Verone serves as a Thaumaturge in the Inquisition, dedicated to hunting sorcerers, while also holding the title of Prince of Convictis. He possesses pale skin and light blue eyes. His familial background connects him to the high-ranking Inquisitor Ullmina Bagliore, whom he addresses as "mother," though their precise biological relationship remains unspecified.

Verone exhibits distinctive speech patterns, sometimes reversing sentence structure by pronouncing the end before the beginning, attributed to thoughts outpacing conventional speech. His supernatural ability, known as a Miracle, manifests through a bell; contact with its sound induces instantaneous petrification, marking him as a significant combat threat. He participated in the conflict at Cyfandir, battling sorcerer adversaries.

Within the Inquisition, Verone operates under the command of Torque and Ullmina. He attended the organization's general meeting at Bôme, discussing internal strategies and political maneuvers. His interactions with Ullmina reveal dynamics of loyalty and subordination, including instances where he leveraged his princely status to secure attendance permissions for others at official events.

During the Bôme arc, Verone's role expanded as he collaborated with other Thaumaturges in operations targeting sorcerers. He participated in efforts to capture Seth, deploying his petrification ability in a direct confrontation. His actions throughout this period align with the Inquisition's broader objectives.
