What Fate/stay night: Unlimited Blade Works is
You wake as Shirou, a student who keeps the past hidden and fixes what’s broken. One night an injured girl crashes through your shed and leaves gold after burning your dojo down. Then you remember runs in your blood and the sword in your hands. An Archer you’ve never met answers the summons you never made.
