Uchiha, starting from the destruction of the ninja world

Kakashi's figure blurred into the misty fog as he wielded his short sword...

The trajectory traced by the blade gradually became tinged with confusion and bewilderment.

Kakashi's thoughts began to drift.

Many familiar faces, figures that had once warmed his life, appeared before his eyes one by one.

Sakumo Hatake, the White Fang of Konoha, a powerful ninja in his own eyes, was driven to suicide by the village due to issues with his mission and comrades...

The teacher, the Fourth Hokage Minato Namikaze, gave everything for the village and ultimately sacrificed himself in the Nine-Tails incident.

And Lin...

Those he cherished have all departed, leaving behind only lingering regret and longing.

The only thing that comforted him was that Obito was still alive.

Although Obito has become extreme, crazy, and even wants to heal his inner wounds by destroying the entire ninja world, Kakashi cannot feel any real hostility towards him.

Ultimately, Obito remained his closest friend.

They fought side by side and went through the most brutal years of the Third Shinobi World War together. They were important partners who entrusted each other with their lives.

For Kakashi, the softest part of his heart always held a place for Obito.

He didn't agree with Obito's actions, but he couldn't bring himself to stop him, and even had a vague desire to stay with him.

But the thought of this overwhelmed Kakashi with a strong sense of guilt...

If the ninja world is truly destroyed because of Obito's madness, then am I also an accomplice, or even the culprit?

At this moment, Kakashi's swordplay became increasingly chaotic...

It was so chaotic that even Obito noticed something was wrong...

What happened to Kakashi...?

The blade reflected the fine, icy mist, making it appear even colder and more bewildering.

The instant he landed, Kakashi let out a soft sigh...

His gaze gradually dimmed: "Teacher...have I disappointed you?"

"But I need to protect Obito..."

Protect the soil belt...

Upon hearing this, Obito's expression in the shadows became even more complex...

That bastard, why does he talk so mushyly...?

Hey...

However, at this moment, Kakashi seemed to remember something...

His teacher, Minato Namikaze, once had a child.

Naruto Uzumaki, the child born on the night of the Nine-Tails.

That was a child who, from the moment of birth, was destined to bear the fate of a Jinchūriki.

Over the years, after the teacher and his wife passed away, the child's situation...

Why didn't I care about that myself?

perhaps...

It's because my past self was unwilling to face these things...

Kakashi deliberately ignored this fact because he was unwilling to touch upon this painful memory.

But at this moment, when he thought of Naruto's existence again, a strong and uncontrollable desire suddenly surged in his heart.

past...

Naruto was completely ignored...

I really should try to find out more about this child's life.

Kakashi wanted to know how this child, who carried all of his teacher's hopes, was doing now.

Did he inherit his teacher's optimistic and positive personality, or did he become gloomy and depressed due to the village's lack of understanding and isolation?

Once this intense desire arose, it spread rapidly like wildfire, making it impossible for Kakashi to suppress his inner impulses.

He quickly made a decision...

Go and pay attention to Naruto personally, observe him closely and learn everything about him.

"Naruto..."

He slowly sheathed his short sword, stood at the edge of the waterfall, and let the mist gently patter on his cheeks.

"Kakashi, I didn't expect you to use a sword again."

A deep, slightly hoarse voice suddenly sounded from behind, interrupting Kakashi's chaotic thoughts.

"Obito..."

Obito stood quietly in place, his mask obscuring most of his expression, but the one eye that was visible revealed a depth and turmoil completely different from before.

He gazed at Kakashi, who held a short sword, a hint of nostalgia and guilt flickering in his eyes.

While Kakashi was practicing his swordsmanship, Obito had already been secretly observing him from the shadows for a long time.

Watching Kakashi's skillful and fluid swordsmanship, his memories instantly returned to his childhood.

At that time, Kakashi was young and proud, a genius of Konoha, with superb swordsmanship and unparalleled control over chakra.

In Obito's eyes, Kakashi just now seemed to have regained his former spirited and vigorous appearance.

But then, his heart was filled with deep self-blame and guilt.

Kakashi had previously spoken to himself, seemingly protecting his own words...

This deeply wounded Obito's heart.

After a moment of silence, Obito finally spoke with difficulty: "Kakashi, actually... there's something else I've never told you."

"What is it?"

"I was the one who orchestrated the Nine-Tailed Night back then."

Upon hearing this, Kakashi's pupils contracted sharply, and the short sword in his hand trembled slightly.

"Obito, you..."

Kakashi's voice choked with emotion, his heart churning with feelings he couldn't express.

In fact, when Obito reappeared before him after his resurrection, Kakashi had a vague suspicion...

However, to everyone's surprise, Obito took the initiative to admit it this time.

Obito's voice grew even hoarseer, filled with deep self-reproach and heaviness: "My teacher, and his wife... they all died because of my stupidity."

"They could have lived happy and peaceful lives, Naruto should have had his parents... I caused all of this. Will you blame me, Kakashi?"

After a long silence, Kakashi sighed softly, a faint bitterness and relief showing on his face.

Kakashi walked up to Obito and gazed at his childhood friend.

"Obito, since you didn't blame me for Rin's death back then, how could I possibly blame you for what happened to our teacher?"

"Just as you said, the root of all the tragedies lies in this ninja world shrouded in hatred and distortion."

"This knife... has been silent for too long... but now, for you, it can dance once more..."

As Kakashi spoke, the Sharingan powers of the two began to resonate intensely...

Sharingan...

Because of strong emotions, they become stronger...

"Kakashi, you..."

Obito stared in surprise at his best friend, feeling a surge of emotion and guilt.

He originally thought Kakashi would hate him, even despise him, because of this...

Unexpectedly, I received such a reply at this moment, and my heart was filled with a long-lost warmth.

Kakashi slowly sheathed the short sword back into his waistband, his gaze gently fixed on Obito.

"Obito, we can't undo what happened in the past. But we can choose what to do next."

"I've decided to go see Naruto, the boy my teacher entrusts all his hopes to. Obito, would you like to come with me?"

Obito was suddenly struck by a jolt. He had never expected that hearing such a promise again after so many years would move him so deeply.

No matter how obsessive and crazy he was, in Kakashi's eyes, he would always be the close friend who had fought alongside him.

"Thank you, Kakashi."

Obito uttered only one sentence in the end, yet it contained endless emotion and remorse.

"However... I'll leave the teacher's child in your care."

More than Naruto, Obito cared most about Sasuke...
