Monica

Monica (モニカ) was a nun of the Roman Catholic Church and later a member of the Guild.

Appearance
During her encounters with Agnese Sanctis in Zurich and Thira, Monica was wearing a nun's habit. While escaping pursuit, she tore off her face with a spell and remained like that to her.

Personality
Monica's personality is largely unknown, though she displayed certain Italian behaviour with her latte. She was willing to tear off her own face, and ensure the destruction of the Guild's records that could be used by attackers to hunt down its members, to the extent of keeping hold of the burning records and being fatally immolated.

Background
Monica apparently acted as a guide for Agnese Sanctis and her fellow nuns several times while they were still with the Roman Catholic Church.

Toaru Majutsu no Index SS: Agnese's Magic Side Work Experience
Monica was spying on Agnese, Lucia and Angelene, while they were in Zurich, Switzerland, visiting an Anglican remote database to investigate a possible link between the recent cases they had been involved in. When they decided to go out for lunch, at a dead end in their research, Monica was a couple of tables away, in the same restaurant they visited and was noticed by Agnese. As Agnese discretely told Lucia and Angelene who was behind them, Monica looked up from her drink, saw Agnese was onto her, and immediately ran out of the restaurant. With Agnese and the others pursuing her, she fled down an alley and used a spell to tear off her face. Though she escaped, her spell gave her pursuers a lead to follow, which led them to mention of a 'guild' in Turin, Italy.

During the Anglican attack on the Guild's base on, Monica was tasked with destroying the guild's spell book, containing records of its members and including a voice sample list on wax tapes. As Agnese, Lucia and Angelene neared her location, she sent a constructed lion at them and used the time it bought to set fire to the records, not letting go even as the flames spread from the papers to her arms. She then ran at the nuns on fire and when Lucia used her wheel to stop her, the burning book was shredded by the wooden scattershot. Despite the destruction, Agnese was able to reproduce the book through the residual information on the burning and dying Monica. When Agnese asked if she had any last words she wanted conveyed to anyone, Monica merely told her to that she'd see her in hell before dying.

Abilities
While escaping from the Agnese Forces, Monica made use of a spell based on folklore from Turin to tear off her face.
