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!

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!

Accelerator, the most powerful psychic in Academy City, is quietly recovering from his injuries when trouble literally lands in his bedroom. A group of anti-evil zealots who call themselves “DA” are causing havoc, and it could threaten the city―not to mention the entire world! Although he hates to be bothered, a world-shaking threat may be enough to get Accelerator out of bed…especially if it involves the adorable Misaka Mikoto clone, “Last Order.”

Throughout Academy City, the rumors are spreading like wildfire. People are finding mysterious envelopes containing free cash cards in and around the back alleys of the Seventh School District. Whipped up into a frenzy, the populace looks for as many cash cards as they can get their hands on, even if it means braving the perilous Skill-Out Territory, risking injury or worse by roving gangs of Level 0 thugs. Judgement is left with no choice but to step in... While Shirai and Uiharu try to crack the case and figure out who is behind the cash card chaos, Misaka decides to take to the streets herself... and soon gets embroiled in a disturbing scientific conspiracy the likes of which will rock her world to the core.
