Virtuosa (Arknights) - Laterano Nightclub

Arturia Giallo is the distant cousin of Federico Giallo the Executor and is noted for her musical talents since childhood. She was raised alongside Federico, as she is the daughter of Marcello, the cousin of Federico's father, and Luciana. Federico regarded her as a sisterly figure. However, her Arts convinced her mother to become a wartime photographer, and Arturia was accused by her father of causing Luciana's tragic death. During Luciana's funeral, Arturia's Arts affected the attendees, creating chaos. Afterwards, her father distanced himself from her, sending her to Leithanien for musical studies where she was mentored by a Witch King loyalist and her Arts grew even stronger.

Arturia's unrestrained character is driven by her strong desire to liberate people from the fetters of their own suppressed emotions. Her mastery in music, notably the cello, allows her to wield a rare form of Arts, combining music with her Sankta-enhanced empathetic abilities. This manifests as ego-liberation Arts, which awaken hidden and repressed desires within her listeners, compelling them to act on them without fear or regret. However, this often leads to tragic consequences as listeners may pursue their desires to the point of self-destruction or even harm others, making her abilities a significant threat to people. Additionally, her skill in manipulation enables her to convince people to listen to her performances willingly, as well as evade dangerous situations. Her philosophy, rooted in emotion and desire, starkly contrasts with that of her cousin Federico, who operates solely on cold logic, making him the only one who can remain unaffected by her Arts.

In 1092, several Sankta patients in a sanatorium developed irregular empathic disorder after listening to Arturia's performances, turning her into a wanted criminal in Laterano and prompting Federico to take it upon himself to apprehend her. However, even as a fugitive, Arturia continued her quest. She manipulated Chief Justice Marshall of Columbia to declare himself as "Emperor of Columbia" who demanded Infected rights, sparked a revolution in the palaces of Sargon that led to the execution of a Lord Ameer, and inspired a unit of Victorian soldiers to desert following the purge of a Taran nationalist secret meeting. Inspired by her mentor, she found refuge in Leithanien where she quietly collaborated with the Echoes of Herkunftshorn to fulfil one of her goals — to personally meet the Witch King and seek answers from the greatest caster in history. To achieve this, she disguised herself as a guest of Werner von Hochberg, the Kurfürst of Sturmland and Viviana's father, and stole a copy of the Güldenesgesatz, a key document aiding in the Witch King’s revival. Her actions even earned the attention of the Twin Empresses, making her arrest a potential diplomatic crisis between Laterano and Leithanien.

At one point during her stay in Leithanien, she coincidentally became Kreide's musical teacher, unknowingly teaching the cello to a boy who harbored the "Voice of Mundane."

After the Stimmverlust of the year 1100, Arturia was formally taken into custody by Federico after prolonged diplomatic discussions with the Leithanian imperial court. Despite her crimes, however, the Lateran Curia did not formally sentence her, as the Law found her not guilty. Instead, she was made a Saint of Laterano, the nation's highest title akin to the Pope, by Pope Yvangelista XI. The Pope believed that her profound understanding of emotions could play a crucial role in preserving the Sankta race in the face of an impending Apocalypse. Due to her controversial status, Arturia remains under soft detention at Rhodes Island where she operates under limited freedom as Operator "Virtuosa", awaiting her ultimate judgment by the Lateran government.

Arturia is a Sankta with a hovering black halo above her head and striking, wing-like formations that stretch from her back, shaped like shards of black crystal. Her sleek, straight black hair cascades far past her waist, framed neatly by blunt-cut bangs, and her deep, jet-black eyes add to her striking appearance. She wears a white asymmetrical coat draped stylishly over a dark pleated skirt, complemented by delicate lace-trimmed thigh-high stockings and sleek black gloves. Arturia has a slender figure with C Cupped Breasts and a nice ass. She usually carries a Cello with a long stringed bow in her hands.
