God_Of_Brutality
I would definitely recommend this fan fic to most people as the author creates an easy to understand world background (I have never watched fate except stay night and could easily understand the kingdom aspect) and the characters have proper personalities and not just your average everyone is in love with MC cliché. Sorry if this was confusing not great at reviewing :p
honestly one of my favorite FF novels I love it only thing i disliked was the constant plugging of his discord but i for used to it he is a great author ps. author-sama dont listen to the haters saw you ranting about it on one of the chapters you there will always be people trying to ruin others fun
