Vampire knight was made from the komik jepang vampire knight in 2008 i am quite new to the series so beruang with me. if anda liked anime's such as fruits baskets you'll cinta vampire knight and if anda really loved vampire academy and the other buku in its series you'll cinta vampire knight, but if anda liked twilight i suggest anda watch it, it will turn anda off that stupid phenomena and you'll cinta vampire knight real good decent vampire material unlike twilight which is suky, zero will make anda loose your obsession with edward cullen trust me it's one of the best anime's ever made
i hope theres a third season xD
