Noa POV
I woke up to Shisui shaking me gently, his voice calm but amused. "Look at you, sleeping this deeply while your team fights for their lives. We have been trying to wake you up for a while now." I pushed myself upright with a quiet groan as my body protested immediately, a deep ache spreading through my muscles while fatigue clung to me like weight in my bones. I glanced at Kaen, who was grinning with undisguised pride, and managed a weak smile in return. He nodded back, clearly pleased with himself, while Sena sighed and shook her head in that familiar, quiet way of hers.
To my surprise, Shisui was smiling, bright nonetheless. "Half of the semifinals are from one team. My first genin team ever. We are dominating this." I could not really blame him. If all my students had made it this far, I would have been proud too, even if the thought barely had time to settle before exhaustion dragged it back down again.
The walk back to the flat passed mostly in silence on my end. Kaen, on the other hand, talked nonstop, replaying the match and chewing Shisui's ear off with every detail. Sena walked a little apart from us, eyes drifting across the streets and rooftops, always intrigued by the Hidden Sand's architecture and atmosphere. Once we reached the flat, I barely made it to the bed before collapsing, the world fading out almost instantly.
I slept for nearly twelve hours. When I finally woke, my head felt light and my limbs heavy, as if my body was still catching up with itself. A long shower helped loosen the stiffness, and I forced myself through a proper meal afterward, making sure to get protein, salt, and enough water back into my system. No shortcuts. Recovery was not glamorous, but skipping it would only make everything worse.
Only after that did I walk back into my room with slow, heavy steps and approach Master Shuzo's scroll. When I tried to touch it, my hand stopped. The image of him surfaced in my mind, sitting in the hidden compartment of the library with complete focus, the world fading around him whenever he worked. He had been happiest while writing seals, truly alive in those moments. I found myself reliving a specific memory, a time when I had been duplicating the same seal for the hundredth time as punishment while he worked on one of the village's barrier seals, as he always did. I remembered how he had stopped mid-stroke, looked over at me, and instead of being angry that I was slacking, he had simply smiled, his aged face lighting up.
My throat tightened as I pushed the feeling down, blinking until the blur faded from my vision. I took a deep breath, closed my eyes, and steadied my hand before gripping the scroll. This scroll was not just knowledge. It was his life's work, his legacy, and his final gift to me.
I unrolled it and, with a quick hand sign, summoned my own notes on Gaara's seal into view, forcing my focus back to escape the pain and tightness in my chest.
After a couple of deep breaths to regulate my emotions, I turned my thoughts back to Gaara's seal. At its core, a jinchuriki seal exists to perform one fundamental task, to restrain a natural disaster inside a human vessel and prevent it from fully manifesting. Everything beyond that is refinement layered on through advanced fuinjutsu. The Hidden Sand's seal reflected a more direct philosophy, prioritizing containment over harmony, a singular focus on function over long-term stability.
That was not surprising. Suna had never been known for elegance in their jinchuriki work, and improving a seal of that complexity required generations of accumulated expertise. Expertise they simply did not have. Konoha did, inherited through the Uzumaki clan, the finest seal masters the shinobi world had ever produced. They had been feared for that knowledge, feared enough to be annihilated, yet fragments of their techniques lived on. I frowned, trying for the life of me to remember the name of the First Hokage's wife, but it refused to come. Another Uzumaki surfaced instead. Kushina.
I did not have a complete image of Gaara's seal, but I did not need one. By breaking it down by function, by understanding what it was meant to do rather than how it was drawn, I was already closing in on a full reconstruction. The One-Tail's seal was not especially advanced compared to Konoha's standards, but it was still a jinchuriki seal. There was no such thing as an easy one.
That realization settled my decision. For the next week, this would be my sole focus, paired with recovery. No ninjutsu drills, no taijutsu conditioning, no kenjutsu practice.
Instead, I committed to careful rehabilitation, light stretching in the mornings to restore mobility, slow walks to keep circulation moving, and controlled breathing to stabilize my chakra flow. I kept my meals regular, tracked my hydration deliberately, and treated sleep like a requirement instead of a luxury. Between those routines, hour by hour, I worked exclusively on the seal, refining my deductions while my body rebuilt itself. I did not have the luxury of taking my time, and if I wanted to keep my friends and loved ones safe and survive what was coming, then I needed to go all out with a singular focus, using everything I had to get this done.
I ran into a problem almost immediately. There was a missing seal, one designed to regulate enormous amounts of chakra so it would not flood the system and tear everything apart in its path. The scroll did contain such a seal with that exact function, one used in the barrier that surrounds the village, but it was far too advanced for me. I could not draw it, replicate it, or even fully map its internal logic yet, and forcing my way through it would only waste time. That meant I had to approach the problem differently.
What I understood was straightforward. A standard chakra flow regulation seal smooths circulation and prevents irregularities in chakra flow, working well enough within normal human limits. Against jinchuriki chakra, it would fail almost instantly. That kind of chakra was dense, violent, and explosive, not just in quantity but in behavior, and forcing all of it through a single regulation point was no different from trying to drain a flood through a narrow pipe. The system would not fail gracefully. The host would fail explosively.
That realization shifted my thinking away from raw strength and toward scale. Instead of trying to recreate one extremely powerful and overly complicated regulation seal, I focused on distributing the load. I took a simple flow regulation seal, something I understood completely, and paired it with a duplication seal, reinforcing the entire array with a strengthening seal layered around it.
Normally, duplication seals are used in large-scale traps to replicate simple seal arrays across wide areas, saving time and effort instead of drawing the same seal repeatedly. They are inflexible by nature and collapse if different sections require different logic, but that weakness did not matter here because every regulation point would perform the exact same function.
It would be one narrow channel, duplicated again and again until it matched the incoming flow. It was not elegant, and it was certainly not professional, but it was functional. Rather than choking the chakra through a single point, the duplicated seals created a network of parallel paths, each one handling only a fraction of the load. Pressure was bled off gradually instead of violently, absorbed across the system instead of concentrated at its core. The seal no longer relied on a single point of failure.
It was a workaround rather than a masterpiece, but it achieved the same result without requiring full mastery of the original design, and for now, that was enough.
This was not the final answer, only a bridge. To truly improve Gaara's seal, I would need the complete image, the full structure laid bare so I could understand not just how it worked, but why it had been built that way. Until then, my priority was knowledge. I spent every spare moment studying sealing theory, expanding my foundation so that when I reached that point, I would not be guessing blindly. Sena and Shisui noticed that I had stopped training my jutsu and were concerned at first, but once they saw that I kept eating properly, drinking enough, and exercising regularly to maintain my condition, they trusted my judgment and let it go.
The day before the next match arrived faster than I expected, and I found myself breaking my own promise and pulling an all-nighter, exhaustion held at bay by how close I was to the answer. Sleep felt impossible with the solution just out of reach. In my hand was a single sheet of paper containing the last unidentified function, now translated into a complete seal formula. I stared at the wall in front of me, covered in notes, diagrams, and differently colored cloth threads connecting separate concepts together, and stepped forward slowly as I placed the final piece into position.
I backed away until my back touched the opposite wall, breath shallow as the full structure resolved itself in front of me. The shape that emerged resembled a massive, swirling spiral.
Down at the center was the base function, the act of sealing a physical entity into a human. Simple enough in concept, though sealing something that powerful was anything but easy.
Above it was a seal array that regulated the base seal, taking the load of the tailed beast pushing back and functioning like shock-absorbing springs. The pressure was redirected rather than resisted outright, preventing the structure from tearing itself apart under constant strain.
That excess energy was pushed upward, where a different seal layer captured it and used it to strengthen the structure itself, like a dam using the water flowing through it to generate energy. That same layer fed the generated force back down, reinforcing the first sealing layer. I chuckled softly as the realization settled in. The tailed beasts were basically powering up their own prison by fighting back.
Above that sat yet another layer designed to shield the host from the effects of the tailed beast's negative emotions, filtering the chakra backlash before it could bleed into the host's mind and body.
The final layer converted what remained into neutral output, allowing it to integrate naturally into the jinchuriki system, improving their chakra reserves to those incredible levels that only they possessed.
I started laughing before I even realized it. I was not trying to. It just slipped out. It was beautiful. Every layer served a separate function, yet they were all connected, relying on one another, arranged in a way that spoke of the absolute genius of those who had designed it. I could not stop laughing, my body shaking from excitement, from the rush of figuring something this massive out, and from sheer exhaustion all at once.
My understanding of fuinjutsu was transforming right then and there. My eyes stayed locked on the seals as the laughter continued, my thoughts shifting and rearranging themselves, my mind almost rewiring itself as it adapted to this new understanding.
Concepts that had once felt distant and unreachable began to clear, finally starting to make sense as I tilted my head and looked at the seals again, as if I were seeing them for the first time, not with new eyes, but with a new understanding.
