The Promise of The Sheathe

Emiya Shirou, a man who once walked the path of a hero, has spent years honing his craft, seeking a miracle that could defy the very fabric of fate. Bound by an unshakable love, he has long yearned for the return of the woman he once held dear-Artoria Pendragon, the King of Knights.
But when she opens her emerald eyes, there is no recognition, no warmth-only the gaze of a knight who does not know his name.
To her, he is just another mage, another Master, another wielder of Command Spells. The love they once shared, the battles they fought together, the dreams they entrusted to each other-all are lost to the sands of time.
