This scene is where Misaka and Index meet each other for the first time and also part of where the characters are trapped in the underground shopping mall due to some attack.
This is when Index first met Touma and Index wanted to prove to Touma that magic really existed. Look at this video and see something out of the ordinary.
Set to be released on 2013-02-23 (Japan), with the original story written oleh the light novel penulis himself, Kazuma Kamachi and original character desain oleh the light novel illustrator, Kiyotaka Haimura.
This video shows Touma being unfortunate again as he tries to choose between two doors thinking that one of them is the bathroom but later finds out that both are bathrooms ^_^
This video shows the short fight between Accelerator and the teleporter Awaki. Awaki loses miserably to Accelerator despite being in a better body/health condition than Accelerator.
Here anda see Touma and Index getting the wrong idea/conception and Touma ends up getting bitten oleh Index till his head starts to bleed. That's pretty scary if anda ask me.
