There are two worlds so different, they are never supposed to collide. Heaven and Hell. Frank Iero is a demon looking to climb the ranks of Hell to get closer and closer to being king. However, he is unfavored by the king and has already been pegged as a troublemaker, even in the darkness of the underworld. What lengths will he go to to get what he wants? Gerard Way is an angel sent to earth after he violated the ancient, unspoken law of Heaven: never show yourself to a human unless it is imperative to do so. His job is to find and destroy troublemaking demons, but how can he when he is so unsure of even how to go about living on earth? And when he meets his natural enemy, can he bring himself to end the eternal fight once and for all? In a tale about unlikely love, and differences so extreme that they may never mesh, we find ourselves exploring a somehow unbreakable bond. But how can it possibly survive?
