizuka Hio, but he returns healthy after revealing that he had become the servant of Shizuka and she had given Ichiru her blood to cure his chronic ill health. In spite of his desires, she does not turn him into a vampire and he remains a human. With Shizuka's death, he returns to Cross Academy as a Day Class student by the orders of the Vampire Council and his own desire for revenge for Shizuka's death. During Zero's imprisonment by the Vampire Hunters, Ichiru visits and shoots him but reveals that he attained a mortal wound in an attempt to kill Rido, because of his role in Shizuka's death. After he shoots his brother, Ichiru convinces Zero to "eat" his body so they can finally become one, as they were originally supposed to be. Zero buries him alongside their parents grave.
