Marguerite Breuil, known as Marie, entered the world in 1793 France amid the Reign of Terror’s chaos. Her birth intertwined with her father’s guillotine execution of a man—coerced by her mother—an act that cursed Marie to decapitate anyone touching her. Mute for her first decade, she shattered silence with sudden, haunting songs of blood and blades, cementing her status as an outcast. At seventeen, she met her demise beneath the same guillotine tied to her cursed origin, ascending as a Transcendence God condemned to wander the Twilight Beach eternally.
Her solitude fractured when Mercurius, an immortal alchemist yearning for death, witnessed her execution. Captivated by her purity, he schemed to elevate her as heir to the universe’s Throne, pitting factions like the Obsidian Round Table against Ren Fujii, a teen who forged a bond with Marie through a guillotine relic. Channeled into the mortal realm via Ren, she exhibited naivete and social ignorance, her lifelong isolation echoing in every interaction.
Though her lethal curse persisted, mitigated only by the Holy Relic Ren wielded, Marie’s innate kindness pierced through her trauma. Captured by Reinhard Heydrich of the Obsidian Round Table, she confronted his faction’s brutality, sparking emotional turmoil as she navigated fear and self-doubt alongside Ren’s battles.
In pivotal timelines, she claimed the Throne as Fifth Heaven’s God, imposing a law of endless reincarnation. Her vision let souls cycle through lifetimes, dissolving societal barriers to nurture collective growth—a resolution granting Mercurius escape from eternal recurrence, though she denied his plea for death. Her reign shattered when Hajun, a cataclysmic force, annihilated her and the Fifth Heaven, yet cosmic forces later resurrected her.
Her Guillotine Curse and reality-altering power, *Amantes Amentes*, mirrored her creed to “love and embrace all,” enabling divine coexistence and mortal reincarnation. Her bond with Mercurius wove manipulation and sincere reverence, as he balanced exploiting her divinity with devout admiration.
