A Certain Divine Visionary

Academy City of Science and Technology. A city containing about 2.3 million citizens with 80% of that population consisting of students, and home to two rival forces: Science and Magic. The conflict between Science and Magic has always been prominent, but when one group accidentally resurrects a menace from another world, not just Science and Magic are at stake; the world at large is put in danger. Hope is put into the heroes of the city, including the third-ranked Level 5 esper Railgun, Misaka Mikoto, and Kamijou Touma, the Imagine Breaker, but they can't handle the fight themselves. When Misaka is saved by a boy wielding a sword with a shining blue light, she realizes that this battle is bigger than the two can handle.

First of several stories in the Xenoverse Chronicles Series, a series in which Shulk and company visit other universes to stop Zanza from conquering foreign worlds.

I do not own Xenoblade Chronicles or the Certain Scientific/Magical series, this is a fan story.
