Brunhilde, eldest of thirteen Valkyrie sisters, orchestrates the Ragnarök tournament—a clash between gods and humanity to decide mankind’s survival. Tasked with recruiting and training legendary human warriors, the Einherjar, she pairs each with a Valkyrie through Völundr, a bond transforming the sister into a weapon matching the fighter’s combat style. This pact risks the Valkyrie’s annihilation should their partner fall.

Driven by defiance toward divine rule and a resolve to protect humanity, she maneuvers with calculated precision, deploying morally ambiguous strategies—coercing Valkyrie siblings into perilous alliances and enlisting figures like Jack the Ripper to secure victories. Yet beneath her icy pragmatism lies concealed vulnerability: she privately mourns losses at a shrine honoring fallen comrades, her grief veiled from public view.

Strategic recruitment defines her approach, from the indomitable Lü Bu to Adam, whose mimicry of divine techniques proved invaluable. Her foresight emerges in alliances like Buddha, whose Völundr insights she secured pre-tournament. In battle, she balances ruthless resolve with buried guilt—publicly stoic after Heracles and sisters perish, yet grieving in solitude.

Mythological threads weave through her past—ties to Siegfried of Norse legend and charged exchanges with Odin—implying hidden agendas beyond humanity’s salvation, possibly rooted in ancient grudges or unresolved divine rivalries.

Adaptability anchors her leadership; she recalibrates tactics against wildcards like Zeus. Mounting losses strain her resilience, manifesting in stress-fueled binges on Nordic salmiak pies—a private ritual contrasting her public command. Together, these layers depict a leader forged by ideological fervor, private remorse, and shadowed histories.
