Wrath of the Sun-Void God: A Father's Will,

Daisuke Sato was a thoroughly ordinary man—a widowed, mild-mannered archive clerk in Tokyo whose world revolved entirely around digitizing old city records and providing a quiet, stable life for his sixteen-year-old daughter, Yuna. But when a mysterious, blinding crest engulfs them on a quiet Tuesday afternoon, father and daughter are ripped from the modern world and summoned to the Holy Empire of Solaria. ​In this new world of magic and gods, Yuna is immediately hailed as "The Heavenly Savior," blessed with unmatched holy mana and groomed by the empire's pious elite to lead the crusade against monster hordes. Daisuke, possessing zero magical affinity, is relegated to the shadows of the palace, working as a low-level clerk while watching his daughter bleed on the frontlines for a kingdom that glorifies her every victory. ​What Daisuke doesn't know—and what Solaria conceals beneath its golden cathedrals—is that Yuna was never brought to save the realm. The empire secretly worships a primordial, evil deity, and Yuna's immense divine power has been cultivated for one horrifying purpose: to serve as the ultimate live sacrifice once the monster tides abate. ​When the inevitable betrayal strikes and Yuna is locked away in an anti-divine prison realm to be drained into the abyss, Daisuke’s quiet world shatters. Left for dead in the dark depths beneath the capital, an ordinary father's grief turns into an apocalyptic rage—a fury so absolute that it awakens the dormant, long-forbidden will of the pre-creation Sun-Void God. Inheriting the legendary Ten-Forbidding Domain, Daisuke ascends not to save a kingdom, but to wage a bloody, unrelenting campaign of deicide. He will tear down the Holy Empire, erase every corrupt god in existence, and burn the heavens to ash until he gets his daughter back.
