Hrmm... If I had to choose a song for Vincent, given my rather eclectic (read: super weird) taste in music, [url=https://www.youtube.com/watch?v=R9NvyvKvbmQ]The Black Case[/url] would seem like a good pick. [url=https://www.youtube.com/watch?v=572CtMeYsFY]God and the Devil[/url] seems like it might fit, too, if only because the singer has that sort of "I'm hot shit and I know it" vibe to them. In addition, given these lines from your post at the top of page 5:

[quote]Then he began to form an idea in his head. Kill all the Grit. They were the enemy after all. He had the power of magic and technology on his side. With the two of them together the possibilities were infinite.[/quote]

[quote]He glanced over at the roughed up group of people. He had to make sure they lived.[/quote]

[url=https://www.youtube.com/watch?v=CJxUJMB_HYg]Holy Knight[/url] or [url=https://www.youtube.com/watch?v=OBwS66EBUcY]Holding Out For a Hero[/url] may also be good fits.

Hopefully one of these fits Vincent well enough to be added to the playlist! =)
