@Foxtrot94: Perhaps Nephilims are the only ones powerful enough to go toe-to-toe with the Demon King, after the Hellgate is shut down and he's made "killable" again.
@TWOxACROSS: Now that Limbo has slipped into the "real World", and with Mundus's defeat also, what might become of Sparda? I thought in DmC he was held captive in Hell or something.
So THAT is what is really required to kill him. Shutting down the Hell Gate. Not being Nephilim.
Or maybe you have to destroy the Gate, but still be a Nephilim to defeat him...?
*still waiting for new chapter*
So it became a self-fulfilling prophecy.
I think we all forgot one of the most important elements, humans. Will they accept Dante into their society or will they shun him. Dante only looks human after all. How will Kat be treated for her association with him. How will they fight against the demons, technology magic or something else. How will life in the human realm change due to the war with demons.
And what about the demons themselves? How will they react to Mundus' death, civil war? Who will be their new king, will they submit to Vergil like the demons in Vergil's Downfall. Will more friendly demons like Phineas turn up now that the tyrant is gone.
