You know, all the previous ones were about how "it's not really about gladiatorial combat/samurai duels/the bible, it's about PORN!," but this one is basically, "it's not really about the sex industry, it's about the sex industry!"

Instead of being about women sold by their families into functional slavery servicing men sexually to pay off the family's debts, it's about... women sold by their families into functional slavery servicing men sexually to pay off the family's debts by drawing porn.

... Just noticing it's not as much of a perversion of canon as normal.
