at first Oku shows us faces, big boom, than faces again, two panels of Gantz ball, than faces again, Kei-chan, Kei-chan is alive and than that ridiculous "finished".
These last chapters were like some of the worst ever. I feel like I don't want to read Gantz in public now. It's soooo typical shonen. "Oh no, the hero is dead!". At the last moment it appears and everyone is like "Hooray, the hero is alive!"
Now I hope the next chapters are more logical like this one. The 0 point stuff (when it was clear that he probably killed something) it's something interesting.
