Although Naruto is doing well now, his childhood experiences are still deeply etched in his memory.
Being kept in the dark, suffering rejection from everyone, and being subjected to omnipresent, disgusted stares.
Occasionally, when Naruto spends time with unfamiliar children, adults will come and chase Naruto away, and his original friends will join in bullying and ostracizing Naruto.
The Dark Side says Naruto forgot, but how could Naruto forget? Some things he never thinks about, he just keeps them buried in his heart.
Naruto, who has just graduated early from the Ninja Academy and has little experience, has not yet experienced saving Konoha from Pain and gaining everyone's recognition.
Even now, Naruto is still striving to gain the villagers' approval.
Seeing Naruto instantly become dejected, the Dark Side pressed its advantage.
"Come on, kill me or merge with me, and you will gain unimaginable power, shut those fools up, and teach them respect!"
As he spoke, the Dark Side underwent a transformation, with crimson Chakra emanating from his entire body and tails appearing behind him, swaying slowly.
This is... Partial Tailed Beast Transformation!
Shisui and Guy are both Jonin, and Shisui even fought against Rōshi, so he instantly saw through Naruto's Dark Side and his current state.
That aura, filled with hatred and misfortune, was entirely the Nine-Tails Chakra.
Not only Shisui and Kai, but also the Nine-Tails, who was originally lying down with its eyes closed to rest inside the sealed space, now had its eyes wide open.
The most unbelievable one was none other than the Nine-Tails.
Using the Nine-Tails in the seal that Ren had once torn open, Kurama, with a look of utter disbelief, carefully sensed the presence of the outside world.
After a while, Nine-Tails seemed relieved, its expression becoming lazy again, and it lay down to rest with its eyes closed.
Pshaw, it's fake!
Naruto glanced at the Dark Side that could skillfully wield the Nine-Tails' power, and a fleeting thought crossed his mind. Mastering the Nine-Tails' power was his purpose for this trip.
However, Naruto is Naruto after all. In the original work, he was able to become the perfect Nine-Tails Jinchuriki because of Jiraiya's three years of ideological education without teaching him any real skills, his own experience that shaped his maturity, and Killer B's unreserved teaching of everything he knew.
But all of these are just external factors. There are probably tens of thousands, if not tens of thousands, of people in the Shinobi World who possess these external factors, but there is only one Naruto.
There is only one true internal cause, and that is Naruto himself.
At this point, Naruto had indeed experienced nothing, but he possessed a trait that no one else in the Shinobi World had: extraordinary empathy.
It's impossible for people to truly empathize with each other, but people with strong empathy can feel sad for others' suffering and joy for others' growth.
Naruto spoke in a very sincere tone.
"It must have been tough!"
The previously unrestrained and arrogant expression on the Dark Side paused, and a look of confusion appeared on his face.
"I said, you must have worked very hard and suffered a lot to gain this power!"
Anger flashed across the Dark Side of his face. "What is this all about? Are you pitying me?"
But Naruto continued speaking as if he was completely oblivious.
"That's true. After all, you are me, experiencing everything I've experienced inside me. I know exactly what that heartache feels like."
With that, Naruto voluntarily walked towards his Dark Side.
"I'm sorry for making you suffer all this, but you won't blame me, after all, you are me."
As he spoke, Naruto even gave a smile.
"I won't kill you, after all, you are me. As for merging with you, it doesn't need to be that complicated, we've always been together."
Naruto, who had already reached the figure in front of the Dark Side, did not stop but continued walking forward.
As Naruto drew ever closer, the Dark Side tried to retreat, but after taking a step, it pulled back.
Then the two Naruto gradually began to overlap, Dark Side gradually turned into fragments, merging with Naruto.
Standing still, Naruto silently sensed the changes within himself. The truth was not as the Dark Side claimed; Naruto had not mastered the Nine-Tails' power at all.
However, Naruto added in his mind.
Thank you for making me stronger and helping me get through the most difficult period of my life.
Naruto turned his head, smiling, and asked Shisui and Guy.
"Brother Shisui, and Teacher Thick Eyebrows, do I pass the test?"
Shisui and Guy were keeping a close eye on Naruto. When Naruto started walking down the Dark Side, Guy tried to stop him, but Shisui stopped him.
Shisui, who possessed the Flying Thunder God Technique, was confident that he could instantly take Naruto away when the incident occurred, but the Dark Side dissipated on its own afterward.
However, the two did not let their guard down until this moment, when Shisui's Mangekyō Sharingan slowly closed.
Afterwards, having gained experience, Shisui did not call Yugito Nii, and led Naruto and Guy across the Waterfall of Truth.
After traveling a long distance, the three arrived at the shrine where Utakata had become the Perfect Jinchuriki.
After a brief discussion, Naruto opened a brightly lit secret room, while Guy stood guard outside with the unconscious Kakashi.
After that, Shisui and Naruto went inside together.
