Well... i've read A LOOOTT of manga...so i'm gonna write the ones i remember the most.
Akumetsu -
This manga...was awesome...if you'r into politics and mysteries and shit that gets you like "WTF, HOW HOW ? HOW THE FUCK DID THAT...HOOOW??????..." and like lots of blood...and violence...it also teaches you a lot about japans economy...though
i don't think that's real...but lets look at Greece... now this guy Akumetsu.,...in the manga...stopped japans economy from going towards the same situation Greece was and probably still is in....Wolf Guy - one of my favorite Mangas, and it's still on going... the artists and author who did Akumetsu are doing this one, so this is an immediate fav from me
... Basically, it's about this guy... who gets beaten up everyday... buut its not your regular story(Guy beaten up -> gains powers -> is awesome)... its more like... he can take it... they beat him..run him over with a car... carve "mutt" into his back...torture him...but he just rises up like its nothing...and smiles
...
badass ... his wounds heal in a matter of minutes however big they are...oh and did i say that he turns into a werewolf at night and jumps around buildings at night... This so reminds me of batman XD...
Bleach - i think you'r all familiar with this...
Naruto - do i need to say?...
One Piece - if you don't know this one...well... sad for you XD...
Sun - ken rock - ahhh this ones awesome..its about this guy becoming a boss of a small mafia gang...then taking over a whole city...and then expanding and just expanding...really good manwha ^^
Beelzebub - now this guy...i feel sorry for... he became a baby's parent because he is evil and despicable XD... he is the definition of Evil!... and the baby, Beelzebub loves it... why ?...well it might have something to do with Beelzebub being Satans baby...lol..
Dengeki Daisy - This is about a hacker who has to pay for his sins... or something...its really good, i like it
... if you'r into romance and sometimes violence... and a lot of comedy
... then this is something for you
... i actually don't wanna spoil anything, so i'm not gonna write much about it...
The Breaker - AWESOME AWESOME AWESOME <3 <3 <3 <3 <3 <3.... LOOOVE ITTT!!!!...Fighting manga...
"Weak guy gets beaten up -> finds teach -> trains him -> he becomes badass..."
The Breaker: New Waves - still on-going... awesome manga
...its the second season from the first one...
Veritas - A-W-E-S-O-M-E!!!!!!!!..... also a fighting manwha... main guy is strong...but not 1vs 10 ppl strong
...finds a random dude
who is like 1vs10 ppl strong...and forces him into making main guy his disciple
...
Ao No Exorcist - Nice manga
...i like it...
Transfer Student Storm Bringer - NICE NICE NICE... this is just.... this manwha is unique...check it out...i know the art style might seem a bit...uh unusual... but once you get into the manwha, you'r gonna be hooked
...
Noblesse - Nice Manwha, i'm lucky i found it so early... there are 202 chaps now, i started reading this when there were 50 chaps...and i've read every chap... it's almost like uh... Bleach or Naruto for me... i'm waiting for it every week checking my mail...
Tough - This is a uh...well ..uh... it's a fighting manga... but mm... it's very unique...it has things like Clans...who have special techniques....and its...its hard to put into words, but know this, since i'm only mentioning the ones that i can think off right now, it means this is a very good manga!!!..and you'r not going to regret reading this, trust me!
Hajime no ippo - You've all heard about this one right ?... Boxing manga...its really good, very realistic... it might have some like "magic moments" but those are because, they push their bodies to their limits...and tell me you guys have never done that ? running outside and you feel the pain in your chest, and legs but you'r like "FUCK THIS, I AIN'T STOPPIN *starts to run even faster...* "
cuz thats what this manga is all about...pushing yourself beyond your limits.
Hitman reborn- shame on you if you don't know this one...
Soul eater - also something you should be ashamed of if you don't know this one...
Holyland - Very uniqie fighting manga... its about fighting on the streets where everything goes, and where its "do or die"...
Deadman Wonderland - Main guy gets put in Jail because he "supposedly killed all his classmates"...but is it really what happened?...
Didn't someone else maybe do it?....maybe...red...man?...
Hellsing - A LOOT OF BLOOD, A LOOOOTTTT OF BLOOOODDD:... hated the anime... loved the OVA...loved the Manga...
Drifters - It's from the same guys who made Hellsing.....very nice art style... me like :3
And those are the ones i came to think of right now
..hope someone will get into at least one of these
....
