In Naruto Universe, time travel to become Naruto's sister

Kojiro Tajiri is quite pleased with his new class of students.After all, there are many heirs of big families.Yume, Nara, Inuzuka, Yamanaka, Akimichi, and most importantly, Uchiha.It feels like all the big clans were born at the same time period.Naturally, Tajiri would not complain about this.He's actually pretty happy about it, and has a tinge of whining about why none of them had twins.It is a great honor to teach a class filled with a new generation of talent. Twenty years later, when these people have reached the top of their respective families, he will get a lot of bragging opportunities and great benefits.

Unfortunately, bad things follow.In his class there are actually the Demon Twins and their sidekick, the castaway daughter of the Hinata family.When he first saw these two would be in his class, he was rather disgusted and wished to throw them out, but no other class.After all, he wants nothing to do with the damn demon twins.However, he quickly changed his tune when an acquaintance said he would pay him if he could fix the two imps in class.How could he disagree?It's clearly a win-win situation for him.

Tajiri couldn't help laughing when he thought of the exam results that were due out today.It was a very simple test, and as he had predicted, it was easy for everyone to get a passing grade.Of course, this doesn't include the two demons he tested with illusion changes.They both scored zero points, which was obviously something he was going to laugh at them about.

As soon as he entered the teacher's office, he felt that the atmosphere was a bit weird, but he still decided not to let the atmosphere disturb him too much.He was about to say hello to a female colleague when her eyes suddenly turned to him with disgust on her face.

"Damn pervert."

She said these words, and then walked to her classroom.Naturally, Tajiri didn't know why he was insulted like this, he planned to write down the matter first, and then ask about the situation.As soon as he was about to sit on the seat, he saw a "shiny" magazine lying in the drawer. He quickly closed the drawer at a speed that even "Yellow Lightning" might be shocked, and glanced at the room. There were many eyes looking at him, full of contempt, and he couldn't help but flushed, angry, and embarrassed. Who the hell put that damn magazine there? Is anyone kidding me? Shit, my reputation is ruined and it looks like it's going to take a long time to save it.

For such a sudden situation, there was nothing he could do now, so he decided to ignore it and deal with it later.He has made up his mind to bring to justice those who played tricks on him.Unfortunately, he was too focused on the magazine events to notice the pins strewn across his chair.As soon as Tajiri sat down, he howled in pain and stood up again.This made his colleagues look at him even more strangely.Apart from his misbehavior, isn't this kid also out of his mind?

"Damn, someone must be messing with me behind my back. First the magazines, then the pins. Anyway, I'll look into these things after class. Now, I'll have a cup of coffee to calm my nerves, and then go to class. I can't wait to humiliate these two demons, because they are the only students who failed the test. Hmm? The coffee smells a bit weird. It doesn't matter. The important thing is that I have to report their zero eggs after class. I am in charge, how can I deliver the expired and spoiled coffee to the teacher's desk?

After drinking the coffee, Tajiri went back to his classroom even though it tasted a bit weird.Standing in front of the door, he sneered disdainfully.

What are you kidding?Chalk wipes on the door?A ninja would never be defeated by such childish traps.

Tajiri opened the classroom door confidently, and as soon as the chalk eraser fell, his hand easily caught it.He was about to brag that stuff like that wouldn't work with ninjas, but...

*splash all over face*
A piece of cake appeared out of nowhere and hit him directly in the face.Seeing this scene, the whole class burst into laughter.The contrast between seeing someone confidently grabbing a prank eraser and being hit with a cake was so hilarious that most people laughed.

On the other side, Tajiri was furious.He saw the whole class laughing at him, and he felt his authority shattered.He felt that from this moment on, these children would no longer respect him.He needs to restore his authority as soon as possible.He needs to find the culprit, show off the teacher's methods cleanly, and frighten these restless youngsters.

"Quiet! Who did this?"

Unfortunately, silence is nothing but silence.The students weren't trying to protect the prankster, the problem was, they didn't know who did it.The eraser seemed to appear out of thin air, and so did the cake.Even if they want to name names, they really don't know who did it.

Tajiri also noticed that no one seemed to know anything and could only grit his teeth angrily.He wiped his face as clean as he could before starting his lesson.

"I have already graded you. I have to say that I am quite disappointed with you guys. You can fail such a simple test. How can you be a ninja at this level. If you fail such a simple test, then I advise you to give up being a ninja from now on."

This sentence makes many people curious.Most of them had the same thought: who could fail such a simple test?Green Pond and Naruto on the other side almost laughed out loud.They thought that their meddling in the exam would cause some trouble for the teacher, but it was far beyond their expectations.After the twins made extensive revisions to the test papers, none of them actually passed the test.That means their teacher has just declared that everyone in this classroom is unworthy of being a ninja.

As soon as Tajiri handed out the test paper, he felt something in his stomach was about to gush out.He quickly found some excuses to leave the classroom, and then quickly went to find the bathroom.He didn't even pay attention to the faces of his students, who realized their teacher had just told them in such a serious tone that they were not worthy of being ninjas, and some of the children were even crying because their dreams were taken away.
