Ep 14. City of Water

In A Certain Magical Index season 2 episode 14, titled "City of Water," the story follows Touma Kamijou as he travels to Italy to meet his British friend, Stiyl Magnus, and a powerful nun named Agnese Sanctis, who have both come to investigate a strange disturbance in the city of Venice.

As they arrive in Venice, the trio finds themselves in the midst of a conflict between two powerful factions: the Roman Catholic Church's Agnese Forces and the Aqua of the Rear, a group of magical users with connections to the city's canals and waterways.

Despite their differences, both groups seem to be working towards a common goal: finding a powerful magical artifact known as the Document of C. Rumored to grant incredible power to whoever possesses it, the Document has attracted the attention of both factions, as well as a mysterious group known only as the "Dawn-Colored Sunlight".

As the three friends begin to investigate the situation, they quickly realize that there is more going on than meets the eye, as they encounter a variety of magical beings and engage in several intense battles against the forces of the Aqua of the Rear. At the same time, they also start to uncover some unsettling truths about the Catholic Church's Agnese Forces and their questionable methods.

But with so much at stake, including the fate of the Document of C and the future of the magical world, can they really succeed against such overwhelming odds? Only time will tell, as the thrilling story of A Certain Magical Index season 2 continues to unfold.
