The Fuyuki Grail War lasted longer than it ever should have. But...maybe that wasn't so bad? Their parting had been more painful than Shirou Emiya had ever expected, but in a strange sense, maybe both their wishes would come true after all? Of course, he should have read the fine print—as a certain magus once said, "Every miracle has a price."
"There is no regret, and I don't have anything I forgot to tell her. That parting contained everything. What I wanted to do. What she dreamed of. It was a competition of our determination, and maybe I should have taken her hand and granted her dream." A few different choices lead to a surprising end to the Fifth Fuyuki Grail War. Perhaps you will be able to grant her dream, Shirou.
