Since you have a Lupin the 3rd picture, try reading that. Bleach is pretty good. Uh...Case Closed. If you are into ADULT THEMED meaning >.< sex, then there is some manga like that. Go for Ai Yori Aoshi. It's...not really sex themed, but it has its moments. King of Hell is pretty cool. I like Nightmare Inspector too. Then there is some Vampire stuff you might like. Vampire Hunter D and things like that. Also, if you like Bleach, then check that out too. I hope my little list of stuff helps. :D "You can only be young once, but you can be immature forever! "

When I say ADULT THEMED I am NOT referring to sex.  I just don't want to read something geared to kids.

you might want to gave ninija girls a look and vampire-knight and try gun as well i know of a few more but wen i rember them i will wright them down and put them in here for you .

Night Head Genisis is and  is actually rated for 16 yrs and up so not geared for kids.  I like D. gray-man too, and tokko is not for kids."Long is the way, and hard that out of hell leads to light."

you might give gundam a try as well.

Disturbing, violent, adult themed manga.... Thats gotta be Gantz. People exploding, being eaten, hit by trains. Pretty brutal

 you might want to try out vampire knight as well it is very very cool and the story is well done.

but i would go with bleach and naruto and one pieceand ect. but thats just me lol

black cat is also a good one to try out as well

Depends what you like I guess, Bleach is awesome, Hellsing is good if you like vamps (this one is nice and violent lots of blood and general violence) so is Vampire Knight (not so violent but good story) and Trinity Blood is good (action, violence etc), Death Note is nothing short of amazing READ THEM (but it is more plot and such over action) lol. Um S.cry.ed was good  violent and at times very active, but really good, I was kinda sad it ended so soon. xXxholic seems good but i've only read the first one so far so, (and no the xXx does not stand for sex) Crimson Hero was good too if your into volley ball or sports with a little romance involved. Anyway good luck, have fun!  I must admit though that most manga I've run into may have all ages appropriate stuff in it I don't think you'll end up finding much that is "childish" I mean most anime and manga is aimed at teens and up so. omg so long Sorry lol!!Love... is just a different kind of pain.

Beserk, Black Lagoon, Monster, MPD Psycho, Hellsing.

I'd try Descendants of Darkness. It's got humor and action and other great things.

elfen lied and neon genesis evangelion are also psychologically oriented and include some graphic scenes.

I have only seen it mentioned once on this form, but Berserk is the most violent adult-themed manga that I have seen as of yet.

Try Monster. Descendants of Darkness is good too. By the way does anyone know where Descendants of Darkness manga can be read online?

Ok

you should check out decendents of darkness death note you should definatly check out super good shows (:
