The divine council's verdict of extinction stands, but the valkyrie Brunhilde has forced a final chance: the Ragnarok, a tournament of thirteen one-on-one death matches between the gods and humanity's greatest warriors. Record of Ragnarok IV continues this high-stakes contest with the tournament already deep into its decisive rounds. The fourth season focuses on the tenth and eleventh battles, two confrontations that could tip the fragile balance of the score. One duel is a pure, intense clash of swordsmen, a test of speed, precision, and martial skill between a legendary human blade and a divine opponent. The other is a battle of strategy and cunning, a psychological and tactical game where raw power takes a back seat to deception, environment, and intelligence. As the arena becomes a stage for both honorable combat and ruthless calculation, the weight of each loss grows heavier. Brunhilde's true designs for the tournament remain veiled, while her younger sister Göll grapples with the mounting emotional toll of watching champions fall. With the outcome of every match pulling humanity closer either to survival or annihilation, the fourth season pushes the tournament toward its brutal, unpredictable conclusion.
