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?

A DEMON IN THE DUNES With their rigorous training session behind them, Satou’s party is finally prepared to take on the tougher enemies of the Celivera Labyrinth. Never ones to shy away from a side quest or two, they also find a hot spring and open a Japanese-style inn on the spot. Areamasters and floormasters beware! This group is refreshed and ready for battle! Unfortunately, the opponent who finds them turns out to be someone nobody saw coming…

Showdown in Castle Town! Having successfully averted the airship attack, Satou and company arrive safely in the royal capital. There, they are reunited with Nana’s “sisters”—Numbers 1 through 8—and give them the gift of a lifetime. But as is tradition with every trip to the capital, Satou must rub elbows with the aristocracy before he can enjoy his sightseeing. He even receives a surprise visit or two, including a summons from Sir Juleburg of the Eight Swordsman of Shiga! Because no leisurely trip would be complete without a friendly duel…

RISE AND GRIND! ​Desperate to protect those close to her, Zena approaches Satou with a simple wish: She wants to become stronger. Naturally, Satou agrees to help, and he and his party subject her to training so rigorous the other explorers can hardly believe her growth. Not one to be left behind, however, Karina enrolls herself in their Labyrinth boot camp as well! But they’ll need to be quick about it. Satou is due in the royal capital, and if his luck is anything to go by, it’s only a matter of time before trouble rears its ugly head!

“I wasn’t expecting you to be in cahoots with the queen, that’s for sure.” Having defeated Kyo and left Kizuna and the others behind, Naofumi and his friends return to Melromarc. The Spirit Tortoise has left a deep scar on the world’s nations, including their own Melromarc. Now with the objective of preparing for future struggles against the waves and the deadly Phoenix, for some reason Naofumi heads straight to the slave trader?!

A certain unlikely hero... In Academy City, where superhuman abilities are scientific reality, Touma Kamijou is trying to reconstruct a life for himself, but that's easier said than done with a girl by his side with the arcane knowledge of 103,000 grimoires rattling around in her brain... Now seemingly inextricably caught up in a world where magic is a reality, Kamijou learns that a certain shrine maiden is being held captive in one of Academy City's cram schools. Can Touma ally himself with a sorcerer who has on more than one occasion tried to do him in? The only thing he knows for sure is that he really does have rotten luck...

As the dust settles from their encounter with the Freshman, Touma Kamijou, Shiage Hamazura, and Accelerator finally cross paths in Academy City. It won’t be long before these three find themselves with yet another challenge on their hands—explaining what the heck they’ve been doing to everyone who was worried about them! The boys have survived more than one scrape with death but it’s anyone’s guess if they’ll live through this...
