1)Whose to say the ones left behind are the originals.Originally Posted by Kagetenshi
2)I think Gantz gave Izumi the little gantz ball and that gave him his memory back.
3)Perhaps mangaka left that gap but perphaps half way through he may have regretted making her or just felt like royally screwing her over. Maybe thtas too harsh its just this character wasnt....man whats a good way to put this.....not all there? She really didn't have much emoyion in the story, or rather it was overshadowed by the gantzers. Even when she was being hunted all of the focus was Kurono. When she was killed no one felt sad for her but felt bad for Kurono that his efforts were all for not. Bah well this is just my one-sided rambling. There are plenty of people here that like her. I suppose at ther very least the mangaka could have done more with her. Sorry if I offened the Tae fan.
All six of you.
