[Gengetsu Hōzuki]: Well, well. So it was you causing trouble all along! Fuguki Suikazan, you traitorous bastard!
[Fuguki Suikazan]: Lord Mizukage, you can't really blame me. If you want to blame someone, blame that guy Obito. Besides, among the Seven Ninja Swordsmen of the Mist, Jūzō, Zabuza, and Raiga all defected, didn't they?
[Gengetsu Hōzuki]: Huh? But the others among the Seven Ninja Swordsmen didn't defect!
[Jūzō Biwa]: That's because… they were all beaten to death by Might Duy. How could they defect if they were already dead?
[Gengetsu Hōzuki]: ...
Damn it, our Kirigakure and your Konohagakure have a grudge because—
…Wait, come to think of it, we actually do have a grudge.
[Genma ]: But Ibiki, you're pretty impressive. You actually scared Kisame away.
[Iwashi Tatami]: Hahaha! If I could scare off Itachi's partner like that, I'd brag about it for years.
[Ibiki Morino]: ...
Wow. Since when was I that amazing?
The screen continues
Nagi looked at Kisame's corpse and sighed.
He knew the Kisame before him wasn't a White Zetsu impersonation.
So he crouched down and sealed Kisame's body inside a sealing scroll.
Then Nagi casually fired a Water Release: Water Gun Technique toward a nearby tree.
The hidden Black Zetsu and White Zetsu lurking inside the trunk were startled. They immediately withdrew and fled into the tree to escape.
Meanwhile, the Uchiha hideout had been reduced to ruins.
Two gigantic half-bodied Susanoo clashed violently—
one clad in crimson armor, the other in purple armor.
After several exchanges, the crimson giant swung the Totsuka Blade, blasting the purple Susanoo backward dozens of steps.
Both Sasuke and Itachi were now breathing heavily.
Watching from a distant tree branch, Nagi sighed.
"Sasuke's getting carried away again."
Sasuke's Susanoo possessed the spiritual weapon Ame-no-Magatsu Bow, a long-range weapon.
Yet Sasuke stubbornly insisted on engaging Itachi—who wielded the close-range Totsuka Blade—in hand-to-hand combat.
Itachi deliberately provoked him:
"Sasuke, if this is all the power you have, it's still far from enough.
Your conviction isn't strong enough. With resolve like that… you think you can kill me?"
Hearing this, Sasuke remembered the current state of the Uchiha clan…
Itachi's pride…
and the revolution Nagi hoped to bring about.
"I, Uchiha Sasuke, will definitely restore the Uchiha clan!"
"Nagi has helped me so much… I absolutely cannot betray the expectations he has for me!!"
"AAAAAHHH!!"
With unwavering determination, Sasuke roared toward the sky.
Itachi simply watched him silently.
From the distant tree trunk, Nagi narrowed his eyes.
"It's coming."
"AAAAAHHH!!"
Suddenly, purple chakra surged violently from Sasuke's body.
The crimson hexagram pattern in his eyes grew even more vivid.
"Hmm?"
Itachi immediately sensed something was wrong.
Meanwhile, Nagi smiled faintly.
"So it's finally happened… the Eternal Mangekyō Sharingan."
When Nagi helped Sasuke awaken the Mangekyō Sharingan, Sasuke's Yin Release chakra had already surpassed the threshold required for it.
What separated Sasuke from the true Eternal Mangekyō Sharingan was merely:
emotional chakra equivalent to another pair of Mangekyō Sharingan
and a small amount of high-quality Yin Release chakra.
After all, Sasuke carried Indra's chakra hidden within his body.
Because of that, his training speed with Yin Release chakra far surpassed that of any other member of the Uchiha clan.
"Just as Orochimaru and I predicted.
Itachi's stimulation, combined with Sasuke's strengthening resolve, would forcibly awaken a portion of Indra's chakra."
"That would allow emotional chakra and Yin Release chakra to fuse together, producing dōjutsu that directly surpasses the threshold… and ultimately complete the evolution."
[Ōnoki]: What the hell?! So Nagi and Orochimaru predicted from the start that Sasuke would awaken the Eternal Mangekyō Sharingan during this battle?!
[Rasa]: The intelligence of those two is truly beyond imagination.
[Madara Uchiha]: Hmph… the Eternal Mangekyō Sharingan, huh…
Madara felt a complicated mix of emotions.
After all, Nagi and Orochimaru had enabled Sasuke to obtain the Eternal Mangekyō Sharingan without transplanting a sibling's eyes.
[Konan]: Then will Nagi help Sasuke awaken the Rinnegan next?
[Nagi]: That depends on the future.
[Madara Uchiha]: The Rinnegan, hm? Indeed. As long as the boy cultivates his Yin Release chakra to a certain level and receives Hashirama's cells, awakening the Rinnegan shouldn't be difficult.
Hearing this, Nagi lowered his head in thought.
Madara's method was indeed the most efficient.
But it wasn't the only path.
One could also pursue the path of cultivating pure, extreme Yin Release chakra alone—though that road was far more difficult, and even Nagi and Orochimaru were unsure of the final outcome.
The screen continues
Sasuke's third-stage Susanoo suddenly regressed to its second form.
However, this second form had now grown lower limbs, and its body was far larger than before.
Itachi stared intently at the change.
Suddenly he seemed to realize something.
"Sasuke… don't tell me you—!!"
Sasuke replied:
"To be honest, I don't fully understand what's happening to me right now.
But I can feel that my dōjutsu is completely different from before."
"Is that so… Sasuke, impressive."
A look of relief appeared on Itachi's face.
Then he dispelled his Susanoo.
Seeing this, Sasuke shouted angrily:
"What's going on? Are you looking down on me?!"
Itachi shook his head.
"After using Susanoo so extensively, my dōjutsu is nearly exhausted.
Besides… seeing you like this, Sasuke, there's no longer any need for me to contin—"
"Urgh!"
"Cough! Cough!!"
Suddenly, Itachi clutched his chest, his face twisted in pain.
Sasuke immediately remembered what Nagi had once said:
Itachi was already terminally ill.
Sasuke dispelled his Susanoo and walked toward him.
After a while, Itachi stopped coughing, his expression easing somewhat.
Sasuke stood before him.
Itachi spoke:
"Sasuke… you've surpassed me. I'm very happy."
"Next… please don't resist."
"Tsukuyomi."
Through Tsukuyomi, Itachi showed Sasuke the truth behind the Uchiha clan massacre.
Sasuke realized that what he saw in the genjutsu was almost exactly the same as what Nagi had previously told him.
The only difference was—
"So it was you, Nagi… who protected the surviving Uchiha children?"
When the vision ended, their consciousness returned to reality.
Itachi said softly:
"Sasuke… I'm sorry. I always treated you like a child and tried to control the path of your life."
"But now, you no longer need me to guide you."
"I can die without regrets."
He noticed Sasuke's trembling hand gripping the Kusanagi Sword.
"Sasuke… I am the sinner of the Uchiha clan. And my life is already nearing its end."
"Only by killing me can you grant me release."
"So you don't need to feel guilty."
Tears welled in Sasuke's eyes.
If he killed his brother now…
Memories of their childhood together flooded his mind.
Happy moments. Warm moments.
Itachi was his last remaining family in the world.
But he also remembered the children of the Uchiha clan who had lost their parents.
He remembered the quiet days when he would spend time with them.
Itachi spoke again:
"Sasuke… I'm sorry you have to make such a painful decision."
"But you must grow."
"So that one day, you will never have to make a choice like this again."
"Sasuke… do it."
After a long silence…
Sasuke wiped his tears away.
His eyes were filled with determination.
He raised the Kusanagi Sword, aimed at Itachi's heart—
—and thrust.
Itachi looked at Sasuke with a gentle smile, his eyes full of relief.
"Yes… that's the look, Sasuke."
"Only with eyes like that can you face the decisions that lie ahead."
Uchiha Itachi… has died.
