Fanfic / A Certain Magical Friendship

Go To

What had formed might perhaps be better described as a crack. However, this was not a crack in some wall. This was a crack in the fundamental rules that allowed two completely different stories to be told in the same place. Being forced through a crack in stone might take some skin off. Being forced through this... would have very different effects.

A crossover series by Sora2455 between My Little Pony: Friendship Is Magic and A Certain Magical Index. After Index and Zecora accidentally create a Portal Door between Academy City and the Everfree Forest, things quickly get out of hand when Nightmare Moon crosses over and causes Nightmare Night over there as well.


Different from the host of other portal-based crossovers in that this portal rebuilds whatever travels through it until it matches its destination world. Twilight the unicorn becomes Twilight the cabal magician, and Misaka the Electromaster becomes Misaka, the pegasus who likes to keep lightning bolts in her fur.

The series currently has three stories in it, with the third being written and more planned out. It is cross-posted on Fimfiction.Net, FanFiction.Net, and Archive of Our Own. Links to the various stories are maintained in this google doc.


This series contains the following tropes:

    open/close all folders 

    Context SHIFT 
  • Big Bad: Nightmare Moon for most of the fic.
    • When Index goes into John's Pen mode, however, pretty much everyone agrees that that is a worse problem.
  • Big Good: Celestia, once Touma accidentally releases her from the moon.
  • Land of Faerie: The basis of the magic that created a Portal Door to Equestria, as said in the first chapter:
    there was a certain Celtic myth that if mushrooms were found growing in a circle, it meant that place was an invisible space filled with fae and misfortune; so different that it could be said to be another world. Using that story, along with a handful of store-bought mushrooms, Index could create a circle inside of which counted as 'another world'.
  • Outside-Context Problem: Nightmare Moon shuts off the sun as it's rising over Academy City.
  • Portal Door: A hole in the ground, in both Equestria and Academy City, where falling into it takes people into the other world.
  • Sequel Hook: After the baddies are defeated, the repercussions of changing the plots of both series are expanded on. The Tree of Harmony goes dormant, as nobody bonded to the Elements of Harmony. God's Right Seat want to know just who extinguished their Lord's holy sun. Crowley starts to send the Misaka Sisters into Equestria as scouts.
  • The End of the World as We Know It: Nightmare Moon's Eternal Night, which, by removing the light of the sun, would eventually make it too cold for life to survive.
  • Translator Microbes: Subverted, no magical translation of any kind here. Only the characters who know both Japanese (Neighponiese) and English (Equish) can talk to the cast of both series.

  • Clones Are People, Too: The main theme of this story.
  • Knight of Cerebus: Accelerator, after he rips a Sister clean in half. Right in front of Kuroko and Twlight.
  • Reality-Breaking Paradox: The portal fails to translate Touma; apparently Equestria can't handle Imagine Breaker. When he arrives, the now-ponified Index can only perceive him as a nothing where there should be something. She's able to piece together what he is by logical deduction, and in the process teaches Equestria itself how to handle him.
  • Sequel: Of Context_SHIFT.
