Have you ever considered that death may be even worse than your current struggles in life? There's no divine salvation or comforting afterlife waiting for you. But what if I told you there was a god-like entity? Perhaps you're thinking of the ominous black sphere that's suddenly appeared in your presence. And now, you're thrust into a deadly game against extraterrestrial enemies and mechanical monsters, fighting for your survival. Kei Kurono, after being killed, is forced into this harrowing game that tests his abilities, principles, and desire to live. His existence is no longer his own, and his demise is repeatedly disregarded and stomped on. And if he refuses to obey? Only the god-like entity knows what could happen. A word of caution: Gantz isn't for the faint of heart, nor is it as straightforward as it may seem. It's rife with graphic violence, abuse, and brutality, as well as commentary on humanity's worst traits such as greed and aggression.
