Background / History

Shisui’s departure and the chance for peace

At the Naka Shrine gathering, Itachi notices Shisui’s troubled expression after Yu secretly warns him about Danzo. Following Shisui’s escape from Root, the two meet outside Konoha. Shisui explains Danzo’s attempt to seize his eyes and asks Itachi to find the unidentified master whose warning saved him 24 27.

Before leaving to infiltrate Akatsuki, Shisui awakens Itachi’s Mangekyō Sharingan and entrusts him with a letter for Fugaku. Itachi promises to pursue the master as the clan’s remaining chance to avoid destruction 27.

Itachi delivers the letter and admits to Fugaku that Danzo has threatened Sasuke’s life to obtain his cooperation in exterminating the Uchiha. Without Shisui’s alternative, he believes he would have submitted. Fugaku instead proposes negotiations with Konoha, promises to calm the clan, and sends Itachi to deliver the proposal to Hiruzen 28.

Investigating Yu

Sasuke’s account of Yu learning basic ninjutsu immediately draws Itachi’s attention. After coaching Sasuke, Itachi attends the boys’ shuriken contest and examines Yu with his Sharingan. He identifies chakra reserves comparable to a jōnin’s and suspects the boy is concealing even more, but does not yet recognize him as Shisui’s mysterious master 28 29.

When Yu’s Great Fireball becomes an uncontrolled pillar of flame, Itachi recognizes that the boy has bypassed the safeguards of the Eight Gates. He directs Neji to strike Yu’s chakra points, then explains the incident to the crowd after Yu stops the technique 31.

That evening, Uchiha youths confront Itachi for watching the contest rather than attending to clan affairs. He defeats them and condemns their narrow attachment to clan identity and reputation. His distress activates his Mangekyō, revealing black bubbles of resentment that Sasuke cannot see 32.

The bubbles form a bat. Itachi’s kunai passes through it, and Amaterasu only disperses it briefly. After its sonic retaliation makes him hear the youths’ resentful thoughts, he deduces that someone is converting resentment into chakra constructs. He connects the technique to Shisui’s unseen benefactor 33.

During a later encounter, Itachi uses his Yin Release Crow Hunt Technique to synchronize briefly with a bat’s chakra. This reveals the caster’s general location in the Hyuga compound. He follows the moving source toward a private meeting 38.

Alliance with Yu

Itachi finds Yu in the woods east of Konoha and accepts that the child is the expert he had overlooked. He kneels and offers his life in exchange for the Uchiha’s protection, but Yu raises him and insists they discuss the crisis as equals 39.

Their discussion turns from individual enemies to structural reform. Itachi recognizes that withdrawing the Uchiha from the Military Police Force would merely transfer public resentment to other clans. Yu gives him a draft Konoha civil code defining offenses and sentencing standards for Fugaku to submit at the negotiations 39.

Yu then proposes that Itachi become Hokage by saving Konoha during a future crisis, predicted to occur within one to five years. Itachi reluctantly accepts this condition, along with keeping Yu’s identity and information secret—even from Fugaku—and helping him cook. He also warns that he would not accept Yu becoming another Danzo 40.

Yu’s vermilion pill allows Itachi to develop his Susanoo to its armored Crow Tengu form. The two reveal their Susanoo, exchange teasing remarks, and part on friendly terms. Itachi returns home confident that the Uchiha can be saved, but honors his promise not to identify Yu. He later accompanies Fugaku to the negotiations 41 42 50.

Appearance

• Hair: Wears his hair tied back, described as a ponytail and later as a braid 29 41.
• Clothing: Wears a thin black shirt while keeping watch on the Uchiha compound’s rooftop 38.
• Eyes: Uses both three-tomoe Sharingan and Mangekyō Sharingan; his active Mangekyō glows crimson during his nighttime vigil 27 32 38.
• Susanoo: Manifests a crimson upper-body avatar whose armored Crow Tengu form has glowing golden eyes 41.

Personality

Itachi is analytical and willing to revise his assumptions. He initially discounts Yu because the child does not match his image of an expert, then explicitly acknowledges how that preconception limited him. His investigation of the resentment bats combines observation, failed attacks, and chakra analysis rather than relying on a single explanation 33 38 39.

His desire to protect both Konoha and his family creates a severe conflict. He recognizes faults in the Uchiha as well as the village leadership, opposes a rebellion that would devastate both sides, and admits he might have accepted Danzo’s massacre proposal to preserve Sasuke. When offered another path, he is willing to humble himself and pursue reform 28 39.

Itachi is more comfortable protecting peace from the shadows than seeking public leadership. Nevertheless, he questions Yu’s methods and refuses to treat trust as permission for unchecked power. His reserve softens around Sasuke, Izumi, and eventually Yu, revealing affection, shyness, and a dry sense of humor 33 40 41.

Notable Quotes

“People live by relying on their knowledge and perceptions, and are bound by them. That is what we call reality. But knowledge and perceptions are vague things. Reality might be nothing more than an illusion. Everyone lives within their own fixed beliefs.” 39

“Becoming Hokage doesn't earn you everyone's recognition. Rather, someone everyone recognizes can become Hokage.” 40

“Mr. Yu, what I'm about to say may be disrespectful, but I want to make it clear beforehand. If one day I truly become Hokage as you wish, I would not want you to become another Danzo...” 40

Trivia

• Itachi once dreamed of opening a dessert shop among the Uchiha after retiring 40.
• His Mangekyō awakening comes from grief artificially imparted by the still-living Shisui, rather than Shisui’s actual death 27.
