Chapter 3 – Mangekyō Sharingan
🕑 Added 2025-09-22 16:31:05 +0000 UTC
Uchiha Yato awakened his Sharingan the night his parents died.
He awakened his Mangekyō Sharingan the day Uchiha Kagami, his uncle and guardian, fell in battle.
And now, with the death of Uchiha Michiko, the last person who had cared for him as family, Yato realized the truth—he no longer had anyone left.
A tiger with no restraints is the most dangerous of all. And Yato, at this very moment, was exactly that—feral, unbound, and terrifying.

The Question of Shisui
The silence inside the shrine was suffocating until the Great Elder finally spoke.
“Besides this tragedy,” he said with a heavy heart, “there is also the matter of Michiko’s son—Shisui. His custody must be decided.”
The words struck Yato like a jolt of lightning. His chest, which had moments ago felt hollow and dead, suddenly stirred.
Shisui.
Not all ties were cut. He still had family left in this world.
“Great Elder,” Yato interjected quickly, his voice sharper than intended, “are you saying you want custody of Shisui?”
The old man’s shoulders sagged, his face a portrait of grief. “This old man wishes to, yes. But before her passing, Michiko spoke to me in private. She said… that if she were to die, you, Yato, should raise Shisui.”
The words seemed to drain the elder completely. Though by bloodline he was closer to Shisui, Michiko had entrusted her son to Yato. That decision carried weight greater than blood itself.
The sorrow on the elder’s face silenced the room.
Finally, the clan head, Uchiha Kei, straightened. His usually calm demeanor hardened, his eyes filled with responsibility. “Then we must make it clear.” His voice was firm, carrying authority. “Uchiha Yato, are you prepared to raise Shisui?”
This was no idle question. It was about the life and future of a child. Kei could not treat it lightly.
Yato didn’t hesitate. His answer came like steel striking stone.
“From this day forward, Uchiha Shisui is my younger brother. I will not allow anyone to harm him. And whoever dares—” his voice deepened, his chakra surging with intensity, “—I will take their life.”
As his conviction echoed in the shrine, his eyes shifted. The three tomoe of his Sharingan spun rapidly, merging, reshaping—until they formed a new pattern: a gear-shaped Mangekyō Sharingan.
He let them see. He revealed the Mangekyō not just as a statement but as a warning, a shield, a promise.
Gasps filled the shrine.

The Elders React
The Third Elder surged forward, eyes wide. “Mangekyō…! This is the Mangekyō Sharingan of our clan!” His voice trembled with excitement, his hands shaking as he leaned closer, desperate to take in every detail of Yato’s eyes.
The other elders exchanged stunned glances. They were old enough to remember. Old enough to have witnessed the terrible brilliance of Uchiha Madara’s Mangekyō. They knew exactly what such eyes meant.
Power. Fear. Glory.
The Great Elder swallowed hard, torn between pride and worry. “Yato… when did you awaken your Mangekyō? Have you used it carelessly? The Mangekyō drains ocular power. Use it too much, and you will go blind.” His words carried not only the weight of a clan leader but the concern of an elder for his junior.
Yato shook his head calmly. “No. I didn’t understand these eyes before. Just now, my emotions… overwhelmed me. That’s all.”
The Great Elder’s expression softened. He turned to the gathered jōnin. “Those who are not elders or the clan head—leave now. And keep your mouths sealed tight.”
The order was obeyed instantly. None of the jōnin dared disobey. None were foolish enough to spread word of Yato’s new power. Everyone knew what he was capable of—how he treated enemies and allies with equal ruthlessness when provoked. And no one wanted to invite that wrath.
When the chamber was cleared, the Great Elder continued, his voice grave.
“When the Mangekyō awakens, a unique ocular jutsu is born within it. But every use comes with a cost. Use it too often, and blindness will follow.”
The Second Elder nodded. “And remember—no two Mangekyō are alike. Each grants different abilities. Recklessness will destroy you.”
The Third Elder, calmer now, added, “With the Mangekyō comes Susanoo. But Susanoo too demands heavy sacrifice. Be wise, Yato. You are still young—do not squander your sight.”
Finally, the Great Elder delivered one last warning. “Do not reveal your abilities to anyone—not even to us. This is your secret, and you must guard it well.”
Their words were heavy with both wisdom and fear. The Mangekyō was a treasure—but treasures invited greed.
Yato bowed his head humbly, wearing an earnest expression. “I understand. I will remember your guidance.”
His sincere, studious demeanor, paired with his striking features, softened the elders’ hearts. For a moment, they even forgot he was the infamous troublemaker of the clan.
Satisfied, they brought the meeting to a close.

The Empty Home
That night, Yato returned home. The silence inside pressed down on him. What had once been filled with warmth and family was now empty, lifeless.
He looked around the familiar rooms and felt a pang in his chest.
His first act was to bring Michiko’s body home, laying her gently within the space she had once filled with her laughter. He stared at her face—so familiar, so dear—now cold and still.
The ache in his chest was indescribable.
I can’t let this stand.
Grief alone would not be enough. He needed justice. He needed vengeance.

Suspicions
If it was a foreign shinobi, he thought darkly, then I’ll leave Konoha and make that country pay. At the very least, they’ll shed blood for this.
He remembered Nawaki’s death at the hands of an explosion from the Land of Lightning. Even Orochimaru had dared to storm their territory in retaliation. Yato would do the same if necessary.
But what if it wasn’t a foreign enemy?
Another possibility loomed, more dangerous, more insidious.
In his past life, Yato had read theories about a “Scapegoat Hokage.” And if he had to suspect anyone, the answer was obvious: Danzo Shimura.
Three reasons pointed directly to him.
First, Danzo’s ambition. He had always coveted the Hokage’s position. But on the battlefield in the Land of Rain, Yato’s loud declaration had exposed his schemes, damaging his reputation beyond repair.
Second, Danzo’s grudge. He hated Yato for that humiliation. Unable to strike Yato directly, killing Michiko would be the perfect revenge.
Third—and most damning—Michiko’s Sharingan was missing. In his past life, Yato knew Danzo would one day graft an arm covered in stolen eyes. The timeline might be earlier now, but the motive was clear.
The pieces fit too well.
“Danzo Shimura,” Yato muttered, his voice cold as steel.

The System’s Aid
But suspicion wasn’t proof. Yato needed certainty. And for that, he turned to his cheat.
“System,” he said, “exchange Emotion Points for an Injury Inspection Device.”
Ding.
“Exchange successful. 5000 Emotion Points deducted. Remaining Balance: 100.”
A blinding flash lit the room. When it faded, a small, delicate instrument rested in his hand, decorated with a strange little heart pattern.
Yato stared at it, unimpressed. “…What kind of ridiculous design is this?”
Engraved on the side were the words: “Injury Inspection Device (Naruto Corrected Version).”
He flipped open the manual. The device was a product of higher-plane technology, capable of scanning a body and analyzing injuries with precision beyond any medical ninja.
Exactly what he needed.

The Truth
Without hesitation, Yato activated the device and began scanning Michiko’s body. A faint hum filled the air as lights flickered across the surface of the tool. Yato’s heart pounded in his chest as he watched the screen.
Please… tell me the truth.
Data scrolled across the display.
“Status: Deceased.”
“Cause of death: Blast injury.”
“Additional cause: Toxin infection.”
“Source: Parasitic venomous insect.”
“Effect: Continuous chakra siphoning, leading to fatal weakness.”
Yato’s eyes narrowed. His hands trembled around the device.
Parasitic insects. Chakra siphoning.
There was only one clan in Konoha capable of this—the Aburame.
Which meant someone had used their secret techniques as tools for assassination.
And who else but Danzo had both the ambition and the shadowy influence to command such actions?
Yato’s chakra surged violently, rattling the walls of the empty house. His teeth clenched, his Mangekyō spinning furiously.
“Danzo Shimura… you dare touch my family?” His voice dripped with venom.
He let out a cold, humorless laugh.
“Fine. If you want to play this game, let’s see how long you can hide in the shadows, Scapegoat Hokage.”
