Under the vast universe governed by the Dragon God, this is the independent story of the Asura clan, focusing on the rise of the Asura King, Lord Kuar, who dominates the three realms. As a naturally fragile Asura youth, Yu, with the tragic loss of his family to mysterious Asura forces, finds himself forcibly taken away and subjected to hellish trials. Through countless cycles of death and rebirth, Yu undergoes a transformation, ultimately shouldering the belief of his dearest friend to become the Asura King—Kuar, renamed Lord Hou. This sparks a century-long war between the heavens and the Asuras, with the emergence of the new youth.
