You know, I've wondered if Demons could use Lacrima to counter the 'No Magic' rule. It doesn't even have to be implanted, I'm sure a Demon could store some weapons in Lacrima and release them as if he was using Requip.
I'm also not trying to bypass any rules, I just want to give my Demon guns.
Because Guns are rad.
The moment I posted that comment I found out how to do it...
...look, problem solving was never my strong suit...
