Holy shit fucking finally, this arc felt too dragged and I don't care about that child or his mother in the least, but at least Satsuki got some nice character development, now MOVE ON with the story, and most importantly where is my girl Chika?
This Helmet arc is absolutely ridiculous. Even more than the long period of the girls fighting over the forgettable MC's loins. At least it's almost over, from the looks of it.
Honestly what the fuck even are these worm things now. It's just so alien at this point it's the only explanation I can think of for how much they fuck shit up.
If that stupid gas canister had missed... what a crazy gamble.
Helmet might be unkillable. You can't even be sure it has a brain and that you can get rid of it with a headshot. Trying to kill it on your own sounds like a really stupid idea.
