A year had passed.
The seasons had turned—autumn gold to winter white to spring bloom and back again. The palace walls had not changed, but the world inside them had shifted in ways no one but Arata could see.
In two weeks, he would turn eleven time turns so fast but birthdays were secondary concerns.
--------------------------------
Six months ago, somewhere outside the capital a laboratory lay and currently it was a wreck.
Scrolls lay scattered across every surface—unrolled, half-read, stacked in precarious towers that swayed whenever someone walked too close. Clay pots held desiccated remnants of failed experiments. Chalk markings covered the stone floor, diagrams of frequency patterns and chakra matrices that had been rewritten dozens of times.
In the center of the chaos, Arata sat cross-legged on a worn cushion, his hair longer now, his face thinner. He had grown a few inches—not much, but enough that his sleeves no longer quite reached his wrists.
Before him, a row of snails sat on a wooden board.
They were larger than ordinary snails—each about the size of a fist—and their shells bore intricate markings that pulsed faintly with chakra. Their eyestalks swayed slowly, watching him with an intelligence that ordinary snails did not possess.
Arata rubbed his eyes.
six months, he thought. six months of failures! breakthroughs, and more failures.
The problem had been frequency.
Snails were naturally sensitive to vibrations. They could sense the world around them through subtle shifts in the air, the ground, the very fabric of their environment. In theory, that sensitivity could be used for communication—two snails, attuned to the same frequency, relaying sound between them.
But the snails could not produce a unique frequency of their own. Every living thing vibrated, yes—every cell, every chakra pathway, every heartbeat. But those vibrations were chaotic, unfocused, useless for the kind of precise connection Arata needed.
For six months, he had been stuck.
Then he had stumbled upon the answer almost by accident: markings.
The study of jutsu formulas—seals, arrays, inscriptions—had been a side project, something to occupy his mind during the long nights when the frequency problem refused to solve itself. He had been experimenting with a sub-copy of his snail, inscribing a marking that was supposed to stabilize chakra flow.
He had made a mistake.
The marking was wrong—a stroke misplaced, a line angled incorrectly. But instead of failing, the marking had filtered. It had taken the chaotic vibration of the snail's chakra and squeezed it into something narrow. Something unique.
A frequency.
Arata remembered the moment clearly. He had been staring at the snail for a full minute, his mind refusing to believe what his senses were telling him. Then he had laughed—a loud, startled laugh that echoed off the lab walls.
He had fused the frequency-sensing trait to himself a month ago. It was a risk—mixing summon traits with his own body—but it had worked. He could now feel the subtle frequencies of the world around him, like a new color added to his vision.
The second snail had taken another month to decode and replicate the marking. And when he had finally connected them—two snails, two unique frequencies, a bridge of chakra between them—
They had blubbered.
Arata smiled at the memory. The snails had opened their mouths and produced a stream of nonsense sounds, neither voice nor vibration but something in between. He hadn't understood a word. But the frequency line had vibrated in sync with their movements, and he had known—known—that he was on the right track.
--------------------------------
The second half of the year had been about enhancement.
While the shadow network expanded, Arata had poured himself into the snails. He had enhanced their sensing abilities, sharpening their natural frequency detection until they could distinguish between a dozen different callers at once. He had expanded their memory, increasing their capacity from the equivalent of a goldfish to that of a chunin-level ninja—enough to retain hours of conversation, enough to remember the nuances of each unique voice.
And then, unexpectedly, the snails had developed self-awareness.
It had not been intentional. Arata had simply given them too much—too much chakra, too much memory, too much sensory input. At some point, the combination had crossed a threshold. The snails had begun to think, to be curious and to react to something.
The first time a snail had asked him a question, Arata had nearly dropped it.
"Are you my owner?" the snail had said, its voice slow and watery. "Why are you staring?"
He had gotten used to it since then. The snails were not geniuses—their intelligence was simple, childlike, focused on their function. But they were aware. And that made them infinitely more useful than any mindless tool.
He had also fused a voice mimicry trait into them, borrowed from a small bird he had copied in the palace gardens. The snails could now replicate the exact tone, pitch, and cadence of any speaker whose voice they had heard. The message would arrive not as a generic recitation, but as the person's own voice.
Arata had wanted to add more features—encryption, auto-routing, visual transmission. But he had forced himself to stop. The snails were still in their initial experimental phase. Adding too many variables would increase the chance of catastrophic failure.
One step at a time, he reminded himself. Perfect the basics. Then expand.
--------------------------------
While the snails had been evolving, so had the shadow network.
The hundred shadow spies Arata had deployed across the Land of Grass had grown into a quiet army. They lurked in the corners of noble estates, the back rooms of merchant guilds, the shadows of council chambers. No information slipped through their grasp. Arata now controlled the central intelligence of the entire nation.
But the real work had been with the nobles and merchants.
Elder Mura, through his son Raizen, had spent the year carefully arranging nobles and merchants into his growing faction. He believed he was building a coalition that would support his coup when the time came. He believed these people were his instruments.
He was wrong.
Every noble and merchant who had shown interest in profiting from the coming turmoil had been quietly approached by Arata's shadows. Not all at once—that would have been noticed. One by one, patiently, they had been extracted from their homes, their carriages, their private chambers.
The process was always the same.
A shadow spy would wait until the target was alone. Then another shadow would rise from the floor, from the wall, from the darkness beneath the bed. The target would be pinned, silenced, and dragged into the headquarters space—Arata's pocket dimension, where no sound escaped and no help could come.
There, Arata would be waiting.
He had perfected the technique over the year. A palm on the forehead. Extraction of the soul and memories. Copy of the empty body. Fusion into a loyal servant. The entire process took less than five minutes.
The original body would be disposed of—dissolved by shadow, leaving no trace. The new version would return to the world wearing the same face, the same voice, the same memories. But inside, something fundamental had changed.
They were his now. Completely.
And through them, Arata had gained more than just obedient underlings. Each noble brought knowledge of their networks—trade routes, supply chains, political connections. Each merchant brought access to resources—warehouses, shipping manifests, secret accounts. Each shinobi in their employ brought jutsu.
The techniques were modest—chunin-level at best. Basic elemental manipulation. Body flicker. Replacement. Nothing that would impress the great villages.
But Arata had his Forge.
He had taken those chunin-level jutsu and fused them together, layering traits, combining elements, refining the chakra matrices. The result was a collection of B-rank techniques—powerful enough for a special jounin to use effectively. He had stored them as master copies in his infinite storage, ready to be fused into any loyal servant who needed them.
The Nara clan's shadow techniques are still out of reach, he admitted to himself. But what I have now is enough. More than enough.
His organization was already a force to be reckoned with.
And Elder Mura had no idea.
--------------------------------
The mass production had been the final stage.
One hundred sub-snails, each carrying the same core enhancements: frequency generation, memory retention, voice mimicry, and a connection to the main server snail—the original summon, now grown to the size of a small dog, its shell covered in complex markings that served as the hub for the entire network.
Every sub-snail's frequency was registered with the main server. Every call passed through it and every message was logged and recorded to a crystal ball that Arata made as a log storage.
The first information network in the Naruto world, Arata thought. And it's mine.
He had distributed the sub-snails to his subordinates two months ago. The shadow spies, the converted maids, the nobles and merchants he had subtly brought under his control—all of them now carried a snail. All of them could communicate instantly across any distance.
So far, the experiment had been flawless. No failures. No hiccups. The snails worked exactly as intended.
Arata picked up one of the sub-snails from the board. It gurgled softly, its eyestalks curling toward him.
"Almost there," he murmured. "Just a little more testing. Then we can introduce them to our neighbors first."
The snail blinked.
Far away, in the palace, Yamiko stood by the window.
The room was quiet. The futon was empty—the figure seated on it was not Arata but a copy, one of his shadow spies transformed to resemble him, left behind to maintain the illusion that the prince was still in the palace.
The real Arata was in the laboratory, somewhere outside the capital.
A palm-sized snail rested on her shoulder, its shell warm against her neck. Its eyestalks swayed gently as it faces was copying the shadow spy expression at the end of the line.
"Report from Shadow Forty-Seven," the snail said.
The voice was dull, flat—voice mimicry is activated as it matched the voice of the caller.
"Elder Take has mobilized approximately one hundred shinobi. Their objective is to solidify the defenses of the two bridges. Positions have been assigned. Rotations are being established. No unusual activity detected."
Yamiko nodded. "Continue monitoring. Report any changes."
The snail was silent for a moment. Then it made a soft sound—kacha—the signal that the transmission was complete. The connection closed.
The snail's expression shifted. Its eyestalks curled upward, and it turned to face Yamiko with what might have been interpreted as a flirtatious gaze.
"Why are you looking at me like that?" the snail asked. "Are you in love with me?"
Yamiko blinked.
The snail lifted its imaginary chin, puffing out its small body in an attempt to appear charming. "Sorry. My heart has already been captured by my love. You are beautiful, but I am taken."
Yamiko stared at it for a long moment.
Then she shook her head.
The snail had been doing this for weeks—making declarations of love, flirting with anyone who carried it, generally behaving like a tiny, shelled romantic being. No one knew why. It was simply… its personality.
Personality, Yamiko thought. They have personalities now.
She had seen how precious these creatures were. How they had revolutionized communication. Before the snails, messages had taken hours or days to travel. Now, a shadow spy on the eastern border could speak directly to a spy in the capital. Orders could be given and received in real time. Information flowed like water.
No one else has this, she thought. No village, no clan, no nation. Only Master.
She turned to the window, facing the direction where she knew the laboratory lay—somewhere beyond the capital, hidden in the hills, invisible to anyone who did not know where to look.
The snail on her shoulder settled down, its eyestalks drooping contentedly.
"Are you thinking about Master?" it asked.
Yamiko did not answer.
"I think about my love," the snail continued. "Every day. Every night. My love is far away, but I feel the connection. It is like frequency connecting me to her."
Yamiko's lips twitched—the faintest hint of a smile.
"Perhaps," she said quietly, "you should focus on your duties."
"My duties are love," the snail declared. "But I will also monitor every incoming message and call for you my dear."
The snail fell silent.
Yamiko continued to stare out the window, watching the moon rise over the capital.
