As Hellgates open across the globe, humanity falls, bringing with it the death of Goong Nam’s family. On the edge of a cliff, he loses hold of his beloved daughter’s hand as she falls straight into the jaws of a fiend. He wishes to reach out one more time with his shattered arm and grab her hand. He wishes to turn back time. These wishes can be granted, but for a price: completing a legendary quest by offering the heads of 666,666 high-ranking demons. Thus begins Goong’s unrelenting, blood-soaked battle, filled with chaos and an unyielding love for his family.
