Personally, I hope that Kurono Kei comes back as an "Alien" or vampire. If Gantz is like a little kid playing with human lives like ants, and forcing them to kill another race or species, wouldn't it be reasonable that there's another "kid" who's playing the "aliens". And then ppl who die would stand to have as much chance to be revived as a Hunter or Alien/Vampire.
I'm wondering why aren't there ppl speculating whether Kurono Akira would come back or not. He could prolly bring light to the plot on Gantz or the vampires, considering he's the main protagonist's bro.
That's in intersting idea, rexyke. Though I think with Host Samurai and Chigusa (or whatever her name is) the vampire quota is filled. Akira would be an interesting addition especially since there's probably some bad blood between him and Host Samurai. That's assuming he isn't dead.
