Eleanor Chalet, a human female in her mid-20s born in 1828, possesses short black hair and piercing gray eyes that shift to blue in select anime depictions. Masquerading as a dutiful maid to Queen Alicia of the Alzano Empire, she dons a green servant’s uniform while covertly advancing the agenda of the Researchers of Divine Wisdom, a terrorist faction where she serves as second-in-command and a necromancer heretic. Her icy composure and feigned loyalty to the crown conceal a cunning strategist who thrives on manipulation and calculated cruelty.

Though she cloaks herself in a facade of calm propriety, Eleanor revels in the thrill of combat, interpreting battle wounds as twisted tokens of desire that blur pain with perverse pleasure. She enforces a paradoxical moral code, executing subordinates who physically abuse prisoners yet orchestrating sacrificial experiments for her organization. Her schemes escalate during the Magic Games Festival, where she shackles Queen Alicia with a cursed necklace to extort cooperation, leveraging the monarch’s life as collateral.

Eleanor’s ambitions pivot on accessing the Akashic Records through Princess Ermiana, alias Rumia Tingel, and spearheading Project Revive Life to siphon mana from captives like Re=L Rayford. In battle, she commands spectral minions and conjures a crimson beast of destruction, deploying barriers to isolate foes and retreating with tactical precision when outmatched. Her scorn for incompetence manifests in sharp ridicule toward failing underlings, though she begrudgingly respects adversaries who challenge her.

Prior to infiltrating the royal household—a maneuver hinting at years of meticulous planning—Eleanor’s past remains veiled. Her motivations mirror the Researchers’ quest to unlock forbidden magical prowess, yet her personal stakes linger unspoken. Within the organization, she navigates a tense hierarchy, enforcing loyalty through fear and disdain while advancing their dark vision without remorse.
