Naruto stood in the snow for a long moment, watching the Hyuga father and daughter walk away. He did not move until their figures vanished around the corner at the end of the street. Only then did he turn and head back toward the apartment building where he lived alone, all the way up on the top floor.
As soon as he slid the key into the lock and pushed the door open, a familiar, slightly chilly stillness drifted out to meet him. The room was small, plain, and sparsely furnished. It was not spotless, but everything inside had been kept in order, enough to preserve the bare minimum of dignity a place needed before it could be called a home.
Very few people came and went here with any regularity. Other than Naruto himself, the only visitors were the ANBU assigned to monitor him in shifts. They watched, reported, and disappeared again like shadows. They never slept in the apartment, and they never stayed long enough to leave behind any warmth.
As for the Third Hokage, he only came once in a while, usually under cover of night. Wearing his robes, he would personally bring the living expenses for the next month, ask a few gentle questions about Naruto's recent days, and offer a handful of encouraging words. To Naruto, those brief meetings felt less like an elder checking in on a child and more like a routine inspection of a carefully observed test subject.
He closed the door behind him, shutting out the wind, the snow, and the noise of the world beyond it. Silence settled over the apartment at once. In the stillness, even his own breathing sounded clear.
He walked over to the little refrigerator, opened it, and found the same familiar contents inside: a few bottles of milk and several simple ingredients arranged neatly on the shelves. He took out a bottle of iced milk, pried the cap off with practiced ease, and tipped his head back for a long drink. By the time he set the empty bottle in the sink, he had already turned and headed straight for the bedroom.
Naruto sat cross-legged on the bed, which was no softer than usual, and slowly closed his eyes. His hands rested naturally on his knees as his breathing lengthened and evened out. Since arriving in this world, precise chakra control had always been one of the core pillars of his training.
He understood the future too clearly to allow himself the luxury of complacency. The enemies waiting ahead were monsters in every sense of the word. If he relied on raw reserves alone, no matter how vast those reserves might be, he would still be crushed.
For him, this peaceful childhood was only temporary. In less than ten years, the Akatsuki would begin hunting him in earnest for the Nine-Tails sealed inside him. Black Zetsu, the most devoted and twisted son of the Otsutsuki line, would keep pushing the plan to revive Kaguya. Obito Uchiha lurked in the dark, weaving the Eye of the Moon Plan into reality. And somewhere beyond all of that, Madara Uchiha waited for the day he would return from the land of the dead.
As his awareness sank inward, Naruto could clearly sense the warm, living current of chakra moving through his meridians like the first light of dawn. He did not refine it in large waves. Instead, he narrowed all of his attention to the tips of his fingers.
Under the guidance of his will, a threadlike strand of chakra was carefully peeled away from the rest. It was so fine it almost seemed imaginary, like an invisible filament stretched across empty air. He guided it with painstaking care, trying to maintain a stable shape at his fingertip, or make it pulse and flicker like breathing fire that refused to go out.
The process was tedious and draining. One slip in concentration, one moment of impatience, and that fragile strand would scatter instantly out of control. Yet Naruto's face remained intent and serious, and before long, a sheen of fine sweat had formed across his brow.
He knew this kind of practice was boring. He also knew it was unavoidable. If he wanted to stand at the top of this world one day, then this was the foundation he could not afford to skip.
As an Uzumaki, and as the jinchuriki of the Nine-Tails, Naruto possessed far more chakra than ordinary shinobi ever could. That enormous gift was also a burden. Power without control was just waste, and waste would get him killed long before destiny had finished lining up all the monsters waiting in the dark.
When he finally ended the session, the exhaustion in his mind far outweighed the fatigue in his body. Naruto exhaled slowly, then leaned back and fell onto the stiff little bed. He did not go to sleep right away. Instead, he closed his eyes and let his consciousness continue sinking, as if he were diving beneath the surface of deep water.
***
The familiar outline of his room blurred and rippled, vanishing like an image disturbed on the surface of a lake. In its place came darkness, dampness, and a strange, oppressive stillness. Shallow water spread beneath his feet, its surface trembling with eerie ripples, while the heavy air around him carried an ancient, violent pressure that pressed against the skin.
The most striking thing in that cavernous space was the massive cage ahead of him, built from row after row of thick iron bars. It loomed like a prison meant to hold a god or a calamity. Behind those bars, deep within the darkness, two enormous scarlet eyes opened first, like giant lanterns igniting in the void, their pupils narrow and beastlike.
Then the rest of the figure emerged. An enormous fox with orange-red fur lay inside the cage, seemingly at ease, yet its mere presence was enough to suffocate the air around it. Its fangs gleamed in the gloom, and the great tails behind it swayed slowly in the cramped space like burning shadows.
The Nine-Tails stared down at Naruto, who looked absurdly small by comparison, and its deep, resonant voice rolled through the sealed chamber. "You're here, Naruto."
"Yeah, I'm here, Kurama," Naruto replied, as naturally as if he were greeting an old friend.
He strode forward without hesitation until he stood right in front of the enormous iron gate. There was no fear in him. No shrinking. No attempt to disguise the familiarity in his tone.
The friendship between them had begun in a way stranger than almost anything else in Naruto's life. Not long after his soul had arrived in this body, his already mature consciousness had taken the initiative to descend into this sealed space for the first time. Back then, his physical form had still been that of an infant, but within the mindscape, his awareness had moved with complete freedom.
He had staggered right up to the gigantic cage, ignoring the murderous hatred pouring off the beast in waves so tangible they seemed capable of tearing flesh apart. Then, looking up into those furious scarlet eyes, he had spoken a name that had been buried for a thousand years. "Kurama."
That one word had stunned the giant fox into rare silence. It had been like driving a key into an ancient lock. And before Kurama could fully recover, that infant soul had gone on, calm and steady in a way completely at odds with his appearance.
"I know who you are. I know about the Sage of Six Paths too. So tell me, if I said I was the child of change and peace that he foresaw before his death... would you believe me?"
That outrageous declaration had become the beginning of countless conversations over the years that followed. Day after day, Naruto entered this space to talk with Kurama. Their relationship was not exactly warm or affectionate, but it had settled into something unexpectedly stable. A human host and a tailed beast sharing a prison, a body, and, little by little, a strange kind of understanding.
Kurama lowered its huge head slightly, its crimson vertical pupils fixed on Naruto outside the bars. Its tone still carried its usual laziness and faint impatience, but the subtle twitch at the tip of one tail betrayed what it really felt. "You always manage to bring a new subject every day. So? What is it this time?"
The truth was easy to see. Sealed in this dark, changeless space for decade after decade, staring at the same walls, the same bars, the same shallow water, even a tailed beast could be driven mad by boredom. Naruto's routine visits over the years, and the wild, borderline outrageous topics he insisted on discussing, had become the only real novelty in Kurama's endless sentence.
Naruto sat down cross-legged in front of the gate and rested his chin on one hand. He looked as though he had been thinking seriously about the issue for a while. Then he raised his head and asked in a calm, deliberate voice, like a scholar presenting a thesis instead of a child talking to a legendary beast:
"Kurama, do you think it's possible that Wood Release isn't a Kekkei Genkai at all... but a Kekkei Tota?"
The words crashed into the sealed space like a thunderbolt.
For a moment, the stagnant darkness seemed to tremble. It was as if someone had hurled a mountain into still water, sending invisible shockwaves racing in every direction. Even in a place as dead and still as this, that single question carried enough force to stir a storm.
Kurama shot upright inside the cage. Its fur bristled. Hot breath burst from its jaws in a harsh gust that rippled the shallow water under Naruto's feet.
If he was going to bring up something like that, then fine.
Kurama wasn't sleepy anymore.
