Brunhilde, the eldest of the thirteen Valkyrie sisters, stands defiantly against the assembled pantheons of heaven in *Shuumatsu no Valkyrie*, also known as *Record of Ragnarok*. Every thousand years, the gods gather to decide the fate of mankind, and this time, their verdict is unanimous: total extinction. Refusing to let her mortal charges perish without a fight, Brunhilde interrupts the divine council with a daring provocation, mocking the gods' pride to force them into a final trial. She invokes the ultimate clause of the constitution of Valhalla, a one-on-one deathmatch tournament between the mightiest deities and the greatest champions of human history.

This desperate gamble transforms into a high-stakes struggle where the line between divine power and human spirit blurs. As the arena of Valhalla shakes with the weight of clashes between figures like the Norse god Thor and the legendary warlord Lu Bu, Brunhilde must navigate the internal agony of sacrificing her sisters’ souls to forge the "Volundr" weapons capable of slaying gods. Facing overwhelming odds and the mockery of supreme beings, she remains undeterred by the immense pressure of carrying the survival of all existence on her shoulders. Her unwavering dream is to prove that humanity is worth saving, leading her chosen warriors toward a singular, impossible goal: victory over the heavens themselves to secure another thousand years of life for the world.
