So... What happened to the mother ship that was supposed to crash to Earth? What happened to the rest of the aliens? Why was the Room of Truth on the alien ship if the two creatures inside were part of a race that drove off the invading aliens? Why were the aliens ok with eating sentient life forms that looked almost just like them? And raw to boot? Why did that one Gantz orb still work to transfer people home? Why didn't the war hero alien and his pals all fight at once?

I guess there's a lot of inconsistencies in the last few volumes and a lot of questions left unanswered. ( )
