I am looking for mangas with murder or death in them, but not tragic ones. from extream like battle royale to just a little bit of blood. But something with blood or violence, thanks ^.^

edit: by not tragic i mean emotionally tragic, like a girl who's in love and her boyfriend is killed/dies kind.

Hmm, you can try Detective Conan. I don't really know if it is what you are looking for. Also Fist of the North Star i guess.

I'm not quite sure what you mean either, but currently I'm reading Bio meat which is something like a horror-survival manga. I'd say if you enjoy zombie movies, you'd enjoy this.

I second Detective Conan, that manga can be a lot of fun. Akumetsu is a manga about a superhero who violently kills white-collar criminals. And maybe even Deadman Wonderland which is about a super jail.

I'll try to think of some more later. I know the authors of Akumetsu are currently making a werewolf manga that looks interesting too. (Edit: It's called Wolf Guy - Ookami no Monshou)

Shigurui (I think you should read this first judging from your taste XD)

Edit: Add Shinsengumi Imon Peace Maker - death and murder play a major part and not all cases are sad, I think.

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

From a bumper sticker I like:

Cynthia the Mission
Blade of the Immortal
Vagabond
Parasyte
Gantz
Shamo
Shut Hell

Are you looking for gore/horror? Because if you are, there a lot of seinen that is like it... I just listed these off the top of my head... Battle Royale is pretty tragic, though.

Edit: Berserk is a classic, and I almost feel redundant for adding it.

One Piece, thousands must have died in what we see already.

hellsing and gantz are awesome, I will look at the other links soon, I love gore... and i updated my first post. >.> from what I have seen of One piece NO ONE has "died"...they like just show up later....

Cage of Eden might work
i also second Gantz

When your love life goes nowhere, where do you escape to?

How about Kurosagi Shitai Takuhaibin (or Kurosagi Corpse Delivery Service)?

It's actually one of my all-time favourite mangas. Does it deal with death. Why yes. Quite literally in fact. Your body (though a single organ will do, if there are no other options available) is their business.
Never has morbidity been so fun!

Lots of (Blood + Violence + Deaths) = Koroshiya Ichi
You might want to look at Basilisk as well. It is kind of tragic, but it would be heavily outweighed by the violence/action portion of it.

Eden is somewhat like Gantz, as in there are no restrictions to who lives and who dies (i.e., if a character can die, chances are they will).

I second Vagabond and Blade of the Immortal.

X/1999
Death Note - for the most part but not a lot of action
Diabolo
Number
Nabari no ou
Pet shop of horrors - but a couple of deaths are tragic
Kuroshitsuji
Aflame Inferno
Break Blade
Dogs
Zero
Full metal Panic
Akusaga

Most of these are fairly light action manga which happen to involve death, a couple a little darker but for the most part they aren't tragic.I second/third Gantz, Basilisk and Blade of the Immortal as well.

The pen is mightier than the sword...and considerably easier to write with.
