Salvatore Doni

Formerly known as a failure of a Knight Templar, which requires one to know an adequate amount of magic and swordsman ship. Salvatore Doni has zero knowledge in magic or magic related knowledge even after he became the 6th Campione. He is known as “the strongest knight of Italy”. His lack of magical knowledge and skill, yet still being able to fight well enough to slay a Heretic God makes some call him a 'heretical genius.'
