the opening for Vampire Knight Guilty another 아니메 i suggest 당신 watch, 또는 read the 망가 which i personally prefer, (the 망가 is still being written just thought i would say that) :)
just a 랜덤 아니메 opening, i haven't seen much of the 아니메 itself but have heard its pretty creepy so if 당신 enjoy creepy messed up 아니메 with murders check this one out ^.^
