Bologue Lazarus introduces himself as a debtor bearing a peculiar curse. His wounds close at an unnaturally accelerated pace—blood retreating, flesh knitting together as if time itself rewinds. Before a terrified dying demon, he whispers the truth: this grotesque regeneration is his "blessing," payment for the "debt" he owes. Sixty-six years have passed since the Scorched Earth Fury's devastation, when Opus of Oath City emerged from the Holy City's ashes. Now, two continental superpowers—the Kagader Empire and Rhine Alliance—prepare for another cataclysmic conflict. Hidden organizations surface from history's shadows: the Order Bureau, King's Secret Sword, Order of Truth, Corrupted Sect, and All Secrets Order, each seeking a place in this impending chaos. Behind the scenes, devils revel in mortal suffering, consuming offered sacrifices while weaving through fate itself. They distribute curses and blessings with cruel precision, watching as former kindred spirits descend into mutual slaughter and hatred.
