The reflection stared back at me, and the wheel stared with it.
I remained crouched at the river's edge, my fingers still extended toward the rippling image of a ghostly halo that hadn't been there when I'd fallen asleep. The eight-spoked wheel rotated slowly behind my head, its golden spokes catching the last light of the dying sun, the spheres at their tips pulsing in a rhythm I could feel in my chest like a second heartbeat. It was beautiful.
Intangible.
My hand had passed through it three times now, each attempt confirming what the first had suggested. The wheel was not made of matter. It cast no shadow on the water, disturbed no air when it turned, made no sound as its spokes traced their eternal circle. It was a manifestation of spirit, of the Talent, of the adaptation engine that had been churning inside my soul since the moment I'd woken up in a dead boy's body five years ago. The grimoire's integration had dragged it into the visible spectrum, but it remained as untouchable as a thought.
I rose to my feet, my grey eyes still fixed on the reflection. The wheel followed the movement seamlessly, maintaining its position behind and slightly above my head like a crown I hadn't asked for. The panic that had seized me moments ago—not panic, the locks wouldn't allow panic, but the cold echo of it, the physiological startle response of a predator whose camouflage had been breached—was already fading, replaced by the familiar machinery of tactical analysis.
Could others see it? The question surfaced and was immediately filed under "pending data." I had no way to test that hypothesis without exposing myself to an observer, and exposing myself without sufficient data was inefficient. For now, I would assume the wheel was visible. That assumption created vulnerabilities. Vulnerabilities required mitigation.
The Binding Vow.
The first page of my grimoire had outlined the principle: sacrifice a limitation, gain power. Revealing one's abilities to an opponent was listed as a viable self-imposed vow, yielding a twenty percent increase in spell effectiveness. If the wheel was visible, it was already revealed. I couldn't hide it—so I would weaponize its visibility. Every enemy who saw the wheel would know that I was something other than human. That knowledge, in the framework of a Binding Vow, could be converted into raw power. The vow would be simple: "I reveal the existence of the Wheel of Adaptation to my opponent. In exchange, all my magical parameters increase by a fixed percentage for the duration of the battle." The percentage would depend on how much of a disadvantage the revelation created. The greater the disadvantage, the greater the reward.
And if the wheel was not visible to others? Then I could choose to reveal it, triggering the vow voluntarily. Either way, the wheel's manifestation was not a weakness. It was an opportunity. A lever I could pull to trade information for power.
The cold void where my emotions had been sealed registered a flicker of something almost like satisfaction.
Permanent self-imposed vows are also possible, I noted, my mind already spinning through the possibilities. I could sacrifice my ability to feel pain—already functionally gone, thanks to Pain Resistance (Highest)—and gain a permanent amplification of my physical durability. I could limit my mana output to a single element in exchange for a dramatic increase in that element's potency. I could stake my life on a condition, as the grimoire had suggested, and unlock sealed techniques that would otherwise remain beyond my reach. The Binding Vow system was a second engine of growth, parallel to the Talent, and I had only scratched its surface.
But theory was for later. For now, training.
I turned away from the river, the wheel's golden light painting faint highlights on the leaves behind me, and walked back toward the cave. Tonight, I would begin the sleep adaptation. Tomorrow, I would push my body and mana to their limits. And within a few months, I would emerge from this jungle as something that even the captains of the Magic Knights would hesitate to challenge.

The Sword of Severance hummed in my right arm as I walked, a constant presence that I'd grown accustomed to over the past weeks. I flexed my will, and the blade emerged—a length of pale, gleaming bone that extended from my forearm like a natural extension of my skeleton. It was physical, as physical as my own ribs, but it shared the Soul Slash property that made it pass through material objects as if they were mist. I'd tested this extensively: the blade could not cut wood, stone, or flesh. It passed through armor, shields, and magical barriers without resistance. What it cut was the soul. And when it cut, the target's consciousness was severed from its body, leaving behind an empty shell.
I ran my left hand along the blade's edge. My fingers passed through it, feeling nothing but a faint chill, like the memory of cold water. It was a paradox—a physical object that behaved like an immaterial one, a sword that could be seen but not touched, a weapon that existed in two realms simultaneously. The grimoire called it the Sword of Severance. My past-life memories called it the Sword of Extermination. Both names were accurate. It exterminated souls. It severed them from their anchors. And it was mine.
I retracted the blade, feeling it slide back into the sheath of my radius and ulna with a sensation that had become almost pleasant in its familiarity. The wheel continued to turn behind my head. The grimoire floated at my waist. I was a walking arsenal, and I hadn't even started the real training yet.
---
The sleep adaptation began that night.
I did not sleep. I sat in the cave, my back against the cold stone, and waited for the exhaustion to build. The first day was easy. I'd gone three days without sleep before, and my body was conditioned to endure far worse. The second day was harder—my eyelids grew heavy, my thoughts slowed, and my mana pathways began to flicker with the erratic pulses of a brain that was being denied its reset cycle. I ignored the signals. Pain Resistance (Highest) muted the headache. Emotional Nullification muted the frustration. I was a machine, and machines did not need rest.
The third day was when the damage began.
Sleep deprivation, I learned, was not a single phenomenon. It was a cascade. First came the cognitive decline—slower reaction times, impaired judgment, difficulty focusing. Then the physical symptoms—muscle weakness, tremors, blurred vision. Then the hallucinations. I saw things that weren't there: shadows moving in the corners of the cave, voices whispering in the rush of the waterfall, the faces of the dead flickering at the edges of my vision. Father Aldric. Sister Maria. Elise. They stared at me with empty eyes, and I stared back with equally empty ones, and neither of us felt anything.
The hallucinations were data. The cognitive decline was data. The physical breakdown was data. The Talent catalogued it all, turning its invisible wheel in the depths of my soul, analyzing the phenomenon of sleep deprivation and building a countermeasure. I could feel it working, a subtle pressure in my chest, a warmth that had nothing to do with temperature. The locks were preparing to engage. But the process was slow—slower than I'd expected. Sleep was not a simple stimulus like fire or water. It was a fundamental biological process, woven into the fabric of consciousness itself. Adapting to its absence would require more than a single push.
So I pushed harder.
On the fourth day, I forced myself to train. Push-ups with boulders on my back. Mana Skin Full Release sustained for hours. Soul Slash practice against the empty bodies of mana beasts I'd killed earlier. The exertion amplified the damage, and the damage amplified the adaptation. I could feel the first clunk approaching, a pressure building at the base of my skull like a storm waiting to break.
It broke on the fifth day.
CLUNK__
The sound resonated through my skull, and a wave of clarity washed over me. The brain fog lifted—not entirely, but noticeably. My thoughts sharpened. My vision steadied. The hallucinations retreated to the edges of my perception, still present but no longer intrusive. The first lock had engaged. Basic resistance to sleep deprivation.
I kept going.
Each lock brought a new level of clarity, a new reduction in the damage sleep deprivation could inflict. By the end of the first month, I was functioning at near-peak efficiency despite not having closed my eyes for thirty consecutive days. The hallucinations had vanished entirely. The cognitive decline had reversed. My mana pathways, which had been flickering with exhaustion, now hummed with steady, sustainable power. My body had learned to enter a state of micro-rest while still conscious, cycling through brief moments of neural recovery that replaced the need for full unconsciousness. I didn't sleep. I didn't need to sleep. The biological drive had been analyzed, adapted to, and nullified.
—the final lock, the threshold of true immunity—came on the forty-second.
CLUNK__
And then there was silence. The deep, resonant silence of absolute adaptation. I sat in the cave, my grey eyes wide and clear, and felt the last traces of exhaustion drain from my body like water from a cracked vessel. I was no longer capable of sleep. It was not a choice; it was a state of being. My consciousness would remain unbroken for as long as I existed. The wheel had turned. The locks had engaged. Sleep was just another phenomenon I had conquered.
I rose from my meditation seat and walked out into the jungle, the wheel behind my head casting its golden glow on the leaves. The sun was setting. I had been awake for forty-two days. I felt more alert, more present, more powerful than I ever had before.
The month of torture had been worth it.
---
The remaining months blurred into a rhythm of relentless improvement.
With sleep no longer consuming a third of my time, I had sixteen extra hours each day to train. The efficiency gains were staggering. What had taken me a year to achieve before could now be compressed into a matter of months. The wheel—now visible, now turning, now a constant companion—seemed to respond to this new reality with increased enthusiasm. Its rotations were smoother, faster, the golden spheres at its spoke-tips blazing with light whenever the Talent activated. I noticed, after a few weeks of careful observation, that the adaptation process had accelerated. Resistances that had taken days to build now took hours. Mana recovery that had required hours of rest now happened in minutes. The wheel's manifestation had not just been cosmetic; it was a signal that the Talent had evolved, its connection to my soul deepened by the grimoire's integration.
I pushed every limit I could find.
Mana Stage I had been a distant goal before the sleep adaptation. Now, with twenty-four hours a day to devote to training, it became inevitable. I drained my reserves completely, again and again, cycling through Mana Skin, Reinforcement Magic, and the basic water spells I'd refined over the past year. Each cycle expanded my capacity by a fraction of a percent. Each fraction accumulated. By the end of the second month, the shimmering barrier I'd sensed at the edge of Stage II cracked, then shattered, and mana flooded into me with the force of a breaking dam. Stage I. The mana of captains. The mana of royalty. The mana of legends in the making.
Control was a struggle—Stage I mana was denser, more volatile, more alive than anything I'd handled before—but the Talent did what it always did. It adapted. Within a week, I could channel my new reserves with the same precision I'd had at Stage III, then Stage II, then beyond. The wheel turned. The locks engaged. The power settled.
Physical conditioning reached inhuman extremes.
I had long ago exhausted the jungle's supply of boulders heavy enough to challenge me. I improvised. I uprooted entire trees and used them for resistance. I wrestled the largest mana beasts I could find, grappling creatures that weighed thousands of pounds and winning through sheer physical dominance. I ran sprints through the densest undergrowth, pushing my speed until the trees blurred and the wind screamed in my ears. I stretched my body to its limits and then beyond, working my flexibility until I could bend in ways that defied human anatomy—joints dislocating and relocating at will, spine curving like a serpent, limbs twisting into positions that would have broken a normal person's bones. I remembered, from the fragments of my past life, a loud demon slayer with a boar's head who could bend his body like rubber, and I made him my benchmark. Within three months, I could match and exceed that flexibility, my body a weapon that could attack from any angle, evade any blow, contort through any gap.
Endurance became infinite in practical terms. Vascular Regulation, now enhanced by Stage I mana and the sleep adaptation, kept my muscles oxygenated and my energy reserves perpetually topped off. I could fight at maximum intensity for days without slowing. Stamina was no longer a resource I needed to manage; it was a constant, like breathing, like the turning of the wheel.
The black market bombs were an impulse purchase during a supply run to a nearby city. I'd gone to trade beast pelts for training equipment—weights, blades, anything I couldn't craft in the jungle—and I'd stumbled upon a merchant selling alchemical explosives. The kind of bombs that could level a building. The kind of force that could push my regeneration past its current ceiling.
I bought thirty of them.
The testing ground was a remote valley three miles from my cave, a barren depression in the earth where I could cause destruction without attracting attention. I stripped off my clothes—they were a pain to replace—and stood at the center of the valley with the first bomb in my hand. The wheel turned behind my head, golden and patient, waiting for the phenomenon to begin.
I detonated the bomb against my own chest.
The explosion was a sun, a roar, a wave of heat and pressure that turned my torso into a crater of shredded meat and shattered bone. My body flew backward, slammed into the valley wall, and crumpled to the ground in a heap of pulverized flesh. By any rational measure, I was dead. My heart had been vaporized. My lungs were gone. My spine was visible through the ruin of my chest cavity.
Then the regeneration kicked in.
High-Mid tier was different from what I'd had before. The Low-Mid tier had let me regenerate limbs and survive being sliced in half. High-Mid tier let me regenerate from a single surviving piece—a finger, a heart, a fragment of brain. The bomb had reduced my torso to a crater, but my head and limbs were mostly intact. That was enough. The flesh began to knit, crawling back into place with a speed that would have been horrifying to anyone capable of horror. Bone re-formed. Muscle re-wove. Skin stretched across the wounds and sealed. Within three minutes, I was whole again, standing in the crater of my own creation, my skin unblemished and my expression utterly blank.
I picked up the second bomb.
I detonated twenty-seven bombs that day, each one destroying a different part of my body, each one pushing my regeneration to work faster, more efficiently, more completely. The Talent catalogued every explosion, every pattern of damage, every cellular reconstruction sequence. The wheel FINALLY turned and by the time the last bomb's echoes faded into the valley, my regeneration had evolved. High-Mid tier was now fully mastered. I could regenerate from a single surviving piece of my body—a severed finger, a chunk of flesh, a drop of blood that still carried my mana signature. The next tier, Low-High, would let me regenerate from a puddle of liquid or a single cell. I wasn't there yet, but the path was clear.
Kinetic Redirection, the final Advanced Reinforcement technique, remained stubbornly out of reach. I understood the principle: absorb the momentum of an incoming strike and channel it into a counter-attack. But the technique required an opponent. A real opponent, with real killing intent, who could deliver attacks powerful enough to force my body to learn. The jungle's mana beasts weren't enough. The bombs were too indiscriminate. I needed a fight. A real fight. The Magic Knights Entrance Exam was the answer. Somewhere in that arena, I would find an opponent who could push me to the edge. And when I did, the Talent would do what it always did. It would learn. It would adapt. It would overcome.
---
The morning of my departure arrived without ceremony.
I stood at the mouth of my cave, the waterfall thundering its endless song behind me, and summoned the status screen for one final review. The grimoire's integration had completed three months ago, and the screen had emerged from its upgrade with a new, stylized interface that I had to admit was aesthetically impressive. The cold machinery of my mind did not feel pride, but it could recognize functional elegance, and the new design was undeniably elegant.

I read through the matrix with the clinical detachment of an auditor reviewing a balance sheet. Soul Damage Immunity and Emotional Nullification remained unchanged, the two foundational pillars of my existence. Piercing, Cutting, Water, Fire, and Fall resistances had all stabilized at Mid-tier, waiting for the extreme stimuli that would push them to High and then Immunity. Blunt Force was still Low, a reminder that I needed heavier impacts, stronger enemies, more devastating force.
The abilities were solid. High-Mid Regeneration. Soul Slash. Mana Pressure now extended a full hundred meters, its density enough to crush the will of anyone below Stage III. Mana Skin and Full Release. Reinforcement Magic at Advanced, with Mana Skin Integration and Total Concentration mastered. Underwater Breathing, still useful, still functional.
Kinetic Redirection was absent from the list. A blank space where a technique should be. A reminder that I had reached the limits of what solitary training could achieve. The jungle had given me everything it had to offer. To grow further, I needed the world.
I closed the screen and looked out at the horizon. The capital lay somewhere beyond the mountains, a city of white stone and floating squad headquarters and an exam that would determine the trajectory of my future. Asta and Yuno would be there, the short loud one and the quiet prodigy, chasing their dreams with an intensity that I could recognize even if I could no longer feel. Yami Sukehiro would be there, the captain of the Black Bulls, the master of ki and Mana Zone, the man whose techniques I needed to learn. And somewhere beyond all of that, the Midnight of the Evil Eye was still breathing. That was a phenomenon I intended to correct.
I turned away from the cave, away from the waterfall, away from the jungle that had been my crucible for over a year. My bare feet found the familiar path one last time, and then I left it behind, cutting through the undergrowth in a straight line toward the distant mountains. I didn't look back. Looking back was a behavior driven by sentiment, and sentiment had been locked away in a box of clunks and cold steel.
I ran.
Stage I mana surged through my reinforced legs, and the world blurred. Trees became streaks of green. Rivers became momentary splashes of silver. I covered ground at a speed that would have been impossible a year ago, my body a projectile launched toward the future with the wheel blazing golden behind my head. The eight spokes turned in their eternal cycle, and I turned with them, a creature of adaptation and severance, a hollow god in a fifteen-year-old body, hurtling toward the capital at full velocity.
The exam was waiting. The story was waiting. And Hasegawa Ouga, the boy who had died twice and slept no more, was finally ready to carve his name into it.
