Damn it, the following refers to chapter 3.5.
Nope, he never does, he found a facility that did some shit, so he destroyed it but I do understand you.
But enemies appear randomly, I love that about Nihei, he always creates terrifying and merciless situtations where death is right in front of you, he is truly a boss.
As for chapter 4:
Shit has started, heads will keep flying and that smile of the authority.
I wonder where Killy suddenly got his gun from.
