Four divine rulers, each governing a different region, are reborn in the modern era with supernatural abilities and the power to transform into their ancestral dragons. Initially, they live normal lives until hostile beings begin targeting them. Their task becomes stopping the "Four Sisters," a group of American women descended from the "Bulls," who seek global dominance through technological and economic control. As the conflict unfolds, the four must also navigate their roles in the modern world while evading the destructive ambitions of the "Bulls."
