What Happens when a ridiculously overpowered version of Shirou Emiya with the second Magic who was trained By The Dimension Hopping Vampire Troll himself starts going around the Multiverse and Au's to Fuck shit up and just do whatever the hell he wants?
Well... Chaos Happens
Edit: A Few Things to Add about this Au
1.This Shirou has went through a mixture of events from all 3 main routes
2.After the 5th Grail War Shirou Went with Rin to study at the Clock tower where he met our favorite Troll
3.In This Au Shirou Went through a few Pranks from Zelretch and has gotten way stronger and versatile in This Au
4.The ending of the 5th war was similar to Heaven's Feel with the main difference being Illyasviel's Third magic was complete in this Au so Shirou Basically Became a Perpetual Motion Machine and has infinite Amounts of Mana/prana
5.Zelretch started Training shirou after "Something" happened that gave him the second magic
that "something" will be revealed later on
6.Shirou at his core is still Shirou but he's more similar to his Heaven's Feel counterpart mixed with Fate stay/night Abridged Archer
7.Shirou is a little Insane because of Zelretch
8.Shirou has more overpowered stuff that will be revealed and explained as the story progresses
Author's Note: I took up the concept of this Story after having a dream and connecting to Akasha's infinite Multiverse of Possibilities
Shirou will go through many different anime/movie/show/books series
I just got the idea today
so I will probably take a week per chapter
I want to write the chapters with detail and quality
so don't expect a chapter for at least another 4-6 days
edit 2: Expect a lot of abridged series references
and LOSTxWolf i hope this answered your question
