This is getting interesting, but it is not where I expected Gantz to go at all, compared to the beginning of the novel. Having two Kurono's is a bit confusing for his character. It would be extremely terrifying to have aliens descend and then sweep up everyone in cages - very suspicious when you could just kill everyone outright.
Have all the hunters gotten enough "practice" when it comes down to this battle? One question that has never been answered is why the aliens in the beginning where not visible, and now these are. Did the Gantz balls have anything to do with that?
