The Ultimate Rat In The World of Ninjas!

At eight o'clock in the morning, Iruka came to the classroom early. Today was the first day of teaching. He hoped to make a good impression on his students, and he was also setting an example, telling them not to develop the bad habit of being late.

There was still half an hour before class started, and sure enough, no one had come yet.

As soon as he put the textbook for today's lecture on the podium, he heard a slight breathing sound.

As a ninja, he instantly became alert! With a flick of his hand on his thigh, a kunai shimmering with cold light appeared in his hand.

'Who? Hiding in the classroom. Could it be that his target is a student?!'

Iruka looked at the empty classroom, but the breath in his ears was so clear.

Although this was the ninja academy, it was not ruled out that spies from other ninja villages had sneaked in to attack Konoha's flowers!

Iruka leaped forward, jumped onto the table, and was about to stab Kunai to see who dared to be so bold but seeing the figure in front of him made him stop.

And, the other party's eyes opened suddenly, which made even him, a Chūnin, feel a little threatened.

It seemed that if he didn't stop his actions, he would suffer some serious attack or even die!  

This sense of crisis actually made Iruka break out in cold sweat!

...

"Iruka-sensei? Were you going to kill me?"

Naruto looked at Iruka coldly, and the Chakra in his right hand kept gathering. As long as Iruka dared to make a move, Rasengan would gather in an instant and hit his head hard!

This was the power of Ninjutsu from the system! As long as the proficiency was enough and his chakra was enough, even if it was a Jōnin, if you take a Rasengan without any preparation, you would be seriously injured.

Fortunately, Naruto's strength improved rapidly. Although he had not yet mastered this powerful ninjutsu, Naruto's physical attributes had already broken through Genin and are close to Chūnin!

Therefore, when Iruka jumped onto the table, exuding killing intent, trying to stab him with kunai, the impact of the killing intent made Naruto wake up immediately, and Rasengan was also prepared.

This was the first time.

Since Naruto came to this world, it was the first time that he was targeted with such pure killing intent. The person in front of him really wanted to take his life.

Even if he was Umino Iruka, Naruto's teacher.

But, also because he was Iruka, Naruto could understand.

In his opinion, most of the people in this village were just idiots who followed others.

"Uh... no no no!"

Looking at Naruto's indifferent eyes, Iruka reacted instantly, retracted the kunai, and jumped off the table.

Even though he hated Naruto and even attributed the murder of his parents at the hands of a demon fox on the night of the Nine-Tails' attack on him, when he realized Naruto was his pupil, he had not lost his mind, to attack an ignorant child!

Especially when he also learned that Naruto's parents also died in that disaster, and he was alone since he was a child.

Iruka can empathize with this feeling.

"I have no intention of killing you. I was overly nervous because I heard faint breathing sounds after entering the classroom, and thought it was a spy who had infiltrated the Ninja academy and wanted to attack the students!"

Iruka quickly waved his hands at Naruto who stood up, explaining anxiously.

'This was my student! On the first day of formal class, I planned to leave a good impression!

In the end, I almost hurt him!'

At this moment, Iruka felt the darkness of life like never before...

"Is that so? There will be spies infiltrating even the ninja academy?"

Naruto did not relax his vigilance. Not only did the Chakra in his hand not disperse, but he was ready to take out the explosion tag at any time. If something went wrong, he would just use the 'Multiple explosion tag throwing Technique', and then leave!

As for the consequences of the subsequent movement, it was not something that he considered for the time being.

"I'm so sorry!!"

Iruka bowed ninety degrees to Naruto and apologized earnestly.

If Naruto didn't forgive him, he won't get up! 

To be fair, this matter was indeed his negligence.

It might be the first day of class, and he was too nervous, thinking that an enemy had sneaked in, completely ignoring that there might be students who come early.

"...A misunderstanding?"

Naruto looked at Iruka silently.

It seemed that it was indeed a misunderstanding. Although Iruka did hate him before he reconciled with the original Naruto, he had always treated Naruto as an ordinary student and a good teacher who was dedicated to his duties.

Not to mention trying to kill him.

Iruka remained to bow, seeing that Naruto didn't speak, he felt regretful, it seemed that he had frightened Naruto.

"Hm?"

Naruto, who opened Kagura's eyes, felt the students coming from outside one after another.

"Iruka-sensei, do you know why I'm sleeping here?"

"Why...why?" Iruka didn't get up but asked suspiciously.

"Because at six o'clock in the morning, there was no one on the street and it was very quiet."

"This…"

Iruka understood what Naruto wanted to say.

If there was no one, he would not suffer from other people's scrutinizing eyes.

"I forgive you, the students are coming soon, teacher, get ready for class," Naruto said coldly.

"Thank you! Nothing like this will happen again next time!"

Iruka assured Naruto earnestly.

"Yawn...it doesn't matter, I'm used to it."

"You..." Iruka paused, not knowing how to reply.

"Eh, Iruka-sensei, why are you here so early?"

Ino looked curiously at Iruka and Naruto standing at the back of the classroom.

It was the Ino-shika-cho trio.

"Huh? Naruto, you must have been discovered by sensei while you were sleeping."

Shikamaru scratched his head.

"Iruka-sensei saw that the class was about to start, and was waking me up."

Naruto sat on the chair, propped his chin with his right hand, and said lazily.

"Ahaha, that's right, well, get ready, the lecture will start in a few minutes."

Iruka blushed and walked back to the podium in embarrassment.

Fortunately, Naruto didn't poke him, otherwise, it would be a shame!

"Iruka-sensei is weird." Ino shook her head.

"Naruto, what time did you come?" Shikamaru sat beside him and asked curiously.

When he came here yesterday, he saw Naruto sleeping, and thought he was too lazy to attend the opening ceremony, but why was he so early today?

"Oh, maybe half past six."

"My God! I was still sleeping at half past six!"

Ino said in shock.

"Me too." Chōji nodded as he ate his breakfast.

"You idiot, you didn't wake up after seven o'clock! If we didn't call you, you would have been late!!"

Ino growled.

...

Iruka looked at Naruto who was chatting, regained his bearings, and then remembered the sense of crisis he felt at that time.

"Could it be Naruto? Impossible, he's just a kid who just entered the academy, could it be the Anbu arranged by the Third Hokage..."
