Manga I like:
D.gray Man
Claymore
Darker than Black
Vampire Knight
Superior
The Bride of the Water God
Most of Hwang Mi Ri's works
Skip Beat
Hush
A lot of manwha.<3
There are a lot more out there, but I can never ever think them up when I'm postign things like these.

Those are some of my favorites (they're kind of a Shounen/Shoujo mix xD) I pretty much like anything that doesn't have smut and ecchi in it, though I prefer those that have action,angst, and some romance in them.

Thank you in advance for any suggestions that you may post.

tokyo crazy paradise

the best security guard, EVER.

**Great Teacher Onizuka **(GTO) - i think you'll like.
Beck - also think you might like.
Yakitate !! Japan - maybe.
Full Metal Alchemist - also maybe.

and of course
Ichi the Killer (Koroshiya Ichi) - doubt you would like, for all i know its banned in your country/state/province but i think the story is really deep and can't help but recommend to anyone who hasn't read it.

Hope this helps. 😀

Can't read >_<

Berserk, Gantz, Elfen Lied

If you like romance and angst you might find Shin Angyo Onshi of interest.
