My Sign-in System in Naruto

The only time Danzō had ever poured his emotions into someone was with Yamato.

But that very incident had led Yamato to awaken the Will of Fire at a critical moment, defying Danzō's orders and being absorbed into Hiruzen Sarutobi's direct Anbu forces.

This had reaffirmed Danzō's belief that the Root he led only needed to remain buried deep underground.

No names, no emotions.

No past, no need for a future.

Only the mission and loyalty to him.

Only such a Root was a good Root!

As for alliances and cooperation, they were ultimately false, filled with betrayal.

Danzō wanted Haru to be completely loyal to him, to erase his emotions, past, future, and the so-called Will of Fire that Hiruzen had been instilling in him for the past five years!

Thinking this, Danzō's resolve grew stronger. He grabbed the bandages covering his right eye and tore them off, revealing the eye he had always kept hidden in the darkness.

A blood-red pupil with three tomoe.

The Sharingan!

Haru frowned slightly, not expecting Danzō to immediately use his trump card.

The Mangekyō Sharingan he had stolen from Shisui... Kotoamatsukami!

With just one glance, it could invade the target's mind and alter their will.

Even the official description called it "a technique that turns anyone the user sees into their puppet!"

It was the strongest genjutsu in Naruto!

Many even joked that the reason Uchiha Itachi was so loyal to Konoha, even to the point of massacring his own clan, was because he had fallen victim to Shisui's Kotoamatsukami.

However, Danzō was too late. Haru now had immunity to genjutsu.

Whether it was Tsukuyomi or Kotoamatsukami, Haru had nothing to fear!

"Kotoamatsukami!"

With Danzō's roar, his right eye instantly transformed, upgrading from the three-tomoe state to the Mangekyō.

The strongest genjutsu was activated!

Danzō was filled with pride. Even Hiruzen Sarutobi didn't know about this Mangekyō Sharingan.

Naturally, he wouldn't have warned Haru to be careful.

In other words, the moment Danzō revealed this eye, any resistance would be futile.

Without exaggeration, even Danzō himself feared this terrifying power.

And yet, Uchiha Shisui had wanted to use such a precious ability to stop a mere coup?

What foolishness!

After confirming that he had activated Kotoamatsukami, Danzō raised his hand and pointed at Haru, speaking in a commanding tone.

"From this day forward, you will inherit the codename 'Tenzo' and serve me. You will assassinate the Third Hokage, Hiruzen Sarutobi!

"On the day I become the Fifth Hokage, you will act as the vanguard of Root, clearing all obstacles for me!

"I will be the Konoha bathed in sunlight, and you will be the Root buried deep underground!"

Danzō's voice was filled with authority as he laid out his new assassination plan.

The previous attempt had failed because of Kakashi's betrayal.

But Haru's trustworthiness and the power he possessed far surpassed Yamato's!

Especially his terrifying chakra reserves, which were over a hundred times greater than Kakashi's.

Even if Kakashi tried to stop him again, he would only die under Haru's Wood Release.

"Bring me Kakashi's Sharingan."

Danzō commanded once more.

This time, no one would be able to stop him.

'Shisui, do you see this?

This is the correct way to use Kotoamatsukami!'

However, just as Danzō was brimming with confidence, thinking he had no more enemies ahead, Haru couldn't help but cross his arms and look at him with a deadpan expression.

'Kotoamatsukami doesn't work on me. What should I do? Asking for a friend, it's kind of urgent.'

Oh well.

Haru shook his head helplessly, a wry smile forming on his lips.

Since Danzō had come to him with Kotoamatsukami, he couldn't be blamed for what happened next.

After all, neither the Third Hokage nor the other Konoha higher-ups knew that Danzō had stolen Shisui's Kotoamatsukami.

Even if Haru took it from him here, Danzō would have no choice but to swallow his bitterness in silence.

Most importantly, Danzō had made the first move.

He was the one who started it whether it was the assassination attempts or the genjutsu, Danzō had initiated everything.

Haru was merely defending himself, acting in self-defense.

And everyone knew that Danzō's strength was on par with the Third Hokage's. With the support of Root, even the greatest heroes of the ninja world would be no match for him.

Let alone someone like Haru, who wasn't even a genin.

Haru had been… truly terrified at the time!

Moreover, Danzō had only collected Sharingan eyes after the Uchiha massacre.

In other words, at this point in time, he didn't know forbidden techniques like Izanagi.

"Danzō, when did you get the illusion that you had used Kotoamatsukami?" Haru's lips curled into a smirk, this time one of disdain.

"You… what did you say?"

Instantly, Danzō's eyes widened, and he stood frozen in place.

He hadn't activated the Uchiha's strongest genjutsu, Kotoamatsukami?

No…

That's impossible.

Although Shisui had said it would take over a decade to use it again, Danzō had drastically reduced the cooldown time using Hashirama's cells.

He could use Kotoamatsukami, the strongest genjutsu!

But…

Why?

Why!

Why hadn't it worked?

Haru should have fallen under Kotoamatsukami, had his will altered, and become Danzō's slave.

A sense of foreboding washed over Danzō.

Had his genjutsu failed?

"Kotoamatsukami!"

Danzō shouted again, activating the power of his right eye.

But Haru remained standing there, mocking him with a look of utter disdain.

"Kotoamatsukami!"

"Kotoamatsukami!"

Danzō began to panic, repeatedly activating Kotoamatsukami, but the result was always the same.

Not only that, but his right eye began to ache intensely.

This was the side effect of forcibly using Kotoamatsukami.

"Damn it, how is this possible? I clearly activated Kotoamatsukami! You should be under my control, a puppet to fulfill my plans!"

"Want to know why, Danzō?"

Haru took a step forward, his aura overwhelming.

It wasn't that Kotoamatsukami hadn't been activated. It was that the reward from his Sign-in System was incredibly powerful, granting him immunity to genjutsu.

Whether it was Tsukuyomi or Kotoamatsukami, neither would have any effect on him.

Of course, Haru wouldn't reveal the truth to Danzō.

He spoke slowly, his voice low, like a master strategist who had everything under control.

"You only saw the second layer, and you thought I was on the first layer. But in reality, I'm on the fifth layer!"

As Haru's words fell, a massive surge of chakra erupted from his body.

The ceiling, walls, and floor began to crumble!
