So the 'twist' is that this isn't isekai at all, suckers! Don't we feel silly? The world building here is problematic at best: Essentially Gate happened, the demons were winning, and caused human society to crumble, meaning we invented/discovered magic? Huh? Then we made super 'living weapons' (also known as teenage angst accumulators) to finally destroy the invaders and just left them to their own devices? Huh? And the world just kept spinning for millennia since, reverting humanity to the actual fantasy middle ages even though there are literal robots buried under their feet?

I will never call this smart, but I'm still enjoying it as the characters are fun interacting, the problem solving is fresh (not just blindly requiring the hero's wisdom), and the pace isn't too slow. The goblin/imp character from the flashback might be the most fleshed out character in the series thus far, though his influence and message is the tried and true cliché of 'live for yourself', I still enjoyed his episode as their conversation was just half him stalling for time to not get killed, at first.
