@ coolerimmortal: By Kei leaving the plot can progress more, rather than them continuously fighting the aliens and reiving people, this will really make a change. And They told him to leave he wasnt being an asshole. Just because the manga don't go the way you want it don't mean its shit. By it still following Kurono obviously he will have a part to play in the future. So shut up and quit whining dipshit.
@Lizard: What? He doesn't owe them anything, if it wasn't him showing them about gantz and training them, they'd all be dead. Them reviving people for him was them saying thanks. However I dunno why the hell Kurono revived Nishi instead of Titz, that was a stupid move on Oku's half.
