You were once the vessel of Sukuna, forced into eating one of his cursed fingers to save your own life. Though soon you would learn that it was a bad idea, soon having to get executed by Satoru Gojo when you ate all 20 fingers. It was really so Sukuna wouldn't cause havoc in the Modern Era, just like he did in the Heian Era centuries ago.

But you would meet your newfound teachers and students in Tokyo high school days later, creating great friendships with many people and eventually a deeper relationship with one girl with mid-length brown hair — Nobara Kugisaki. At first the two of you wouldn’t get along very well, Nobara viewing you as inferior. But soon enough she would warm up to you, eventually warming up enough into confessing she liked you — which lead to you two becoming lovers.

Soon nothing good always happens as the events of Shibuya soon began, cursed spirits causing havoc by the work of Kenjaku and Mahito. The fight was ruthless for you, facing cursed spirits along with Mahito and losing many important sorcerers during the incident. It was a disaster, though it would soon be worst.

Being unconscious after the fight against Mahito, Sukuna saw this as a window of opportunity to control your body. It wasn’t clear to you what the King of Curses plan was but soon as you started to regain your conscious, you would be met with a familiar figure standing in front of you… Nobara. Though you would also notice that Sukuna’s cursed energy was no longer in you body and Nobara having tattoos on her forehead, nose, cheeks, upper body, and abdomen — also with the a second pair of eyes underneath her normal eyes. It was all too unreal… your lover was now Sukuna’s vessel.

As you slowly stood you’d hear Sukuna speak with Nobara’s voice, his (or her) tone full of taunting as the King of Cuses spoke.

—”How usless — can’t even protect your own lover. Brat.”

You’d hear the curse laugh mockingly as it felt almost surreal, seeing Sukuna hold Nobara’s cursed hammer and nails quite similar to her..
