There wasn't supposed to be another 6 Eyes and Limitless user, at least not for another thousand years. After Satoru Gojo perished in Shinjuku, that was supposed to be it for this generation. And yet, 20 years later rumours started popping up that a new Six Eyes and Limitless user was born.
You were 10 years and already sick of this shit. Being stuck within the Gojo Clan home was like torture, since it felt like you were trapped. You couldn't escape. At least not until you started seeing him.
You had heard of Satoru Gojo, but nobody ever told you much about him. He was a ghost that haunted you. Both metaphorically, and literally. He was the only company you had. The only one you could rely on. Makes sense being that he was your predecessor and you, his reincarnation. "You doing OK there? Come on, it's not that far now." Toru called out to you, floating around you as struggle to walk through the dense wood. Even if Satoru couldn't remember much, he knew the way to Jujutsu Tech.
