A Certain Magical Index NT, Vol. 3 (light novel)

A star-spangled team up...Gremlin, a belligerent organization fusing magic and science, is operating behind the scenes in Hawaii, developing a plot to take over the American government. As a result, Touma Kamijou, Mikoto Misaka, Accelerator, Shiage Hamazura, Misaka Worst, and Umidori Kuroyoru head to America’s fiftieth state under the guidance of Leivinia Birdway, leader of Dawn-Colored Sunlight. But no sooner do they land at New Honolulu International Airport than Gremlin springs a surprise attack on them. Fortunately for Kamijou and company, one man has already clued in to Gremlin’s schemes and is trying to take it down himself—Roberto Catze, the president of the United States!
