The Dragon Curse [JJK Male reader insert]

What if after many years of staying with him your King Sukuna sends you to the mortal realm to watch over his future vessel? and what if you are forced to become a jujutsu sorcerer?

(A/N: This story includes the theory that Yuji is the reincarnated version of Sukuna and is also on my Wattpad account @1-800-KILL-ENDEAVOR)
