As I said on my first blog post I would create a second recommended manga thread, so here it is.
I tried to make the list of manga varied enough to appeal to at least someone other than me.
A good horror manga with vampires, the story picks up around chapter 15-16. This manga has nudity (frontal), light torture, a lot of urine, and blood in it.
Journey to the End of the World
A wonderful dark and abstract manga, I find it to be really captivating. The manga has cannibalism, frontal nudity, blood, and if I remember correctly rape.
One, if not my favorite manga, the characters, the humor, the drawing, the story all are superb, it's honestly just a great manga. It has frontal nudity, and in one panel semen.
A great shounen manga, its strength are the characters and the interactions between each other, not the storyline.. It has fanservice.
A entertaining "disaster" manga, it contains a lot of medical terminology, but you don't need to be a pathologist to understand the basics of what's going on.. It contains gore.
A nice little mystery manga, it contains the darkest harem that I have ever seen and it has good characters.. On the third chapter it shows horribly drawn breasts and this manga contains incest.
Great character design, and a epic loli, that is enough reason to read the one chapter that is released so far.. It has frontal nudity.
It looked like an average seinen manga till the end of the first chapter (the only one that is released so far), the ending has me very curious and it looks like it will be a great manga.
A manga adaption of the Nitro+ game of the same name, the story and characters are all great (counting out the main character), but the pacing of the manga is a little bit off.. JAST USA is translating all of the old Nitro+ games, including this one, but you might as well read some of this to see what the visual novel is like.. It has frontal nudity, gore, and semen.
That's all I feel like doing so far, I know, I know I didn't put down a lot of light hearted manga, but I wanted to put some of the better stuff up first (though there are a lot left).
