Although I don't want to be spoiling about the forward unfoldment(I had already finished playing the original game on 2004), but excuse me to talk to the last scene of the OP. The scene shirou reaches archer in the fantastic world with a lot of swords is the symbolic foreshadowing picture with the essence of this great story.
Thanks for building the fun and didactic story. I am looking forward to watching the next episode. I love Fate stay/night[Unlimited blade works].
To the before Review(ep1).
