There is a fundamental difference between the three-tomoe Sharingan and the Mangekyō.
The rampaging Wood Release cells in Danzō's newly grafted arm couldn't be suppressed by the Yin power of a mere three-tomoe Sharingan. He had only managed to barely balance the two through the sealing technique embedded in the heavy metal shackles.
Even so, his body was still under considerable backlash.
Now, however, after transplanting Shisui's Mangekyō into his right eye, he immediately felt an unprecedented sense of relief—like biting into an ice-cold watermelon on a scorching summer day.
At the same time, the seal greatly suppressed the side effects of the Sharingan.
Danzō carefully savored the interplay of these two immense powers. Right now, he felt completely charged—everyone else looked like fodder to him.
So what if Shisui of the Body Flicker had awakened the Mangekyō?
Hadn't he still fallen to Danzō's schemes?
So this was the so-called ultimate power of the Uchiha.
Nothing impressive.
Shisui spat out another mouthful of black blood, looking extremely weak.
He raised his hand, wiped the blood from the corner of his mouth, then seized the moment to swallow some antidote pills given to him by Makoto. His voice turned sharp with anger: "Uchiha Sōsuke, you lured me out here on purpose today, didn't you?"
Sōsuke didn't dare meet Shisui's remaining left eye.
"…I'm sorry, Shisui. I need your power."
"My power? So you've figured out my dōjutsu, have you? Who are you planning to use it on? The Hokage… or Makoto? And then what—are you going to stage a coup inside Konoha?"
Danzō spoke coldly, arrogance evident in his tone: "You don't need to know that. For the sake of Konoha, hand over your other eye as well."
The four of them attacked again.
This poison had been specially prepared for Shisui, yet he had proven far more resilient than expected—he still hadn't gone down.
Having adapted to the Mangekyō's power, Danzō decided to stop wasting time. He intended to seize the other eye as quickly as possible.
But they had underestimated Shisui's physical condition.
A ninja's body, strengthened by chakra, naturally has a higher resistance to toxins than that of ordinary people. And Shisui—after years of training enhanced by the dojo's white natural energy—was far stronger than his original timeline counterpart.
If not for the poison and being tricked by Izanagi, he wouldn't have ended up in such a dire state.
Facing the four attackers, Shisui pushed himself further, forcefully activating the third stage of Susanoo.
The originally green half-bodied chakra avatar became larger, now clad in a Karasu Tengu armor.
With a sweeping strike of the spiral sword in his right hand, he forced his enemies back, while his left hand released a string of magatama-shaped energy projectiles.
Susanoo: Yasaka Magatama!
The projectiles struck the ground and exploded, their thunderous blasts echoing across the wilderness and kicking up clouds of dust.
Unfortunately, due to Shisui's severe injuries, the energy he formed lacked cohesion. The explosions looked powerful, but were mostly for show—their destructive force was heavily dispersed.
Still, it was enough.
Taking advantage of the moment when Danzō and the others retreated to avoid the blasts, Shisui immediately dispelled Susanoo and fled the scene.
When the dust settled, all four of them were wounded—but not seriously.
"So this is the Uchiha's so-called divine power…"
Sōsuke's eyes were filled with envy. He, too, was an Uchiha, and he also possessed a three-tomoe Sharingan. But his age and talent were inferior to that of this gifted younger clansman. He couldn't find a way to awaken the Mangekyō at all.
There was no helping it.
Not all Uchiha were the same.
Some could awaken the Mangekyō in a surge of overwhelming emotion—
Others, no matter how furious they became… could only stay furious.
A Root ninja stepped forward and asked: "Danzō-sama, should we pursue him?"
Danzō subconsciously touched his newly acquired right eye.
"No need. Proceed with the original plan. Uchiha Sōsuke, return and gather your men immediately to assist me."
"Understood."
...
When Itachi entered the barrier range of the dojo, Makoto, who had been asleep, suddenly opened his eyes.
Soon, Itachi arrived outside his bedroom. Seeing the door open automatically and the lights already on inside, he stepped in.
"Itachi, coming here this late—what's the matter?"
"Senior Makoto, Uchiha Sōsuke suddenly left Konoha just now. Shisui-niisan has already followed him. I was worried something might happen, so I came to inform you."
"Is that so? Let me take a look."
Makoto activated his sensory ability.
Although his detection range now far exceeded what it used to be, the other side had clearly taken precautions, choosing a location far from Konoha.
But that didn't matter.
If wide-area sensing didn't work, he still had directional sensing.
He was familiar with Shisui's chakra—
And Shisui carried one of his Flying Thunder God kunai.
Makoto quickly detected the mark on Shisui moving at high speed.
In the forest, Shisui gritted his teeth and sprinted toward Konoha while enduring the intense agony of the poison ravaging his body. Suddenly, a figure appeared in front of him.
His vision was already starting to blur, but he recognized the person immediately.
"…Makoto, it's you."
"It is. We'll talk after we get back. The poison is too deep—you need treatment right now."
Makoto placed a hand on Shisui's shoulder. As he infused medical chakra into him, he activated the Flying Thunder God. In an instant, the two of them returned to the room.
After landing, Shisui dropped to one knee, weak, but still forced himself to speak: "Makoto… Danzō took my right eye… and he's joined forces with the hawkish faction within the clan. You need to stop them."
After hearing this, several Wood Release clones burst out from Makoto's body. The moment they appeared, they vanished from the room.
Shisui's dōjutsu was still Kotoamatsukami. After awakening it, he had told Makoto about it—and this so-called ultimate genjutsu had no effect on him.
The Mangekyō was a hax-type ability—
But Makoto was pure stats.
Only the two of them knew this, including the ability of Kotoamatsukami. Makoto had strictly forbidden him from telling anyone else.
Makoto himself could withstand it—but the people around him couldn't.
The Hayate Squad often stayed at the dojo, but their parents only visited occasionally. Most of the time, they still lived at home.
Danzō might very well target them—especially Makoto's parents.
"Don't worry. They won't be able to stir up anything. Do you have any last wishes?"
Shisui trusted his old friend's strength completely. Hearing that, he murmured: "Then… I'll leave everything to you, Makoto. I… have no regrets left."
After saying that, he could no longer hold on. His body tilted and collapsed to the ground, black, tainted blood continuously spilling from his mouth.
"Shisui-niisan!"
Itachi was startled. He rushed forward to check, and after confirming that Shisui was no longer breathing, he turned back in disbelief: "Makoto-senpai… Shisui-niisan, he…"
Makoto's lips twitched slightly.
"…I'm sorry, Itachi. The poison was too severe. He can't be saved."
"How is that possible? Even you, senpai…?"
Like Shisui, Itachi had absolute trust in Makoto—and he knew just how powerful Makoto's medical abilities were.
Which meant—Shisui was truly dead.
At the age of twelve, something inside Uchiha Itachi seemed to shatter.
A surge of overwhelming spiritual energy suddenly flooded into his eyes.
The three tomoe in his pupils began spinning violently, eventually transforming into a twisted, triangular shuriken pattern.
At that moment, he didn't even notice the change.
There was only one thought in his mind—
To torture Uchiha Sōsuke and his group, along with Shimura Danzō, to death. To burn their laughable ambitions to ashes.
"Itachi," Makoto said, "congratulations on awakening the Mangekyō Sharingan. As your senpai, my gift is a secret—what I just said was a lie. Step aside. I need to start treating Shisui."
"…What? Shisui-niisan isn't dead?"
For a moment, Itachi didn't know whether to laugh or cry. He raised both hands and covered his eyes.
He could already feel the change in his ocular power.
Now, he understood—
He had obtained the same power as Shisui.
But if the price had been Shisui's life, he would rather never have awakened the Mangekyō.
These truly were cursed eyes.
The frenzied urge to slaughter that had just surged through his mind left a deep impression—and filled him with fear. If he let that madness take over, he didn't know what kind of person he would become.
As Makoto treated Shisui, he spoke: "Itachi, don't let power control you. You must control it. Hold fast to the beliefs you've always upheld—don't let the power you gained at awakening twist you."
"Also, your physical condition isn't on Shisui's level. The Mangekyō's Yin nature is too strong for you right now—it's not a good thing. From here on, you'll need to train hard. Until your physical energy balances out with the Mangekyō, don't overuse it."
Itachi took several deep breaths.
When he opened his eyes again, the Mangekyō had already faded.
He knew Makoto was right. Even from that brief moment of activation, he could already feel a slight pressure in his eyes.
"I understand, Makoto-senpai. What should I do now?"
"Stay here. I'll handle it."
"No, Makoto-senpai… The Uchiha matter—let me, an Uchiha, handle it."
