Rough him up a bit.

She delivered a swift kick into his stomach, causing the man to keel over onto the floor. "Huurk! Gguurh... you damn.. ARGH!" As he lay there, Shiki got on top of him, before taking his head and pushing it down into the floor. With her knife, she held it against his neck, threatening to cut open his arteries if he didn't speak. "You seem like the kind of guy who holds a lot of secrets. Or at the very least, knows them. You should spill them out if you value your life. If not, I can always start slowly, beginning with your dick. You seem to cherish it a lot judging from how eager you were to get it on.."

"O-Okay! You don't have to do that, lady! Me and my crew... we've been going around scouting out girls we think that'd fetch a nice price on the market. After testing them in a hotel, we'd take them back to the Warehouse by the dock for more training, and then eventually ship them out to the States. I don't know how many people work in this scheme, but I've seen plenty of guys. Now, I swear, that's the truth. I really don't know anything more after that!"

"Is that so?"

"Yes! Yes please!"

Well, that was a decent amount of information. She can work with that. As for the guy... he can figure out what to do with himself.
