Hyakuya family invited by the royal family of Tepes. What happened when Hyakuya Yuichiro, the heir of Hyakuya family, meet Asura Tepes, the vampire prince? Sure nothing would go wrong, right? This is an AU that set in the same world, but without the apocalypse, the seraph experiment or the demons, which mean, the vampire still exist, but human and vampire lives their lives without a war. (Special note for those who already knows the identity of the First Progenitor: On this AU, the First Progenitor is NOT the same guy as in the canon story, because I don't want to put a spoiler by using the canon First Progenitor. After all, I want this story to fully focused on the vampires)
