Nishi Johichiro

Nishi has black hair, brown eyes, and fair skin; he has a somewhat cunning look. Over his outfit, he wears a loose white hoodie and baggy brown pants.

He is selfish and has a social Darwinist approach to life. He is reluctant to reveal anything about Gantz or himself, but he maintains a website where information about him is published (carefully avoiding Gantz's rule against informing outsiders, which in turn has fatal consequences).
He is cold and decisive about the facts of the Gantz game, he doesn't usually care about the other players, he is often scathing towards others in the game, and he can be hostile when threatened or angered.
He enjoys watching people die. He is also sadistic, preferring to go on missions alone, hiding and attacking whenever he has the chance, waiting until he finds the strongest monster to get more points. He is not interested in low-ranking targets.
Although he was cruel to you at first, in the end he fell in love with you
