Guys! Can you tell me why Kaname and Yuuki are relatives? I haven't watch the season 2 yet but i'm so desperate. can you tell me? please...

i dont watch the anime -i read the manga- but before Yuuki was born, she had an older brother who was killed sa pamamagitan ng Rido. At the same time, Kaname was awakened sa pamamagitan ng Rido from his sleep and forced inside the deceased body of Yuuki's brother. They're known as brother and sister, however, Kaname wasn't truely born as her brother. I hope you're a Yume fan! Yuuki and Kaname are both Purebloods and deserve to be together!

K its kinda confusing but I'll try to explain so there are really 2 different Kanames, but they share the same name. just keep up. So Rido wanted to bring back the ANCESTOR of the Kurans to control him. He killed BABY Kaname Kuran who was the REAL brother of Yuki sa pamamagitan ng giving his blood to the ANCESTOR. Baby Kaname's blood brought back the ancestor Kaname. In order to restrain himself from devouring the rest of the baby he made himself turn into a baby. When Haruka(Yuki's dad) came to save HIS baby he only found the NEW baby which he took and brought him up like it was his own.So the Kaname we know was just brought up as the brother of Yuki, but not the real one. Hope that helps.

Yuuki is Kaname's sister, but Kaname is actually the ancestor or founder of the Kuran family that has been awaken sa pamamagitan ng Rido and used the body of yuuki's brother because he has no enough power to live, you can see the story about dis ancestor thing at chapter 61 2 65 dats all :)

it's so obvious the way they look y'know i could tell from the beginning ;P

Yuuki and Kaname r brother and sister and when Yuuki was little she wanted 2 marry him just like the parents were brother and sister. weird, i know but it's sweet :)
