Natsuri, who was in class, was led out of the classroom by her teacher and, after many turns, arrived at a relatively secluded area.
Looking at the room covered in seals, Natsuri was a little confused, wondering if this teacher had some strange habit.
"Go in, Natsuri-chan."
What puzzled Natsuri was that the teacher merely stood at the door, telling Natsuri to enter, but showed no intention of going in himself.
"Alright, Teacher!"
Natsuri didn't hesitate too much and walked in. After all, this was the Ninja Academy, what was there to be afraid of?
After entering, Natsuri saw the person inside: it was her older brother, Uchiha Tomoki.
Yuuki sat on a chair, expressionless, with his Mangekyo Sharingan activated, looking at Natsuri with an gaze full of scrutiny and coldness.
His younger sister, whom he had raised and doted on since childhood, had been tampered with; how could Yuuki be in a good mood?
As for Natsuri herself being the problem, and everything being an act?
Yuuki had considered that possibility, but for her to act so naturally, without him, an idol and a powerful Ninja, detecting any traces, the probability was infinitely close to zero.
"What is it, Big Brother? So it was you. I thought it would be some strange guy!"
Natsuri relaxed when she saw Yuuki, but then immediately noticed something was off.
Big Brother's expression and eyes were terrifying, and it wasn't an act!
Noticing that Yuuki was different from usual, Natsuri asked with some concern,
"Big Brother, did something happen these past few days you were away? Are you alright?"
Although Yuuki looked a bit fierce, Natsuri was still worried about him, as she had never seen Yuuki like this before.
Yuuki's Mangekyo Sharingan meticulously observed every detail, and Shinatsuhiko constantly monitored Natsuri's every heartbeat and every breath.
No discoveries, no flaws. This was Natsuri, his younger sister.
Except for that damned problematic Chakra!
Yuuki didn't intend to give up. His eyes turned incredibly cold, and his tone became equally detached.
"You are not Natsuri. Tell me, who are you!?"
Yuuki's cold expression, the obvious hostility and wariness in his eyes, and his icy words pierced Natsuri's heart like a sharp sword.
Why?
Natsuri's eyes turned red, and her heart was filled with grief and indignation. The intense emotions stimulated her brain, and the Sharingan in her eyes activated automatically.
A single tomoe looked plain and unbalanced.
However, immediately after, the tomoe quickly spun.
In less than a second, three tomoe appeared directly in Natsuri's eyes.
Eerie and enchanting, they possessed a unique and mysterious beauty.
An achievement that most Uchiha clan members could not attain in their entire lives, Natsuri had reached it at eleven years old.
From Yuuki's perspective,
After he finished speaking, Natsuri's heart pounded violently, and her breathing became rapid.
Yuuki didn't know if it was because he had uncovered a secret or because Natsuri was too sad.
If only looking at Natsuri's expression and eyes, it was indeed due to sadness.
But at the same time, the surge in Natsuri's Chakra, which increased significantly, occurred almost simultaneously with the change in Natsuri's expression, even before the Sharingan evolved.
The sudden surge in Chakra did not cause any burden to Natsuri's body, and Yuuki did not see any other Chakra being injected.
Three tomoe, huh? This shouldn't be your limit, Natsuri.
Natsuri, with her three-tomoe Sharingan, stared intently at Yuuki. Yes, the person in front of her was her brother.
This left Natsuri's mind in turmoil. The rapid increase in her ocular power and the surge in Chakra did not make Natsuri, unlike other Uchiha clan members,
become arrogant and self-important, immersed in her newfound strength. It did not affect Natsuri's thinking.
"Big Brother, what exactly happened to you? What exactly happened these past few days you were away?"
Natsuri's tone was filled with confusion, but her eyes showed more concern.
Yuuki remained silent, his expression unchanged.
Seeing Yuuki like this, Natsuri spoke again.
"Big Brother, when I was little, I was so mischievous but still so happy, unlike Naruto. I know it's all because of you, because you shielded our family, the Uchiha Clan, and even Konoha from all the hardships."
"Every time you came home late at night, every time you went on a long trip, not only Mom and Dad worried, but I worried about you too. Especially after starting school, I learned about the cruelty of the Ninja world. Thank you for everything you've done, Big Brother!"
As Natsuri spoke, the tears in her eyes could no longer be held back, and two streams of tears flowed down her cheeks.
"Tell me, what happened to make you like this!"
Natsuri wiped her eyes with her sleeve, stopping the tears, and spoke again, though her voice carried a hint of a sob.
"I'm not a child anymore. If I wanted to, I could apply for early graduation at any time. I'm also a qualified Ninja now. Things you can't tell Mom and Dad, you can tell me, Big Brother!"
After speaking, Natsuri continued to weep, but her eyes became resolute.
No matter the reason, Big Brother, I must make you return to your old self. Mom and Dad wouldn't want to see you like this!
Hmm, logical and reasonable.
But that itself was the most unreasonable part.
Yuuki had also experienced the feeling of a sudden surge in power, like when he killed Danzo or annihilated the Kumogakure forces.
The surging power made Yuuki feel as if he could pierce the heavens. If it weren't for years of habit making Yuuki unconsciously focus on expression management,
Yuuki would probably have looked up, closed his eyes, and laughed heartily. That feeling of a sudden, significant increase in strength was truly exhilarating.
Then, I'm sorry, Natsuri!
"Still trying to argue? Everything about you is exposed before these eyes of mine!"
Yuuki slowly stood up, his ocular power began to gather in his Sharingan, and he cast a genjutsu on Natsuri.
Hmm, no effect!
Unexpected, yet within reason.
Yuuki's ocular power had just stirred Natsuri's Chakra when it was extinguished by the transparent Chakra surrounding Natsuri.
This was a Mangekyo Sharingan genjutsu.
Although it had no effect, Natsuri was not entirely unaware. She clearly felt the reduction in her Chakra.
Big Brother just… was he attacking me?
Natsuri's heart churned. Yuuki's familiar yet strange appearance was deeply etched into Natsuri's eyes.
"Why, Big Brother, are you… are you trying to kill… me…?"
Seeing Natsuri's expression turn ashen and her eyes dim, as if her heart had died,
Yuuki also felt terrible. Continuously casting genjutsu on himself to maintain his expression and tone, Yuuki spoke again.
"You are not Natsuri. Don't call me Big Brother anymore. To refuse to admit it even until death, I have to admire you. Die!"
A fist-sized fireball shot towards Natsuri's head.
Natsuri watched the fireball grow larger in her vision, making no move, just staring blankly.
Big Brother, I don't know why you've become like this, but you think it's my fault.
Then kill me. I hope you can return to normal afterwards!
Is this what it means to be a Ninja? Rather than dying by someone else's hand, dying by Big Brother's hand is surprisingly not bad!
Natsuri looked straight ahead, past the fireball, staring intently at Yuuki, that familiar yet strange figure.
There was no fear of death in her eyes, but rather admiration, gratitude, and finally, only boundless love for her dearest relative.
Big Brother, no matter what you become, I will always love you!
