Jeanne d’Arc, the Ruler-class Servant, hails from 15th-century France as a Catholic saint and military strategist who shattered English siege lines at Orléans during the Hundred Years’ War. Guided by visions of divine sorrow, she forsook her humble origins to command armies, steadfast in her celestial mission to end suffering. Captured and burned at the stake in 1431, she met her demise with unyielding resolve, her final breaths affirming devotion to prayer and service. Summoned as an impartial arbiter in *Fate/Apocrypha*’s Holy Grail War, she merges her spirit with the mortal Laeticia, blending their identities into a singular consciousness. Tasked with preserving the War’s equilibrium, she prioritizes its sanctity over personal stakes, mentoring the homunculus Sieg through ethical trials and opposing Shirou Kotomine’s twisted salvation. Her Noble Phantasm, *La Pucelle*, consumes her existence to ignite sacred flames—a fleeting reprieve against Shirou. Her journey culminates beyond death, reuniting with Sieg on the Reverse Side of the World to voice her love before fading. Amidst the Solomon Singularity, she shields Ritsuka Fujimaru from Flauros’ assault, rallying Chaldea’s allies to quell the regenerating Demon Gods. Uniting former foes against Goetia, she orchestrates defenses to stall the Demon Pillars, emphasizing unity as humanity’s keystone. Post-victory, she dissolves after lauding the coalition’s triumph. Her persona intertwines ironclad discipline with tender empathy, championing justice while treasuring individual fragility. Though composed as a Servant, she harbors quiet remorse over Gilles de Rais’s corruption and tangled emotions toward Sieg. Clad in battle-worn armor and bearing her iconic standard, her Ruler authority manifests as Command Spells etched across her form. Alternate attires—casual and ceremonial—mirror her narrative versatility. Themes of unshakable faith in humanity’s unity, sacrificial resolve, and the friction between heavenly mandate and earthly bonds define her legacy. Across incarnations, she stands as a bridge between mortal strife and heroic ideals, confronting cataclysms that threaten humanity’s fragile order.
