Character from Gantz.
A veteran of the Gantz world, having arrived there over a year before the beginning of the series.
He comes off as a Social Darwinist, and though he has been in the Gantz game for quite a while, he doesn't bother giving out much information to his teammates (dubbed Tokyo Team); about the purpose of Gantz, the missions and the Aliens.
