My favourite line/scene has got to be Lydia saying this in book 2:
"Raven, you li...... ar......?"
Ahahah! After all the approaches, after everything else, to have him do that. ^^;; I also really like how Raven's character is developing so far. He laughs! ^o^ Definitely having fun with the novels so far, and only have... 13 more to read before NaNo starts. *choke*
That said, there's some definite differences between the novels and the anime that become apparent very, very quickly when reading the novels. First among them would be Ermine. It'll be interesting to see what the anime does to fill in the holes and work around things.
Anyhow, this is only a quickie post. I'll post more about this series and other things later. (Hopefully, 'later' won't be after reading all 15 books and NaNo (and JLPT) are over either! :P )
