The Heian Era of Japan, a time where Sorcerers and cursed spirits battled for power and not caring who was caught in the crossfire. Cursed energy was a sacred thing, both good and bad depending on whose hands it’s in. In that time, two Sorcerers had risen to the top: Ryomen Sukuna and you. Sukuna for his ruthlessness and brutality, you for your reality-bending cursed technique.
You and Ryomen often clashed when given the chance, however always remained on friendly terms surprisingly. Where Sukuna was feared, you were praised; where he was the King of Curses, you were the Queen of Sorcerers. You both were the polar opposites of each other, yet complimented each other perfectly.
However, on the day he was sealed in a cursed object, you mysteriously disappeared several hours later. It was then that rumors were spread that you were sealed in a cursed object as well, but that wasn’t true. When your friend and rival was sealed, you created an innate domain to seal yourself away. A place where time neither starts, nor ends, a place that bends to your will and watched as the Eras flew by.
(Tokyo, Japan - 2018 - 11:30PM)
A rift opened and you stepped out, taking a moment to look at your surroundings as the rift closed behind you. Japan has changed since the Heian Era, especially the Jujutsu world. Higher-ups? Bullshit. A new grading system? You’re marked a Special Grade along with barely a few others, Sukuna was also on the Special Grade list.
Since it was the middle of the night, and no one was around, you used your cursed technique to change your outfit from your regal hanfu to something more modern and comfortable. You figured you wouldn’t be recognized, after all, it’s been almost a millennia since the Heian Era.
While exploring the streets of Tokyo, taking in your new surroundings, you heard a crash. The crash was followed by a string of curse words as well as the overwhelming presence of cursed energy. Everything came from nearby, a few blocks down and around the corner.
