I've seen way too many of the "ancient worlds turning out to be post-apocalyptic worlds" genre now. Like c'mon why not have it just be something else not birthed from human tech??
I haven't read the manga in a while and it took me until after the dunk for me to remember that they're supposed to just be in a really good crossdressing outfit
Wait wait... so was this actually updated or is this a chapter that existed for well over 3 years? Didn't the author/artist have an issue where they couldn't draw which leads to the hiatus?
