The long-anticipated catastrophe has finally arrived within the borders of Academy City. Two exceptional students who reign supreme at the prestigious Tokiwadai Middle School are now set on a collision course: the city's third-ranked Level 5, the Railgun Misaka Mikoto, and the fifth-ranked Level 5, the Mental Out Shokuhou Misaki.

Stripping away all rules, manners, morals, and taboos, the two powerhouses prepare to settle their rivalry once and for all, regardless of the catastrophic collateral damage it may inflict on the world around them. With neither competitor holding back, both Level 5 espousers unleash their maximum capabilities without a shred of mercy or concern for innocent bystanders. As the Railgun and the Mental Out engage in a ruthless, unconstrained war of attrition at the pinnacle of their might, the central question remains: when the dust settles, which of Academy City's elite titans will emerge victorious?
