Antonia Lirimonie Norfedras Papenorgas Arecroteles Cnorses Morfenoss is a wealthy 12-year-old Greek-American heiress who founded and leads the group known as the "Underside of Kitten Paw" or the "Cat Ear Church." Motivated by boredom and desperation, she established this organization to venerate the Catians, idolizing Eris as the epitome of physical perfection. Antonia stands 1.45 meters tall and weighs 30 kilograms, with blue eyes and blonde hair cut to neck length. Her measurements are 50-45-50, and she is rarely seen without wearing cat ears. She employs two personal maids: Sara, a blonde-haired former mercenary with an eyepatch, and Maya, who has long reddish hair and a cheek scar and uses her connections with the KGB to procure advanced technology. Antonia orchestrates the capture of Kio Kakazu and Eris using her maids, though the plan ultimately fails. Later, after Kio undergoes a temporary transformation into a catboy, she develops a distinct attachment to him. While her leadership and considerable resources drive the cult's operations, its influence remains largely confined to her personal endeavors.
