Toaru Majutsu no Index: Endymion no Kiseki

As Academy City nears the completion of its monumental space elevator, known as Endymion, Kamijou Touma and Index cross paths with a mysterious Level 0 girl named Arisa. Their unexpected encounter quickly draws dangerous attention, as magicians launch a sudden assault on the city to capture her. In response to the invasion, a female commander named Shattoaura mobilizes an elite Academy City unit to repel the attackers and defend the metropolis from further destruction. Seeking answers amidst the chaos, Kamijou and Index consult Stiyl, who reveals a startling truth: Arisa is not merely an ordinary student, but the pivotal figure at the center of an impending war between the factions of magic and science. Her existence threatens to shatter the fragile boundary separating these two worlds, making her a target for both sides. As supernatural forces and advanced technology collide, the looming conflict sets the stage for a desperate struggle, with the towering Endymion standing as the ultimate battleground where science and magic finally cross paths.
