[Natori can pick up on the warning edge, and the very clear implication that Broca, at least, does consider himself to fall into that category. But here's where Natori is different from some other exorcists that Broca may have met: he doesn't go out of his way to needlessly antagonize strangers, human or otherwise. To what degree that's out of professional necessity rather than genuine kindness or tact is up for debate, but the end result is the same. If Broca wants to call himself human, Natori doesn't see the need to argue with him about it. (Natori doesn't believe him, of course, but he's not going to be rude to his face about it. That's better (?))

So: Natori gently raises his eyebrows, then gestures at their surroundings as if to encompass the entirety of the malevolent sex hotel.] The rules are different when we're in the ayakashi realm. Even a totally normal person with no special abilities to speak of can see the supernatural when in their territory. It can be a shock, but it's probably better for them that they can see what they've gotten themselves into. It'd be a pain if you couldn't see the director, right?

[He nods towards the director, who waves one of his many tentacles out of his pile of goo body. (Natori really hopes that this one isn't controversial.)]
