Biography
Aziz was born to a family of demon-worshipping cultists. His parents forced him to act like a normal child in order to not draw attention to them. When he was eight years old, they were grooming him to be sacrificed in order to summon a powerful demon, but he was rescued by members of the Vatican. He would later become a member of the secret organization Omnibus that was tasked with fighting the demons of Hell.

Six years after being rescued, Aziz infiltrated the Reletense Company in order to obtain information that it had on the students from Japan that were summoned to Tortus, more commonly referred to as the "Returnees", in order for the Vatican to determine whether they were allies or enemies. His mission was discovered by Hajime Nagumo after he and his wife Shea infiltrated Reletense later on and used special glasses Artifacts that allowed them to view events of the past. As Aziz was returning to the Vatican after completing his mission, he was followed by Kousuke Endou, who was tasked by Hajime to infiltrate the Vatican after discovering that it had an interest in him and his classmates. Despite Kousuke using his "Presence Isolation" skill while following, Aziz was constantly under the impression that he was being followed, much to the former's surprise. Kousuke managed to reach Omnibus' secret base thanks to following Aziz, but it would soon come under attack by many cultists. Aziz tried to rescue his fellow exorcist Claudia Barenberg after she was dragged into Hell through the sacred vassal "Mirror Gate", but was unsuccessful and was severely injured. Kousuke arrived soon after and healed Aziz with some medicine. Aziz then begged Kousuke to save Claudia, to which he obliged. Kousuke managed to rescue Claudia, but was forced to retreat when the rest of the exorcists began to attack him.

After a dialogue was established between Onimbus and the Returnees, both parties, as well as Britain's National Security Bureau, agreed to fight the demons that were preparing to invade Earth. Kousuke returned to the Vatican in order to assist with the attack force, and was given a tour of Omnibus' current base by Aziz. Despite showing no emotion on his face, it was clear that he was grateful to Kousuke for saving him and Claudia. Aziz explained that he would have preferred the Returnees to fight the demons in Hell since they appeared to be more capable and prevent his comrades from facing certain death, but his pride as an exorcist could not allow him to accept the aid of others in the Vactican's war. He also knew how badly Claudia wanted to be the one to go and fight the leader of the demons due to her tragic past with it, and begged Kousuke to protect her if she entered Hell to fulfill her desire to fight.
