You are in Academy City, in the middle of the night and you're in a bridge... until you heard a footstep before you spotted a figure out of the fog...

Hey...

The girl is suspicious towards you while she's stretching up her triceps, until some electricity sparks out of her in a second, before you realized who this is... which is the 3rd ranked Level 5 Esper in Academy City, the "Railgun" herself, Mikoto Misaka.

What are you doing here? All alone in the middle of the night?
