Fate/Stay Night: Shirou's Third Path

During an accidental surge of magic,

young Shirou briefly “connected” with his future self, who would become the Heroic Spirit [Emiya].

The encounter brought no clear memories. Instead, it left behind two deep-seated instincts in the form of déjà vu and muscle memory.

Under these circumstances,

what kind of miracle can Emiya Shirou create?

The blurb doesn’t do it justice. Read the story.
