The first Fate/Stay Night-Campione! crossover. A Heavens Feel Shirou finds that himself and Illya have been pulled into another world by a corrupted Grail. There his actions lead to him becoming the Eighth god killing Devil King. Now he has to deal with becoming someone who rules where he walks, even if he doesn't want to. That and trying to find a way back home.

When I sold my soul to the Devil, I thought I was prepared for anything. I wasn't. I didn't expect him to be a her. Or dressed up as a magical girl carrying a pink wand tipped with a cheerful yellow star. Her being a prankster however didn't come as much of a surprise. You know, the Bible would have been a whole lot more interesting if they included stuff like this. Complete AU

Summary: Hikigaya Hachiman, shortly after an odd Valentine's day, finds himself in a new world filled with magic, monsters, and gods. Though he knows not how he got there, he knows that the only way back to his home is through the Dungeon. Also posted on Spacebattles and RoyalRoad.

Shirou was dying. It was a sad truth, but an immutable one. At least it was until Avalon intervened and gave him a chance to continue chasing his fate. Of course, Shirou accepted. Now he's saving people, but not quite in the way that he expected: by exterminating the creatures of Grimm from Remnant. It will take more than a few miracles to change his fate this time around. Semi-AU.
