He Should Have Ran

I very quietly and secretly indicated to Katsuki that I wanted to speak to her in private while Mary was creating the portal to send the slave girls back to the store.

"Katsuki… Don't make it look obvious but I think the Off-Worlder has transformed himself with Somatomancy to infiltrate the slave girls… There's one more person as compared to before.

Katsuki discreetly peeked over to the slave girl group before turning back to me, "I see. I shall deal with it, Mistress."

Oh~ How reliable Katsuki! As expected of my personal maid~ In that case I'll leave this to you to deal with~

I then watched her move towards Mary to supposedly inform her about it.

Well… Most of the slave girls were still unconscious anyway and only a handful of them had woken up at this point.

I recognise all of the ones who had woken up so the guy was most likely pretending to be unconscious right now.
