Well, that's a bummer. I might be interested in GMing. I'm somewhat okay at taking over for other peoples' ideas. Still, I'd be happy if someone else stepped up.
EDIT: why don't we just scrap God of War and use Darksiders instead? Its lore fits the primarily angels-versus-demons theme of Bayonetta and DMC quite well. If you wanted to do the DMC parts, I could do one or even both Bayonetta and Darksiders.
There is like a strange purity about true Devil Arms. I would say humans would rarely have access to the level of power to make full-fledged ones.
Maybe pseudo-Devil Arms? I would say Devil Arms wouldn't be made for public use or anything, perhaps your company manufactures weapons to the human realm, and they have a 'special' line for demon hunters and special forces, which are the pseudo-Devil Arms.
I'd say that the greater distinction to be drawn would be between different strengths of devil arms. I would not say that it's an impossible power to make fully-fledged ones, just a difficult and specialized technique refined over the generations. The company's employees might not be the world-tier fighters that can go out and acquire devil souls themselves, but if a hero or villain brings one in, they can definitely make a powerful weapon out of it. Basically, the company would sell weaker ones outright, but stronger ones can be made (for a price discount, no less) if a warrior gets a soul themselves.
@Sho Minazuki This is true. I recall that true Devil Arms are actually forged from the soul of a devil in question, or otherwise served as the devil's signature weapon in question.
But I also know that normal guns just don't cut it for high-power devil hunters like Umbra Witches, who would infuse their power into their weapons- even Dante's own guns were specially made to withstand the wear-and-tear he put them through. An arms manufacturer would probably make a good profit in the devil hunting business, therefore, if they issued such special-issue weapons to those interested parties.
That's it exactly. They might not be the most powerful of Devil Arms, but they're real weapons crafted from the souls of real devils. The company primarily catered to supernatural warriors, be they hunting devils or angels, but has expanded in more recent years to sell watered-down versions to the public of their devil arms with technological replacements for the magical abilities of the weapons, and obviously no souls, though a nice touch would be that they run on ammo batteries that contain magical power, meaning that normal customers have to keep coming to the company to resupply ammunition.
