Time skip one year.

@ Uchiha District:

Itachi, age 5, approached his father, Fugaku, requesting more shuriken.

Fugaku agreed, impressed with Itachi's progress. He decided to teach Itachi the shadow clone jutsu, acknowledging that Itachi had mastered the basics of all three jutsus already.

Itachi hesitated, mentioning that the Nexus elders had classified the shadow clone jutsu as a B-rank Kinjutsu, requiring more chakra.

Fugaku reassured him, "You have enough chakra to make at least one clone."

Itachi eagerly learned the shadow clone jutsu from his father. After two hours of effort, he successfully created a shadow clone.

Fugaku praised Itachi's quick mastery of the forbidden ninjutsu, recognizing his exceptional talent.

Itachi then asked, "Am I close to Uchiha Ryu?"

Fugaku replied, "Well, Itachi, we still have a long way to go. Ryu is truly exceptional and stands apart from others."

From a young age, Itachi had been raised with constant comparisons to Uchiha Ryu, the official prodigy of the Uchiha clan, possessing remarkable abilities.

Ryu was known for

Being a tailed beast summoner like Uchiha Madara

The second fastest shinobi after the Fourth Hokage due to his Swift style,

Skilled in Uchiha Kenjutsu,

The earliest graduate from the Leaf Academy,

A war hero who captured Puppet Mistress Chiyo,

One of the disciples of the Fourth Hokage.

Itachi couldn't help but feel overwhelmed by Ryu's accomplishments.

He expressed, "I see why To-san always praises Ryu."

Fugaku explained further, "Not only that, Ryu is the one who came up with the idea of the Nexus and introduced successful business strategies to the Uchiha clan, significantly improving our financial situation. Thanks to his ideas, the living conditions of all clan members have improved."

Itachi developed a deep respect for Uchiha Ryu, understanding the positive impact he had on their clan.

Due to the compulsory attendance of the Nexus for all Uchiha children, Itachi gained more knowledge and dedicated time to practice Shurikenjutsu and ninjutsu.

The Nexus also played a crucial role in unlocking chakra for all clan children at the age of 3, nurturing their potential from a young age.

Itachi had been deeply affected by the trauma of the Third Ninja War, leading him to become a pacifist with a strong determination to put an end to wars by any means.

The next morning,

Mikoto said to Itachi, "I have kept a glass of milk on the table, make sure you drink it."

Itachi replied, "Yes."

Meanwhile, Fugaku was reading the newspaper.

Itachi expressed his desire, "To-san, instead of going to the Nexus, I'd like to practice throwing Shurikens today."

Fugaku responded, "In the storeroom, I have bought 30 Shurikens and 20 Kunai for you. Practice your throwing skills."

Itachi nodded and drank his milk before heading to the Uchiha forest training ground.

Meanwhile, one of Ryu's clones was assisting Shisui in mastering the Kenjutsu technique "Sun Halo," which allowed him to produce flames from his blade. Ryu's "Song of War" had gained an undeniable reputation for its crimson fire that prevented the slashed parts from healing or re-attaching.

Amidst their training, Ryu received a summons for a mission and headed to the Hokage's office.

At the Hokage's office:

Minato addressed Ryu, "Ryu, I want you to join the Anbu and provide support to Kakashi. Are you willing to take on this role?"

Ryu respectfully replied, "Yes, Hokage-sama."

Minato acknowledged, "Good. I understand recruiting someone into the Anbu at the age of 10 is unconventional, but your potential is exceptional."

Ryu respectfully said, "In that case, I have a request, Hokage-sama."

@ Uchiha District:

Itachi observed with awe as he recognized Shisui and Ryu practicing their techniques.

Shisui proposed a spar with Ryu, who clarified that he was just a clone, but Shisui insisted.

Both activated their respective Sharingan - Shisui with two tomoe and Ryu with three tomoe.

Shisui attacked Ryu with his iconic Fire Style: Fireball Jutsu, which impressed Ryu, noting its dense and powerful nature.

Ryu responded with his own Fire Style: Fire Dragon Jutsu, summoning a blue fire dragon that clashed with Shisui's fireball. Ryu then followed up with Wind Style: Violent Whirlwind, intensifying the collision.

Shisui swiftly flickered to evade the attack and attempted to strike Ryu's neck with his sword.

However, Ryu's three tomoe Sharingan gave him a significant advantage, allowing him to perceive Shisui's movements and react accordingly.

The clone of Ryu caught Shisui's wrist and held the sword to his neck in a swift and synchronized motion.

The intensity of the spar amazed Itachi, who watched with sweat dripping down his forehead.

Ryu, without turning to face Itachi, asked, "Are you Itachi Uchiha?"

Itachi apologized, saying, "I'm sorry for watching your spar without permission."

Ryu reassured him, saying, "It's okay, no problem."

Curious, Itachi approached Shisui and Ryu, questioning, "How did you know I was hiding? Because where I hid was a blind spot for both of you."

Itachi explained that the spot he hid in was a blind spot for both of them.

Ryu acknowledged Itachi's observation, remarking, "Wow, a five-year-old kid who knows about blind spots! You're pretty good, Itachi."

Shisui added, "Well, it can't be helped. Ryu is a very skilled sensor."

Itachi was surprised, exclaiming, "What? Ryu is also a sensor?"

Shisui grinned at the revelation.

Ryu asked Itachi, "What do you think about war?"

Itachi replied, "War is hell."

Ryu agreed, saying, "True, 'war is hell' is the correct way to put it."

Shisui added, "Yeah, we lost our parents in war too."

Itachi fell silent.

Ryu then said, "I thought there were classes today at Nexus."

Itachi confirmed, "Yes, I asked for To-san's permission to practice Shurikens today."

Shisui acknowledged, "I see."

Ryu requested, "Shisui, teach him. The Hokage is talking to me there, and I want to be dispelled."

Shisui agreed, saying, "Okay."

Itachi was surprised and asked, "Dispelled? Are you a shadow clone?"

Ryu answered, "Yes." *Poof*... the clone disappeared.

Shisui remarked, "Well, it's rare for him to ask someone to teach."

@ Hokage's Office:

Ryu: "Sensei, I want my rank to be increased to Jonin and to learn the Wind Vacuum Jutsu."

Hiruzen opens the door, "Wind Vacuum, you say!"

Ryu: "Yes, Lord Third."

Hiruzen: "Your contribution in capturing Chiyo during the war is enough to promote you to Jonin. It is possible now. However, the Wind Vacuum Jutsu is very powerful."

Ryu: "I'll make an exchange, offering my own A-ranked Purple Lightning Jutsu, which I created."

Minato: "Ryu, if I appoint you as a Jonin, will you join the Anbu?"

Ryu: "Sensei, you asked me to join the Anbu, so I will definitely do so. But this is a request, and you can deny it if you want."

Minato: "No, Ryu, you are capable of doing the work of four Jonins alone. So, what do you think, Lord Third?"

Hiruzen: "There's no problem in appointing Ryu as Jonin and having him join the Anbu, but the exchange for the Wind Vacuum Technique must be made. Ryu, show me the technique in the training ground now."

Ryu: "Yes, Lord Third."

Minato, Hiruzen, and Ryu proceeded to the Anbu grounds under the Hokage's supervision.

Ryu first demonstrated Chidori, transforming it into dense Purple Lightning.

In a single go, Ryu flawlessly executed the jutsu on five trees, proving it to be more effective and less hazardous than Chidori.

Hiruzen praised, "It seems your Purple Lightning is useful for cutting, piercing, and shocking. Well done, Ryu."

Ryu responded, "This jutsu doesn't require the insight of the Sharingan in battle, making it accessible to all Lightning release users."

Both Minato and Hiruzen were satisfied with Ryu's performance.

Minato then announced, "Ryu, your rank is raised to Jonin, and as a token of appreciation for your contributions, you can get the wind Vacuum technique in my office today evening."

Ryu gratefully replied, "Thank you, Hokage-sama."

Minato's genuine intentions towards Ryu were evident in his Eye of Mind.

Minato continued, "Ryu, you will be placed under direct control of the Anbu along with Kakashi."

Ryu nodded and said, "Yes, Sensei."

Minato instructed, "Meet at the ANBU headquarters at 7 PM."

Ryu acknowledged, "Hai."
