Kaname Kuran II

Kaname Kuran II was a Pureblood vampire and the true older brother of Yuki Kuran who was sacrificed by their uncle Rido in order to resurrect the ancestor of the Kuran family. As a baby, he was loved by his parents. His mother, Juri, called him a good boy. Rido's original intention was to just kill the child, but upon noticing that he shared the same name as the ancestor, he decided to instead sacrifice the child and wake up the ancestor in order to drink of his blood and get more power. But Rido only manages to wake up the ancestor, before he was attacked by him and was injured. The ancestor looked sadly at the remains of the child before he de-aged himself to the body of a child. When Haruka showed up and realized what had happened, he grieved his son's death and along with Juri raised the de-aged ancestor as their own. Hence the ancestor took over the child's identity as Haruka and Juri's son.
