That's where you're wrong, kiddo.

I hope there's a sequel where you go to heaven and try to get a bunch of angel girls in a harem.

Or the Angels come to earth to confiscate the Demon harem, then Helltaker has to rescue them in heaven while winning over Angels as well.

I can imagine a sequel would start where the game ended and reveal that the cops are actually angels disguised.
