What If Modulo Yuji Was Trapped in the Prison Realm for 100 Million Years?

Modulo Yuji. 80 years old. Hasn't aged in 68 years thanks to the Death Painting wombs rewriting his biology. Megumi is in the ground. Gojo is in the ground. Every friend he ever had is already buried. And he's hunting one last curse in the Inhuman Makyo before he becomes a cursed object himself. That's when he finds it. A Heian-era prototype Prison Realm — the original blueprint Kenjaku copied a thousand years later. Yuji could shatter it in one second. He's the strongest sorcerer in history. The seal can't hold him. He doesn't break it. He smirks, whispers "veterans don't die, they wither away with time," and lets the realm swallow him whole. What follows is 100 million years of silence. Not 100. Not 100,000. One hundred million years inside a void where time has no meaning, where his Death Painting biology resists the realm's natural distortion, and where Sukuna's residue is still living rent-free in his head from twenty fingers and a thousand fights. And somewhere in that endless silence, Yuji invents something Sukuna never had. A cursed technique that bends time itself. When the Prison Realm finally cracks, Yuji doesn't walk out into 2086. He uses his technique to choose his exit point. He goes back. Past Modulo. Past Shibuya. Past Hidden Inventory. Past the founding of Tokyo Jujutsu High. He steps out into the Heian era. Sukuna's shrine. Mid-massacre. Master Tengen still in his original human form. Uraume frozen with a tray of human limbs. And the King of Curses sitting on his throne, all four arms intact, completely unaware that the man who's about to dismantle him spent 100 million years preparing for this exact moment. What happens next isn't a fight. It's a math equation that was solved 100 million years ago. And the moment Yuji erases Sukuna from the Heian era, every catastrophe in jujutsu history starts unraveling. The Star Plasma Vessel system. Riko's death. Toji's fall. Geto's break. Shibuya. The Culling Game. Every grave that was ever dug — undug, one by one, all the way back to the source. But there's a cost. By the time the smoke clears in the Heian era, Modulo Yuji has erased his own existence. He's alone. A thousand years away from a world that will never come. And Sukuna's twenty fingers are still scattered across Japan, waiting. This is the timeline where Yuji didn't survive the Prison Realm. He weaponized it.
