I was quite curious to know what exactly a false minoshiro is.
For me, they seem to be some kind of bio-technology "machine" or cyborg or something of that sort, that has the capability of storing a lot of information. The reason I think they are not "naturally" occurring is because of the way they talk, which seems to be similar to machine speech. However, they also seem to be similar to living beings, because the false minoshiro was able to surpass the program denying access to its data in order to be spared by Saki and her friend. Basically, what exactly are they, and where did they come from? Is that ever explained in the anime or the novel?
