A Certain Magical Index

Agnese explains the ship she is on is known as the Queen of the Adriatic Sea where she and her former group are being punished. She agrees to let Tōma and Orsola escape in exchange for the rescue of Luccia and Angelene, who are at risk of having their brains restructured to avoid casting a certain spell that would allow them to escape. Tōma agrees to help her rescue them, although in shaking hands, he accidentally dispels her magical clothing. As Agnese goes to the flagship to confront the squadron's leader, Bishop Biagio Busoni, Tōma and Orsola manage to find and rescue Luccia and Angelene, who tell him that Agnese is in danger of being used for a spell that would destroy her brain. Just then, the other ships start shooting at them, causing them to fall into the sea, but they are rescued by Index and the Amakusas using an underwater boat. After learning that the spell Biagio intends to use Agnese for has the power to destroys citys and erase their culture, the Amakusas agree to help Tōma and co. rescue Agnese. They launch an attack on the fleet, where they face up against an army of nuns, but when the allied ships try to sink the ship they're on with them, Angeline gets injured trying to keep one of the nuns being killed.
