The guess I have relates mainly to the fact that they're opposing the Demons - if they weren't, then they wouldn't have sent us a warning in the first place.
There's a noticeable disconnect between the occurrences of 'Rank-Up-Magic Barian's Force' and the actual demon attacks. They almost deliberately don't line up, and I think might be a separate group entirely.
Assuming there are not three distinct groups running around - the Demons, those who sent the warning, and the distributors of Rank-Up-Magic Barian's Force, I think it's safe to at least conclude that there might be a connection between who sent the message and the distributors. Which means there's a connection between your case and the Demons from Ettosyleit.
