The Exorcist ( Adam ) x The Demon

After a particularly botched extermination, Adam is forced into an uneasy ceasefire with the Hazbin Hotel. Heaven assigns him to temporarily reside at the hotel as an observer—not to be redeemed, not to help, just to ensure the demons inside pose no threat. Unfortunately for him, Y/N exists: a demon resident who survived one of Adam’s previous missions and is openly hostile, unimpressed by his authority, and eager to provoke him at every turn. From the very first day, sparks fly—not of attraction, but of rivalry—as verbal sparring, ideological clashes, and mutual disdain dominate their interactions. But when a surprise attack targets the hotel—and Y/N in particular—Adam hesitates, risking his standing in Heaven to save the demon he’s spent so long dismissing. Forced into reluctant cooperation, they uncover truths about Heaven’s corruption, challenge each other’s beliefs, and slowly realize there’s more to the other than meets the eye. What begins as hatred gradually shifts into something more dangerous, and neither of them can deny it.
