"It can be performed without eye contact, and it makes people act according to the subconscious mind planted by the caster unconsciously. The only disadvantage is that it requires a continuous supply of chakra?"
Seeing Shisui nod, Yun followed up, "Is the ability of this technique only known to the Fourth Hokage?"
Shisui shook his head slightly. "The Fourth Hokage's disciple, Hatake Kakashi, also knows. His eye played a big role in the incident a year ago."
Yun recalled Kakashi's experience. With the Fourth Hokage still around, it was unknown whether Danzo would have a chance to bewitch Kakashi.
"From now on, don't tell anyone about your Mangekyō Sharingan's ability. Even if the Konoha high-level officials ask, just push it all onto the Fourth Hokage."
None of the three people present were fools, and they quickly understood what Yun meant.
Fortunately, this ability still had a weakness. The continuous output of chakra was its flaw. And with the Byakugan, it would be easy to spot who was being controlled.
"Brother Shisui."
Itachi's voice sounded as the two-tomoe in his eyes slowly turned. "What happened a year ago… the enemy who was captured and taken to the Police Force… his identity still hasn't been found out?"
Shisui shook his head slightly. "The reason the enemy wore a mask was because his appearance was ruined. And because the Fourth Hokage really did have important matters that day, he and I didn't get around to interrogating the man until the next day."
"But you should know what happened next. The man was rescued just after the Fourth Hokage and I left the police station. And the Mangekyō that was handed over to Captain Fugaku for safekeeping the day before... became a fatal disaster."
As he spoke, Shisui looked at Itachi guiltily. "And that eye..."
His words were cut off by Itachi. "I know. But as the clan leader, it was natural to hand over the lost Sharingan to the clan head for safekeeping. Still... I need to know the identity of that man if I'm to find my father's murderer."
Yun scratched his head. A year ago, Obito's Akatsuki shouldn't have had many members. He wasn't sure if the original Akatsuki had already gone rogue at that time.
But even if they had turned evil, would Nagato's Six Paths of Pain have come to rescue someone? Would Uchiha Madara be so shameless?
'Then... was it them?'
'Black and White Zetsu?'
The atmosphere grew tense for a moment as Itachi mentioned revenge for his father's death, until Shisui pulled out a ninja tool bag and tossed it to Itachi.
"A gift to congratulate you on your admission. This is a custom-made ninja tool from Granny Cat. The kunai is light and sharp—should suit you well."
Itachi looked at the tools inside the bag and, for the first time, smiled. "Thank you."
Shisui nodded and looked at Yun. Then he tossed him a scroll. "There are Shadow Clone and Body Flicker techniques in it, along with some Uchiha Fire-style ninjutsu. You're different from Itachi. I think you'll need these."
Yun took the scroll. As expected, Shisui really did understand him.
It didn't matter whether he could use Fire-style techniques or not, but the Shadow Clone was essential—for skipping class.
And there was also the forbidden technique, Multiple Shadow Clone Jutsu—Naruto's ultimate training cheat code. As long as you could endure it, you could infinitely stack experience.
And if you couldn't?
Brain death.
"Both Shadow Clone and Body Flicker require sufficient chakra. If you use them carelessly, no one will be there to save you. So..."
Shisui gave a reminder, then said, "That's it for today. Yun, take Izumi's wooden kunai back with you."
…
After the three separated from the training grounds and returned to the Uchiha district, Yun stopped halfway.
"You can actually sense me?"
Shisui was a little surprised when he suddenly appeared. But Yun simply shook his head. "Not sensed. I just guessed you had something more to say… something you didn't want Itachi to hear."
"Hah…"
Shisui let out a soft sigh, his voice filled with emotion. "Sometimes you really don't seem like a six-year-old child. Though I know ninja mature quickly—Kakashi graduated at five and became a Chūnin at six—but Yun, you sometimes act like a child and other times like an old man."
"Want to call me Grandpa?"
*Pah!*
Yun was slapped mid-joke. Shisui smiled. "That kind of joke is a bit too much."
Yun grinned. "So, what didn't you say earlier? Go ahead—I might be able to help you think of a solution."
After a moment of silence, Shisui's expression gradually turned serious. Even the three-tomoe in his eyes began to connect—his Mangekyō Sharingan was already activated.
Using both Mangekyō insight and a perception technique, Shisui checked their surroundings before speaking.
"The Kotoamatsukami I mentioned earlier is just the technique of my right eye. The left eye also has Kotoamatsukami, but its ability..."
There was no need for eye contact. No need to maintain a chakra connection. The target would be controlled unconsciously.
This ability, a total cheat code, was Shisui's ultimate genjutsu—Kotoamatsukami.
"When I first awakened my eyes, the technique activated on its own. That enemy… he committed suicide in deep remorse!"
Shisui's voice carried a deep unease. "From that moment, I knew how terrifying Kotoamatsukami was. Because of that, it takes several years for it to recharge once used."
Yun tilted his head. "So when's the next time it can be used?"
"Next year. There's still one year left."
Yun let out a breath of relief. 'Thank goodness it wasn't five years. If it had taken that long… the Uchiha might have been finished already.'
"This technique... don't mention it to anyone else. Not even in passing. If a third person finds out—"
He paused.
"That might be the moment the Uchiha clan is exterminated."
After those heavy words, Yun looked toward the Hokage building in the center of the village.
"Politics has been stained with blood since the moment we were born into this world. Don't test a superior's kindness with sincerity. Once they weigh the pros and cons, the outcome will never be in your favor."
Shisui nodded solemnly. "I understood the horror of this technique from the moment I awakened it. Yun, you're the only person besides me who knows. And I suspect you already figured it out even before I told you."
Yun looked at Shisui with sudden intensity, then glanced down. After a moment of thought, he looked up again.
There was no need for direct eye contact.
It didn't matter whether he looked or not.
Every memory of the past half year flashed across his mind—every conversation, every moment spent together.
'We can't underestimate anyone who becomes a Jōnin.'
Analyzing intel, evaluating every word—these were basic skills for a Jōnin.
And for someone like Shisui, an elite among Jōnin, nothing more needed to be said.
"Even though I won't ask about your secret, I can tell that you really like life here in Konoha. And unlike Itachi, you seem to care deeply for the ordinary members of the Uchiha clan."
As Shisui spoke, he glanced toward a small shop ahead. It was opened by a middle-aged couple from the clan—Uchiha Pancake Shop.
The owners were Uchiha Jing and Uchiha Tesho. Civilians—nothing more, nothing less—but kind to everyone.
Before Yun turned five, when only his mother was working to support the household, the two of them often gave pancakes to Yun and Izumi.
"They're just ordinary people. Yet because of the Uchiha name, their lives could be decided by others. Shisui..."
Yun turned to face him, his voice calm yet filled with conviction.
"Use your ability. Become the clan leader after you recover."
