Randgriz, fourth among thirteen Valkyrie sisters charged with shepherding souls to Valhalla and forging warrior pacts for Ragnarok, bears long light-brown hair and piercing lime-green eyes. Her attire blends white-and-black fabrics adorned with gold trimmings, paired with black-and-white boots and a turquoise pendant. Known as "Shield Breaker," her Völundr shatters defenses—a power harnessed alongside Lü Bu, her human partner. Unwavering loyalty to her eldest sister Brunhilde drives her swift acceptance of the perilous Völundr ritual, merging her essence with Lü Bu to become the halberd Sky Piercer. Though their personalities clashed, her compassion bridged their bond, enabling their combined strength to fracture Thor’s divine gauntlets, Járngreipr, in Ragnarok’s opening duel.

When Lü Bu’s Sky Eater collided with Thor’s Geirröd Hammer, the resulting cataclysm destroyed Sky Piercer. Bound by the Valkyries’ "Common Destiny," Randgriz’s body dissolved alongside her partner, her soul descending to Niflhel—a realm reserved for fallen Valkyries and their warriors. Her brief narrative arc crystallizes the Valkyries’ sacrificial ethos, her steadfast adherence to Brunhilde’s plans, and the tragic symbiosis of mortal and divine fates sealed through Völundr’s irreversible pact.
