The ability which jailed me included a component where I could speak to my captor in a quicktopic. I declined to talk to them, because I was angry about them preventing me from creating any magical girls, but such an ability is far more to the town's benefit than to the mafia's. As well, my captor asked me a few questions, which seemed to me the kinds of questions only an innocent person would ask. Were it a trick where the captor was guilty but trying to appear innocent, I think they would have named themselves by now to reap that credibility, especially as I have been asking them to do so for awhile.
They told you who they were then? Or you just suspect it?
Frankly it makes no sense to me for a town to tell you who they are, as such an important role. Considering that you are their "suspect".
