They are atually. Because their mother and father Yuri and haruka were sibling so yeah plus Yuki was born to be Kaname's wife anyway it dicho so in the manga any way.
I know Yuki and Kaname are supposed to get married and yuki was born to marry kaname but i still think that yuki and zero would make a better couple :)
actually kaname killed the real kaname and that kaname was a ancestor that was in luv with the hooded woman (no one knows her real name) plus that was his first lov *spoiler* u figure it out around chapter 60 and read on from there to figure it out...or google it
yea ppl say they are but really kaname is an ancestor nd the real brother was killed por her uncle Rido Kuran which is the older brother of yukis parents
I don't, Kaname is the proginator of the Kurans and an Ancestor. Rido sacreficed the real Kaname to bring the Ancestor Kaname back (wake him up). It didn't go so well..... In the end Kaname became a baby and was taken in por Haruka and Juri who knew the truth all along. tu don't find this out until the late volumes.
