The notes about how magical girls and their foes retcon each other after victory has gotta be a mindscrew though. If one of them does manage to kill Ieshiki, does that return every single monster she's slain, or is there an eventual time where it sticks regardless? I could see a future chapter where that happens and Yamada has to run a gauntlet of her senior's past foes to get to the one that got her and retcon her back into existence.
Of course, what truly makes this chapter is going reading the previous one again and seeing that "No worries, we'll be fine even if everything goes away."
