First appearance in manga: Chapter 1
First appearance in anime: Season 1, Episode 1
Jouichirou Nishi has been trapped in the Gantz world for over a year by the time the series begins. He died falling off an apartment building roof while fleeing from police after shoplifting—a pretty pathetic way to go, honestly, and one that mirrors how Kurono starts out as a selfish survivor with a Social Darwinist worldview.
Despite being cagey about discussing Gantz or his own situation, Nishi runs a website posting information about the game. It's a risky move that technically violates the rules against telling outsiders, but he's managed to thread that needle carefully enough to avoid getting killed for it. Fans often note the weird respect Gantz shows him by calling him "Mr. Nishi"—a formal touch that contrasts sharply with how dismissively the AI treats pretty much everyone else in the game.
