Edit: Added a new screenshots page for Karneval~
As I mentioned before, the storyline for Karneval is really good- it's difficult to get really into at the beginning because of all the early use of complicated terms, but eventually as I progressed through the episodes, more of it started to 'make sense'.* The fact that I'm currently showing a huge preference towards the supernatural genre doesn't help put me off the anime because it's got a few, ah, graphic parts.
And no, when I say supernatural, I don't mean vampires and all the other clichéd supernatural beings with "sparkling" characteristics that recent books *cough, cough* contain--
*Not to mention the amazing art style- I'm sorry, call me prejudiced or whatever suits, but when it comes to watching anime, I can't stand watching one which I don't like the art style.
