A Certain Magical Index SS, Vol. 2 (light novel) — Kazuma Kamachi

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?
