Summary
Here is the prequel/side story to this fanfic------->https://ao3-rd-18.onrender.com/works/54254080
Mikoto Misaka may have made the things she did in the anime look easy.
But I never would've guessed that I would be experiencing those events alongside her.
And when you've suddenly taken over the body of a girl, and your sister is the one and only Railgun.
I mean, I guess I'm not named Keiko Misaka for nothing.
And what am I to do, when a certain Sailor Guardian summons me to her out of the blue?
A fanfic that converges with Going In Completely Blind, Going In Almost Completely Blind, & Of Arms And Ammunition.
Credit goes to beta reader/editor Hannah Freestone for helping me out with the first two chapters of this fanfic.
In which the si is thrown into the anime world of A Certain Scientific Railgun. And they have to do their best to help out Mikoto Misaka, all while trying to deal with the fact, that not only are they now a level 5 Esper, but are also the sister to the famous Railgun. Isn't that right Misaka?
