The silence of the Minato penthouse was a different kind of quiet than the one I'd grown up with. In the Kamo estate, silence was heavy, like a shroud; it was the sound of people holding their breath so they wouldn't offend an elder. Here, the silence was airy, punctuated only by the distant, rhythmic hum of Tokyo's late-night traffic and the soft whir of the climate control. I lay on the bed, staring at the ceiling, my fingers tracing the edge of the black debit card. Sixty million yen. It was a lot of money for a twelve-year-old, but in the world of sorcery, it was barely a down payment on a decent Cursed Tool. I wasn't going to be a civilian. My father knew it, Shizuka knew it, and I certainly knew it. You don't give a 'civilian' a servant who can exorcise Grade 4 curses and a penthouse with reinforced windows. You give those things to a problem you want to keep comfortable and far away.
I closed my eyes, and thanks to the Defiled Mind buff, my thoughts didn't wander. They marched. I began to sift through the mental filing cabinet of my childhood. Being the 'spare' heir meant I had spent a lot of time in the Kamo archives, reading books I wasn't supposed to touch. I thought about the Zen'in clan's Projection Sorcery. It was an incredible technique—pre-determining twenty-four frames of movement per second. It turned the user into a high-speed blur, a human cinema reel. For a second, I felt the itch of envy. If I had that, I could outrun my past. But then, the cold, analytical side of my brain—the 'Defiled' side—shut the idea down with the clinical efficiency of a guillotine. First, my Cursed Energy reserves were pathetic. I was a flashlight running on a single AA battery; Projection Sorcery was a stadium floodlight. I'd burn out before I finished my first step. Second, the Zen'in were litigious bastards. If a Kamo outcast showed up using a bastardized version of their crown jewel, they wouldn't send a letter of protest; they'd send an assassin. No, I needed something original. Something that didn't play by the rules of 'fast' or 'strong,' but by the rules of 'No.'
I wanted a technique that defined my new life: independence. Total, absolute denial of the world's ability to mess with me. I pulled up the System interface in my mind's eye, the blue light reflecting off my irises. The Cursed Technique Creation (CTC) slot was pulsing, waiting for input. I began to visualize the concept, weaving it out of the raw logic the System provided. I didn't want to move fast; I wanted the world to stop. I imagined a camera shutter, clicking shut and trapping a moment in amber.
The first technique began to take shape, and I named it Stillframe Sovereignty (静止支配). I poured the requirements into the System: it had to be a visual authority. If I could see it, I could dominate it. The core function was simple but terrifying: the absolute halt of progression. Anything I focused on would be locked in an immutable state. No movement, no energy transfer, no time passing for the target. If a fireball was coming at me, I wouldn't dodge it; I'd freeze the space it occupied, turning it into a beautiful, harmless glass sculpture mid-air. I added the layers of complexity—Selective Freezing for when I needed to be a surgeon, and Layered Frames for when I needed to be a jailer. I felt the System groan under the weight of the logic. It was a high-risk technique; the strain on my eyes and brain would be immense, and if I tried to freeze something with more output than I could handle, the 'frame' would shatter, hitting me with the force of everything I'd tried to stop. But that was the point. It was a gambler's technique, and I'd already lost everything once. What was a little neurological feedback?
I hit 'Create' on the interface. A 'Buffering' icon appeared, spinning in the center of my vision. It felt like a low-voltage current was passing through my optic nerves, a tickling sensation that made my eyes water. After a few agonizing seconds, a chime rang in my head. [CONGRATULATIONS. CURSED TECHNIQUE 'STILLFRAME SOVEREIGNTY' HAS BEEN VALIDATED BY THE LAWS OF THE WORLD. INTEGRATING...]. A flood of instinctual knowledge washed over me. I knew exactly how to squint my eyes to 'catch' a target. I knew the weight of a frozen moment.
But I wasn't done. Having a god-tier defensive technique was useless if I ran out of juice after ten seconds. I had one slot left, and I knew exactly what the 'old' me lacked: growth. In the Kamo clan, you were born with a certain amount of Cursed Energy, and that was basically your ceiling. It was a biological lottery, and I'd pulled a losing ticket. I wanted to change the game. I thought about the old legends of cultivators, the men who sat under waterfalls for a hundred years to turn their breath into lightning. If the world wouldn't give me more energy, I would take it. I would harvest it.
I began to draft the second technique: Heavenly Cycle Cultivation (天循栽術). This wouldn't be a combat technique in the traditional sense. It was an ecosystem. I defined the parameters: the ability to absorb, refine, and permanently assimilate external Cursed Energy. I wanted to be able to siphon the residue off Cursed Tools, to breathe in the ambient negativity of Tokyo, and most importantly, to condense the remains of exorcised spirits into 'Cursed Cores.' I imagined my body as a refinery, taking the crude, oily energy of the world and distilling it into something pure, something that belonged only to Arata.
I added the False Zenith state—a meditative trance where my bodily needs would vanish, allowing me to process energy for days without food or sleep. It was a lonely technique, suited for someone who lived in a penthouse and didn't plan on making friends. I felt a strange, cold joy as I finalized the 'Backlash' settings. If I got greedy and absorbed too much, it would tear my pathways apart. It was a fair trade. Power for discipline. I hit 'Proceed.'
The second integration was more violent. My entire body felt like it was being dipped in ice water, then boiling oil. My heart rate spiked, then plummeted, as the Heavenly Cycle began its first, empty rotation through my meridians. The System chimed again. [CURSED TECHNIQUE 'HEAVENLY CYCLE CULTIVATION' CREATED. SLOTS: 2/2. QUEST 'THE FIRST SPARK' COMPLETE. REWARDING 50 EXP AND CURSED ENERGY BOOST.]
Suddenly, the 'AA battery' inside my chest felt like it had been swapped for a C-cell. It wasn't much, but the flicker of energy was steadier, brighter. I sat up, my breath hitching. For the first time in my life, I didn't feel like a hollow shell. I felt like a machine that had finally been plugged in.
"Let's see if I'm a genius or a corpse," I whispered. My voice sounded different—more resonant, more certain.
I reached over to my bedside table and grabbed a heavy, leather-bound book—some dry text on clan history I'd swiped from my father's study out of spite. I stood up, feeling the plush carpet beneath my toes, and walked to the center of the room. I took a deep breath, the cold air of the penthouse filling my lungs. I threw the book into the air.
It tumbled through the space, the pages fluttering like a dying bird's wings. It reached the apex of its arc and began to fall.
"Stillframe," I muttered.
I locked my gaze on the book. I didn't just look at it; I captured it. I felt a sharp, icy spike of pain behind my right eye, and a microscopic amount of my new Cursed Energy flared.
The book stopped.
It didn't just stop moving; it stopped being part of the world's flow. It hung three feet from the floor, tilted at a forty-five-degree angle. A loose page was caught mid-flutter, bent into a stiff curve that should have been impossible. There was no vibration, no sound. It was as if someone had cut a hole in reality and pasted a photograph inside. I walked around it, my heart hammering. I reached out a finger to touch it, but I stopped inches away. I could feel the 'Absolute Containment' boundary—it felt like a wall of pressurized air, cold and unyielding. The air around the book seemed to shimmer, light refracting off the conceptual edge of the frame.
I held the focus. Ten seconds. My vision began to blur slightly at the edges. Twenty seconds. A dull ache started to throb at the base of my skull. Defiled Mind kicked in, dampening the physical pain and allowing me to analyze the strain. My optic nerves were heating up. My Cursed Energy was being sucked out in a thin, steady stream.
Thirty seconds. A thin trickle of blood escaped my left nostril. I didn't care. I was mesmerized. This was mine. Not the Kamo clan's, not the elders', not some genetic fluke I had to pray for. I had built this. I was the architect.
Forty seconds. The strain became a roar in my ears. The book began to 'stutter,' the image flickering as my focus wavered. I let go.
The book slammed into the floor with a heavy thud, the sound echoing through the room. The suppressed kinetic energy of its fall resumed instantly, making it bounce once before settling. I stumbled back onto the bed, clutching my head. My eyes were burning, and the room was spinning, but I was laughing. It was a dry, ragged sound, half-sob and half-triumph.
"Forty seconds," I gasped, wiping the blood from my lip. "Forty seconds of being a god. I'll take it."
But I couldn't stop there. The Heavenly Cycle was humming, demanding to be used. The small boost from the quest reward was sitting in my core, unrefined and restless. I sat cross-legged on the bed, forcing my shaking limbs into a lotus position. I closed my eyes and turned my attention inward.
With Stillframe Sovereignty, I had felt like a hunter. Now, with Heavenly Cycle, I felt like a gardener. I visualized the 'Cursed Energy' as a muddy, turbulent stream. Using the instincts burned into my mind by the System, I began to guide it. I pulled the energy up from my gut, through the solar plexus, and into my lungs. I 'breathed' with it, synchronizing the flow with my heartbeat.
Cycle one. The energy was jagged, full of the resentment I'd felt leaving Kyoto. I pushed it through the 'refinery' of my brain, letting Defiled Mind strip away the emotion. The energy cooled, turning from a muddy red to a pale, shimmering silver.
Cycle two. I pushed the silver energy down into my marrow. I felt my bones hum. It wasn't just energy anymore; it was becoming me. The fatigue from the Stillframe test began to recede, replaced by a deep, buzzing clarity.
Cycle three. I entered the False Zenith. The sounds of Tokyo faded. The feeling of the bed disappeared. I wasn't a twelve-year-old boy in a penthouse; I was a closed loop. I didn't need to breathe. I didn't need to eat. The world outside could end, and I would still be here, rotating, refining, growing.
I saw my future in that darkness. I didn't see myself as a hero saving people from curses, nor did I see myself as a villain burning the world down. I saw a man who was untouchable. I saw a master who could freeze the sun and drink the energy of the stars. The Kamo clan thought they had cast out a failure, but they had actually released a virus into the world—a virus that grew stronger every time it breathed.
When I finally opened my eyes, the sky outside was beginning to turn a pale, bruised purple. Dawn was coming. I felt... incredible. My Cursed Energy reserves hadn't tripled, but they were denser. The 'battery' was the same size, but it was now a high-performance lithium-ion instead of a leaky alkaline.
I stood up and walked to the floor-to-ceiling window. The first rays of sunlight were hitting the tips of the skyscrapers, turning the city into a forest of gold and glass. I looked at my reflection. I looked younger, somehow, but my eyes were ancient.
"Step one: survive," I said to the glass. "Step two: grow. Step three: make them regret letting me live."
I reached out and placed a hand on the cool window. I felt the tiny spark of the Heavenly Cycle still spinning in my chest, a permanent engine of progress. For the first time in twelve years, the weight in my chest wasn't sorrow or anger. It was anticipation.
The Kamo Arata who had walked into this penthouse yesterday was dead. He was a boy defined by what he lacked. The person standing here now was something else entirely. I was a creator. I was a cultivator. I was the glitch in the Jujutsu world's ancient, rotting system.
I looked down at the city, at the millions of people waking up to start their ordinary lives. Somewhere out there, curses were forming in the shadows of schools and hospitals. Somewhere out there, Gojo Satoru was probably eating a souvenir sweet and being the strongest. And somewhere out there, my father was probably having breakfast, thinking he'd successfully cleaned his house of a nuisance.
I smiled, and it wasn't the smile of a twelve-year-old. It was the smile of a man who had just found the cheat codes to reality.
"Enjoy your breakfast, Father," I whispered. "I'm going to enjoy the process of becoming your worst nightmare."
I turned away from the window, the sunlight catching the silver glint in my eyes. I had sixty million yen, a loyal servant in the next room, and the power to rewrite the laws of existence. The tutorial was over. Now, the real game began. I climbed back into bed, not to sleep, but to start the next cycle. Every second I spent doing nothing was a second I wasn't evolving, and I had a lot of catching up to do.
The silence of the penthouse was broken by the sound of a soft, rhythmic hum—the sound of my own soul turning into something more. It was the most beautiful thing I'd ever heard.
