When a legendary assassin discovers he carries dragon blood, everything changes. The Exorcist Clans' collapse doomed Earth itself—only a handful managed to escape to another realm, including him. Yet his greatest betrayer struck first, ending his life in that foreign world. Death wasn't his fate. Instead, he awakens as a newborn in the past. "I'm reliving my beginning." Earth remains intact, and the Exorcist Clans remain ignorant of the catastrophe awaiting them. Wielding awakened dragon blood, mastering the apex assassin Class, and guided by a Fallen Angel bound to him through the System, he has but one obsession. The world's salvation holds no interest for him. His hunger burns far deeper. He will pursue every enemy who razed his former world. He will find every blade that pierced his heart. Vengeance is all that matters now.
