A Certain Magical Index (or To Aru Majutsu no Index if you're used to the streams) is gearing up for its first foray into feature length films, and there is a very pretty trailer to show for it. Series staples are back again, so rest assured there will be plenty of idol concerts, giant robot monsters and spider-motorbikes. Wait, what? Oh, Accelerator is back. No need to worry!

Strange to see that this is a completely original story, what with all of the light novels that haven't been animated just yet. Still, that's not to say this movie can't be good, and hopefully a good turn-out will secure a third season of Index at a later date. Right after the second season of Railgun, anyway. 

To Aru Majutsu no Index: Endymion no Kiseki tells a story set just before Academy City builds a space elevator. No word as to whether there will be many different kinds of chocolate and Oompa-Loompas, but we'll find out when the film releases on February 23rd.
