The animation is beautifully done, but the storyline of the first episode is rather confusing. The plot is interesting, but the anime alone doesn't really explain the relationship between Taki and Klaus. It hints that they have a deeper relationship than what is shown, but without looking at the manga, you probably won't know what's going on. And the sex scenes are a bit disturbing, especially if you're not a fan of non-con (the ultra realistic kind, too). It's artistically beautiful, and a compelling story, but it's like trying to see the full picture of a puzzle with half the pieces missing.
