Anna, an elf of the Shield of Light, dedicates herself to thwarting the Inferni’s ambitions to resurrect the Dark Lord while guarding magical artifacts from corruption. In Yokohama, she commands operations centered on protecting a potent wand and mentoring those bound to its power. As the elder twin of Chihaya, she carries the weight of their shared history: Chihaya once wielded the wand to end the 1868 civil war by illuminating Edo Castle, a choice that erased her memories and led to her demise. Anna later unravels this past, disclosing how Chihaya stole the wand to prevent its misuse, only to succumb to amnesia.

Tasked with shielding Sonya, the wand’s new guardian after Chihaya’s death, Anna mobilizes allies like Izou and Raiden against the Inferni’s plot to seize the artifact. Her expertise in the wand’s mechanics and the factions coveting it steers their strategy to intercept Kōketsu, the Inferni leader. Post-conflict, Anna orchestrates Sonya’s retreat to Hakodate, the elven realm, cementing the wand’s legacy under the Shield’s guardianship and distancing it from human strife.

Anna’s resolve bridges eras, linking Chihaya’s sacrifice to Sonya’s ascendance as protector. Though she avoids direct combat, her tactical acumen and leadership within the Shield of Light anchor their ceaseless vigilance against threats, ensuring equilibrium endures between light and shadow.
