"Hai," he says simply, straight backed with his hands laced together on the table, having finished his transition from cook-at-work while sitting. Zelas-sama would be so disappointed in him if he didn't annoy someone at least a little bit before getting down to business.
"Gaav-dono will have already noticed that a large percentage of the transplants to this place have spent their first lives as fodder for his alter, or at least been tempered by his flames. However, there are a number of them who are just as vulnerable to other influences, and Maou-dono," if his face twitches slightly as he says the title, well, he said it, what can one want, "has been pursuing those avenues. Sicknesses of the soul, the infection that an unintegrated chimeric nature can bring, lusts for corrupt power; these things are present here and he's been enhancing them. Some who would be vulnerable have their own protections, but few impregnable, of course. And some people quite simply belong to him by their natures, although," his mouth curls up at one side, "they haven't been allowed to realize this, ne.
"This is also a place where many people are not simply human, and Maou-dono has been able," that muscle in his jaw flickers again, "to set up many traps and spies in the astral plane. I've been able to arrange for the population of his spies in this plane to be greatly reduced, but not that one, as yet. If Gaav-dono will recall, I wasn't called to Zelas-sama's service until Maou-dono had already lost all of his servants, and now I'm still learning what his patterns are when he has them.
"Also, although I haven't been able to make a definite causative link, strange things happen every so often here, and some of them have had his stamp. A month of ghostly visitations, for example. Gaav-dono knows how it often is with ghosts. Either their presence is intolerable or their departure is. I don't know if he's also behind the force which prevents people from leaving here, but the fact that Gaav-dono is able to move freely does argue for that force being a power no greater than himself.
"However, I hesitate to make that link with any kind of certainty, since other factors make other suggestions. For example, I would have thought that giving minna-san a massive and collective case of cabin fever would be more in Gaav-dono or Zelas-sama's line. Also, the restrictions on travel aren't absolute even for ordinary people, and I'm not familiar with any ability of Maou-dono's to summon through time and space; summoning through space is also something that's more like Zelas-sama, although not time. But I think there must be some meaning to the fact that so many of us who've been brought here are either fighter or shinobi types."
