Hahaha. I just started watching this series from the beginning. There's so many quotable phrases like: "It's like candy, but with blood, which is so much better".
Ah! I love that theme song at the start too... it really sounds like Frou Frou, but it's not. I think I'm gonna go get that song later. "nobody knows where they might end up. nobody knows..." it's so catchy and so Frou Frou! Okay, I really need a new term for that type of music, but I can't think up of a term with such a distinct flavour.
