You like DMC too?

trying to beat the third game

Yep. The devs even let his original name get a cameo as Dantes alias, Tony Redgrave

The gold cursive engravings say "Ebony & Ivory," but there is an engraving on the other side that says "FOR TONY REDGRAVE / BY .45 ART WARKS"

yep

Monsoon I think? From Metal Gear Rising: Revengance?
