Kakashi Masters All Elements, Rewrites the Ninja World for Rin!

Obito, in a trance, ignored Shisui's questioning.

With only Kakashi in his eyes, he staggered forward, not even noticing that he had passed straight through Shisui!

Just a few steps—yet it felt like crossing a lifetime.

Finally, Obito used all his strength to walk in front of Kakashi, slowly raised his trembling right hand, and was about to touch his body—

But Rin suddenly looked up, revealing a pair of dark, empty eyes, as if her soul had been drained. That look instantly pierced Obito's heart!

What a desperate expression that was...

Obito felt as if his heart had been pierced by a thousand arrows, as if he had fallen straight into hell!

In that moment, he felt his hands were no longer qualified to touch Kakashi's body.

Tick... tick...

Blood-red tears streamed from his scarlet eyes, splashing into blood-red blossoms in the puddles at his feet.

"What on earth did I do...?"

Stimulated by Rin's deadened gaze, Obito was forced to face reality. The illusion had ended. There was no more hiding.

No—there was still a way!

Just as despair swallowed him whole, a memory of Madara's words surged in his mind:

The strongest illusion—if successfully cast—could discard every ugly truth and give birth to a beautiful dream for all. Infinite Tsukuyomi!

Madara had said, in the world of Infinite Tsukuyomi, there would be no more conflict. Everyone would be at peace...

Even the dead could return.

Yes, if he cast that technique—Kakashi could come back to life. Rin could smile again.

They could return to Minato-sensei's class… back to those irreplaceable days.

"I'm sorry, Rin. I'll make up for my sins... with my own hands."

"Kakashi, I want to create a world with you!"

Obito whispered words only he could understand. His eyes grew more resolute.

"But before that... I'll personally send the bastards who killed Kakashi and Rin straight to hell!"

Swish!

The next second, Obito vanished—reappearing within the ranks of the Kaguya clan!

"Uooooooa...!"

"Wood Style: Hell's Chaos!!!"

With a thunderous roar, dozens of massive thorny trees erupted beneath the feet of the nearby Kaguya clan members.

The grotesque trees spiraled upward, instantly engulfing every shinobi they touched!

Like twisted iron maidens, they crushed and pierced all inside. Blood oozed from between the wooden thorns, dripping down to the mud below.

Moments later, over a dozen Kaguya warriors—renowned for their defense—were violently shredded, their screams fading into silence.

Everyone who witnessed the carnage felt their scalps go numb.

Such a death… worse than the instant deaths delivered by that Uchiha boy earlier.

At least that was clean. This... was slow. Horrific. Torturous.

But regret? Yeah—there was no medicine for that in this world.

Their nightmare had only just begun.

Meanwhile, Kakashi had used Earth Style to slip away into the woods. Hidden behind a thick tree trunk, he quietly observed the unfolding chaos—torn between action and patience.

Yes, he had sensed Obito's approach earlier.

Just in case, he had substituted himself with a Shadow Clone before contact. A textbook play from the Book of Paranoia.

And to make sure Rin, who knew him best, didn't catch on, he'd even thrown in a little psychological suggestion, subtly nudging her mind to fully accept that the clone was the real deal.

Because even though Shadow Clones could fool almost anyone—including, ironically, Ōtsutsuki Kaguya—someone as close as Rin might pick up on something... off.

Some twitch. Some pause. Some comment like: "You didn't make a sarcastic remark when we were in mortal danger—who are you?"

So yes—extra layers of prep. Always.

As for Rin's safety? Not a concern.

She bore the Flying Thunder God seal. The second anything seemed off, he'd blink to her side and clean up whatever mess was dumb enough to try something.

All according to plan.

Except... nothing had gone according to plan.

First, Obito attacked him out of nowhere, leaving him as confused as a genin in a politics lecture.

Then—bam!—Shisui's eyes changed too!

Kakashi's mind buzzed, but inside, he couldn't help a spark of glee. Score!

After all, the Mangekyō Sharingan—the "Eyes of Soul Reflection"—revealed the truth inside the heart. The powers born from it weren't random; they were mirrors of the wielder's deepest desires.

He'd set this trap hoping two things would happen:

One, get a peek at Madara's playbook.

Two, ensure Obito's Mangekyō didn't come with something... useless.

He'd always thought it'd be tragic if Obito unlocked Amaterasu instead of Kamui—after all, burning things is cool, but reality-warping intangibility and teleportation? That's S-rank flavor.

And Shisui unlocking his own Mangekyō too? Bonus round unlocked!

Yes—this wave... was profit.

Until, that is, he heard Obito whisper:

"Kakashi, I want to create a world with you!"

Kakashi blinked.

"...Okay, that was... intense."

He'd been working toward this moment for years.

From becoming Tsunade's apprentice, to learning medical ninjutsu with the trio, to having Rin master Ninja Art: Mitotic Regeneration—

All of it, just to change fate. To avoid Rin's death. To derail Madara's ticking time bomb.

And now, they were this close.

Obito had awakened his Mangekyō. He'd return to Madara, who was about to do his dramatic oxygen-mask villain exit.

Then, all Kakashi needed to do was beat the Nine-Tails Rebellion to the punch, track down Obito before the world burned, and seal away Black Zetsu like expired groceries.

The dominoes were aligned.

But when he saw Obito—utterly shattered, drenched in blood and madness—Kakashi hesitated.

Sure, if he left it alone now, the plan would likely work.

But what if it didn't?

What if, by the time he found Obito again, the guy had already crossed that line—committed some world-ending mistake?

Even if Kakashi intercepted him in time, what about the mental scars from weeks of despair and darkness?

Would he still be the same friend?

Obito had always treated him as his closest comrade...

If his earlier suffering had been just enough to awaken the eyes—that could be rationalized. Short-term pain, long-term gain.

But now?

This... this looked like the beginning of the end.

Kakashi clenched his fists.

This boy—this sunbeam of a kid who, like Rin and Guy, had welcomed him to this world with open arms—was breaking apart.

If Obito truly experienced everything Madara had planned, would he ever smile again?

And if he, Kakashi, let that happen... what was the difference between him and Danzo, the old ghoul he despised?

No...

Madara's end could wait.

He'd just train harder. Grow faster.

Because right now, all he wanted to do—

Was pull Obito back from the edge.

Before the world lost him forever.
