Lidvia Lorenzetti, a high-ranking Roman Catholic Church figure, navigates conflicts between Science and Magic through radical evangelism and strategic acumen. Born and raised within the Vatican’s shadow, she prioritized gospel dissemination over hierarchical ascent. Her methods involved recruiting outcasts—criminals, cult members—harnessing their latent talents to amplify the Church’s reach. This unconventional approach earned her the moniker *Mardi Gras*, symbolizing her fervor for conquering obstacles.

Her striking appearance—long pale blonde hair, piercing blue eyes, and a white hooded robe emblazoned with a red cross—mirrors her unyielding devotion. Devout yet pragmatic, she sacrifices allies without hesitation to achieve her goals, confronting adversaries like Laura Stuart with ironclad resolve, even under duress. Pressure heightens her intensity, her demeanor growing increasingly volatile as threats mount.

During the Daihasei Festival, she masterminded a scheme to seize Academy City using the Croce di Pietro, a relic requiring starlight activation. Oriana Thomson served as a diversion, drawing attention while Lidvia positioned the artifact beyond the city’s borders. Artificial festival lights disrupted celestial alignment, foiling her plan. Though evading capture initially, Anglican forces eventually apprehended and interrogated her.

Imprisoned in the Tower of London alongside Biagio Busoni during the Document of Constantine events, she bartered intelligence on God’s Right Seat—a clandestine Catholic faction seeking to purge original sin—to secure prisoners’ freedom. Her alliance with the marginalized shaped this choice, reflecting tangled loyalties between personal ideals and institutional agendas.

Earlier, she sold a platinum staff gifted by the Pope to finance evangelical missions, exemplifying her pragmatism in channeling resources toward objectives over symbols. Her aptitude for controlling volatile operatives cemented her influence within the Church, even as superiors decried her disruptive tactics.
