"Say it!"
Itachi Uchiha narrowed his eyes slightly.
[The Sharingan with its three tomoe in each eye begins to rotate.]
Its finger stopped in front of Sasuke's three-tomoe Sharingan.
"The Mangekyou Sharingan is destined to lead to darkness."
"The countdown began the moment you opened your eyes."
"You've overused your Mangekyou Sharingan."
"By now, your vision should be blurry, right?"
Itachi Uchiha suddenly smiled again.
[It's very strange.]
However...
Even when Itachi's hand was almost touching his eye, Sasuke remained completely still.
The coldness in his eyes remained undiminished.
"You're eager to catch up with me."
"The Mangekyou Sharingan must have been overused, causing his vision to become blurred."
"You must have noticed that too."
"So, from the moment you walked in, you only activated the Sharingan, not the Mangekyou Sharingan."
"Given your personality, you wouldn't appear in front of me like this."
"They wanted to save the game for last to decide the outcome."
"Kill me before the Mangekyou Sharingan completely succumbs to darkness?"
[Looking at the self-important Uchiha Itachi.]
Sasuke suddenly felt a pang of sadness.
I feel sorry for myself.
[I can't believe I've called someone like that "brother" for so many years.]
[Sudden. ]
Itachi Uchiha took a step back.
[He revealed a smile even more manic than Sasuke's.]
[Hahaha~]
"But..."
"Say it!"
"I'm different!"
"I've found a way!"
"We've found a way out of the darkness!"
"I've been nurturing you all along, and this is the day you've finally awakened the Mangekyou Sharingan!"
[Itachi Uchiha covered his eyes, laughing maniacally.]
"I've finally obtained power that surpasses Madara Uchiha!"
"You are a new light to me!"
"That's why I spared your life!"
"Say it!"
["Say it~!"]
"Be my light!"
*Snap*
Without any warning.
Itachi Uchiha's laughter abruptly stopped.
Its face was now tilted to the other side.
["First."]
"You are destined to walk into darkness."
["second."]
"Don't blame everything on the Mangekyou Sharingan."
"You are nothing but an animal."
["third."]
"Uchiha Madara?"
"You mean that guy with the orange swirl mask?"
Itachi Uchiha paused for a moment.
[Then, from a position where Sasuke couldn't see him.]
Its expression suddenly darkened.
As expected.
Sasuke finally encountered that "Uchiha Madara"!
[The agreement was not kept!]
"You've seen it?" Itachi Uchiha asked.
["No."]
"However, surpassing Uchiha Madara?"
["Hehehe~"]
"You're so happy to surpass a piece of trash like Obito Uchiha, a disgrace to the Uchiha clan?"
Itachi Uchiha frowned.
[Uchiha...]
[Obito?]
[So it really wasn't Uchiha Madara?]
But wasn't Obito Uchiha already dead?
Several questions arose in Itachi's mind.
At this moment, Sasuke added:
"That's enough."
"This boring illusion is over."
"As for your carefully crafted lies, there's even less need to continue."
"Fully riddled with flaws."
[Buzz—]
[The instant Sasuke finished speaking.]
The whole world is broken.
[Double Illusion.]
However...
This time, Sasuke wasn't at the door.
Instead, they remained standing in the same spot.
[Uchiha Itachi never left the head seat from beginning to end.]
[Above.]
Itachi Uchiha slowly opened his eyes.
Those eyes were, of course, in the shape of the Mangekyou Sharingan.
[Even the moment Sasuke stepped into the former Uchiha headquarters.]
It's already turned on.
[certainly. ]
This double illusion is not Tsukuyomi.
Otherwise, it would immediately alert Sasuke.
"Sasuke."
"You've grown a lot."
Sasuke said indifferently:
"So that I can kill you with my own hands."
"My eyes."
"In the world of Tsukuyomi, I watched you slaughter your entire clan again and again."
"Itachi."
"I remember every single one of the people you killed very clearly."
"I saw all their emotions."
"You've probably forgotten a lot, haven't you?"
["It doesn't matter."]
"I remember everything; I remember the expressions on the faces of every member of my tribe."
[far away. ]
Naruto watched this scene with great interest.
A battle between brothers.
No one has touched it since we met.
Of course, this is how it appears to outsiders, even those with the Rinnegan.
But Naruto will be able to witness the 'opening ceremony' of the brothers' battle.
[A battle of illusions.]
[In the realm of genjutsu, which Itachi Uchiha excelled at.]
Sasuke broke the genjutsu with the air of a victor.
"The Uchiha clan."
"It was all for power."
"To awaken the Mangekyou Sharingan, he didn't hesitate to kill his best friend; to obtain eternal eye power, he didn't hesitate to turn against his father and kill his own siblings!"
"This is the Uchiha!"
Uchiha Izuna: I don't agree.
Uchiha Izuna: Tobirama Senju, who was born evil, is going to generalize again.
Tobirama Senju: "???"
Did I say anything?!
...
["and."]
Itachi Uchiha's smile faded.
"And they've always been proud of this power!"
"Say it!"
[Uchiha Itachi suddenly roared.]
He then charged towards Sasuke.
Sasuke shook his head.
["fourth."]
["never mind."]
"Your arrogance, conceit, and selfishness will never lead to understanding; it's a waste of your breath."
[Buzz—]
[In an instant.]
Sasuke's rapidly spinning three-tomoe Sharingan transformed into a six-pointed star.
[Eternal Mangekyou Sharingan!]
[Itachi Uchiha was momentarily stunned.]
And in just that brief moment...
Sasuke had already raised his hand.
The Thousand Birds Stream pierced its heart.
The situation reversed instantly.
[Until the moment the Mangekyou Sharingan was awakened.]
Sasuke already knew.
How significant is the difference between the Sharingan and the Mangekyou Sharingan?
[Gah——]
At this time.
Itachi Uchiha slowly emerged from behind the head seat.
[The Uchiha Itachi, pierced by the Chidori Stream, transformed into countless crows and flew away.]
"Eternal... Mangekyou Sharingan?!"
This time.
A genuine look of astonishment appeared on Itachi Uchiha's face.
This can't be right!
Because one's own eyes are still in their own eye sockets.
How could Sasuke possibly have awakened the Eternal Mangekyou Sharingan?!
"People rely on their own knowledge and understanding, and are bound by these things."
Therefore, people live in the world they imagine.
"Just like you believe, it's the only way to escape the darkness and awaken the Eternal Mangekyou Sharingan."
[Uchiha Itachi: !!!]
"Amaterasu!!!"
