ok so here are my theories. kaname might be the one adopted...or maybe yuki is? since likely kaname is a pure blood and maybe the parents are too as yuki was adopted as something other than a pure blood but something MUCH more than that or yuki is the same as her parents as kaname was adopted from a pureblood family. BUT WAIT! think about the uncle who killed the parents, why would he be going after yuki if she was the same as him being all family related? meaning maybe yuki was the one adopted...? now on the whole siblings thing, yuki and kaname are not siblings, well not related by blood atleast. i don't think it was a misprint on the last page of what kaname said either? kaname probably loves yuuki. saying he wished he was her REAL older brother because he wouldn't love her the way he does now maybe? plus yuki was a vampire all along, her mother put all of what she had as a vampire asleep if anyone remembers that. i just don't think she's a pureblood, she has to be something more...since her father would never let her out of the house and people are looking for her and all. ahh and the whole love triangle issue, i don't know who to root for anymore. i'm kinda rooting for kaname now...i mean really! but zero too ahhh. i'm still kinda confused on the part yuki saying sorry to zero a lot though. but its starting to make sense.

OKAY GUYS!! KANAME IS DEFINITELY NOT YUUKI'S SIBLING!! IM SO HAPPY. lol yuuki and kaname for the way.. Okay, remember uh what chapter 33?, but that uncle(rido kuran) who took over... *shiki*(is that corect?) body said that when the real heir comes, how are you gonna react, you fake heir? yuuki is the real heir of the kuran family, and kaname is adopted. like in chapter 35, how he said he wished he was yuuki's real brother. SO Kaname was pretending to be the kuran's heir, while yuuki the real heir was asleep. So they are not related....I HOPE XDDD. Like before in chapter 35, he said he was gonna take the princess away---->yuuki. and her father defended while her mother gave her life away casting yuuki's memories hidden. man that uncle rido sure has problems. I mean if he was after yuuki, the at least he could do is get yuuki and kaname married!! lol j/k[/quote]

so, he must have smelt yuuki's blood but it somehow turned out to smell very vampire-like.. and zero said he smelt the presence of two vampires.. (and he was DEFINITELY NOT TALKING ABOUT HIM)

I never expected Yuuki to be Kaname's sister.

"I would have been happier if I was born as her real elder brother" in page 39 ! ! ! By the way, if they're real siblings and incest happens, i wouldn't mind!

It's obvious(at least I thik) that Kaname really is a pure blood with the whole Zero and falling to Level E thing. But I think that Yuki is also a pureblood. I think that it didn't help Zero because that part of her blood was also repressed along with her memories and I think that's also why her blood semed so good. It smelled better then normal humans but not the same as a pureblood or vamp period. Also wouldn't make sense. Kuran Haruka said that she's being hidden because the founders were trying to use the blood of the purebloods for something or another. If Yuki wasn't a pure blood why would she have to be hidden ?

Kaname is pureblood. Kaname was adopted into the Kuran family. Yuuki is pureblood also and her Mom did some magic seal to repress Yuuki's memories and her blood. Kaname broke the "seal." I think he did this as a last resort because Yuuki was sufferering as she tried to remember and Rido is back from the brink of death to claim his "sacrifice." I imagine that means "eating" Yuuki so he can be a more powerful vampire, like Kaname did when he ate Shizuka. So other than Yuuki, there appears to be Rido, Kaname, and Sara who are pure blood. There's a balance of power struggle going between the council and those who want peace with humans. The council has Sara's family and Rido and the pacifists have Kaname and Yuuki. My guess is that Rido ate Yuuki's father, some other purebloods and maybe Yuuki's mother (or maybe Yuuki's mother fed herself to Kaname for Yuuki's sake -- that's my guess. As for Kaname's origin? Well, I have the feeling that he may one of the originals -- if not the original.

Well, I hope now that Yuuki is awakened she's bad-ass. That would be cool -- Kaname and Yuuki dealing some major hurt and bloodshed on Rido and that crusty old fart who is backing him. Zero has to get in some action, too, on his wayward brother. And if Yuuki is truly bad-ass, then she can bite Zero and Ichiru and have all the guys -- Kaname and her slave twins -- hellz yeah!!!. Now that's a male harem!)

But when Kaname said:"i would have been happier, if i was born as her real older brother." wouldn't that mean that he didn't love Yuuki as a lover but instead as his sister?! Even tho humans cant marry someone blood related, does that also count for vampire?!?!
