## Background

At Academy City, Mikoto Misaka was joined by Kuroko Shirai, Kazari Uiharu and Ruiko Saten, as well as Mii Konori and Misaki Shokuhou, as she helped in performing an experiment that aims to create new kind of metal using a large amount of electricity. (Unknown to her friends, she was merely doing it for the sake of rare Gekota merchandise.) Despite Uiharu's worries about rumors of a "door to another world" hidden somewhere, Mikoto proceeded with the experiment.

Moments after they were engulfed by a blinding light, they suddenly found themselves outside of the experiment venue, where unfamiliar creatures were attacking civilians. Meanwhile, Mirja joined Mai and Maki to make a report of "civilians" fighting Aradama. Kanami, Kaoru, Chie, Kofuki and Sanae were deployed to respond to the unusual turn of events, while Maki found herself compelled to join the frontlines to find out what is going on.

Kanami's group encountered the unfamiliar girls fighting the Aradama in the area and quickly suppressed the Aradama threat. Minutes later, they accompanied Mikoto and the others to Maki and Yume, who were puzzled about how little this new group know about Aradama and Toji. Mai explained the role of Toji in suppressing Aradama. In turn, Mikoto and the others revealed that they originated from Academy City, where students develop esper abilities. After a short exchange of introductions, Maki agreed to provide Mikoto's group a place to stay at Renpu Girls' School. Mikoto then recalled the events that happened before they were transported into "a world without esper abilities". Here, she mentioned that the experiment was supposed to create a metal that was given the temporary name "tamahagane", which is coincidentally the name of the metal used to forge okatana. Maki suspected a link between the two metals, but Mai decided to leave this part of the investigation to Ellen and the Special Rare Metals Utilization Research Institute.

Mikoto's group remained for several days and agreed to help in retrieving the tamahagane metal from the Aradama slain by Toji. With Uiharu's analysis of Renpu's data, the exact location of Aradama that drop the tamahagane metal was discovered, allowing someone like Yume to be quickly dispatched to the area with the help of Kuroko. This cooperative approach between Mikoto's group and Kanami's group continued until one day, the unit composed of Chie, Kofuki and Kaoru and accompanied by Mikoto and Kuroko found a large gathering of Aradama. Kanami and the others soon arrived to the unit's location for reinforcements.

With the combined efforts of Kanami's group, Mikoto and Kuroko, a large amount of tamahagane metal was obtained from the mission. Ellen also arrived to tell them that the tamahagane metal they are gathering easily bonds together when exposed to electromagnetic waves. This opened the possibility that Mikoto's electricity may somehow be attracting the Aradama with such metal in their bodies, and Maki suggested using this opportunity to gather all the remaining Aradama in a large operation.

The next day, contrary to the initial plans for the operation, large amounts of Aradama appeared at the place where Mikoto's group first appeared. Kanami's group continued with the plan regardless, while Mikoto and Kuroko crippled the Aradama with the use of the Electromaster's electricity. Misaki also helped out by using her mind control ability to aid in evacuation efforts. With things going as planned, Mikoto decided to use her full power to defeat the Aradama that are expected to gather towards her location. Then, as the Aradama combined into a much larger one, Kanami and the others faced the larger enemy together.

After gathering the tamahagane metal from the last operation, Mikoto and the others realized the end of their adventure in Kamakura. After voicing their gratitude for the experiences they had during their few days in a different world, Mikoto used her powers over electricity to trigger the same events that would bring them back home. Although unsure about whether Mikoto and the others were successful, Chie suggested praying for their safety. Meanwhile, Kaoru and Kanami remarked about the possibility of "all kinds of worlds out there" and the people who live in them.
