I believe it's just human. I've got about 20 hours into the game over the course of the last few days (probably less time actually played, that's the time on my savegame and I think RPGM operates on a faster time scale or something, lol) and I haven't seen a single scene with monsters, no defeat scenes either. I'm basically at the very end of the game now, just have a few things left to do but I've already paid off all of the debt levels and every single H-scene so far has been with humans.
When choosing your difficulty in-game, it says something about selecting the Hard mode difficulty so that it's easier to get defeat scenes without having to force yourself to lose, but I'm not sure why the OG translator said this because as far as I can tell there are zero defeat or monster scenes--in fact, every combat defeat results in a game over and a kick back to the main menu. I don't think dazedanon's TL tool inserted that difficulty description text, it should probably be removed.
Unrelatedly, but similarly, there are a few text insertions that should probably be removed. I should have commented about them here when I first encountered them, but neglected to and now I'll have to go back and search for them. The OG translator added a few bits of personal text to mark his progress with the translation. Specifically I can think of two scenes that have text inserted by the translator after the scenes end, I forget the context of the first one, but the second one I saw was him basically saying "This is probably the last scene I'll be able to translate for a while, for XYZ reasons," which is a fairly standard thing you see in incomplete games or translations.
I assume these bits of text just got missed when the TL was finalized, and I assume the same is true for the difficulty description at the beginning of the game. That difficulty description doesn't really make sense in my opinion since there are no defeat scenes and losing in combat always results in a game over.
