Background / History

Childhood and the Academy

Kagami possesses an adult soul and memories of a previous life, including knowledge of the shinobi world’s original future. Orphaned, he finds a sense of belonging in the Uchiha Clan. His household consists of himself, his grandmother, and the young Shisui, whose parents also died. That attachment becomes the basis of his determination to prevent the clan’s destruction 2 5 162.

At the Academy, he cultivates an intimidating reputation rather than pretending to be harmless. He humiliates Asuma after being attacked, then defeats Kakashi with swordsmanship, elemental ninjutsu, and the Sharingan. His performance isolates him from most students and drives Kakashi to postpone graduation and intensify his training 2 3 4 5.

Elder Shinka recognizes him as a potential successor to the clan’s hawkish leadership and offers to teach him all his ninjutsu. Kagami accepts the training but rejects Shinka’s strategy of waiting for a favorable Hokage succession, insisting that the Uchiha need no village title to establish their worth 5.

Clan Ambitions and Mentorship

Itachi’s birth gives Kagami an approximate deadline for preparing against the future massacre. At the infant’s celebration, Kagami publicly challenges Fugaku, displaying his Three-Tomoe Sharingan and rejecting the assumption that his youth should delay a test of strength 9 10.

After helping contain a Nine-Tails crisis, he clashes with Tsunade over killing and inherited hostility toward the Uchiha. Jiraiya intervenes and invites him to become his disciple. Kagami accepts, although he privately doubts that mentorship can resolve the deeper clan–village conflict 15 16.

Shinobi War

Kagami treats the war as an opportunity to strengthen the Uchiha and change their standing. Fighting alongside Minato and Kakashi, he defeats Pakura, annihilates an Iwagakure jōnin with Black Flash, and overpowers the Four-Tails. The latter encounter ends with him sparing the unconscious Rōshi and retreating after Ōnoki arrives 19 20 23 28 31 32.

His growing influence draws clan members toward the radicals and away from Fugaku. When Fugaku later attempts to reassert his authority, Kagami shatters his Susanoo without activating his own Sharingan. His clash with the Third Raikage precedes the documented emergence of his Mangekyō abilities 60 61 65 69.

Madara and Sukuna

Kagami repeatedly plants ocular power in Obito as a means of reaching Madara and White Zetsu. His eventual battle with Madara becomes both a test of genjutsu mastery and part of a planned confrontation with Sukuna. When Sukuna attempts to merge with him, Kagami reveals that he has manipulated their shared restraint and pins Sukuna with a black spear 7 50 52.

At Madara’s underground hideout, he explains Mangekyō blindness through Yin–Yang imbalance and takes a dead White Zetsu for research. He also agrees not to interfere with Madara’s planned trial for Obito, even if Kakashi is killed in the process 53.

Conquest and Reconstruction of Konoha

During Konoha’s civil conflict, Kagami defeats Danzō, exposes his implanted Sharingan, and deliberately preserves him for prolonged punishment. He kills Koharu when she intervenes. Minato offers to serve as Hokage under Uchiha supremacy in exchange for mercy toward children and those who surrender 76.

Minato and Sakumo help defeat Orochimaru’s giant serpent form; Kagami finishes Orochimaru with a Susanoo slash that cleaves distant mountains. The surviving forces surrender, leaving Konoha under Uchiha control. The village is subsequently rebuilt larger and more orderly 77 88.

As clan head, Kagami separates Sasuke’s future from the punishment surrounding Fugaku and Itachi by agreeing to take him as a disciple. His household later includes Shisui, Sasuke, and Ryuzetsu, while a nearby house allows Mikoto to care for Sasuke 88 113 114.

Ōtsutsuki Conflict and the Final Battle

Kagami rejects Akatsuki’s invitation and pursues threats beyond Konoha. He seals Isshiki, openly confirms his knowledge of the original future, and asserts the Uchiha’s claim to Konoha against Hashirama and Tobirama. His preparations include secretly marking the opposing group with Flying Thunder God seals 89 102 104 105.

He organizes the Shinobi World Martial Performance to foster growth through real combat. During its later stages, he directs Shisui’s Mangekyō evolution, targets the Giant Tenseigan, destroys a celestial body, and banishes Sukuna to the Pure Land. His signal into space helps draw the attention of the wider Ōtsutsuki Clan 119 159 168 173 180.

After directly consuming a Ten-Tails, Kagami moves toward a final confrontation rather than merging with the Gate of Sealing. Within the Tsukuyomi Slaughter Mausoleum, he faces Sukuna, Madara, Hashirama, and Ōtsutsuki Yeyue, killing Yeyue during their coordinated assault. The supplied account does not establish the battle’s complete outcome; the later extra chapter shows Kagami returning to Shisui 177 187 192 193 197.

Appearance

Kagami has curly hair and a handsome face, and Madara notes a resemblance to the young Izuna. In the climactic battle account, he still looks like a teenager despite the passage of time 2 24 102 193.

• Clan-marked clothing: Habitually wears the Uchiha crest, making his affiliation immediately recognizable 16.
• Crimson ocular power: His Sharingan is perceived as unusually fierce even beside other Uchiha eyes 5.
• Right-eye seal: Can cover his right eye with a grayish-black sealing layer 95 102.
• Wide sleeves: His clothing includes broad sleeves; he also conceals a short blade in a sleeve 19 125.

Personality

Kagami’s arrogance is both sincere and calculated. He enjoys displaying Uchiha power, but also believes an openly proud and dangerous prodigy is less suspicious to Konoha’s leaders than one pretending to be harmless. He respects an enemy’s actual competence: despite regarding Hiruzen’s faction as a threat, he acknowledges Hiruzen’s strength and leadership 2 4 5.

His loyalty is strongly selective. He is warm toward ordinary clansmen and protective of Shisui, yet contemptuous toward leaders he believes would sacrifice the clan. His attachment to the Uchiha is a chosen conviction rather than something he accepts Sukuna’s description of as a weakness. That loyalty does not prevent cruelty: he threatens Mikoto, accepts possible casualties in Madara’s manipulation of Obito, and designs prolonged punishments for those who steal Sharingan 5 28 38 53 76 125.

He values peace but believes it must be secured through resistance and superior strength. Though he rejects meaningless slaughter, he seeks dangerous battles, refuses the safest path to growth, and prepares himself for death. He also admits wanting a partner and children, but suppresses those wishes until the threats he associates with the Ōtsutsuki are settled 23 81 99 119.

His everyday behavior is less austere: he teases companions, enjoys meals with his clan, and repeatedly steals Jiraiya’s money in retaliation for being blamed for his teacher’s peeping 88 110 111 113.

Abilities & Skills

Sharingan and Ocular Power

Kagami’s spiritual energy, strengthened by his adult soul and absorbed cursed energy, produces ocular power far beyond an ordinary Three-Tomoe Sharingan 2 22 31.

• Suppresses tailed beasts before formally advancing to the Mangekyō 31.
• Uses visual perception as the targeting basis for adapted slashing techniques 20.
• Deciphers the Sage of Six Paths’ stone tablet 83.
• Later traces the influence behind Sharingan evolution across the boundary between life and death 159.

Mangekyō Technique Configuration

His eyes divide offense, bodily support, control, and spatial confinement into four principal techniques 99 154.

Eye	Technique	Function
Left	Severance Release—Black Slash	Primary offensive technique; the Sharingan becomes a vessel for power his body and weapons previously could not support 69 154.
Left	Yin–Yang Conversion	Converts spiritual energy into physical energy, improving his constitution and supporting recovery 69 95 154.
Right	Crimson Demon	Control-oriented ocular technique 99 154.
Right	Tsukuyomi	Area-based spacetime confinement 99 154.

• Rather than continually adding unrelated powers, he raises these techniques’ limits and develops interactions between them 154.
• Extreme use can still make his Mangekyō bleed, as seen during the Isshiki battle 102.
• His chosen evolution is distinct from Madara’s route toward the Rinnegan 102 165.

Genjutsu and Mirror Flower Water Moon

His specialty is mental combat. He contests Madara’s immense illusion world and develops methods of casting Sharingan genjutsu without relying solely on direct eye contact 19 50.

• Mirror Flower Water Moon: Reflects ocular power through Sode no Shirayuki’s blade light; inspired by Maruboshi Kosuke 19.
• Successfully deceives Orochimaru and catches Rōshi through the blade’s reflection 19 32.
• Is not unbreakable: the Four-Tails helps Rōshi dispel it 32.
• Creates defensive and offensive constructs within genjutsu, including a chariot and Nue-like beasts 50.

Severance / Severance Release

Kagami digests Sukuna’s slashing power and reworks it through Uchiha ocular techniques 20.

• Thousand Blade Flowing Scenery Severity: A targeted, high-frequency slashing attack derived from Dismantle 20.
• Single Blade: Cicada’s Lament: Overwhelms Pakura’s perception with information while delivering the decisive attack 20.
• Black Slash: Applies ocular power to invisible slashes; a later training version requires exceptional control and is described as harder to learn than Flying Thunder God 69 140.
• Divine-art slashes: Sever Urashiki and intercept Momoshiki’s attack at a much later stage 186.

Yin–Yang Conversion and Recovery

Yin–Yang Conversion corrects the imbalance between Kagami’s overwhelming spiritual energy and his developing body 69 95.

• Nourishes his body with Yang Release chakra and gradually removes his earlier physical ceiling 69.
• Works alongside Reverse Cursed Technique; Kagami estimates his recovery is no slower than Hashirama’s 95.
• Eventually makes ordinary medicine and training ineffective on his body 110.
• Extends to advanced ocular manipulation: he customizes Shisui’s Mangekyō techniques and places Tobirama’s consciousness within one eye as a source of tactical instruction 159.

Black Flash and Natural Energy

His chakra-based Black Flash concentrates natural energy into offense rather than providing Sage Mode’s broad enhancement 28.

• Produces black-red lightning and an explosion leaving a crater over ten meters wide 28.
• Annihilates an Iwagakure jōnin with destructive power compared to a Tailed Beast Ball 28.
• Initially burns his arm and leaves half his body numb; his body cannot safely withstand the output at that stage 28.
• Helps him grasp chakra’s underlying nature and develop his understanding of Yin–Yang Release 44.

Elemental Ninjutsu

Kagami combines conventional nature transformations with his developing ocular and energy techniques 4 9 65.

• Uses Fire Release and Earth Release against Kakashi 4.
• Practices the Rasengan and unsuccessfully attempts to add Fire Release, causing an explosion 4 5 9.
• Uses Blaze Release—Crimson Lotus Prison Garment against the Third Raikage 65.
• Later incorporates Yang Release into his Flame Release, allowing it to refine natural energy 162.
• His Fire Release shape transformation impresses Ōnoki, who considers his ninjutsu mastery beyond Mū’s 133.

Tsukuyomi—Underworld Hell Great Killing Mausoleum

His integrated domain combines Uchiha ocular power with Ten Shadows, the Bringer-of-Darkness Technique, sealing, and domain-expansion methods derived from Sukuna 99.

• Draws on the Dragon Vein as an energy source 99.
• Restricts Jigen’s spacetime abilities, enabling Kagami to land attacks 99.
• Was originally prepared as a means of completely subduing an evolved Sukuna 99.
• In the later Slaughter Mausoleum confrontation, Kagami forbids substitutes, clones, and spacetime ninjutsu to force a direct battle 192.

Sealing and Flying Thunder God

Kagami begins with ocular sealing and later studies more advanced methods under Kushina and Minato 7 15 95.

• Transcription Seal: Stores portions of his ocular power in Obito over repeated encounters 7 15.
• Sukuna’s seal: Restrains both host and prisoner; Kagami can later undo his right-eye seal but deliberately retains it 52 95.
• Black Rods and spears: Restrain Danzō, Hashirama, and Tobirama 76 104.
• Isshiki’s imprisonment: Combines the Karma Seal, stone tablet, and Box of Paradise 102.
• Flying Thunder God marks: Secretly marks opponents during their confrontation and also marks Jiraiya 105 174.

Tailed-Beast and Cursed-Energy Assimilation

Kagami treats external entities as sources of energy and research rather than accepting their preferred relationship with him 2 31 177.

• Draws cursed energy from Sukuna while denying him control of the body 9.
• Collects chakra from the Nine-Tails, Four-Tails, and Eight-Tails to study their Yin–Yang properties 44.
• Uses Sukuna as a filtering core when handling Ōtsutsuki power, avoiding unwanted genetic influence 102.
• Eventually consumes a Ten-Tails directly instead of becoming its jinchūriki 177.

Susanoo

Kagami first demonstrates a Nine-Tails Susanoo within his genjutsu contest with Madara; later manifestations operate on the physical battlefield 50 77.

• Delivers the finishing blow against Orochimaru’s giant serpent form 77.
• The resulting slash cleaves mountains beyond the immediate battlefield 77.

Foreknowledge and Strategy

Kagami knows events from the original timeline and later publicly describes this knowledge as seeing the future 2 104.

• Uses the anticipated Uchiha massacre to guide long-term preparation 9.
• Understands that his own existence and Sukuna’s presence make the original sequence unreliable 2 25.
• Warns Minato about Obito’s planned extraction of the Nine-Tails during Kushina’s childbirth 105.
• Momoshiki’s own fate-reading ability cannot perceive Kagami’s future 190.

Equipment / Weapons / Items

• Sode no Shirayuki — Chakra Metal sword of “Kusanagi Sword” class; used for swordsmanship and reflected genjutsu, then passed to Shisui 3 19 127.
• Narukami blade — Eventually outgrown as a practical weapon, though Kagami still values its appearance 127.
• Orochimaru’s Kusanagi Sword — Likewise retained after becoming largely decorative to him 127.
• Minato’s Flying Thunder God kunai — Enables Minato to reach him on the battlefield; Kagami also takes one when leaving Konoha so he can be contacted in an emergency 32 89.
• Sage of Six Paths’ stone tablet — Removed from Naka Shrine and later incorporated into Isshiki’s sealing 83 102.
• Box of Paradise — Used with the tablet and Karma Seal to imprison Isshiki 102.
• Nagato’s extracted Rinnegan — Used to summon King Yama and banish Sukuna; this is not documented as Kagami awakening his own Rinnegan 173.
• Frog-shaped wallet — Stolen from Jiraiya as part of Kagami’s recurring retaliation over the bathhouse incident 110.

Relationships

• Shisui Uchiha — Younger brother and one of his deepest attachments. Kagami regulates his eye development, teaches him Yin–Yang theory, and customizes his Mangekyō abilities. Their later reunion is affectionate 5 113 119 132 159 197.
• His grandmother — Raises the orphaned household. Kagami spends years keeping her company; the helplessness associated with her death shapes his emphasis on strength and protection 5 95 113.
• Sukuna — Hostile entity sealed inside him, power source, occasional tactical collaborator, and eventual opponent. Kagami refuses his philosophy and deliberately encourages his evolution as a future challenge 2 28 99 102 193.
• Uchiha Shinka — Ninjutsu mentor and political supporter. Kagami rejects his cautious succession strategy but becomes the chosen successor of his faction 5 25.
• Minato Namikaze — Senior fellow disciple, battlefield protector, and later political ally. Minato negotiates limits on Kagami’s violence and relies on him to help protect Kushina 19 28 76 105.
• Jiraiya — Teacher and mediator who hopes to bridge the Uchiha–Konoha divide. Kagami’s irreverence includes repeatedly emptying his pockets 16 19 110.
• Kakashi Hatake — Academy rival and fellow disciple. Kagami’s insults coexist with acts of hospitality and protection, but he also accepts Kakashi’s possible death in Madara’s plans 5 17 19 53 174.
• Hatake Sakumo — Ally whose death Kagami prevents. Sakumo trusts his battlefield judgment and joins Minato when Kagami directs him to do so 77 104.
• Fugaku Uchiha — Rival authority figure. Kagami despises his indecision, undermines his leadership, and later replaces him as clan head 38 61 88.
• Mikoto Uchiha — Frequent target of his hostility over reconciliation and her family. Nevertheless, Kagami provides a nearby home so she can raise Sasuke 38 114.
• Itachi Uchiha — Resented because of the massacre Kagami knows from the original future. Kagami’s treatment leaves him fearful and restricted, while Sasuke receives a separate path 88.
• Sasuke Uchiha — Disciple and protected younger clansman. Kagami arranges his care, considers his future ocular development, and encourages a pairing with Karin 88 113 114 119.
• Ryuzetsu — Welcomed into his household as family; Kagami invites her to a meal of her choosing 113.
• Obito Uchiha — Bullied classmate, unwitting carrier of Kagami’s ocular seals, and later enemy. Kagami knows his role in the future Nine-Tails disaster 5 7 89 105.
• Madara Uchiha — Adversary and respected intellectual counterpart. Their exchanges involve genjutsu combat, ocular research, manipulation, and later preparations for the final battle 50 53 190 192.
• Danzō Shimura — Enemy who seeks control of Kagami and covets Uchiha power. Kagami ultimately imprisons him for prolonged punishment 9 36 76.
• Hiruzen Sarutobi — Initially protects him from Danzō but fears his clan-first politics. Kagami later rejects his appeals and the old leadership’s authority over Konoha 9 24 104.
• Orochimaru — Alternates between commanding officer, prospective patron, opponent, and researcher obsessed with Kagami’s body and eyes 19 36 77 104 173.
• Hashirama and Tobirama Senju — Legendary figures whose claim to Konoha he challenges. Hashirama cooperates against the Ōtsutsuki, while Tobirama’s consciousness is later confined in Shisui’s eye until Kagami releases him 102 104 159 197.
• Sage of Six Paths — Secretly assists Kagami’s ocular advancement and considers him the Child of Prophecy. Kagami rejects his authority over the shinobi world’s future 159.

Trivia

• His grandfather is a different Kagami Uchiha. Kagami explicitly discusses the deceased namesake as “Ancestor Kagami” 5.
• His Academy routine includes mental Rasengan practice during daytime dozing, evening Nintaijutsu training, nighttime theory study, and seven hours of deep sleep 5.
• Shinka’s faction exaggerates his battlefield accomplishments when spreading his reputation; its claims that he killed the Four-Tails or nearly killed Ōnoki exceed the documented encounter 32 38.
• Although the Rōshi battle presents him as the Nine-Tails’ jinchūriki, the detailed account shows him wearing tailed-beast chakra, and later chapters discuss his stored Nine-Tails chakra separately. Kushina remains associated with the Nine-Tails during subsequent events 32 44 65 76.
• His clan’s regard eventually shifts from respect for a leader toward faith in a god, while daily administration passes increasingly to Shinkwa and Genko 177.
