Naruto: This Uchiha is too innocent.

"Damn it! I almost hit you with my Fireball Jutsu!" Obito crossed his arms, his face full of resentment.

"Oh." Kakashi merely responded with a nonchalant "oh" to Obito's anger, an attitude that instantly irritated Obito.

"You don't believe me, do you?! You just don't believe me!"

"Believe me, believe me, you're right."

"Aaaaaah! Kakashi, I challenge you to a duel!"

"Alright, alright, we're all in the same class," Rin advised from the side, her face full of helplessness. She shook her head; she was at her wit's end with Obito, this childish guy.

She clearly had a chance to hit Kakashi just now, but this guy suddenly got carried away and didn't even look at her eyes.

Just as the two were bickering, she began searching for her teacher. Soon, she spotted the two sitting on a tree branch not far away. Her gaze lingered on the familiar boy's face for a moment, then a smile as beautiful as a flower bloomed on her face.

"Kong! What brings you here?"

Rin's shout immediately brought Kakashi and Obito back to reality from their "battle." Obito, in particular, looked up and saw Sora's face, his expression turning ashen as if he'd eaten feces. He muttered, "Why is this annoying guy here?"

As for Kakashi, he stared at Uchiha Sora for a long while before slowly looking away.

"Having nothing better to do today, I came to check on the results of your special training," Uchiha said, and he and Minato approached the three.

"Tch, if you have nothing better to do, go home and eat rice." Obito scoffed.

"Hehe, Obito, it seems you got thrashed by Kakashi again just now," Uchiha Sora teased.

"Abuse? Is that abuse? That's clearly a miscalculation!" Sure enough, Obito immediately panicked, turning his back and pointing at the Uchiha clan crest. "I'm going to be the Hokage someday! This is all a test for me!"

"Yes, yes, future Hokage." Uchiha Sora replied perfunctorily.

"Hey, what kind of tone is that? Let me tell you, I'm not the same person I was two weeks ago. Come on, let's have a go, and I'll teach you a lesson."

"oh."

Twenty breaths later...

Obito returned with a bruised and swollen face, while Uchiha Sora had only a slightly dirty hem of his clothes. It was clear who had won and who had lost.

"Not bad, not bad. In the past, it would have taken ten breaths to finish you off, but now it takes twenty. Your strength has indeed doubled." Uchiha Sora gave a thumbs up.

"Pfft."

Laughter erupted, and everyone looked at the instigator. Lin blushed and said, "I... I couldn't help it."

Obito's face darkened. He felt he had lost face again. Wait, why did he say "again"?

"If you're so capable, then don't use psychic abilities," he said angrily.

"I did not stop you from using summoning," Uchiha Sora replied calmly.

"you--!"

"Alright, alright, we're all friends, no need to take this seriously." Minato clapped his hands together, instantly suppressing the two.

Kakashi, standing to the side, looked at Uchiha Sora with a serious and solemn expression. He had just witnessed Uchiha Sora's battle with Obito.

He had one feeling: this guy had gotten stronger again.

"Huh? Kong, what's that box you're carrying?" Lin asked, patting the sword box.

Obito was taken aback, only then realizing that Uchiha Sora had been carrying a wooden box on his shoulder. His face darkened again, meaning that Uchiha Sora had defeated him in ten breaths while only having one hand.

"This is the sword case," Uchiha Sora explained, showing everyone the Kusanagi sword.

"Not bad, a fine sword." Minato tapped the blade with his finger and exclaimed in admiration.

"Hehe, of course, look who it belongs to." Uchiha Sora replied smugly.

"Alright, alright, you get cocky when you get a little help." Minato laughed and handed the Kusanagi sword back to him. "You should have something to talk to them about. I'll wait here."

As he spoke, he vanished instantly, leaving behind only a specially made kunai.

The remaining four looked at each other blankly for a while before Kakashi said in a deep voice, "Sora, you should be looking for Rin."

As he spoke, he prepared to leave the place.

"Hey, where are you going? We're classmates, can't I talk to you?" Uchiha Sora said helplessly, pulling him back.

"Looking for me?" Kakashi was taken aback. He hadn't interacted much with Uchiha Sora. Apart from being called up to the stage by their teacher at the Ninja Academy, they had hardly ever spent time alone together.

"Hmm," Uchiha Sora didn't explain much, and directly pulled Kakashi away to the side. Obito wanted to follow, but Rin stopped him.

The dense forest nearby was overgrown with weeds as tall as a person, enough to completely conceal the two boys.

"Is it really that mysterious?" Kakashi said helplessly.

"Hmm." Uchiha Sora's expression immediately turned serious, his eyes revealing a maturity beyond his years.

Under that serious gaze, Kakashi was taken aback for a moment, then realized that what was about to happen was important, and he also became serious.

"You speak, I'm listening."

Uchiha Sora nodded, licking his dry lips. "If Minato isn't around in the future, and your Team 7 encounters ninjas from Kirigakure, I hope you'll abandon the mission and stay by Rin's side. If possible, it would be best to just run away."

Kakashi: ? ? ?

He frowned. "What do you mean? What do you know?"

Uchiha Sora shook his head. "The literal meaning."

"Reason? From what you're saying, Lin seems to be in danger. What information do you have?"

"...I can't say."

Uchiha Sora was unsure of the extent of the butterfly effect his time travel would cause, so he didn't plan to interfere too much with the original history for the time being, at least... he wouldn't interfere too much with the Third Shinobi World War.

In the original story, Rin was captured by Kirigakure and forced to become the Three-Tails' jinchūriki, which led to her death.

He feared that if he interfered too much with the plot, the butterfly effect he caused would make him regret it. If something else happened in Kirigakure and the plot didn't go according to the original story, it would be terrible. So he only told Kakashi, because Kakashi was the closest person to Rin at the time.

Therefore, he will only step out from behind the scenes and onto the stage after the Third Shinobi World War has ended and he has ensured that those he cares about are safe and sound.

"I don't understand." Kakashi shook his head.

"You don't need to understand, and you must never tell anyone about this, not even Minato." Uchiha Sora stared intently at Kakashi.

Kakashi remained silent, lowering his eyes to assess the truthfulness of Uchiha Sora's words.

After a long silence, he spoke softly, "If what you say is true, then there's nothing to ask of me; you're stronger than me."

"...I can't say."

Uchiha Sora remained silent for a moment, then spoke again: "If you promise me, as a way of repaying you, I will help you during the most painful moment of your life in the future."

Obito's death was the most painful moment for Kakashi.

"Besides, I did all this for Rin, so it's a good thing for you," Uchiha Sora added.

"Please, Kakashi."

Upon hearing this, Kakashi was taken aback. In his memory, Uchiha Sora was an extremely arrogant person who had never asked anyone for a favor before. Now, however, he was asking a peer like him for a favor.

Looking up, he saw those deep, dark eyes, and for some reason, he sensed a plea in them.

for a long time,

"...I promise you."
