Search Worlds Without End

A short-lived respite...After bringing an end to World War III, Touma Kamijou disappears from the world. Both sides--magic and science--take time to rest and regroup. Accelerator distances himself from his troubled past and adjusts to living an ordinary life with Last Order and Misaka Worst. Meanwhile, Shiage Hamazura uses the secrets he gained in Russia as a bargaining chip and returns to Academy City to re-form Item. It seems like peace is here at last. That is, until a new group called the Freshmen bursts on the scene, forcing Accelerator and Hamazura back into contact with Academy City's underworld...

Danger Overhead... As the dust settles from their encounter with the Freshmen, Touma Kamijou, Shiage Hamazura, and Accelerator finally cross paths in Academy City. Before long, these three find themselves with yet another challenge on their hands--explaining what the heck they've been doing to everyone who was worried about them! Amid this series of reunions, Birdway gives Kamijou and the others a crash course on the fundamentals of magic and warns them about a new threat that has emerged from the ashes of World War III. Meanwhile, Kanzaki takes to the skies on behalf of Necessarius to investigate a floating fortress... and discovers that it's set to collide with Academy City! Can the worlds of science and magic coordinate in time to prevent disaster?

Gremlin, a belligerent organization merging magic and science that formed after WWIII, is operating behind the scenes in Hawaii. Under the guidance of Leivinia, leader of Dawn-Colored Sunlight, Touma Kamijou, Mikoto Misaka, Accelerator, Shiage Hamazura, Misaka Worst, and Umidori Kuroyoru head to America's 50th state. 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 into Gremlin's schemes and is trying to take them down himself--Roberto Katze, the President of the United States!
