Seeing Sakuya as a vampire sort of bothered me. To me, Sakuya is human, and her humanity is what makes her HER, if you understand what I mean. I think Sakuya is a strong enough character to remain human, seeing that becoming else isn't what should happen - unless it's something that isn't as chaotic as a vampire. Sakuya the vampire just doesn't sit well with me - or maybe it's just how it was portrayed in this.
Either way, I didn't enjoy this as much as usual - I love Sakuya but :/
