Gremlin. A global enemy force that is a fusion of magic and science. It seems this mysterious organization that appeared suddenly after World War 3 is working in secret in Hawaii, America's 50th state. Under the guidance of Leivinia, the boss of the British Golden-style magic cabal called the Dawn-Colored Sunlight, Kamijou and the others head to Hawaii. The group is made up of Kamijou Touma, Misaka Mikoto, Accelerator, Hamazura Shiage, Misaka Worst, and Kuroyoru Umidori. And just as they arrive at New Honolulu International Airport, an attack by Gremlin's magicians begins.
