Uchiha Itachi wore a look of astonishment.
"Could this be the upgraded version of the Sharingan recorded in the clan archives... the Mangekyō Sharingan?"
"This is truly the Uchiha Clan's invincible Kekkei Genkai. Shisui, you really live up to your reputation as the clan's top genius."
"With such ocular jutsu, perhaps we can suppress that guy and stop him from committing any wrongdoings."
Hearing Itachi's words, Shisui felt a bit of bitterness in his heart. It wasn't just about being a genius; awakening the Mangekyō Sharingan required a price. It was a price he didn't want to recall right now.
He spoke slowly.
"That's right. This is the invincible eye recorded in the clan archives: the Mangekyō Sharingan."
His eyes spun, activating the three-tomoe Sharingan, which then spun again to transform into pupils shaped like a four-pointed pinwheel.
He then introduced the exclusive dōjutsu of his Mangekyō Sharingan to Itachi.
"My left eye possesses a technique that can unknowingly alter a person's ideology and consciousness. It has a permanent effect. I have named it Kotoamatsukami."
"The right eye also enhances the effects of genjutsu, but it is not permanent."
"So, if that Ryōsuke truly becomes uncontrollable, I will use these eyes to change his ideology and make him loyal to the Leaf Village."
Itachi's expression changed upon hearing this. He hadn't expected Shisui to possess such a terrifying technique.
It was worthy of being a Mangekyō Sharingan dōjutsu. If Kotoamatsukami were used on that crazed guy, it would certainly protect the peace of the Leaf Village.
The unhappiness of being suppressed by that guy for so long vanished.
The pressure had been immense recently because Itachi felt that even his own father was beginning to become fanatical about that man.
Itachi couldn't help but say with anticipation, "Brother Shisui, you really do have a way."
"Why not make a move on that guy right now?"
"My father seems to be listening to him more and more, and the radical faction within the clan, led by Uchiha Yatsushiro, also listens to him. As long as we unknowingly change him, it is very likely that we can bring about a reconciliation between the Uchiha Clan and the Leaf Village's higher-ups."
Shisui, however, said helplessly, "It is too early to use it now. There is no need to use it unless absolutely necessary. After all, the cooldown time for the left eye's Kotoamatsukami is as long as twenty years. It cannot be used lightly."
"Moreover, Ryōsuke has not shown any rebellious ambition yet."
Itachi felt it was necessary to deal with that guy sooner rather than later, but since Shisui had said so, they would just have to wait until the other party made a move. It wouldn't delay anything.
At this moment, Shisui asked, "Actually, before coming back, I went to see the Third Hokage. He asked me to have the clan hand over the Two-Tails Jinchūriki. I wonder what your father, Clan Head Fugaku, plans to do? Why did he refuse the Third Hokage's proposal?"
Uchiha Itachi said helplessly, "Actually, it wasn't my father who refused to hand over the Two-Tails Jinchūriki. It was that Uchiha Ryōsuke who wanted to claim her for himself. She is already locked up in his home."
"Perhaps that radical wants to control the Tailed Beast."
This was his biggest guess. Otherwise, why imprison something as dangerous as a Tailed Beast Jinchūriki?
Shisui also looked helpless. Itachi had just said that even Clan Head Fugaku listened to Ryōsuke's words. It seemed that even something as important as the Tailed Beast Jinchūriki had been left in Ryōsuke's hands.
He felt inexplicably worried. Did he really intend to control the Two-Tails Jinchūriki?
Thinking about it carefully, it shouldn't be possible. The Sharingan cannot control the Two-Tails Jinchūriki unless it is the Mangekyō Sharingan.
Only when the Sharingan has been upgraded to the Mangekyō Sharingan is it possible.
Because the process of upgrading to the Mangekyō Sharingan greatly increases pupil power and grants exclusive dōjutsu, controlling a Tailed Beast becomes entirely possible.
He shared his thoughts with Itachi.
Uchiha Itachi understood Shisui's meaning. So that was it.
It seemed that Ryōsuke, who had currently only opened the three-tomoe Sharingan, had no possibility of controlling the Jinchūriki.
Then what was this dangerous guy planning?
Why keep the Two-Tails Jinchūriki at home? He was truly an unfathomable guy.
Shisui then said, "It seems I have to go find this person myself. I must persuade him to give up the Tailed Beast Jinchūriki. Regardless of whether he wants to control the Tailed Beast or not, possessing a weapon of mass destruction at the level of a Tailed Beast will definitely make the village target the Uchiha Clan even more."
Itachi nodded in agreement.
After parting ways with Itachi, Shisui did not go directly to find Ryōsuke. Instead, he asked around the clan to get a good understanding of Ryōsuke and gain a comprehensive overview of him.
The reason for doing this was, of course, that Ryōsuke's changes were simply too great. It wasn't just an earth-shattering change in strength, but also an earth-shattering change in ideology.
Ryōsuke shouldn't have been considered a member of the radical faction before, and he wasn't very close to people like Uchiha Yatsushiro.
Realistically speaking, he was probably just a neutral party.
However, the news he obtained from the clansmen made him increasingly shocked. This person actually specialized in Taijutsu. He remembered that the other party's body wasn't originally that strong.
How could there be such a sudden change? And the fact that he cultivated the forbidden technique, the Eight Inner Gates, astonished him even more.
Naturally, Ryōsuke had a large share of the credit for the battle with the Mist Village, but Might Duy, who knew the Eight Inner Gates, was also not to be underestimated. It was precisely that display of astonishing strength—kicking four of the Seven Ninja Swordsmen of the Mist to death—that had been pivotal.
It had similarly shocked the Mist Village greatly, bringing an end to the decade-long border war with the Mist Village.
And he heard from clansmen who had been on the battlefield that Ryōsuke's Eight Inner Gates had been cultivated to an extremely high realm.
Such a person made him feel a great deal of pressure. Even though he had awakened the Mangekyō Sharingan, without using Kotoamatsukami, it was unlikely he could defeat the other party.
His Kotoamatsukami wasn't truly invincible either; the target had to be unaware and unguarded for him to change them. Otherwise, if the opponent was on guard and conscious of it, he would not be able to successfully alter their will.
Such results made him increasingly curious about this person.
