The morning sun over Konohagakure was a lie.
To the hundreds of families gathered at the Academy entrance, it was the dawn of a glorious path—the "Will of Fire" made manifest in the next generation of shinobi. But to Ryota, standing at the back of the crowd with his hands tucked into the pockets of his plain civilian trousers, the sun was merely a localized nuclear fusion reaction, and the village was a beautiful, precarious house of cards waiting for a breeze to knock it down.
I am six years old, Ryota thought, his mind humming with a frequency that would have made a seasoned Nara's head ache. And in roughly seven years, this street will be a crater. In ten, the moon will become an eye. My survival probability if I follow the 'Standard Path' is 0.003%.
He wasn't panicked. Panic was an inefficiency of the amygdala, a biological "bug" he had already begun to suppress.

The "System" wasn't a voice in his head. It was more like a command prompt at the edge of his consciousness, a legacy of his transmigration. It didn't give him free power. It gave him the math for power. It was all-powerful in its potential, but it was currently tethered to a body that got winded after a three-mile jog.
"Hey! Watch it, kid!" a man barked, nearly stepping on Ryota as he tried to get a better view of the Hokage on the podium.
Ryota looked up. The man was a Chunin, judging by the vest. Ryota didn't scowl. He didn't look afraid. He tilted his head, his dark eyes scanning the man's posture, the slight tremor in his right calf, and the way his chakra flickered like a dying candle.
"My apologies, sir," Ryota said, his voice smooth and unnervingly calm for a child. "You seem to have a slight meridians blockage in your lower leg—likely an old injury from a D-rank mission involving water-walking. You should shift your weight to the left to avoid a cramp during the Hokage's speech."
The Chunin froze, looking down at the small, black-haired boy. "What did you—?"
But Ryota had already turned away. He didn't care about the man's reaction. He had just confirmed his first hypothesis: his [Aizen-level Intellect] allowed him to perform diagnostic scans on the world using nothing but observation and logic.
The Trial of the Void
As Sarutobi Hiruzen, the Third Hokage, began his speech about the "Will of Fire," Ryota felt a sharp sting behind his eyes.

[FAILURE: PERMANENT NERVOUS SYSTEM DAMAGE.]
Bold, Ryota thought, a small, dangerous smile playing on his lips. The system wants me to hack my own biology in the middle of a crowd. Very well.
He sat down on a nearby bench, closing his eyes. To any onlooker, he looked like a bored child falling asleep during a long speech. In reality, he was entering a battlefield.
Inside his mind, Ryota saw his body not as flesh and bone, but as a complex circuit board. Most people awakened chakra through a "spark"—a teacher pushing their own chakra into the student. Ryota found that crude. He began to use his sheer force of will to pull the physical energy from his cells and the spiritual energy from his massive intellect, grinding them together at the base of his spine.
It felt like molten lead was being poured into his veins.
Focus, he commanded himself. If Aizen could stand in the heavens, I can at least sit on this bench.
He began to "code" his chakra. Instead of letting it flow wildly, he forced it into a fractal pattern—a much more efficient geometry than the standard circular flow taught in the Academy.
[CHAKRA INTEGRATION: 40%... 60%...]
His body began to sweat. His heart rate spiked to 160 beats per minute. A civilian child would have gone into cardiac arrest, but Ryota used his mind to manually override his heart's rhythm, forcing it to stay steady. He was playing his own body like a grand piano.
The First Connection
"Are you okay?"
The voice broke through the white noise of his internal struggle. It was soft, hesitant, and laced with genuine concern.
Ryota didn't break his meditation immediately. He finished the final loop of the chakra coil, "locking" the fractal pattern into place. Then, he opened his eyes.
Standing before him was a girl with pale, lavender eyes and short, dark hair. Hinata Hyuga.
Next to her, looking bored but curious, was a boy with a pineapple ponytail—Shikamaru Nara.
"You're shaking," Hinata said, reaching out a hand but pulling it back shyly.
Ryota took a deep breath. His skin felt electrified. He looked at his hands—they were steady now. He looked up at Hinata and smiled. It wasn't the fake smile of a manipulator, but the genuine look of someone who appreciated a rare variable.
"I'm fine," Ryota said, his voice returning to its melodic tone. "Just practicing a breathing exercise. It's a bit overwhelming, isn't it? All this talk of 'Fire' when the sun is already doing a good enough job of burning us."
Shikamaru let out a short, surprised huff of a laugh. "Tell me about it. Troublesome, right? I'm Shikamaru. This is Hinata."
"Ryota," the MC replied, standing up. He felt... different. Every cell in his body felt "awake."

[EFFECT: PASSIVE RECOVERY OF STAMINA +50%. MANUAL OVERRIDE OF AUTONOMIC FUNCTIONS UNLOCKED.]
"Ryota, huh?" Shikamaru squinted at him. The Nara's high IQ was sensing something "off" about the boy, but he couldn't put his finger on it. Ryota didn't feel like a kid. He felt like a storm disguised as a puddle. "You're a civilian, right? I haven't seen you at the clan gatherings."
"I am," Ryota said, brushing the dust off his pants. "Just a boy with no name and a very long 'To-Do' list. Do you think the Hokage is almost done? I'd like to get inside. The library is much more interesting than the podium."
Hinata blinked. "You... you like the library?"
"Information is the only currency that doesn't devalue," Ryota said, looking her in the eye. He saw the flicker of "The Caged Bird" in her spirit—the crushing weight of the Hyuga expectations. "Though, I suppose for some, information is a cage. For me, it's the key."
Hinata didn't fully understand, but she felt a strange sense of safety around Ryota. He didn't look at her with the pity of the villagers or the coldness of her father. He looked at her like she was a puzzle he was interested in solving.
The Mastermind's First Move
As the crowd began to move toward the Academy doors, Ryota saw him.
Naruto Uzumaki stood alone, perched on a fence, his goggles pushed up, watching the happy families with a look of profound, aching loneliness.
Ryota's mind immediately began to run simulations.
Target: The Jinchuriki. Status: Social Pariah. Strategic Value: Infinite.
But as he looked at Naruto, Ryota felt a twinge in his own chest—a remnant of his civilian humanity. He remembered what it was like to be the "other."
"Hey," Ryota called out, walking toward the fence.
Shikamaru and Hinata followed, curious.
Naruto looked down, startled. "What? You talking to me?"
"You look like you're planning a prank," Ryota said, stopping in front of the blonde boy. "But your stance is wrong. You're leaning too far to the right. If you jump from there to the Academy roof, you'll slip."
Naruto's eyes widened. "How did you—? I mean, I'm not planning anything! Believe it!"
"I'm Ryota," he said, extending a hand. "I'm new here. And since I don't have a clan or a family cheering for me today, I figured I'd find the loudest person here to be my friend. You seem like you're going to be very loud, Naruto."
Naruto froze. The "demon" child, the boy everyone whispered about, looked at Ryota's outstretched hand as if it were a legendary artifact.
Slowly, tentatively, Naruto took it. "I'm... I'm gonna be Hokage! That's why I'm loud!"
"A bold goal," Ryota said, his eyes glinting with a hint of Aizen's terrifying confidence. "But a Hokage needs a strategist. Someone to handle the... complexities. What do you say? Shall we go change the world?"

Ryota smiled. The work had truly begun. He wasn't just going to survive the Narutoverse. He was going to rewrite it, one soul at a time.
