At the end of the series will probably see some down trodden gaming enthusiast has been orchestrating the whole thing in his basement and he'll make a pretenscious comment then fade to black... the end.
My theory on why some aliens can be seen by civilians is that gantz is no longer has the energy to mask or hide aliens and gantz hunters alike. In the more recent chapters, there have been more and more aliens emerging and im guessing gantz cant keep up with that many aliens... Maybe another reason why there's a katastrophe.
Gantzers are all just experiments. Maybe just find the best warrior which they will then use later for breeding.. might explain why they even get animals.
nice i dint thought on that posibilty.... But is still inhuman, just think ppl die and you give them another oportunity o wow is great but u need to kill aliens and sometimes humans even if u dont want to but u are force to because a stupid black ball get you there.
Maybe i was thinking thinking pervertedly when i said that. Remember the dog and kishimoto? ^_^
But it makes me wonder why they even get grannies and little kids in the mix too. Obviously Gantz wants to get strong contenders (like when it asked izumi to get some) but oddly it gets pretty weak ones at the same time. Either gantz can't filter such transfers or it was programmed to be random.
My mind is kinda sketchy as to how this teleportation works, in coordination with satellites. If you remember in the very first chapter, katou and kei died in a "underground" subway. How the hell did gantz transfer them? Lasers that penetrate through thick rock?
One more thing, it seems that gantz can transfer objects and living things no matter where they are. Even if they are moving and even if they are moving in an incredible speed. Take kei, katou, the homo, and sadako for example. Then why the hell do they need gantzers for if they can transfer aliens at their will? Why sacrifice human lives to kill monsters that they can already get rid off?
The more i think, the more see that gantz is just one sick bastard, manipulating human lives. Maybe its just there to kill off humans for fun. You guys think that all of this is just a game?
