Itachi stared at the spinning pattern in his fathers eyes and spoke the single word in a voice filled with quiet surprise.
“Father.” Fugaku nodded once and began to explain,”Yes this is the Mangekyo Sharingan.
I awakened it during the start of the third great shinobi war when I lost my closest friend myself.
And it is also the reason that I took you to witness what awaits a shinobi in a war.” “I never intended for anyone to know that I possessed it.
Not many people in the village even remember that such an advanced form of the Sharingan exists.
Yet the Third Hokage and the village elders do know the old records.
If they ever learned that I held these eyes they would almost certainly blame me for the Nine Tails attack on Konoha.” “Only an Uchiha who has awakened the Mangekyo can control a tailed beast the way Madara Uchiha once controlled the Nine Tails against the First Hokage.
I refused to give them any reason to place that crime on my shoulders.” He continued without pausing.
“I never told a single person inside the clan either.
Not even the elders.
If they learned of this power they would see it as a perfect opportunity to push the coup forward with greater confidence.” “I also kept the secret from your mother.
She would only worry.
She knows that the Mangekyo can awaken only when a person experiences grief and sorrow so deep that the ordinary Sharingan itself acknowledges the pain and evolves to contain it.
I did not want her to worry further.” Itachi listened carefully and made a private decision in that moment.
He would not tell his father that he too now possessed the Mangekyo.
One Uchiha with these eyes was already a dangerous secret.
Two such Uchiha would be enough to change the balance of any future conflict and he was not ready to place that knowledge in anyone elses hands.
He asked the question that followed naturally.
“Then why tell me tonight of all nights?” Inside the shared mind the original Itachi remained completely silent.
He offered no advice and no protest.
He simply watched.
Fugaku answered with quiet honesty.
“Because if there is another Uchiha in this clan who could one day feel pain even greater than the pain I have carried it is you.
I hope with all my heart that you never experience the kind of loss that forces the Mangekyõ to awaken.
Yet I also know that such loss is woven into the destiny of our bloodline.
Sooner or later the eyes demand their price.” Without another word Fugaku turned fully toward the ancient tablet.
His Mangekyo focused on the weathered symbols that covered its surface.
He spoke while still studying the stone.
“Only someone who has awakened the Mangekyo can read the words written on this tablet.
It was made by the Sage of Six Paths himself and left for the Uchiha.” At those words Itachi activated his own Mangekyo for a brief second while his father’s back was turned to him.
The meaningless markings on the tablet slowly rearranged themselves into clear language that he could understand.
As soon as the meaning formed he closed the eyes again.
After several moments of silence, Fugaku began to speak the words of what was written on the tablet.
“The Sharingan is born from powerful emotion.
Through suffering the eye matures.” He continued without change in tone.
“When both eyes awaken to the Mangekyo Sharingan the user gains power beyond that of ordinary shinobi.
Yet every use of those eyes brings them closer to darkness.” “Vision fades with repeated use.
Eventually even the light itself disappears.” Itachi already knew this truth.
As the clan heir, he was taught the history of the Mangekyo and the blindness that followed its overuse.
The knowledge had been part of his earliest lessons.
Fugaku kept reading.
“Those who pursue greater power must accept blindness as its inevitable price.” The next passage followed at once.
“When the eyes of close ones become one, eternal light is restored.
The darkness is dispelled and a new Sharingan is born.” Inside his thoughts Itachi formed a clear realisation.
‘So the blindness can be overcome after all.
There is a path back to sight if the right conditions are met.
But what does it mean by the eyes of the closed ones?
Hmm.’ Fugaku continued, “Seeking stability one god was divided into yin and yang.
These opposing two acting together obtain all things in creation.” Itachi frowned,’It has moved from Sharingan to something else.
What is the sage trying to say and how do we even know that the sage himself has written this?’ Fugaku read the following lines.
“From yin came form without substance.
From yang came life without shape.
Together they became the origin of all creation.” Itachi thought to himself with mild frustration.
‘Can the Sage of Six Paths never say what he means in plain words?
Why must every important truth be wrapped in mysterious ramblings that leave a person guessing?’ “When someone who possesses the power of Samsara approaches the moon an eye will open that is reflected upon the moon to grant the Eternal Dream.” Itachi turned the strange words over in his mind.
‘An Eternal Dream.
The description sounds similar to Tsukuyomi yet larger and heavier in scale.’ The chamber remained silent for a long time after Fugaku finished reading.
At last Itachi broke the quiet.
“Father.” Fugaku looked at him and waited.
Itachi spoke the truth he had already understood.
“You did not bring me here only to show me a stone tablet and read old words.
There is another reason.” It was not a question.
It was a statement of certainty.
Fugaku regarded his son for several full seconds before he answered.
“No.
The tablet was only part of the purpose.” He turned away from the stone and began walking slowly toward the steps that led back to the surface.
“I brought you here because I was worried about you.” Those words caught Itachi off guard far more than the sight of the Mangekyo had done.
He had expected lessons about power or warnings about the future.
He had not expected simple parental concern.
Fugaku continued speaking as he walked.
“When the report of Shisui’s death reached you, you accepted it without protest.
You did not cry in front of your family.
You did not shout or break.
You did everything that a well trained shinobi is expected to do in the face of loss.” He stopped at the foot of the stairs and looked back.
“But you did none of those things as a twelve year old boy who had just lost his closest friend.
You acted only as a soldier.” Itachi lowered his gaze and answered with the only truth he could offer.
“I am a shinobi.” Fugaku replied at once.
“You are.
That fact is clear to everyone who watches you.
But that is not all you are.
You are also my son and Sasukes brother and a child of this clan who is allowed to feel pain.” The words hung in the cool air of the underground room.
For a long moment Fugaku said nothing further as if he were deciding how much more to reveal.
When he spoke again his voice stayed level and almost detached.
“When I was your age I also believed that enduring every wound in complete silence was the purest form of strength.
I locked every grief behind a calm face and called it duty.” He paused and then finished the thought.
“I learned later when I met your mother that there is very little real strength in pretending that pain does not exist.
The pain remains whether you acknowledge it or not.
It simply grows heavier when you refuse to look at it.” Itachi listened without interruption.
Fugaku continued in the same quiet tone.
“I cannot take the burden from your shoulders and carry it for you.
No one can.
Each person must hold their own grief.
But I can make certain that you do not mistake the act of carrying pain for the act of ignoring it completely.” “I showed you this because every clan head eventually stands in the same place I stand tonight.
And you are the heir who will one day take my position.
The tablet is part of that preparation.” He rested a hand on the edge of the ancient stone.
“Clan heads lose comrades.
They lose family.
They are forced to make decisions that can never be undone.
The tablet contains answers to some of the questions that arise in those dark hours.” He paused and then added the deeper reason.
“But more importantly it reminds us that the Uchiha who came before us also carried burdens they could not fully understand.
We are not the first to search for meaning in suffering.
We will not be the last.” For the first time that night a faint trace of softness entered, Fugaku’s voice.
“When I first read this tablet I believed its only purpose was to teach me about the growth and the limits of the Sharingan.
I was wrong.” Itachi asked the natural question.
“What is its real purpose then?” Fugaku answered without any hesitation.
“To remind me that no matter how capable and prepared I believed myself to be there would always be things that remained beyond my understanding.
The tablet teaches humility as much as it teaches power.” Itachi asked the final question that still needed an answer.
“Why did you choose to bring me here on this particular night?
You could have showed me this on any other day.” “Because after Shisuis death I realised that you needed your father more than you needed the clanhead of the Uchiha clan.” Itachis expression did not change.
Fugakus expression did not change either.
Yet something unspoken and important passed between them in the quiet of the shrine.
After a few more moments Fugaku turned fully toward the stairs.
“Come.
We have kept your mother waiting long enough.
She will not rest until both of us are home.” Itachi followed one step behind his father.
Together they climbed out of the hidden chamber and back toward the surface.
Neither of them spoke another word as they left the Naka Shrine behind.
