Cariot holds the role of a clergyman within the Vatican’s covert Anti-Creed organization, Fatima, acting as both superior and caretaker to Clarus Tonitrus. Tasked with overseeing her missions and maintaining her stability amidst her fragile mental state, he meticulously manages her daily routines and logistical needs—a duty that once led to an unintended misstep when his unfamiliarity with Japanese culture resulted in booking a love hotel, a mistake he earnestly sought to atone for. Trained under the Church Militant doctrine, he confronts supernatural threats without relying on innate powers, instead wielding refined combat expertise and strategic precision. His striking appearance aligns with the Long-Haired Pretty Boy archetype, featuring chest-length gray hair and vivid green eyes. While consistently composed, his demeanor exhibits a pragmatic flexibility that contrasts with Clarus’s rigidity, allowing him to navigate duty and adaptability with balance. Unwaveringly loyal to Fatima’s mission, he dedicates himself to containing the malevolent entities known as Nights, prioritizing the organization’s objectives above all else.
