This series is also one of my favorites, and features a lot of nudity, sex, blood, violence, etc. It's recommended for Mature Audiences, and although the ending isn't that good; the anime itself is excellent. The manga isn't that bad either, and is still going on, even after the anime. If you've seen and liked Elfen Lied, you should like this even more. Here's a few screenshots: If you've seen it, let me know what you think of it; and if you haven't, check it out.
