Biodata

Power Progression

Background / History

Family and the Original Lei

Lei’s mother, Uchiha Yumi, was a chūnin rescued from Amegakure attackers by Chiaki, a Senju chūnin. They completed her escort mission together and became lovers. Chiaki later sacrificed himself with an explosive tag to kill an Amegakure jōnin and save Yumi 1.

Yumi learned she was pregnant while recovering in Konoha Hospital. Her friend Uchiha Miko persuaded her to live and raise the child. Lei’s difficult birth left Yumi chronically ill, but she continued taking missions to support him until her death 1.

The original Lei’s Rinnegan awakening devastated his body rather than earning him recognition. Clan members believed he had failed to awaken the Sharingan and called him useless. Although Grand Elder Uchiha Yama prohibited open slander, bullying continued privately and at the Academy. Physical suffering and ridicule eventually killed him 1.

Yu Lei’s Transmigration

Yu Lei was electrocuted while writing his novel late at night. His soul entered the recently deceased Lei’s body, and he awakened in an unfamiliar classroom with the original owner’s memories 1.

His knowledge of the Naruto storyline informs both his ambitions and his attempts to avert future tragedies. He recognizes Kushina’s future role, knows Kurama’s name, discusses Madara’s survival with Mito, and warns Hizashi about a future Kumogakure peace delegation 11 15 16 37.

He later uses this knowledge to question the assumption that a Rinnegan bearer will necessarily save the world, encourages Minato and Nami to have a child, and prepares for the Night of the Nine-Tails rather than waiting for events to unfold unchanged 72 89 164.

Adulthood and Family

Lei and Kushina reach their coming-of-age ceremonies on the same day. By this period, he serves as an Academy instructor and has helped introduce Minato to Nami Uzumaki, an orphan he rescued in the Land of Grass 88 89.

After Kushina becomes pregnant, Lei marries her in a public ceremony officiated by Hiruzen. Mikoto is also later confirmed pregnant, and she reminds Lei that their own wedding is scheduled for the following week 145 149 160.

By the ending, his household has expanded considerably. Kaguya gives birth to their son Uchiha Shouye in the second year of the concluding peace, while Mikoto and numerous other partners also have children. The epilogue describes the flourishing of their bloodlines and the Uchiha Clan throughout the Shinobi World 169 170.

Appearance

• Childhood condition: Became emaciated after his first Rinnegan awakening; recovered from his frailty after the system’s activation 1 2 6.
• At age ten: Stands 1.7 meters tall, noticeably taller than his classmates and even many sixth-year students 34.
• Features: Medium-long hair, swordlike eyebrows, striking eyes, a high nose bridge, thin pale-red lips, and a muscular build. His ordinary eyes are black; activating the Sharingan turns them scarlet 29 34.
• Usual outfit: A gray, open-front shinobi top modeled on future Sasuke’s clothing, a blue sash, blue-black trousers, weapon pouches, and black ninja sandals 34.
• After graduation: Wears his genin forehead protector over his forehead specifically for protection 46.
• At age eleven: Karura remarks that his height makes him look fourteen or fifteen 66.
• Later hair description: A later encounter with Mei Terumi describes him as having distinctive white hair; the supplied passage does not explain the change from his earlier appearance 150.
• Mangekyō patterns: His first completed Mangekyō has six-pointed-star patterns. After the Itachi- and Sasuke-version eyes merge, its pattern matches Sasuke’s Eternal Mangekyō Sharingan 53 164.

Personality

Lei is affectionate and protective toward those close to him. He rushes to rescue Kushina from bullies, repeatedly comforts her when she cries, and accepts responsibility for protecting her as the future Nine-Tails jinchūriki 4 5 14 24.

He is also calculating about his advantages. He negotiates with Yama for techniques and protection, prefers self-study over a teacher he suspects would monitor him, and times his activities around system rewards. During his confrontation with Hiashi, he postpones the match long enough to collect additional plundering gains 6 29.

His confidence frequently becomes possessiveness and provocation. He publicly claims responsibility for protecting Mie, mocks Hiashi, and pressures Tsunade over her supposed interest in Dan Katō. By contrast, after defeating Fugaku, he deliberately credits the victory to Fugaku’s carelessness to preserve the young clan leader’s dignity 12 28 38.

In battle, Lei distinguishes sharply between school matches and enemy encounters. He accepts Fugaku’s and Hiashi’s defeats without killing them, but eliminates the Amegakure squad without hesitation—even cutting down a chūnin who begins to surrender. Tsunade and Mikoto are startled by his ruthlessness 12 29 49 50.

His later conduct also includes coercion toward prospective partners. He demands that Suiren repay her rescue by bearing his child, threatens Yanryū until she agrees to accompany him, and justifies Pakura’s capture as a means of preserving her Scorch Release bloodline for Konoha despite her objections 93 124.

Despite his growing power and expanding household, he remains capable of recognizing personal neglect. When Mikoto points out that Kushina has been waiting for him while he visits other partners, he feels guilty, admits his carelessness, and immediately goes to her 142.

His political confidence ultimately becomes overt authority: he orders villagers to accept Tsunade as Fourth Hokage and declares himself her Hokage Advisor. The ending presents peace as the result of his defeat of powerful enemies and destruction of the conspiracies threatening the world 160 170.

Abilities & Skills

Naruto Plunder System

The system allows Lei to acquire attributes, possessions, and other rewards from important characters 2.

• Proximity and contact: Nearby presence, hand-holding, and closer contact produce different plundering rates. His first ordinary contact with Kushina increases the listed amount from 0.1% to 1% and shortens its countdown 2 9 17.
• Progress rewards: Partial completion can grant chakra or ocular power before the targeted physique or eye ability is fully acquired 4 9 29.
• Targets: Documented targets include sage bodies, Sharingan, Byakugan, money, clothing, and ninja tools 22 25 29 34 50.
• Forced plundering: While Tsunade treats him, his body traps her hand and drains chakra as the system completes his basic Senju sage body. She is left exhausted and asleep 22.
• Battlefield limitation: Equipment destroyed during combat may be unavailable as loot; the system attributes the jōnin’s meager rewards to explosive-tag damage 50.
• Kill rewards: Defeated enemies can yield bloodline abilities and entire mastered technique sets. Killing the Third Kazekage grants Magnet Release and his ninjutsu, while killing Hanzō grants his poison, movement, combat, and Water Release techniques 64 75.
• Lifespan rewards: Killing the Third Kazekage adds 36 days to Lei’s lifespan. His later panel records 93 years and 36 days, although the supplied passages do not account individually for every increase 64 88.
• Independent eye rewards: The system states that rewarded bloodline eyes are independent and do not affect his other eyes. Lei interprets this as allowing him to obtain additional eye sets if necessary; this statement is not itself an explicit guarantee that his first Mangekyō cannot deteriorate 53.
• Dual cultivation and fusion: Later notifications identify dual cultivation as a plundering method. Indra’s Chakra automatically fuses with his Asura Sage Body, while his acquired Itachi-version Mangekyō automatically merges with the Sasuke-version eyes 90 160 164.

Sage Bodies and Chakra

• Possesses a basic Senju sage body and an intermediate Uzumaki sage body by age ten 34.
• His complete basic Senju physique lets him absorb 20 ka of newly supplied chakra in ten minutes 24.
• Has yin, yang, fire, lightning, earth, wind, and water chakra affinities 2 34.
• Despite his reserves, early Rinnegan use causes marked pallor and exhaustion 15 17.
• His later panel records intermediate Senju and Uzumaki sage bodies and 254.5 chakra units 88.
• Eventually possesses an Asura Sage Body, which combines with newly acquired Indra’s Chakra to produce the power of all creation and a further Rinnegan awakening 160.
• Reaches 60% progress toward Kushina’s Mount Myōboku senjutsu; the cited notification records partial progress rather than completed mastery 90.

Rinnegan

Lei’s strongest early trump card is the Rinnegan, which he initially keeps concealed from village observers 15.

• Shinra Tensei: Repels Kurama’s Tailed Beast Bomb into his face and drives Kurama backward with the same expanding force 15.
• Deterrence: Kurama surrenders after recognizing the Rinnegan and becomes willing to listen to Lei 16.
• Cost: The demonstrated attack consumes a large amount of chakra and leaves Lei needing rest 15 17.
• Later awakening: Fusion of Indra’s Chakra with his Asura Sage Body reshapes his ocular power and grants two additional techniques. This occurs despite the Rinnegan already appearing in his earlier panels 25 34 160.
• Time Reversal: Turns time back by several seconds at an extreme chakra cost 160.
• Amenotejikara: Exchanges positions and enables instantaneous movement within a specified range. Lei later uses it to seize Kaguya 160 169.

Sharingan and Genjutsu

• Three-tomoe Sharingan: Acquired by the early-graduation period and used during the Amegakure ambush 34 49.
• Demonic Illusion: Shackling Stakes Technique: Immobilizes opponents through eye contact. Lei uses it against Hiashi’s activated Byakugan and repeatedly combines it with lethal follow-up attacks against Amegakure chūnin 29 49.
• Other recorded genjutsu: Mirror Heaven and Earth Exchange and Genjutsu: Sharingan 25 34.
• Mangekyō Sharingan: Completes the Sasuke-version six-pointed-star Mangekyō after previously reaching 50% progress. Its acquisition grants mastery of Perfect Susanoo, Amaterasu, and Kagutsuchi 46 53.
• Susanoo: Manifests a gigantic purple chakra avatar. Against the Four-Tails jinchūriki, its skeleton forms first, followed by muscles and chakra pathways 104.
• Predictive perception: Reads Jūzō Biwa’s sword movements and controls their duel by striking openings in his defenses 110.
• Bringer-of-Darkness Technique: Listed as mastered in his later panel. Lei uses it to deprive the Third Raikage of sight before binding and killing him 88 136.
• Kotoamatsukami: Demonstrates the consciousness-altering Mangekyō genjutsu against Obito, leaving him blank-eyed and motionless 147.
• Eternal Mangekyō Sharingan: Results from the automatic fusion of his Sasuke- and Itachi-version Mangekyō. He retains both versions’ abilities, although the supplied passage does not individually enumerate the newly added Itachi-version techniques 164.

Byakugan

• Begins plundering Mie’s main-family Byakugan at the Academy and has acquired it by his age-ten status panel 25 34.
• Uses it during his post-battle search of the Amegakure squad, then deactivates it to avoid wasting chakra 50.

Ninjutsu

Learning Talent and Chakra Control

• Mind’s Eye of the Kagura: Senses presences within several hundred meters and detects the chakra changes accompanying Obito’s Kamui, allowing him to evade its spatial vortex 146.

Swordsmanship and Taijutsu

• Kusanagi swordsmanship: Cuts incoming shuriken apart and forces Minato to concede after two sword strikes 35.
• Lethal speed: Slashes the throats of four Amegakure genin in rapid succession and later kills both jōnin 49 50.
• Uchiha Dance Taijutsu: Listed as proficient in his status panel 34.
• Mobile close combat: Combines Body Flicker with kicks and repositioning to overwhelm opponents such as Fugaku 12.
• Uchiha Dance in extended combat: Evades Kisame’s heavy punches with agile footwork while chaining palm chops, elbows, knees, and kicks into attacks on vital points 100 101.
• Chain-and-Sickle Two-Stage Strike: Acquires Hanzō’s mastered technique and adapts its linked attacks to the Kusanagi Sword. Against Jūzō, chakra threads help redirect the blade around Kubikiribōchō’s guard 75 101 110.
• Instant Blade Slash: Cuts Kisame’s greatsword in two and ends the contest with Kisame acknowledging complete defeat 101.
• Teleportation-assisted sword combat: Combines Flying Thunder God movement with rapid blade attacks and Chidori Blade during later battles 111 120.
• Kage-killing combination: Blinds the Third Raikage with genjutsu, binds him with Wood Release, and kills him with the Kusanagi Sword and Chidori Blade 136.

Poison Resistance and Tailed Beast Power

• Poisonous Body Technique: Acquired at mastery from Hanzō. Lei identifies its benefit as immunity to all poisons 75.
• Four-Tails power: Masters Son Gokū’s power through the system without the supplied passage establishing a conventional sealing procedure 108.
• Partial transformation: Develops scales, an altered mouth, beastlike markings, and thick tails while fighting Han 108.
• Tailed beast combat: Overpowers Han in their transformed clash and leaves him gravely wounded, requiring Ōnoki’s intervention 109.

Relationships

• Uchiha Mikoto — Childhood friend and first love. She cared for him after his mother’s death, supports him in duels, and knows about his Rinnegan. Lei later reassures her that she is his principal wife 1 12 13 15 45. Her attributes provide several major advancements, including his Mangekyō versions and Indra’s Chakra. She is later pregnant, their wedding is scheduled, and she gives birth during the concluding period 53 149 160 164 169.

Story Role / Major Arcs

Academy Recognition

Lei’s rescue of Kushina and victory over Fugaku overturn his reputation as a sickly failure. His classmates begin treating him with respect instead of disgust 4 12 13.

His growing relationships also attract political attention. Danzō attempts to recruit him into Root, while Mito uses his mixed heritage to overcome Hyuga objections to his engagement with Mie 30 31.

Graduation and Tsunade’s Team

At ten, Lei enters the graduation assessment and swiftly defeats Minato. He becomes a genin and works with Kushina and Mikoto under Tsunade, initially completing village missions 34 35 44 45 47.

Before acquaintances leave for the front, he warns Mie, Minato, and Nawaki about Amegakure explosive tags. Nawaki’s public use of “brother-in-law” exposes Lei’s relationship with Tsunade, drawing Jiraiya’s distress and Hiruzen’s disapproval 43.

Antidote Work and Border Ambush

Lei, Kushina, and Mikoto gather herbs for Tsunade’s research into Ibuse’s poison gas. Their delivery enables a successful step in her antidote testing 46 47.

On a subsequent outing with Tsunade and Mikoto, Lei learns three Wood Release techniques before confronting nine Amegakure ninja. He kills the four genin and three chūnin with Flame Formation, genjutsu, fire techniques, and swordsmanship, then defeats the two jōnin. His complete elimination of the squad shocks his observers 48 49 50.

Frontline Rise and Danzō’s Schemes

At the military camp, Lei proves his learning talent to Jiraiya by immediately reproducing the Shadow Clone Technique. Meanwhile, Danzō instructs Ryoma to contact Hanzō and arrange Lei’s death 52.

Lei completes his Sasuke-version Mangekyō and confronts Hanzō, who is driven off. Afterward, Lei detects Ryoma’s insects and threatens him, while Danzō sends a warning to Hiruzen portraying Lei as dangerously powerful 53 55 57.

His conflict with Danzō becomes physical when he severs Danzō’s right arm. Sensing Tsunade and Sakumo approaching, Lei abandons the immediate attempt to kill him and instead attacks the severed arm with a fireball 59.

Sunagakure Withdrawal and the Third Kazekage

Recognized by Sakumo as a superior fighter, Lei challenges Sunagakure’s leading combatants and arranges a duel with the Third Kazekage. Before the confrontation, he obtains the Wood Human and Flying Thunder God techniques and practices teleportation with marked kunai 62 63.

Lei kills the Third Kazekage and plunders his Magnet Release and ninjutsu. Sunagakure withdraws, and Karura becomes Lei’s fiancée, with Lei promising that both he and Konoha will protect her 64 66 68.

Ōnoki, Hanzō, and the Amegakure Orphans

During a confrontation with Ōnoki, Lei plants a Flying Thunder God formula directly on him, escapes Dust Release, and prepares a large Rasenshuriken 71.

After teaching Rasengan and Rasenshuriken to Jiraiya, Lei learns that Tsunade and Orochimaru have been defeated by Hanzō and that Tsunade is injured. He immediately sets out for the Amegakure battlefield 72.

Lei subsequently kills Hanzō and gains his mastered techniques, including Poisonous Body Technique and Chain-and-Sickle Two-Stage Strike. He then turns his attention back toward Danzō 75.

In Amegakure, Lei persuades Konan to leave Nagato and Yahiko and accompany him to Konoha. He promises to feed and train her, later bringing both her and Yumiko into Tsunade’s residence 77 85 87.

Academy Instruction and Expanding Household

Following the later passage of time, Lei serves as an Academy instructor and reaches adulthood alongside Kushina. He and Kushina help establish Minato’s relationship with Nami Uzumaki 88 89.

His household expands through both affectionate relationships and coercive encounters. He takes in Suiren after demanding repayment for saving her and threatening Yanryū, while Miru also becomes one of his acknowledged partners 93 113.

Kisame, Han, and the Seven Ninja Swordsmen

Lei fights Kisame with Water Release, Wood Dragon, Mayfly, Uchiha Dance Taijutsu, and swordsmanship. He breaks Kisame’s greatsword with Instant Blade Slash, demonstrates the Wood Dragon’s destructive power against his created forest, and leaves Kisame alive to acknowledge defeat 100 101.

He later confronts the Four-Tails jinchūriki, manifesting Susanoo, and uses Magnet Release to repel an Iwagakure ambush at Green Dam. Against Han, he reveals Lava Release and a Four-Tails partial transformation, eventually leaving the Five-Tails jinchūriki unable to continue fighting 104 106 107 108 109.

Ōnoki rescues Han with Light-Weight Rock while attacking Lei with Dust Release. Before Lei can pursue, the Seven Ninja Swordsmen surround him and his companions 109.

Lei overwhelms Jūzō Biwa in their opening sword duel, then faces the remaining six. Wood Locking Wall withstands their combined attacks, after which he traps them with Swamp of the Underworld, pierces them with wooden spikes, and follows up with Flying Thunder God-assisted attacks 110 111.

Kannabi Bridge Assignment and Pakura’s Capture

Hiruzen assigns Lei to lead Kakashi on a mission to destroy Kannabi Bridge and permits him to select two Academy students for field training. Lei chooses Obito and, after Asuma is withdrawn by his mother, Kurenai 117.

During the ensuing operations, Lei uses teleportation and swordsmanship against Mahiru and kills Iwagakure soldiers with Cutting Sprigs while confronting Kitsuchi 120 121.

He later fights Pakura, combining Water Release and Flying Thunder God kunai before trapping her in Wood Release vines. Rather than kill her, he carries her toward Konoha’s camp and declares that her Scorch Release bloodline should be preserved for Konoha, provoking both Pakura’s anger and Kurenai’s jealousy 124.

Victory over the Third Raikage

Lei attacks Ōnoki and the Third Raikage with Rasenshuriken as A and Killer B withdraw. He then blinds the Third Raikage with Bringer-of-Darkness, restrains him with Wood Release, and kills him with the Kusanagi Sword and Chidori Blade 136.

The Third Raikage’s death forces the invading forces to retreat and secures Konoha’s victory. Lei seals the body in a scroll and receives new Lightning Release mastery from the system 136.

By his subsequent return home, Danzō has also been killed by Lei on the battlefield 142.

Marriage and Countering Obito

After being reminded that he has neglected Kushina, Lei returns to her. Her pregnancy leads to a grand wedding, with Hiruzen publicly witnessing their vows and Lei promising to protect her and their unborn child 142 145.

Lei subsequently confronts Obito’s newly awakened ocular power. Mind’s Eye of the Kagura allows him to anticipate Kamui’s activation, and he combines Rasengan with Flying Thunder God kunai before using Kotoamatsukami to subdue Obito 146 147.

When he later encounters Minato and the pregnant Nami, Lei warns that an infiltrator has targeted the Uzumaki Clan and urges Minato to assign two Anbu as protection. He also cautions Mikoto about her own pregnancy 149.

Fourth Hokage Tsunade and Final Ocular Advancements

Lei publicly orders acceptance of Tsunade as Fourth Hokage, declares himself Hokage Advisor, and uses Wood Clones to help clean the streets 160.

He then acquires Indra’s Chakra from Mikoto. Its fusion with his Asura Sage Body produces a further Rinnegan awakening and grants Time Reversal and Amenotejikara 160.

Rather than ignore Black Zetsu and Obito’s retreat, Lei follows their movements, secretly marks their cave with Flying Thunder God, and overhears their plans concerning the Uzumaki Clan 162.

In preparation for the coming Night of the Nine-Tails, he acquires the Itachi-version Mangekyō from Mikoto. The system merges it with his existing Sasuke-version eyes to create the Eternal Mangekyō Sharingan 164.

Kaguya and the Era of Peace

The ending credits Lei with subduing Madara and dismantling the forces behind the world’s conflicts 170.

Kaguya attempts to escape through Yomotsu Hirasaka, but Lei catches her with Amenotejikara. He urges her to abandon war and live with him, pressuring her with the possibility that her sons could seal her again. She ultimately agrees to return to Konoha 169.

The Shinobi World enters an era of peace under Lei’s rule. His partners give birth in succession, Kaguya bears Uchiha Shouye, and the final chapter depicts a harmonious household and a flourishing Uchiha Clan without the former cycle of conspiracies and warfare 169 170.
