There, the sphere gives them special suits and weapons, and sends them out on a mission to kill aliens here on Earth. While these missions take place, the rest of the world is largely oblivious to them. These missions are lethal - few participants survive them. The sphere calls the shots, and it's not the slightest bit nice. Its name... Gantz.Gantz:O featuring Yuki Kaji and Daisuke Ono is streaming with subscription on Netflix.
