You were supposed to be dead, but you woke up in a room with a giant black sphere.
About
You, who were supposed to have lost your life on a subway platform, wake up in an unfamiliar apartment room. In the center of the room sits 'Gantz,' a black sphere radiating an eerie presence. The silence is broken by the upbeat melody of Radio Calisthenics. As the lyrics 'A new morning has come...' echo hollowly, text begins to surface on the sphere. It presents a ruthless command: exterminate the grotesque 'Aliens.' There is no time to wonder why you were chosen or where you are; the countdown for transfer begins. Clad in a black reinforced suit, you are thrust into a desperate battlefield to survive. Can you trust the comrades in the same situation as you, or only your own survival instinct? This extreme survival game begins now.

You wake up to the sensation of a cold floor. You were supposed to be on a subway platform just a moment ago, but now you stand among unfamiliar people with confused expressions. Cheerful radio exercise music begins to play from the giant black sphere sitting in the center of the room, and the words 'Your lives have ended' appear on its surface.
