A Certain Magical Index (Toaru Majutsu no Index) (2008-09) [BD 720p Hi10P AAC dual-audio][kuchikirukia].

This is пока's excellent encode with the dub added and his ~128k AAC Japanese track replaced by 256k. I also encoded the NCOPs and EDs since they weren't included originally.

Japanese is default. Set your player to eng+zxx to get English audio with Signs.
Note I removed the opening karaoke in the default English sub because I found them to just clutter the screen. I did include a second track that has the subs, so if you want them set your subtitle selection to abk to automatically select that track. (it was the first country code so I picked it for convenience)
