Nishi is my favorite character in this series so I'm happy that he's back and he seems to have a better personality now. But the whole thing about Kei forgetting his girlfriend and him laughing at all the dead people on tv makes me hate him. I went from Loving him in these last 9 ish volumes to now hating him. But I'm also excited to see how this story ends now that Kei is gone.
@Oldays I mean that's how he was at the beginning of the series so it does make sense that he has just returned to his old self now that he has forgotten everything he has been through
I guess Gantz can't revive Tae with her memories intact since she have seen too much, and their relationship only picks up after the shorty alien showed up. Considering how Izumi could vaguely remember some things, there may be hope.
