Does the MC of that series actually come across as a nasty irrational goblin hater? I've never watched it, because I don't care much for pessimistic worlds; but I heard there's an episode where he justifies he's sure you'd find good goblins somewhere if you looked, yet those just don't draw his attention by terrorizing humans and whatnot. That seems like the cleverest handling of "always chaotic evil" I ever saw.
I know this has nothing to go with where this is obviously going, but I got curious why someone would draw not-goblin-slayer smut, and also curious what and how that'd retain from this series I do not know. Godspeed, Goblin Hater, and remember the safeword.
