Some Sakata action:
He was brave too, great character.
Oh yeah...he was TOTALLY a badass!
Unfortunately....I really don't think he'll come back to life....even if they had 100 points to spend; they'd spend about 3 pages thinking about it....but they'd remember what he said at the start of the Nuri mission and not bring him back. His part in the story is over, I dare say...I'm not happy about it, but that's just the way Oku roll's, I guess.
Well. That's the way of life. (rather way of Gantz)
His part in the story is over. Same like Izumi, unfortunately
Sakata wasn't cold when he told Katou not to revive. He was
being honest and he was right, Gantz is a horrible cycle. Someone
dies and someone takes their place. It does cheapen your existence
to you can be wished back to life, like it was nothing. I don't blame
Sakata for not wanting to be braught back to life. Sakata was a real
man for saying that. That's why he is my favorite character.
Sakata truly was a bad-ass... He even kinda looks like a super hero with his shades.
I forgot about that? perhaps Sakata was once inside a Gantz ball lol.
Whoa I forgot Sakata said that, I smell new theories brewing up.
Maybe, he was in a gantz room once, but he can not remember the missions because he was in a diffrent gantz room at the time.
He cleared the game 7 times Maybe there is something behind this...
Maybe his psychic powers where a 100 point reward....
holy crap maybe it was! but then it would be impossible for sakurai to have powers, but I think it's highly possible that he was in the Gantz room before, maybe that's why gantz calls him dumbass, cause he doesn't remember that he was there.
There could be many possibilities for him to recognize the black ball in some way...
As teh100pointer and digitaldude noted, he could have been in the Gantz room once. It would seem logical, that he chose freedom when he got 100 points (I don't think he would've chosen a better weapon because of his psychic abilities or reviving someone).
What came also up to my mind is that maybe he saw the transport of the Gantz ball, since they somehow have to be managed to get from Germany to Tokyo... maybe experimenting with his abilities, he might have seen the Tokyo ball in a transporter, but since it was just a big ball (if that isn't strange enough ), he didn't care much about it...
Or maybe he saw some user-avatar of a Gantz ball while he was surfing in some forums - you never know until Oku reveals more details about it
