From the introduction:
Welcome to the world of Monster Girl Quest. The world is dominated by two factions both run by physical gods. On one side are the Mamano, lead by Alice, they are a collection of all female races that thrive off of sexual and non-sexual predation, though they can live comfortably in some human cities without issue. On the other side are the Angels, lead by Ilias, Ilias created humans and angels, but hates monsters for their predatory nature and obscene activities, ironically, despite this, the primary punishment for sinners is rape. The world is filled with gray but one hero seeks to save the world and promote coexistence between all! If he doesn’t get raped along the way.
