Think your life is bad? Sometimes death can be even worse. There is no salvation, peace, or god waiting to take you in. Instead, a big black ball, Gantz, appears and throws you into a deadly game where you must fight green aliens and robotic monsters for a chance to survive. When Kei Kurono is killed, he finds himself caught in this game, a test of his skills, morals, and will to live. His life is no longer his own; his death is spat upon and trampled over repeatedly. What happens if he fails to listen? The answer is grim. Gantz is not for the faint of heart, and its surface simplicity belies its complexity. Gore, rape, and violence run rampant.
