A Certain Magical Index

Tōma is parachuted into a river and almost drowns but is saved by Itsuwa of the Amakusa Catholics. He explains to Itsuwa that he and Tsuchimikado are trying to find Constantine's Document, also known as the C Document, a magical item that was long ago given by Emperor Constantine to the Pope which allowed whatever the user believes, the people living on Papal Lands also believed it, which Tsuchimikado believes is responsible for the world wide anti-Academy City protest. Bringing him to a cafe, Itsuwa explains the C Document is in Avignon and not in Rome due to the events of the Avignon Papacy and the city's ley lines allows the document to spreads it's magic throughout Europe. However, Tōma and Itsuwa are forced to abandon the cafe after rioters reazlies Tōma is from Academy City. Meanwhile in London, Stiyl and Agnese interrogate Lidvia and Biagio over information on who God's Right Seat are and their goals which Lidvia reveals they are four special individuals who sacrificed their ability to use normal magic in exchange for divine powers so they can rid themselves of Original Sin and become closer with God. As they avoid the rioters, Tōma and Itsuwa gets a call from Tsuchimikado that they need to find one of the city's ley lines so Tōma's Imagine Breaker can destroy the effects of the C Document. Just before Tōma and Itsuwa disrupts one of the site of the ley lines, they are attacked by God's Right Seat, Terra of the Left.
