Naruto Law of the Devil

Being able to use excellent medical ninjutsu at such a young age, Yu, who was currently standing in front of the group, was undoubtedly the object of envy for all the orphans present.

"Hey! It's almost nine o'clock now!"

"You little rascals, why aren't you going to bed yet? And that new kid too!"

But before Yu could say anything, a stern voice echoed from inside.

A plump auntie and an elderly man with white hair and glasses were seen walking into the hall from the inner room.

They were dressed in the distinctive black kimono with white shoulder wraps of Konoha Orphanage, the two assistant directors of the orphanage, Keiri and Kanpu, who assisted Yakushi Nono.

"No need to look so scared..."

"Although they seem fierce, Aunt Keiri and Grandpa Kanpu are actually very kind people."

Seeing the young orphanage boy Kabuto, who seemed a bit frightened by the stern-looking auntie, Yu comforted him calmly.

In fact, those who chose to work at Konoha Orphanage without caring about salary and rewards were not bad people.

"I'm Yakushi Yu."

"I'm one year older than you, so just call me Yu."

After saying this, Yu didn't pay attention to the reaction of the Yakushi Kabuto in front of him and walked straight towards the sleeping quarters.

After all, after practicing with the Thread-Thread Fruit ability all day, Yu was feeling quite exhausted.

Using the Thread-Thread Fruit's power frequently had been a significant test of his stamina.

"Yakushi Yu, Yu..."

Staring blankly at Yu's departing figure, the young Kabuto muttered Yu's name.

"Does he... not like me?"

Kabuto had noticed the complex look in Yu's eyes when he had been watching him.

Although he was still young, the sharp and thoughtful Yakushi Kabuto had sensed that Yu's attitude towards him was different from the other children.

Of course, Kabuto had no way of knowing that, under normal circumstances and without any external interference, he would play a critical role in the future.

He would be the one to kill the most important person in his life, Yakushi Nono, with his own hands.

"Just like the plot's trajectory."

"Yakushi Kabuto has also appeared..."

Lying on the bed and looking at the ceiling, Yu's thoughts swirled in his mind.

At the moment he had confirmed Yakushi Kabuto's identity, he had almost used the Thread-Thread Fruit ability to cut off Kabuto's head. However, his rationality had made him forcibly suppress that impulse.

"But no matter what, I will protect Nono."

"I won't let the plot repeat itself... never!"

With a determined gaze, he clenched his fists, feeling the chakra and Thread-Thread Fruit's power surging within him.

After a whole day of intensive training, Yu finally closed his eyes and fell into a deep sleep...

Time passed quickly.

Two months flew by in the blink of an eye.

Soon, it was the day for the annual enrollment of the ninja academy in Konoha.

In these days, almost all the ninja families in Konoha were busy making arrangements for their children's enrollment.

Even though in the current era of the escalating Third Great Ninja War, being a ninja wasn't the most popular profession, it still came with high risks and high rewards.

Moreover, due to the wartime situation, the top brass of Konoha had mandated that every child from a ninja family must undergo ninja training and become a ninja to provide more combat power to the front lines.

For example, the renowned Konoha genius ninja Kakashi Hatake, who had graduated from the ninja academy at the age of six, was a product of this era.

Konoha's Back Mountain.

In a forest covered in lush greenery.

"Sizzle... Sizzle... Sizzle..."

Occasionally, there would be sounds resembling the cries of countless birds.

"Ox-Rabbit-Monkey..."

"The seal sequence is so simple; there's no reason for me not to complete this move!"

In front of him, Yu's hands formed three hand seals in an instant, and his chakra surged.

A bright blue-white lightning erupted from his palm, only to quickly disappear.

"Damn it! Why isn't it working yet?"

Yu, seeing his ninjutsu failing to activate, wore a dissatisfied expression on his young face.

Indeed, Yu was currently training in the Chidori technique!

This technique involved concentrating a large amount of chakra into one hand to create a high-speed thrust, which produced a distinctive attack sound resembling the cries of thousands of birds. It was an A-rank lightning release ninjutsu.

In the original story, it was created by Konoha's genius ninja Kakashi Hatake and had an advanced version known for cutting lightning called the S-rank technique, Raikiri.

As everyone knew, the hand seals for Chidori and Raikiri were 'Ox-Rabbit-Monkey,' a three-step sequence.

Yu had chosen to train in this challenging A-rank lightning release ninjutsu because his chakra was of the Water and Lightning nature, and it was a powerful and flashy technique.

However, after spending a month practicing this high-level ninjutsu, he had realized that mastering such an advanced and forbidden-level technique without guidance was a daunting task.

"After two months of training, your strength has improved dramatically."

"Your chakra has also reached the stage of a Genin. However, isn't it a bit too early for you to attempt such a difficult ninjutsu?"

Unexpectedly, the voice of the demon resounded in Yu's mind during this moment.

The demon had observed Yu's nearly masochistic training over the past two months.

"Shut up..."

However, Yu abruptly interrupted the demon's seductive voice.

"Watch closely!"

With a determined look in his amber-clear eyes, Yu continued to form hand seals with his hands, and a blinding blue-white lightning illuminated the entire forest.

Lightning Release: Chidori!

It sounded as if thousands of birds were crying out simultaneously.

In a dazzling display of blue-white lightning.

A highly condensed, raging electric current finally stabilized in Yu's left hand.

"Unbelievable..."

"You actually completed it?!"

Seeing Yu, whose chakra had just reached the level of a Genin, actually completing Chidori, an A-rank forbidden-level ninjutsu, the demon's usually lazy and indifferent tone now carried a hint of genuine surprise.

In the ninja world, ninjutsu could generally be categorized into six levels based on their difficulty:

E - Academy-level (e.g., Tracking Jutsu, Transformation Jutsu, Clone Jutsu) 

D - Genin-level (e.g., Earth Release: Decapitating Technique) 

C - Chunin-level (e.g., Fire Release: Great Fireball Technique, Spirit Transformation Technique) 

B - Jonin-level (e.g., Shadow Clone Jutsu, Fire Release: Great Dragon Fire Technique)

  A - Forbidden-level, High-Level Ninjutsu (These were usually classified as forbidden for two reasons: they either posed a direct threat to the user's life or their effects violated the laws of nature.)

  S - Secret Arts-Level (e.g., Reanimation Jutsu, Raikiri) Of course, there were other categories, such as Kekkei Genkai (Bloodline Limits), Kekkei Tota (Bloodline Combinations), and Kekkei Mora (Advanced Bloodlines), which combined various nature transformations in unique ways.

Now that Yu had completed Chidori, an A-rank forbidden-level ninjutsu, on his own after two months of intensive training, it was indeed a remarkable feat.
