Deep in the Konoha forest.
Zephyr was currently tormenting a giant wild boar, while a young man watched from a tree not far away.
This young man was none other than Uchiha Itachi.
Uchiha Itachi was still somewhat curious; after sending Sasuke out of the forest, he had returned to this spot.
He clearly saw how Naruto, Lee, and Naruto's Shadow Clone dealt with the wild boar and how they roasted it.
The only thing that puzzled Uchiha Itachi was Naruto's Shadow Clone.
This time, when roasting the wild boar, the leading role was not Naruto's main body, but the Shadow Clone.
Moreover, he could sense a distinct difference in temperament between Naruto's Shadow Clone and his main body.
Uchiha Itachi's first reaction was the same as Lee's: Naruto suffered from multiple personality disorder.
Compared to Lee, Itachi understood multiple personality disorder better.
After all, he had experienced war, and after the war, many mentally fragile Ninja would suffer from a certain degree of mental illness.
Multiple personality disorder was one of them, especially for Ninja who liked to use Shadow Clone; this type of Ninja could even fantasize about various personalities, which was quite miraculous.
However, this was the first time Uchiha Itachi had seen personalities derived from multiple personality disorder actually increase combat power.
It was precisely because he wanted to test Naruto that he had lured the previous giant wild boar over.
However, what Itachi didn't expect was that it wasn't Clone Naruto who made the move, but the main body Naruto.
But from the aura and eyes, Itachi knew that the main body Naruto had been replaced by Clone Naruto.
Besides that, what surprised Itachi was Naruto's physical techniques.
Soru, Tekkai, Shigan—these were all pure physical techniques, in addition to the black substance covering Naruto's entire body.
Itachi, with his Sharingan, could easily analyze these three skills, but it was almost impossible for him to use them; these three physical techniques practically didn't use any Chakra, they were pure physical techniques.
Zephyr, who was fighting the wild boar and teaching at the same time, naturally sensed Uchiha Itachi's presence with his Observation Haki.
Zephyr never thought of concealing his existence, because he had to train Naruto continuously, and sooner or later he would be noticed by Konoha's higher-ups.
Instead of training stealthily, it was better to train openly; if the Third Hokage asked anything, he could simply say that Naruto had multiple personality disorder.
As for how Naruto got multiple personality disorder, the Third Hokage should know in his heart.
Naruto, who had no friends since childhood, was disliked by the villagers, and could only hide at home; it shouldn't be too much for him to fantasize about one or two good friends, right?
In the arena.
Zephyr's several Shigan instantly infuriated the wild boar.
With bloodshot eyes, the wild boar charged at Zephyr again.
Zephyr, on the other hand, calmly continued to explain, "This move is 'Kami-e' from the Six Styles."
As he spoke, Zephyr's figure swayed like a blade of grass in the wind; no matter how the wild boar attacked, it couldn't hit him.
After letting the attacks continue for more than ten seconds, Zephyr used Soru again to put some distance between himself and the wild boar.
"Next is 'Rankyaku' from the Six Styles."
As he spoke, Zephyr kicked fiercely in the direction of the wild boar, and then a blue flying slash cut into the wild boar's body.
This slash directly created a deep, bone-exposing gash on the wild boar's flank.
"Roar, roar, roar!"
The pain made the wild boar let out roars of anger, but this time, the wild boar did not continue to charge at Zephyr, but turned and ran.
This wild boar, having grown so large, was not unintelligent; after a few exchanges, it knew that Zephyr was someone it couldn't afford to provoke.
Seeing the wild boar trying to escape, Zephyr smiled, "Next is 'Moonwalk' from the Six Styles."
Immediately, Zephyr stomped on the air with his feet and chased after the wild boar.
In mid-air, Zephyr delivered another Rankyaku kick.
This Rankyaku directly struck the wild boar's neck, cleanly severing its head.
Witnessing Zephyr demonstrate all of the Six Styles, Lee's mouth practically never closed.
It wasn't until Zephyr had completely killed the wild boar that Lee finally came back to his senses.
"Zephyr-sensei, is this the physical technique you're going to teach us? So strong, truly so strong!"
Zephyr carried the wild boar's headless corpse over to Lee and Naruto, smiling.
"The Six Styles are just the basics. Once you've mastered the Six Styles, I have even more powerful things to teach you!"
As he spoke, Zephyr also showed off his pitch-black skin, which was Armament Haki.
"By the way… Zephyr-sensei, we're done fighting, why haven't you released your Haki? Doesn't Haki cost anything?!"
Hearing Naruto's question, Zephyr shook his head and said, "You'll know in a bit!"
Just like that, Zephyr carried the giant wild boar's corpse and led Lee and Naruto out of the forest.
However, before leaving the forest, Zephyr looked back at Uchiha Itachi's position.
"Heh heh… It seems you discovered me long ago, didn't you?" Uchiha Itachi said with a smile from his perch on the tree branch.
Although he had witnessed the personality manifested by Naruto's multiple personality disorder, Itachi still didn't intend to go to the Third Hokage and tell him about it, due to Naruto's identity.
In Itachi's opinion, even if he didn't say anything, the Third Hokage would know sooner or later.
But… what Itachi didn't know was that the Third Hokage was still playing dating sims, and Danzo was tirelessly grinding dark souls iii; it would probably be some time before either of them learned about Naruto's current situation.
Although both of them would occasionally take time to handle official business, most of their time was spent playing games.
The Third Hokage played because he was empty, lonely, and cold, while Danzo played to surpass the Third Hokage and prove himself.
Aside from games, what Danzo cared about most was probably the Uchiha Clan, the reason being… he needed more Sharingan; he wanted to beat dark souls iii.
Returning home, Zephyr placed the wild boar's massive corpse on the open ground downstairs.
He then hurriedly went back into the house and immediately entered the treatment machine.
There was also a control panel inside the treatment machine; after setting everything up, Zephyr put on an oxygen mask, closed the treatment machine's hatch, and began filling it with water.
After doing all this, he finally released the full-body Armament Haki and his consciousness left Naruto's body.
Upon returning to the room, Naruto saw this scene, and, somewhat puzzled, his consciousness returned to his body.
The moment his consciousness returned to his body, he felt intense pain all over.
From his bones to his muscles, there was a tearing sensation of pain.
"Holy crap…"
Naruto cursed under his breath; he finally understood why Zephyr had been continuously using full-body Armament Haki.
If he had released the Armament Haki earlier, his body would probably have collapsed to the ground.
