Dichotomy

A hardened con artist falls in love with another dude who was born with an inexplicable demon tail that gives him no power or extra side effects whatsoever. People are afraid of the guy and think he's the antichrist or some shit maybe. The church is mad, so they send their willingly blindfolded, mindless killers to retrieve him, but the con man isn't about to give up that demon booty quite yet.

Yup. Sure, why not.
