Anti Hero From Hell

Jack Storm was supposed to die a nobody. A violent delinquent with no future, Jack’s life ended when he threw himself in front of a speeding car to save a child. It was the first good thing he had ever done—and it cost him everything. Hell noticed. Rather than damn him, a cosmic infernal contract granted Jack a second life: he would become Hell’s executioner, sent back to Earth with demonic powers to eradicate rogue demons and possessed humans. If he completed his task, he would be allowed to live again as a normal man. But Hell never gives gifts. Jack’s powers grow with every demon he kills. He gains abilities beyond any human—teleportation, nightmare control, summoning armies of demons, regeneration, reality-warping force. As he climbs the demonic ranking system—from D-rank all the way toward godlike S-rank—he becomes Earth’s strongest defender… and its greatest threat.
