Fate/Stay Night -Unlimited Blade Works- 18
Holy shit. How did I not see this coming!? It was right there all along, I don't know why I didn't piece it all together!Emiya is Archer!
Heh, I still remember when I figured this out, watching the original Fate/Stay Night anime when it first aired. I seemed like such an awesome plot point back then, and I still like it.
