.Hack/Sign looks at SAO series while slowing shaking its head and backing away before it gets contaminated.
With regards to manga recommendations for elfy, I could point out Wolf Guy(completed), though that is some mature stuff right there, or Blood and Steel(on going), if a Chinese based anime with nice art gets you going, or City of Dead Sorcerer(on going), if a Korean based anime that is webtoony floats your boat, or Ubel Blatt(on going), if you want something that reminds you of Berserk, or The Ravages of Time(on going), if you want something of historical where the gap in known history is left to the creative mind of the creator and it's based on the Three Kingdoms with great art and it is lengthy, or Zetman(almost completed), if you want something that has been partially done in anime, or The Breaker: New Waves(on going), if you want something more popular that you might've read already, or... a number of other titles, but I don't know what you like, and I haven't read too much to give you ones that aren't somewhat popular at least.
