There was a fine line that divided good from evil. This was not a story of heroes and villains. This was not a story of humans and monsters. It was a story of people fighting for their desires and ideals. And in this battle two boys will fight to determine the fate of two worlds.

The 7 level 5's suddenly wake up within the walls, with new identities, no abilities and a war on their hands the situation is dire. With only their knowledge from Academy City to help them can they find each other and work together well enough without Touma to keep them in line to not only survive in this new world but to win the war.

Have you ever woke up in a hospital with amnesia? Have you ever been alone in an unfamiliar place with unfamiliar people not knowing anything about the world. Mikoto Misaka, the Railgun, 3rd ranked level 5 of Academy City and most powerful Electromaster, killing titans with her ability would be a cinch, now if only she could remember how to use it.
