As is well known, the exclusive ocular techniques in the Naruto world are named after gods from Yagyu's previous life in Japan.
Whether it's the Mangekyō Sharingan or the Rinnegan's exclusive techniques, they all follow this pattern.
Japanese mythology features eight million gods, most of whom are actually yōkai (supernatural creatures).
Additionally, many of these gods hold multiple divine roles or have held different roles in the past, so they often have alternate names.
For example, Yagyu's Mangekyō Sharingan's exclusive technique, Yomi no Tsukai, is known in Japanese mythology as Yomi no Ōkami.
Yomi no Ōkami is another name for Izanami, the goddess of creation and death.
However, in the Naruto world, these two names represent different ocular abilities.
Similarly, Yagyu's Rinnegan's exclusive technique, Outer Path Maru, is also famous in Japanese mythology.
This is the true name of Shuten-dōji, one of the three great yōkai.
Of course, in the Naruto world, it's simply the name of a Rinnegan technique.
But the ability of this technique shocked Yagyu, making him seriously question whether it was something a Kekkei Genkai could possess.
Even Kekkei Mōra and the divine techniques of the pure-blooded Ōtsutsuki clan couldn't compare, could they?
Just like Yachihoko, the exclusive Mangekyō Sharingan technique of Uchiha Hikari, which was a cheat-level ability, Yagyu's exclusive technique, Outer Path Maru, was undoubtedly an overpowered and insurmountable existence.
Offense, defense, and ultimate support all in one…
With the help of this exclusive technique, Yagyu's path to reaching the level of the Sage of Six Paths and Kaguya Ōtsutsuki would be as easy as pie.
Thinking this, Yagyu couldn't help but want to show off this exclusive technique immediately.
However, considering the next step of his plan—the final phase—he suppressed his eager thoughts.
No rush. He'd wait until the greatest treasure appeared.
Thus, Yagyu teleported back to the battlefield.
By now, the cocoon that had sealed Madara Uchiha had already disappeared.
This didn't surprise Yagyu.
Before he left, he had glanced in a certain direction, where Black Zetsu was hiding.
With Yin-Yang Release and Wood Release, Black Zetsu could easily undo Yagyu's seal.
Allowing him to rescue Madara Uchiha was also part of Yagyu's plan.
After all, for Kaguya Ōtsutsuki to be revived, unless the moon was destroyed, the only way was for her will to possess the Ten-Tails Jinchūriki and use them as a vessel for her resurrection.
Reviving Kaguya Ōtsutsuki was the final stage of Yagyu's plan.
The game system was Yagyu's greatest cheat, allowing him to leap from one level of power to another, much like Naruto and Sasuke had received power-ups from the Sage of Six Paths.
Dropping the Rinnegan from Madara Uchiha and instantly awakening his own Rinnegan was just the beginning.
The true pinnacle, Kekkei Mōra, which combined all seven nature transformations and surpassed Kekkei Genkai and Kekkei Tōta, was Yagyu's ultimate goal.
Now that he had awakened the Rinnegan and his power and level had entered the Six Paths tier, Yagyu was confident he could face the Ten-Tails Jinchūriki and the Sage of Six Paths without fear.
Especially with Yomi no Tsukai, which could kill souls, Limbo: Border Jail, which he had dropped from Madara Uchiha, and his own Rinnegan's exclusive technique, Outer Path Maru, Yagyu was certain he could defeat them.
As long as the plan went smoothly, by the end of the war, Yagyu's strength would reach the pinnacle of the Six Paths level, on par with Kaguya Ōtsutsuki and the Sage of Six Paths.
At that level of power, even among the pure-blooded Ōtsutsuki from beyond the stars, few could compare.
With such strength, Yagyu wouldn't have to fear Isshiki Ōtsutsuki, who was hiding in some unknown corner.
Thus, Yagyu's figure disappeared without warning.
When he reappeared, he wasn't on the ninja alliance's battlefield but in the underground base of Amegakure.
Now that he had obtained the Rinnegan, it was time for Hyakugan to make a reasonable exit.
After all, this most special Wood Clone had been created by Yagyu to gather intelligence on the Akatsuki, ensure the plan's success, and see if he could obtain Madara Uchiha's body to secure absolute control.
Now that the objective had been achieved, it was time to ease some of the pressure on the ninja alliance.
Thus, Yagyu and Hyakugan staged a battle that destroyed the underground base. Then, with lightning speed, Yagyu subdued Hyakugan and forced him to undo the Reanimation Jutsu, causing all the reanimated elite squad members on the battlefield to ascend to the afterlife.
"What's going on?!"
"The Reanimation Jutsu has been undone. Did someone find the caster?"
"Only some of the reanimated have been released. It must be Orochimaru or Hundred Faces's doing. Which one died?"
"Hundred Faces or Orochimaru?!"
"Great! The reanimated elites have been released—the Third Raikage, the Second Tsuchikage, and the Second Mizukage are all gone. Did Lord Yagyu do this?"
"..."
Beams of white light shot into the night sky, immediately sparking cheers across the battlefield.
The ninja alliance's elite forces had been under immense pressure.
The Third Raikage was a Kage-level powerhouse on par with Ōnoki. Among those present, only three and a half people could handle him.
One was Ōnoki, another was Might Guy, who could open the Seventh Gate, and the last was Kakashi Hatake, whose Kamui could distort space and counter the Third Raikage's absolute defense.
Even if Might Guy opened the Seventh Gate, he couldn't defeat the Third Raikage, whose body could withstand the Rasenshuriken and Tailed Beast Bombs—unless he sacrificed his life to open the Eighth Gate.
In that case, he would be the star of the battlefield for a short time.
If he was lucky, he might even end the war.
But considering that Itachi Uchiha could use Izanami even in his reanimated form, and both Madara Uchiha and Obito Uchiha could sacrifice an eye to escape death, Might Guy's sacrifice would likely be in vain.
Once they became the Ten-Tails Jinchūriki, their lost ocular power would be restored, and Might Guy's death would be meaningless.
So even if he opened the Eighth Gate, there was a 99% chance he wouldn't be able to end the war.
The Third Raikage alone had tormented the ninja alliance's elite forces. Add to that the Second Tsuchikage, whose lethality surpassed even the Third Raikage's, and the Second Mizukage, who had once fought the Second Tsuchikage to a mutual death, and the pressure was overwhelming.
These three were all Kage-level powerhouses.
If not for Ōnoki, Tsunade, Gaara, Mei Terumī, and the significantly buffed Sakura, Hinata, Ino, and Kurama Yakumo, who together were on par with the Five Kage, as well as Kakashi Hatake, who could use Kamui more frequently with the help of Katsuyu, the ninja alliance's elite forces would have been annihilated long ago.
Even so, the ninja alliance's elite forces had suffered heavy casualties, including many strong individuals from Konoha.
Hyakugan had been impartial, killing elites from all five major villages and the Land of Iron, nearly causing a generational gap.
Even if the Five Kage survived, they would have no successors for the time being.
Retiring at the age they did in Boruto would be difficult.
However, Hyakugan hadn't gone all out. He had only killed the well-known elites from the original story, as well as some with massive chakra reserves who had never appeared or only had a single panel in the original story. Many special jōnin and jōnin had been spared.
Elites like Chōjūrō, Kurotsuchi, and Ao had all been killed.
The rest were left to maintain the current ninja world order.
With the reanimated elite squad ascending to the afterlife, the ninja alliance's pressure was drastically reduced, dropping from hellish difficulty to easy mode.
The only Kage-level opponents left were Deidara and Kisame Hoshigaki.
Even Hidan and Kakuzu had ascended.
Seeing this, Kisame and Deidara's expressions changed drastically.
Upon closer inspection, Deidara's face showed a hint of fanaticism.
The feeling of being in a desperate situation seemed to awaken a sense of mission in this artist, much like Might Guy opening the Eighth Gate in the original story.
This situation might be the perfect moment to bring his explosive art to its peak.
Unfortunately, Deidara didn't have the chance to self-destruct.
What awaited him and Kisame was a joint assault from multiple Kage-level fighters.
The Fourth Great Ninja War, which surpassed even the First Great Ninja War in scale below the Kage level, had now given the ninja alliance an absolute advantage.
The key to victory now lay in the battles of those who surpassed the Five Kage and the five major villages—the battles of the Super Kage level.
Meanwhile, Madara Uchiha, who had broken free of the seal with Black Zetsu's help, had arrived on the battlefield.
"Your weapon, returned to you."
Seeing Madara Uchiha appear beside him, Obito Uchiha, who had used the method provided by Black Zetsu to connect himself to the Ten-Tails, remained calm.
With the Ten-Tails' chakra at his disposal, Obito was confident that Madara couldn't use the cursed seal to take control of him. Otherwise, Madara would have already been revived.
If Madara made any moves, Obito would immediately become the Ten-Tails Jinchūriki using the Ten-Tails Coffin Seal Technique.
After all, Madara was just a dead man, and his Rinnegan were fake. The initiative lay with Obito, the true Rinnegan wielder.
If Madara dared to tear off the mask, Obito was prepared for a mutual destruction.
Thus, while controlling the Ten-Tails to deal with Naruto and Sasuke's combined assault, Obito wasn't the least bit panicked when Madara appeared. In fact, he felt the pressure ease and casually tossed his scythe to Madara.
However, when Madara caught the scythe, he frowned.
Seeing that Obito hadn't retrieved a new weapon, Madara asked, "Where's the Gunbai?"
"I used it in a trade," Obito replied indifferently.
"Wasteful brat."
Madara rarely scolded anyone, but he couldn't help it this time. "The Gunbai is a treasure of the Uchiha clan, capable of deflecting any attack. And you just traded it away?"
"If I hadn't, you wouldn't be seeing the Ten-Tails now."
Obito watched as beams of light shot into the sky, his brow furrowing. "But now, the Gunbai must be in someone else's hands. Did you kill that brat Yagyu?"
"No, he almost killed me."
Madara, who seemed to know who now possessed the Gunbai, accepted his defeat with surprising ease. He grinned and praised, "That brat is incredible. Not only has he surpassed Hashirama in Wood Release development, but he's also reached the pinnacle in ninjutsu, taijutsu, and genjutsu. Only after I'm revived will I be able to defeat him."
Madara wasn't discouraged or frustrated by Yagyu's tactics. After all, strategy was one of a shinobi's weapons.
If anything, he only had himself to blame for underestimating Yagyu and falling into his trap.
But as he said, losing to Yagyu in this state didn't matter.
This wasn't Madara's full strength.
Only after being revived and reclaiming his eyes would he be at his peak.
Fully aware of the power of Limbo: Border Jail, Madara didn't believe Yagyu could defeat him at his full strength.
Obito, who understood Madara's thoughts, changed the subject. "Let's deal with these two brats first. If Yagyu shows up, the situation will get worse."
Madara also understood Obito's intentions and sneered inwardly.
However, he couldn't seize control of the Ten-Tails from Obito at the moment, so he nodded and examined the golden Nine-Tails and the purple Susanoo with interest.
"A Complete Body Susanoo, and with this level of ocular power… I never expected this era to produce someone with eyes like mine."
Madara then scrutinized Sasuke Uchiha, who was inside the Susanoo's forehead. His expression shifted to one of surprise. "Izuna? No… this brat… he looks like Izuna. And his eyes are straight tomoe, just like mine."
Next, he turned his gaze to Naruto, who was inside the Nine-Tails' forehead and now staring at him in shock. Madara couldn't help but marvel, "Yagyu, and these two brats… they're all so young. This era actually produced such little monsters?"
Even the proud Madara Uchiha couldn't help but feel that the younger generation was surpassing the old.
When he and Hashirama had reached this level of power, they were already in their middle age, and Hashirama even had a son.
But Yagyu and these two brats were clearly still teenagers.
At this age, even during the Warring States Period, they would have been old enough to marry but not to lead a clan, let alone become the strongest shinobi capable of ending the era of war.
Yet this era had produced three individuals who, if placed in the Warring States Period, could have ended the chaos and unified the ninja world.
Madara suddenly felt that this was the greatest test the heavens had set for him to sever karma and establish true peace.
With this thought, a look of excitement appeared on Madara's face.
He wanted to see just how big this test was. Bring it on!
