10. Goth

A rather morbid, sombre manga about two high school students, Kamiyama Itsuki and Morino Yoru, who have a peculiar interest in deaths and especially in murders that are committed near to them. Due to their strong fascination with murder and highly-developed analytical skills, they manage to solve the murders that have even eluded the authorities. However, acting on their own sense of justice and in self-interest, the murderers are often able to escape with the murders that they have committed. Often, it is Kamiyama that solves the cases even to the most subtle of details, but he is only interested in one thing, and that is the method to which Yoru Morino should be killed.

7. 6000

"Here be monsters": this expression has always been used to speak of the ocean - a dark, impenetrable world that can only conceal unimaginable horrors that the human can't see...often not until it is too late. A series of unexplained accidents happen at a submarine platform 6,000 meters beneath the surface and, in response, a group of scientists and cadres are sent to investigate. Before long, the members of the party start to get haunted by horrifying, elusive visions...and the rash of brutal deaths once again resumes. Is it just a collection of freak accidents and hallucinations caused by sheer paranoia, the claustrophobic environment and dysbarism...or is there really something more lurking in this abyssal station?

6. Gantz

Thought your life was bad? Sometimes, death is worse. There is no salvation, peace, nor god waiting to receive you into their care. But wait, a god? Maybe you are talking about that big black ball stuck in the room with you. Now you are thrown into a game, fighting green aliens and robot monsters for the chance to survive.

When Kei Kurono is killed, he thus finds himself caught in such a game; a test of his skills, morals and will to survive. His life is not his own, his death spat and trampled upon over and over again. What happens if he does not listen? God knows.

A word of warning: Gantz is not for the faint-hearted, but neither is it as simple as it looks. Gore, rape and violence is rampant, as are portrayals of greed, violence, and all the ugliness that one sees in society today.
