Okkotsu Yuta, The Cursed Prodigy and the strongest second only to Gojo Satoru, found himself winding up in Equestria while on the hunt for Special-Grade Curse in Kenya. However, it seemed like fate had brought him to the colourful land of friendship due to the recent upsurge in cursed spirits. Sprawling like maggots and wreaking havoc. Yuta has no choice but to exorcise or kill all those who stood in his way, with no more than the sword on his back and his ring in hand. Could he find a way back home? Alas, no cursed spirits shall escape the judgment of the second strongest. Wielding the executioner's blade with an impartial attitude.
The events occur several months before The Shibuya Incident and in early 2018. While the Mlp timeline is a couple years after the defeat of Chrysalis, Tirek, and Cozy Glow.
A Jujutsu Kaisen/Mlp crossover. Spoilers for Jujutsu Kaisen 0 and the Jujutsu Kaisen manga.
