Jeanne, the Hellfire Witch, serves as a vampire knight under the Oriflamme family. Though chronologically over a century old, her origins remain enigmatic, with a history entwined in ancient vampire conflicts. Her youthful appearance contrasts her battle-hardened past—pale skin, pinkish-white hair, and piercing yellow eyes that flicker crimson under duress. She dons a stark white coat edged in red, a visual echo of her weapon, the Crimson Gauntlet Carpe Diem, which channels devastating white flames and augments her supernatural strength. Molded by strict discipline and childhood trauma—her parents executed for aiding humans—Jeanne internalized a self-perception as a "doll," an instrument of duty. This conditioning fuels unwavering loyalty to Luca Oriflamme, whom she guards with ferocity, and Lord Ruthven, whose manipulative grip tightens through induced bloodlust and cryptic medicinal control. Her curse-like bloodlust binds her to Vanitas, a human whose blood quells her rages, forging a fraught alliance that shifts from hostility to fragile interdependence. Through this bond, Jeanne tentatively confronts emotions long suppressed, even pleading for Vanitas to end her life should she ever spiral beyond restraint. Interactions with Dominique de Sade reveal unexpected warmth, blending camaraderie with bewilderment at Dominique’s teasing flirtations. Social naivety clashes with her lethal combat prowess, underscoring her duality as both a shielded weapon and a guarded soul. Symbolism weaves through her existence: a rose ensnared in thorns within her Mark of Possession mirrors her constrained agency, while cherry blossoms evoke the fragility of her fleeting autonomy. Her tale echoes Sleeping Beauty’s slumber and awakening, tied to Ruthven’s shadowed machinations, though her ultimate role in his designs lingers unresolved. Spin-offs briefly unveil lighter layers—deadpan humor in pastry disputes with Vanitas or bemused participation in cross-dressing antics—hinting at adaptability beyond her solemn wartime persona. Central to her arc is the struggle to reclaim selfhood. Once defined by blind obedience, her bonds with Vanitas and others chip at this identity, sparking defiance against predetermined paths. Yet unanswered questions loom: ties to Luna of the Blue Moon, Ruthven’s endgame, and latent connections to the Vampire Queen all tether her future to a precipice between allegiance and revolt.
