In an alternate universe where magic and technology coexist alongside humans and demons, the tale of Daemonium unfolds. A powerful family enlists a group of mercenaries and coerces Fulcanelli, a wizard and swindler, to summon a demon in their quest for greater power. Predictably, the plan goes awry. The wizard manages to flee, and the demon massacres the mercenaries, sparing only Razor. Razor then strikes a deal to become the ruler of the criminal underworld. The family captures Lisa, Razor’s pregnant wife, transforming her into a ruthless assassin and the spearhead of their assault against him. However, she is not the only danger Razor faces. It is only a matter of time before the demon returns to claim Razor’s soul. Fulcanelli appears to hold the key to thwarting the demon, prompting Razor to dispatch his team of alluring killer robots to locate him.
