I can appreciate a story having a proper ending instead of being endlessly milked or whatever. MC had his arc, we got our zorn, manga done.
Oh no, they're doing the same mistake we did... drilling oil and automobile mass production...
It's funny that the ending is basically "Finally respecting men, they instantly started making cars and drilling for oil. Soon turning the cutesy albeit twisted fantasy setting into something resembling contemporary history". Still 100x better than "The end, they lived happily ever after" though. And its cool that every character got their own development in the post manslave world. Hoo boy, the things this manga makes me type.
