[Kakyoin listened in silence, thinking carefully before forming a response. If Kyuubey didn't want Witches in Nyoi-cho, and Yamashita was working to create them, then-... Something occurred to him, and he flipped through his notebook again.]

'January- A batch of magi has appeared in town all of a sudden. Is Kyuubey hoping to reclaim this place?'

I think...I overestimated what Yamashita is responsible for here. The city's barrier and the Nightmares...those aren't her or anyone she's working with. If this theory holds and what you're saying is right, then all of that has been Kyuubey from the beginning.

The way magi and Soul Gems work within this barrier is completely different from the rules of the world outside of town, we know this for a fact. Witches don't--shouldn't form within its range, and barring the interference from that fake Witch's flood, I'm sure the Doll's never would have manifested at all.

We had already theorized this city was an experiment for some unknown purpose, but it's not Yamashita's. It's Kyuubey's.
