Angels and Demons have a natural hate for each other a sort of rivalry so to say. A demon sees an angel as a higher up, and rightfully so because an angel could kill a demon with the flick of there wrist. So when (y/n) makes her first annual trip down to Hell for the extermination there was some trouble to be expected. (All Hazbin Hotel/ Helluva Boss characters belong to Vivienne Medrano/ Vivzie Pop)
