Masaru Katou

Kato is known by the entire Gantz team for his altruism and gentleness, using force only when necessary (also known as a gentle giant according to Kishimoto). Throughout the series, he is constantly looking for another way to end the missions instead of simply killing the aliens and is always trying to find a way for all players to come back alive. Although he tries to be a pacifist, he has shown himself to be violent when necessary, an example being when Kato assaults Onidzuka without warning after the latter expressed a desire to rape him.
