The series depicts both the missions and Kurono's regular life, as well as the daily lives of other Gantz players (to a lesser extent). At the end of the mission, similar to the first time Kato died, he defeats arguably the strongest alien in the series and is laid bleeding on the floor. In a desperate attempt to revive his best friend, Kato fights the one hundred point alien Nurarihyon which obliterates both Osaka and Kurono's team.


Kato becomes the center of attention in the manga and his quest to revive Kurono. As the series goes on, the rules of the missions change they can now be seen by regular people, the aliens they encounter are increasingly more powerful and dangerous, and they participate in a mission with another Gantz team from Osaka.
