Touma Kamijou just can't catch a break. He might live in Academy City, a place full of more super powered students than you can shake a stick at, but his only superpower is his supernatural lack of luck. He wants nothing more than to keep a low profile, but when a girl named Index comes into his life, it gets more complicated and dangerous than ever!

Item’s battle comes to a head as their hideout is raided, and the team reaches its breaking point. Disgusted with Mugino’s disregard for the other members’ lives, Hamazura finds the resolve to stand up to her. Mugino may be a Level Five, one of the strongest espers in Academy City, but she’ll see that even a powerless Level Zero like Hamazura can put up a fight when his back is against the wall!

Violence rages through the streets of Avignon as magic and science clash! Academy City forces are bombarding the city, and Touma has to find the weakness in Terra of the Left’s spell, Light’s Execution, before it’s too late. With all eyes on France, there’s no one watching as the shadow organizations of Academy City rise up, thrusting Accelerator and the rest of Group into a deadly battle royal!

Mikoto Misaka is a Level Five esper--one of the most powerful in Academy City. She's so powerful, in fact, that her DNA has been harvested to create a series of clones--the "Sisters." But who is behind these clones, and why would they go to such lengths? The sinister truth is nothing she or Touma could have imagined, and it involves the terrifying Accelerator, the most powerful esper of all time!

In a staggering battle of electricity versus every super power imaginable, Mikoto Misaka, the third most powerful Level 5 psychic in Academy City, aka "The Railgun", has managed to hold her own against rogue scientist Kiyama Harumi. But Misaka's luck may have just run out. The Level Upper network has given birth to an "AIM Burst", an entity of immense power with one singular purpose--to absorb every last AIM Dispersion Field in Academy City so that it can grow all-powerful. To achieve this, it has set its sights on its next meal: Academy City's experimental nuclear reactor!
