Description:

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. (Source: MAL Rewrite)

Killy is a man of few words. He wanders, seemingly endlessly, through a lonely, gargantuan labyrinth of concrete and steel, fighting off cyborgs and other futuristic nightmares, searching only for something called Net Terminal Genes. And he has a very powerful gun, which he uses without hesitation whenever anything resembling danger rears its ugly head. Who is this quiet, violent, determined man and what are these Genes he seeks? The small communities he finds tucked into the crevices of this towering, dystopic ruin hardly give him leads on his treasure, driving him to find larger enclaves of civilization where people can reveal more about the world he lives in and the quarry he seeks.
