dark anime

[20potter]

I am not sure if this is where it should be put but here goes. I am looking for a dark anime, that is more then 13 episodes long, that I have not watched.
animes similar to:
death note
higirashi no naku
phantom requirum
d gray man
code geass
black lagoon
bassilisk
monster
witch hunter robin
witch blade
blood
elfinlied
bleach
those are most of the ones I have watched. there is a few more floating around for sure. I want plenty of action and a good story line, not to confuseing. thankyou

Gantz might fit into that category. It's quite violent, and in many ways a little like Elfen lied. More confusing story though.

Watch basilisk. Very very dark and grimy.

Darker than Black is a personal favorit of mine, and while i find it rather bleak many others don't. Gunslinger girl is like DTB, many of the stories are not in themselves dark, however i find the characters quite "sad".

thanks for the reply but, all the ones you mentioned I have already watched I just did not think of them until you mentioned them.
