When a boy watches the Devil King tear his father from the world, vengeance becomes his only purpose. Bound to a blade bathed in the blood of ancient devils, he joins a ruthless cousin and an unexpected ally—the Devil King’s own forsaken son. Together, they carve a path through the ranks of hellspawn, facing horrors that twist the line between man and monster. But as they draw closer to the throne of darkness, the weight of blood, betrayal, and sacrifice threatens to shatter more than just their bodies. Not all who begin the journey will live to see its end.
Wandering the wilderness with nothing but vengeance in his heart, Mortis begins his search for the devils who tore his world apart. But the silence of the woods is shattered when he is ambushed by Protos—one of the last 5 remaining devils—and his horde of demons. Overwhelmed and on the brink of death, Mortis is saved by a final gift: the awakened strength of the demon slayers, granted by his father’s spirit from beyond the grave. With his newfound power, he crushes the demon army—but Protos proves far beyond his reach. Broken and bloodied, Mortis is left alive… as a warning.
