The Machiavellians

Demons from the depths of hell serving loyally to the Old Nick (Satan), yet four of them turn against their own serenity. They sought to dwell unto the realm of the living as they suppose that they will have a possibility to change their selves that involves their oblivious atrocities. Unfortunately, they had trouble coping with society. They appoint another being to alleviate their situation. Nevertheless, they thought things were going smoothly but the lordship Satan of the under realm has been discerned by secretly observing them all the time. A fiendish outrage awaits them for they must pay a heavy price for turning their backs against the devil. The ruler of the unspeakable realm dispatches his top commanding officers with mischievous intentions to seize those cunning renegades. But they never knew these double-crossers were conventionally backed up by the holiness of the divine beings. Thus, war has proclaimed.
Will the force of demonic epiphany prevail? "Not exactly a demon who turns to be good, but a demon who was never evil, to begin with".
