Top 5 Horror manga

So these have not been a good few weeks. To any people who actually read my blog it has been around three weeks or so since my last update, and I apologize deeply.
To cover a few of the big events that happened to me personally for the last few weeks, a loss of a loved one, a international trip,and a traditional Buddhist funeral.
Well enough about that I decided to finish off the month with a post based on my top 5 horror manga!
These are 5 of the weirdest, freakiest, scariest manga I have read in my life. The horror genre is pretty simple it contains something that is generally freaky or scary to regular society.
My top 5 are actually interchangeable because they are all pretty gruesome in my opinion.

#1 Deadman Wonderland

#2 Mouryou no Yurikago

#3 Bio-Meat: Nectar

#4 Franken Fran

#5 Pure Trance
Each of them have some kind of scary or freaky aspect to it and added along with it is the usual weirdness that comes with manga.
Dead man Wonderland: features a prison for convicts and special prisoners with powers to manipulate their blood. As you read this manga you learn of prison conspiracies and bear witness to the gruesome deaths of many prisoners and guards, I must say when it comes to death this author presents it in a sick way, we see people being hacked into pieces.
Mouryou no Yurikago: is a typical zombie situation. A high school class is trapped on a cruise ship with the rest of its passengers. The cruise ship overturns and is now upside down, normally this situation is already terrifying, but as the survivors of the first disaster try to recuperate they are attacked by what seems to be zombies.
Bio-Meat: Nectar: is a apocalyptic world when a new food source created turns on its creators and start to attack and consume humans. The main characters a group of kids try desperately to fight away these creatures and live their lives, by the third arc of this manga most of Japan is taken over by the creatures.
Franken Fran: is manga version of Dr Frankenstein, or more of a parody of the famous mad scientist. The girl has the looks of a Frankenstein and is a mad scientist. Every chapter has some kind of horrific experiment that she conducts either of her own free will or of someone requesting an odd surgery or such.
Pure Trance: now this is an odd manga. It has an odd art style that I find crazy. It reminds me of a urban graffiti style. The story itself is so odd and mind blowing weird that I can not explain it. Best way to understand it is to read it.
Well if you do decide to read these titles have a fun time and remember none of this is real....I hope....x_x
