I died like an idiot.
Rain hammered the alley behind the konbini, turning the pavement into a greasy mirror. Some drunk salaryman swung a broken bottle at me over a spilled pack of cigarettes. I dodged the first slash, but the second caught my throat. Blood sprayed hot across my hoodie. I remember the metallic taste flooding my mouth, the way the world tilted sideways, and the distant wail of sirens that would never reach me in time. Twenty-three years old, no family, no legacy—just a dead-end part-time job and a stack of unread manga on my shelf. Pathetic.
Darkness swallowed everything. Then came the white void.
A figure materialized in front of me, glowing like a cheap LED lamp with too much attitude. It wore a cheap Hawaiian shirt over a cosmic hoodie, sunglasses perched on a featureless face that kept shifting between anime characters I recognized and ones I didn't.
"Yo, loser," the ROB said, voice echoing like it was narrating its own fanfic. "Name's Rob. Random Omnipotent Being. I've been watching your timeline. Real snooze-fest. Car accident? Nah. Mugging? Boring. You went out like a background NPC in a bad isekai. Congrats on the participation trophy for dying."
I tried to speak, but my throat was still remembering the bottle. Nothing came out except a wheeze.
ROB waved a hand, and suddenly I could talk. "What the hell is this? Am I in hell?"
"Hell's for people with personality. You're in the loading screen. Look, I'm feeling generous tonight. Truck-kun's on vacation, so I'm offering a custom respawn. Yoriichi Tsugikuni template. Full package. Demon Slayer's strongest swordsman—Sun Breathing, Transparent World, god-tier physicals, those sick flame birthmarks, the whole calm-unflappable-monster vibe. You get his appearance, his muscle memory, his technique mastery from day one. No grinding. No cheat skill menu. Just raw, overwhelming talent dropped straight into the Jujutsu Kaisen verse."
My brain short-circuited. Jujutsu Kaisen? Curses, sorcerers, Gojo Satoru, Sukuna everything I'd binged last month while ignoring rent. "Why me?"
"Because your death was hilariously mid, and I'm bored. Plus, Yoriichi never got to go full throttle against real monsters. Imagine him with cursed energy instead of just breathing techniques. You'll be a walking natural disaster. Domain Expansion potential off the charts. But fair warning—no plot armor. The verse is brutal. Get cocky and Sukuna will turn you into sashimi. Deal or back to the void?"
I didn't even hesitate. In my old life I had nothing worth missing. "Do it."
ROB grinned with too many teeth. "Smart choice. Transfer commencing."
Light exploded behind my eyes. Memories that weren't mine flooded in—centuries of sword forms burned into muscle, the scent of wisteria and blood, a brother with black flames, a wife's gentle smile cut short by demons. My body twisted, bones lengthening and reshaping. Hair spilled down my back, black at the roots bleeding into crimson tips. Flame-like marks etched themselves across my forehead and cheeks, warm like embers under the skin. Power surged through every vein, cursed energy so pure and dense it felt like liquid sunlight.
Then the void spat me out.
I woke up on tatami mats, ten years old.
The room was traditional Kyoto-style—paper screens, low wooden beams, the faint smell of incense and polished cedar. Morning light filtered through the shoji doors, painting everything gold. My hands, larger now, callused from years of practice—gripped a wooden training sword that felt perfectly balanced, like it had always belonged there. I sat up slowly, calm washing over me like a still lake. No panic. No confusion. Just clarity.
I stood and walked to the full-length mirror propped against the wall. The reflection staring back was Yoriichi Tsugikuni reborn at age ten long straight hair cascading past my shoulders, crimson tips catching the light, those exact birthmarks framing calm red eyes. The orange-to-red gradient haori hung loose over a simple black kimono, hanafuda earrings swaying gently from my lobes. My body was still a child's, but already coiled with impossible strength, taller and more refined than any normal ten-year-old. Cursed energy hummed beneath my skin, denser than anything I'd seen in the manga panels. It didn't rage or leak; it simply existed, vast and controlled, like the sun waiting behind clouds.
A soft knock came at the door. "Yoriichi? Breakfast is ready, dear."
The voice belonged to a woman I instinctively knew was my new mother soft-spoken, dark hair pinned up, wearing a simple yukata. In this world she was thirty-seven, a Grade 3 sorcerer from a minor branch family that had fled the big clans after the Heian era. My father had died to a special-grade curse seven years ago. The family lived quietly on the outskirts of Kyoto, far enough from Tokyo's chaos but close enough to feel the undercurrent of jujutsu society.
I stepped out into the engawa. The courtyard garden was peaceful cherry trees in full bloom, a small koi pond reflecting the sky. Birds sang. Somewhere beyond the walls, cursed energy flickered like a dying candle. A low-grade curse, probably a fly-head type, skulking near the old shrine down the lane. My Transparent World ability activated without thought; I could see the flow of cursed energy in the air, the weak negative emotions coalescing into something ugly.
My mother smiled at me, placing a bowl of rice and miso soup on the low table. "You were practicing again before dawn? You're only ten, Yoriichi. You don't have to push so hard."
I bowed slightly, voice coming out soft and even, exactly like the original Yoriichi's. "It is necessary, Mother. The world is full of shadows."
She laughed gently, ruffling my longer hair. She didn't know the half of it. In this body, Sun Breathing wasn't just technique—it was instinct. I had been training it since the moment the template settled, adapting the eleven forms and the thirteenth to cursed energy over the last decade. First Form: Dance. Second Form: Clear Blue Sky. All the way to the Thirteenth Form that had once burned Muzan to ash. Here, they would carve through curses like sunlight through mist. And if I ever unlocked a Domain Expansion… the thought sent a quiet thrill through me. Something vast, golden-red, a barrier of eternal noon where every slash guaranteed annihilation.
After breakfast I slipped out the back gate, wooden sword still in hand. The Kyoto streets were alive with normal people—salarymen on bikes, schoolgirls in uniforms, the distant rumble of a train. But layered beneath it all was the jujutsu world I now inhabited. Cursed energy lingered everywhere like smog. Most people couldn't see it. I could see everything.
The curse was waiting near the abandoned torii gate at the end of the lane. It was pathetic—a Grade 4, blob-like thing with too many eyes and a mouth full of teeth, feeding on the resentment of a recent car accident nearby. It spotted me and hissed, lunging with clawed tendrils.
I moved.
No wasted motion. Sun Breathing, First Form—Dance. My body blurred, cursed energy igniting along the wooden blade like golden flames. The slash carved a perfect arc. The curse didn't even have time to scream. Its body split cleanly, negative energy evaporating into harmless sparks that smelled like scorched wisteria. One strike. Clean. Efficient. Exactly how Yoriichi would have done it.
I lowered the sword, breathing steady. Not even a drop of sweat. A small crowd of normal people walked past, oblivious. One salaryman glanced at the torii gate, frowning slightly as the residual curse energy dissipated, then shrugged and kept going. Good. No witnesses, no questions.
Back home, I sat on the engawa again, polishing the wooden sword with a cloth. My mother was inside humming an old folk song. I let my mind wander. This world was bigger than the manga had shown. Sukuna's fingers were still out there, sealed and waiting. Gojo Satoru was already making waves in Tokyo as the strongest modern sorcerer. The Culling Games, the Shibuya Incident—events that would shake the jujutsu world were still years away. But I was here now, ten years old and carrying the power to end them all if I chose.
I wasn't going to hide. Yoriichi never ran from demons. I wouldn't run from curses.
But I also wasn't stupid. Revealing myself too early would paint a target on my back. The higher-ups in the jujutsu clans would either try to recruit me or eliminate me. The Kyoto school scouts were already sniffing around families like ours at my exact age. I needed time to grow, to master the fusion of Sun Breathing and cursed techniques. Maybe develop a Domain Expansion that reflected the sun itself—vast, inescapable, burning away all malice in guaranteed hits of solar flame.
A soft breeze stirred the cherry blossoms. One petal landed on my sleeve, glowing faintly with my cursed energy before fading. I smiled, small and serene.
Somewhere far to the east, in Tokyo, the balance of power was already shifting. But here in Kyoto, under cherry blossoms and quiet shrines, a new sun had risen.
I stood, sword resting lightly on my shoulder, and walked back inside.
"Mother" I said quietly, "I think I'd like to visit the shrine today. Alone."
She looked up from her sewing, concern flickering across her face for just a moment before my calm aura soothed it away. "Of course, dear. Be safe."
I stepped out into the afternoon light, cursed energy coiling gently around me like invisible flames. The world of jujutsu stretched out ahead—full of monsters, sorcerers, and secrets.
And I was the sun that would burn through all of it.
