Lucia

Lucia (ルチア Ruchia?) is a Roman Catholic Church nun who is a member of the paramilitary force know as Agnese Forces, which is led by her friend Agnese Sanctis. A girl with a mysterious past, she is loyal and devoted despite her cold exterior. She is first introduced in Toaru Majutsu no Index as an antagonist, the foil to her timid and bumbling partner Angelene, but later reforms and joins Necessarius, and is a representative of Roman Catholicism in England. After the war, with better relations between the Churches and after much effort by the Agnese Forces, the group later returns to the authority of the Roman Catholic Church.
