I'm not sure if Gantz will wipe Tae's memories of Kei, because there's always her mother, family and friends reminding her about him... Gantz will probably just erase her memories about Kei telling her about Gantz.
I'm just trying to look at things as realistically as possible, given the obviously surreal context of the manga.. I mean, I believe also that Kei has matured quite a bit; his choices in the past 10 or 20 chapters have made that abundantly clear. He is, however, also subject to teenage hormones; while he may go back to Tae now, she may have no memory of the events in Gantz whatsoever. I suppose they will still have that love for each other, but Kei didnt realize that it was possible to bring someone back until quite a while after Tae was already dead. I think a little comforting from Reika could easily have lead to a little heavy petting, and we all know where things go from there. Kei may be much more moral than he once was, but nobody's perfect.
It's been only a couple of monce after death of Katou, so it's fucking impissible for him to mature so fast ... (but he fucked so much so he becomming an asshole ) And as one dude said he was a dare devil as a kid ( so basicly he only becomming what he was before)
But he did not tell much about Gantz,only that he died and at this point having a seccond chance ... but it's still possibol that he will erase everything,that's the nature of black ball
wow, now how did this thread get dug up again..
its quite amusing to read my own rampage again, such violence in words.. *sigh*
now, people change quite fast, in a couple of months you could well turn from a complete jerk to ... well, anything better. seems like that's wat kei has done.
i would say that, if kei realise after he revives tae that she'd be endangered again if he maintains his relationship with her, he would end up breaking it. and reika is probably the easiest way to do that.
no to change yourself you need at least a year or to that point as Kurono ..No he loves her too much so breaking is off the limit
