 If you liked
Elfen Lied

 ...then you might like
Sola

Both animes are very action packed.Furthermore they have plenty of mystery and one male lead surrounded by many girls.Finally there are many supernatural elements that you should get used to them to watch the anime.
I watched Elfen Lied first, and I recognized a lot of similarities when watching sola right off the bat. In both series, there's a harem situation with girls that are a special creature, as well as a mysterious background to link them together.
Really similar setup, similar conflicts. The two shows end up playing out a lot differently though. If you liked one you'll like the other(Though Elfen Lied is more violent).
