Luciel regains consciousness in a decimated parallel realm where civilization has collapsed into ash—crops wither, precipitation corrodes flesh, and perpetual dust clouds eclipse the sun. Moments from oblivion, a mutant rabbit-eared girl intervenes to save his life, triggering the awakening of an extraordinary Trainer System within him. Everything shifts irrevocably. A diminutive tortoise metamorphoses through successive stages into a celestial creature of incomprehensible scale, its shell-back spanning dimensions that dwarf mountains and rivers, becoming the foundation of Luciel's destined kingdom. A fragile seedling transforms into a colossal World Tree, its canopy repelling caustic downpours, dissipating tempests, and unveiling azure skies and pristine clouds once more. A solitary soldier ant ascends to become the progenitor of an unstoppable swarm, a biological maelstrom that devours everything in its path and leaves only desolation. The rabbit-eared girl who pulled him from death's edge finds herself inexorably bound to his extraordinary destiny. With every beast subjugated beneath his command, Luciel reconstructs the barren wasteland. From clawing through apocalyptic ruins to forging an Eden anew—this chronicles one man's odyssey alongside his supernatural beasts and an boundless system of power.
