Borrowed Time (jujutsu Kaisen x male reader)

Follow the story of the deadliest plague the Jujutsu world has ever seen. The story of a Foreigner who is forced into a world blood and death for which he has little knowledge about, in a land he hardly knows, the Heir to Japan itself, and a legendary blacksmith whose very name would shake the jujutsu world to its core. These three men would forever be remembered as the ones who annihilated a curse no human thought they could ever hope to outsmart, let alone beat. I speak not of the king of curses...but the King of Plagues himself.
