Cohen of the Rebellion follows a dual-natured warrior who once lived a carefree existence filled with reckless laughter and wild songs before becoming a battle-hardened hero carving his legend across countless battlefields. Reincarnated into a new world, Cohen carries the burden of tangled destinies while fighting against the cruel constraints of fate itself. His deepest longing—to ensure the safety and happiness of his loved ones—remains perpetually unfulfilled, shadowed by broken promises and half-realized dreams. Through turbulent chaos and moments of profound beauty, Cohen forges sacred bonds with a virtuous saint and valiant warriors who stand beside him. When darkness overtakes the realm, the legendary dark king emerges with miraculous power, transforming his unyielding will into an unstoppable blade. With each strike of his master weapon, he shatters the world's chains, unleashing both salvation and devastation upon the land as the ultimate embodiment of hope and ruin.
