Zoro nods, appreciating her honesty. So she can't really tell him what's in it, or what the effects could be. That solidifies his decision to skip it.

"Fair enough." He can respect her approach to this whole situation. It probably causes her less grief to just accept things and go along for the ride. It's very similar to how he imagines Luffy would react, if only his captain were here.

Alas, so far he seems alone with strangers.

As far as strangers go, Mayou doesn't seem so bad. Zoro's opinion of her promptly improves when she invites him to do something he's sure those pesky ghost hands would disapprove of. "Lead the way." He gestures, because he has absolutely no idea where to even start looking for these employee-only areas. They aren't marked, are they?

He'll follow Mayou blindly to wherever, as long as he doesn't sense that she's leading him to some sort of trap or other imminent danger. "Hey," he calls out after a moment. "What's this?" He holds his wrist up to show her the smartwatch that everyone's wearing. No such thing exists in his world, but he's observed others looking or tapping on their tiny screens, and he truly can't fathom why.
