There is a whole thing at 4chan right now where a guy is summarizing the events of the new novel. The thing is I don't think they'd appreciate me posting the transcript here so I'll just wait till
DMC5info releases
their summary and post it then. In the meantime I said I'd talk about the events of the anime drama CD.
So, here's the deal. The drama CD starts out with Dante getting payed a huge amount for a job he pulled but he is giving it away to a person he knows and they make a huge mystery of it. It's someone who's known him longer than the main cast, even longer than Lady. Well, it's Enzo. Enzo was Dante's old info broker but in a long flash back it is revealed that not long after DMC1 Dante and Trish took a job to track down a devil gun created by a famous demon gunsmith calle Machiavelli. If I remember right, a Spanish Youtuber named Kalina Ann translated some of the opening and said that Trish said that if Sparda was demon swordsman of legend Machiavelli was the demon gunman of legend.
Anyway, on the job Enzo tags along and when he grabs the demon gun his hand becomes fused with it and in order to save his life Dante chops his hand off. Enzo quits his work as an info broker, Morrison takes over his duties and Dante sells his left over devil arms to Enzo to sell for a profit (which, for the record makes no sense to me. Neither job is exclusively a two handed position and considering he lost his hand to a demon weapon you'd think being surrounded by them and being in the same same job that cost him the hand aren't that much of a difference and one isn't much of an improvement from the other).
Trish decides to go all over the world to rid it of the Machiavelli guns and asks Dante to change the name of the shop back to Devil May Cry because Devils Never Cry what their shop and now that she's leaving it's only him. Flash forward and Enzo can't sell the DAs and then a demon appears, possess Lady and Dante has to use Alistor to beat it. A&R make a cameo but aren't used, in fact, Dante sold them to Enzo, along with Alistor. Lady kills the demon after it gets away and Dante gives the weapons back to Enzo to sell and all goes back to the same old.
