Outer Konoha – Uchiha Clan Compound
Uchiha Yue, having just returned to his modest home on the outskirts of the Uchiha compound, carefully pulled a sealed scroll from inside his robe. As his fingers brushed the inked surface, he felt the familiar thrum of chakra pulsing from within—dense, dark, and saturated with negative emotional residue. A thin smile crept across his lips.
This scroll contained the fruit of his two months of tireless research and planning—his gamble, and perhaps the key to survival. It was also his greatest hope of unlocking the Mangekyō Sharingan.
In the Naruto world, the evolution of the Sharingan—especially the leap to Mangekyō—is fueled by powerful emotional trauma. In canon, Uchiha Itachi gained his after killing his best friend, Shisui. Sasuke awakened his after learning the truth about the massacre and reliving the death of Itachi. Intense sorrow, rage, and despair were essential triggers. As long as the user's physical and spiritual aptitude were sufficient, the Sharingan responded to these outbursts almost naturally.
Now, Yue had already matured his Sharingan to the fully awakened Three Tomoe state. And after three months of focused training and combat simulation, he had completely stabilized and integrated this power. His chakra control, perception, and response speed had grown sharper. Physically, he wasn't yet perfect—but he was much closer to elite Genin or Chūnin standards than he'd been when his memories awakened.
Had he possessed this refined state three months earlier, at the time of his mental collapse, he might have broken the barrier to Mangekyō entirely. The potential had been there. Now, with a strong foundation laid, only one thing remained: the necessary emotional catalyst.
Unfortunately, emotional collapse isn't something one can easily replicate once stabilized. Yue was no longer drowning in fear and denial. He had accepted his identity and his fate—an advantage in some ways, but a setback in this regard.
Still, Yue wasn't the kind of transmigrator to sit and wait for fate to devour him. With the ingenuity of his past life and the knowledge of this world, he began researching a solution. In less than a month, he devised a method to artificially induce the necessary emotional turmoil by refining and sealing large quantities of chakra imbued with negative emotions.
The concept drew inspiration from Tsunade's Byakugō no In—the Strength of a Hundred Seal—where chakra is stored gradually in a seal on the forehead and released during battle for massive temporary power. Yue's method, though less refined, was based on the same chakra storage principle. Instead of raw chakra, however, he channeled negative emotional chakra—rage, grief, helplessness—and compressed it over time into a seal scroll.
Chakra, being a fusion of physical and spiritual energy, is a remarkably flexible medium. In the Naruto universe, it can store not just energy but even consciousness—as seen with the Shadow Clone memory transfers, or Orochimaru's Curse Marks. Storing emotional essence within chakra wasn't as far-fetched as it might seem. Yue simply took it a step further.
Rather than attempting to etch the seal into his body like Tsunade did, he opted for a safer, more convenient alternative: an external storage scroll. The negative chakra was meticulously injected into the seal matrix, layered day by day, until its mass far exceeded Yue's own natural reserves—dozens, perhaps hundreds of times more potent.
To reach that quantity, Yue even ventured into Konoha regularly, deliberately exposing himself to the hostile gazes and whispers of villagers who still viewed the Uchiha with disdain and suspicion. The pressure of daily contempt was a steady fuel. And now, the result was sealed in his hand.
This stockpile of corrupted chakra pulsed with such raw emotion that Yue could scarcely quantify it. It was hatred, despair, resentment, loneliness—every negative thought and fear he'd bottled up since regaining his memories. The moment he released the seal and let it wash over his spiritual core, the explosion of psychological stress would be inevitable.
"It's almost time."
Yue closed his eyes, exhaling slowly. He'd need to meditate, rest, and restore the chakra he'd used to finalize today's refinement. Only then could he initiate the triggering ritual.
"Tonight, I try it. If everything goes according to plan… my Mangekyō will awaken."
"If not… well, there may not be another chance. The massacre is getting closer. Every night, I wonder if Itachi—Konoha's loyal prodigy—will snap early and start cutting us down. He's already unstable. Already watching."
Gently, Yue slid the scroll back into the hidden compartment within his robes, pressing it close to his body like a talisman. Then, turning on his heel, he walked toward the kitchen. He wasn't reckless. Even on the verge of such a breakthrough, he needed to stabilize himself—refuel, calm his body, and ensure every variable was accounted for.
There could be no mistake.
Not tonight.
The time for rest passed in a blink of an eye.
By the time night blanketed the Hidden Leaf, Uchiha Yue had fully restored his physical and spiritual state. His breathing was calm, his mind steady—like a drawn blade awaiting release.
"Phew… Now's the time. Whether I soar as a dragon or fall as a worm—whether I live, or perish—all hinges on whether my theory holds true."
He stood in the center of his dimly lit room, the faint glow of sealing tags casting flickering shadows across the walls. He had already shut the door and erected a basic chakra barrier—just in case his chakra destabilized mid-process. Holding the scroll that contained the fruit of his three-month endeavor, Yue murmured to himself, then unsealed it without hesitation.
A thick, roiling tide of chakra surged out—dense, heavy, and utterly vile in its emotional weight. Yue opened himself to it. The moment it entered his tenketsu, everything shifted.
Boom!
His senses were swallowed in an instant. It was as if his consciousness had been cast into a violent ocean—an abyssal current of sorrow, hatred, grief, and rage. It wasn't foreign. No, it was his—born from his own despair, cultivated from his own fears and traumas. These were the same negative emotions he had meticulously harvested over two months, bit by bit, without flinching.
But now, absorbed all at once, they returned like a tsunami—drowning his reason and threatening to tear his ego apart.
Because this chakra was made from his own emotional residue, the surge didn't just overwhelm him—it catalyzed a recursive effect. The emotions triggered memories, the memories triggered more pain, and the pain gave rise to even darker emotions. His mind spun downward, further and further, until it felt like nothing remained of Uchiha Yue except suffering.
But even in the pitch black, a spark remained.
He had experienced this once before—on the night his past-life memories returned and shattered his sense of reality. He had clawed his way back then with sheer will. And now, with that same iron will forged through adversity, training, and determination, Yue clung to his last strand of self.
The will to live.
The hunger for power.
The defiance of fate.
The dream of protecting what little he had left.
All these burned together like a beacon—keeping him from losing himself entirely to the storm. Bit by bit, his consciousness stabilized.
Time passed. He didn't know how long. But then—it happened.
A wave of killing intent radiated from his body as his chakra exploded outward in all directions—cold, violent, unearthly. His features twisted in strain and exertion. His chakra signature now carried a dreadful chill that made the air itself hum.
And in his blood-red eyes, something extraordinary was taking shape.
The three tomoe spun wildly, faster and faster—until they began to collapse inward. With a final jolt, they contracted completely… and reformed.
A new, unique pattern bloomed in his irises.
Mangekyō Sharingan—awakened.
The weight of the chakra vanished. The storm receded. A profound stillness settled inside him.
In that moment, Yue felt his soul ascend. It was as if all the emotion, all the agony, had been distilled and crystallized into something higher—beyond human volatility.
"So this… is the Mangekyō Sharingan?"
Even in the dim room, he could see everything with perfect clarity. His vision wasn't just sharper—it was deeper, as if peeling back the layers of existence itself. The chakra threads in the air, the faintest shifts in temperature—everything became evident.
More than that, he could feel something stirring within the eyes themselves. Faint whispers—no, instructions. The unique power of his Mangekyō—his exclusive pupil technique—was already transmitting itself to his brain, waiting to be understood and unleashed.
"It's overwhelming. This isn't just an evolution—it's another realm entirely."
He stood still, heart pounding, overwhelmed not by fear but by quiet exhilaration. The darkness had passed. The gamble had paid off. He had seized control of his destiny—if only for now.
Uchiha Yue smiled.
In the end, he had succeeded.
He had taken the future into his own hands.
