Edward Hamilton (エドワード・ハミルトン Edowādo Hamiruton ), also known by his nickname, Elder (長老（エルダー） Chōrō (Erudā) ), is a scientist of the Order of Magdalene, in charge of weapons development. Elder is the person who makes the weapons used by the exorcists. He also has a great love for women which is why he may appear perverted, though he greatly cares for all the girls. He loves teasing Rosette, but deep down he really cares about her and Chrono and helps them whenever he's able to do it. He was like a father to Magdalene, and doesn't want Chrono to repeat the mistakes of the past.
Elder was involved prior to the initial story involving Mary Magdalene. He was the first one who accompanied Mary from the orphanage and explained her powers to her. He later accompanies the young Ewan in their pursuit of Chrono who kidnapped her from the Order.
