Jizabel Disraeli

Alexis' illegitimate son and Cain's half-brother. Jizabel is a sadistic doctor who works for Alexis's secret organization Delilah. As a child, he cared for the lives of animals, but was tricked into eating his pet sheep by Alexis. Alexis also murdered his older sisters so their healthy organs could be transplanted into Jizabel's sickly body. Upon learning of this, Jizabel felt that he was unworthy of love and became depressed. Like Cain, his back is scarred from Alexis's whippings; he sees the scars as "symbols of [his] father's love". He despises the close bond Cain has with Riff because he believes that unconditional love does not exist. He was Yuki's favorite character to draw in the beginning. (Source: Wikipedia)
