I suposse that Lady is more than enough, believe me. But, If think about it more deeper, then why not. I mean, everyone remember Enzo or Morrison? something like that kind of interactive.
I see what you're saying, but DMC4 muddies that a bit, with the Order having some very high tech equipment, even verging on Sci-Fi with stuff like Nero's engine sword. Looking back on it, it creates a weird anachronistic clash with Fortuna which looks like it's stuck in the medieval times.I also doubt the creators' emphasis on restricting DMC's technology to its "80's/90/s" sensibility with having old-fashioned tech like dial-phones, jukeboxes, revolvers and old-fashioned TV's would allow a whole lot of freedom in terms of allowing tech to play a major role in a DMC game.
The closest thing to that was the story with Ernest in the anime.I like the idea of Dante being a mercernary at some point in his life so i wouldnt mind more characters connected to that part of his life pop up.
And Enzo. The novel might not be canon anymore, but the manga still implied Dante could be hired for more than just demon extermination, as long as Enzo found it good enough.The closest thing to that was the story with Ernest in the anime.
