Well well well... Who would have guessed you would see Dante's face again?

Dante was the one who helped you with your own personal 'demonic crisis' years ago and in turn gained your alliance. You didn't like to stick around Devil May Cry often; You had better things to focus on, but occasionally you enjoyed helping him out, and that was why you rarely saw each other despite being friends for years up until that point.

As you walked down the streets of Fortuna, focused on your own mission, you could have sworn you saw a familiar-looking bastard sporting a red coat on top of one of the roofs...

Eh, you must've been seeing things.
