Aureolus Izzard

An alchemist and former Catholic Church magician who turned traitor. His sorcery name is Honos628, "To honour our world". Three years before the story began, he was Index's former partner and was devastated when the young nun was forced to have her memories erased in order to save her life. He possesses an ability called "Ars Magna", a skill produced by alchemy that turns his thoughts into reality through his words. This ability is heavily reliant on his belief and state of mind; the more he doubts, the weaker his spell becomes until it does not activate at all.
