A certain unlikely hero... As battles rage around the world, three boys continue to dash through the fires of Russia. Takitsubo is still suffering, and with no cure in sight, Hamazura relies on a chance encounter and a borrowed jeep to find what he needs in Elizalinan territory. Already there is Accelerator, who awoke in a field hospital after his defeat at the hands of his weakest and most worthy opponent. Though Last Order is no better than before she and Accelerator arrived, it might be just the right place to learn how the occult parchment ties into everything. Back across the border in war-torn Russia, Kamijou is about to infiltrate another military base to finally corner Fiamma. That's easier said than done, though, when two enormous angels turn the entire area into a battlefield!

Protests against Academy City have broken out worldwide, and the never-ending tensions between the forces of magic and science escalate even further. Who truly stands to benefit from the specter of conflict, and can anything be done to prevent the worst-case scenario? Touma travels to France to try to make a difference, but a fierce enemy stands in his way: Terra of the Left, a member of God’s Right Seat!

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!

Seven days have passed since the start of the Daihasei Festival, one of the biggest events of Academy City. Everyone is participating--Seiri Fukiyose is helping coordinate the games, Komoe Tsukuyomi dresses for the part as she cheers for her students, and of course, famous Mikoto Misaka is blowing away the competition. Even Kamijou has appearances! But a shadow has fallen across the celebrations: The Croce di Pietro. This magical artifact threatens the livelihoods of everyone Kamijou holds dear so he dashes off to try and bring Academy City back from the brink. But Oriana Thompson, the magician known as Route Disturb, and the Roman Catholic Church are determined to bring the bastion of science to its knees. Kamijou is going to need all the help he can get-and some luck for once wouldn't hurt!

A certain unlikely hero... It’s another exciting, messy time in Academy City as Uiharu repels a massive hacking attack on the data banks. Elsewhere, Hamazura, Hanzou, and Komaba speed away from the scene of their most recent crime, only to quickly regret their choices after one cop makes it her life’s mission to catch them—no matter the cost in property damage. Meanwhile, in the dark underbelly of the vaunted scientific city, Hanzou must come to terms with his dark lineage or face the consequences. And in that same shadowy world, several Misaka Sisters have gathered for their next mission to…look up their horoscopes?

The horrifying experiment to make Accelerator into an all-powerful Level Six has commenced--and it involves the wholesale slaughter of the little sisters cloned from Mikoto Misaka. Can Touma find a way to stop the seemingly invincible Accelerator? Could it be that weakness is stronger than strength could ever be?
