A preview trailer for this autumn's TV anime sequel To Aru Majutsu no Index II (A Certain Magical Index 2), which begins airing in Japan from October 2010. This second season is once again animated by studio J.C. Staff, based on the light novel series written by Kazuma Kamachi and illustrated by Kiyotaka Haimura. The story is set in a futuristic world where supernatural powers exist through science, and magic exists through religion. The second season sees the return of the main characters Index, Mikoto 'BiriBiri' Misaka and what's-his-name... bah, irrelevant.
