Joichiro Nishi

An experienced veteran of the Gantz game, this middle-schooler arrived in the deadly cycle after a fatal fall during a police chase. Driven by a selfish, Social Darwinist mindset, he remains intensely guarded about his identity and the mission's secrets. Despite his isolation, he secretly manages a website to leak information about the hunts while carefully bypassing Gantz’s lethal rules. Interestingly, while he treats other participants with disdain, the Gantz system addresses him with a unique level of respect.
