Rebecca Kuran was abused, neglected, and just treated horribly by both her parents, her older brother Kaname and her twin sister Yuki Kuran. Kaname would show her some form of kindness but most of the time he would just ignore her and spend most of his kindness towards Yuki. While Yuki was shown kindness, Rebecca was shown hatred, Yuki hugs and kisses, Rebecca punches and kicks. On Yuki's and Rebecca's birthday something different happened that changed the fates of everyone including another family from a distant country. DISCAIMER: I do not own any of the characters from both Vampire Knight and Diabolik Lovers. If you have not watched either of the animes I would highly recommend you watch them.
