Did you know that the Kuran Family actually had two daughters instead of just one? Yuuko was Yuuki's little sister, but despite that fact, they were treated in ways which contrasted very much. Yuuko was ignored, hurt, abused whilst Yuuki was showered with love, good attention and care. Very different is it not? Yuuko always believed they would someday change but one day, she had enough and ran away from that cruel family but her life wasn't going to be completely unrelated to the Kurans afterwards. What will happen when she encounters the siblings and more vampires afterwards? ---- Tiny little disclaimer- I don't own Vampire Knight.
