*Spoilers chapter 220*
I was kinda pissed with kuronos decision to leave :x but then I thought, can kurono actually leave? because now that everyone can see the gantzers, can they really leave? and would gantz want izumi to get strong people only to have them leave? anywho leave your thoughts ;-)
I say he really left... Then he's probably going to see the Gantz people... Probably die again somehow, and either
1) Get sent back to the Gantz room automatically.
2) Have someone else get 100 pts to bring him back.
Of course he'll have his memory wiped so it brings a new twist to the story... He'll be acting the same way as he did before Masaru died... That being a power hungry ass...
Of course I don't know any of this for sure... Just my thoughts...
