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!

A certain unlikely hero... Touma Kamijou has gotten permission to leave Academy City and goes on a beach vacation with his family. But somehow no one is who he remembers--and a certain magical spell is to blame for everything! Touma finds himself swept up in the mysterious Angel Fall spell in the latest volume of the smash-hit light novel series!

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?

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!

In the fallout of the attack on Hawaii, the twenty-seven partner corporations that broke away from Academy City announce that they will be hosting “Natural Selector,” a combat tournament in Eastern Europe. By holding the event, the Anti-Academy City faction hopes to prove the existence of powers that surpass psychic abilities, thereby destroying the identity of Academy City. With the help of Gremlin, an organization that merges magic and science, their scheme gets underway. Will Academy City be able to stop them before it's too late?
