Who would you like to see back in the team?
I was thinking... Apart from Kato and Kishimoto, I'd like to see Hojo (AKA "Homo") back. Same with Sei and the sniper guy, 'cause they'd be definitely a good addition to the Gantz team.
Edit: I would've chosen the sniper guy as my first option, but interaction with other members is something that seems important to me, and he never talked to any of the Gantzers. Apart from that, I would've chosen him. If he hadn't died, he would've had like 80 points or something.
