Mangekyō Sharingan card acquired 7 Draws a Mangekyō Sharingan but keeps it in reserve rather than immediately equipping it.
Custom Uchiha disguise and [Coincidence] 7 9 10 Creates a body that grows from infancy. By age four, it has awakened the Sharingan; [Coincidence] allows him to redirect events.
Academy graduate → ANBU → Hokage’s personal guard 12 His disguises graduate as the strongest of their year, then advance through accumulated missions and achievements.
Three-tomoe Sharingan and [Wood Release: Level One] 14 Displays three tomoe and purchases weakened Wood Release, chiefly to obtain durable Wood Clones.

The Rinnegan-like pattern briefly shown during the clan assault is not a confirmed Rinnegan awakening. He later possesses a separate pair of Rinnegan in his inventory, awaiting implantation 16 34.

Background / History

Watanabe Ichiro is killed by a dump truck and awakens as a transparent spirit on a battlefield between the Senju and Uchiha clans. Recognizing the Naruto setting, he discovers that Hashirama and Madara are still young and that the familiar story has not yet begun 1.

The [Fun-Seeker] system rewards him for causing trouble. He chooses Black Zetsu as his bound target, obtaining location tracking and doubled rewards for changes involving him. His initial objective is to drag the secretive schemer into public view and make his name famous throughout the Shinobi World 1.

Rather than adopting one permanent body, Ichiro uses character cards and custom disguises. His first major performance consists of two nearly identical Watanabe brothers, both named Ichiro. Their supposed history as the last survivors of a northern clan is part of the constructed persona, not his original background 2.

Appearance

  • Original spirit: Transparent and incorporeal; shuriken and kunai pass through him 1.
  • Older Watanabe brother: White-haired boy missing his right leg, initially using a wooden stick and later Hashirama’s crutch 2.
  • Younger Watanabe brother: Almost identical white-haired boy; during his staged final moments, black markings spread across his body and his Sharingan disappears 2 6.
  • Uchiha Ichiro: White-haired, with the Uchiha Clan’s good looks. His hair fuels rumors of Senju involvement, while his gentle public demeanor makes him a highly sought-after bachelor 11 14.
  • Mangekyō and Susanoo: Red eyes with black circular patterns; manifests a red Susanoo with an armored giant form 34.
  • Black Zetsu impersonation: A sticky, slime-like exterior that can coalesce from a puddle into a humanoid shape 31.

Personality

Ichiro initially treats the world as a game and its inhabitants as sources of points. He maintains little contact with people who cannot reward him, enjoys manipulating major figures, and refuses to cast himself as a champion of justice. Even his support for unification is framed as something he personally finds appealing rather than a moral obligation 19 38.

His public personas conceal this detachment. The older Watanabe brother is gentle and supportive, while the younger brother is lively, stubborn, and affection-seeking. Uchiha Ichiro appears modest, forgiving, and reserved; in reality, he secretly punishes ANBU seniors who mistreat him while allowing Tobirama to believe he bears no grudge 6 14 17.

He prefers efficient schemes to unnecessary effort, frequently leaving disguises on autopilot or zoning out around reliable allies. Nevertheless, he enjoys spectacle: he uses Complete Body Susanoo partly because looking impressive matters to him, despite its irreversible ocular-power cost 7 36 37.

Hashirama’s death marks a change. Hearing villagers mourn him—especially a child expecting him to return with candy—forces Ichiro to recognize that these are real people rather than background characters. Tobirama notices a new warmth beneath his usual detached behavior 38.

Abilities & Skills

[Fun-Seeker] System

  • Awards points for disturbances and emotional reactions; Black Zetsu-related changes provide doubled rewards after target binding 1.
  • Provides a lottery, shop, inventory, skill library, and target-location display 1 7 15.
  • Can train a disguise’s basic combat abilities while it is idle 26.
  • Performs purchased technical assistance, including Flying Thunder God calculations and analysis of Black Zetsu’s composition 17 47 50.
  • Disguise deaths generate far greater emotional rewards than ordinary mischief, encouraging Ichiro to plan dramatic retirements 26.

Spirit Form and Character Disguises

  • Can leave a body and travel in spirit form, gathering information while the system manages his disguise 7 18.
  • Drawn character cards can appear directly as adults; custom-created disguises must grow from infancy 7.
  • Free automatic management supplies only survival and simple conversation. Independent behavior consistent with a detailed personality requires daily points 7.
  • Reclaiming the shattered Watanabe card removes its buried body, preventing Black Zetsu from finding it 7.
  • The separate [Disguise] skill makes an impersonation impossible to see through after sufficient time spent with the subject. Ichiro fulfills this condition by allowing Black Zetsu to follow him 24 31.

[True Damage Infusion]

  • Can be applied to any weapon; an infused kunai cuts through Madara’s Susanoo 5 26.
  • Breaks Wood Release defenses, giving Ichiro an advantage in close combat against Hashirama 31.
  • Can also be applied to his hand, allowing him to pinch a sample from Black Zetsu 47.

Sharingan and Mangekyō Sharingan

  • Uses Sharingan perception and genjutsu; three-tomoe genjutsu is sufficient to incapacitate a protesting clan elder 14 39.
  • His Mangekyō skill, [Amenominaka], enhances combat attributes, expands ninjutsu range, predicts taijutsu attacks, and counters blind-spot attacks 31.
  • [Amenominaka] reduces ocular-technique consumption to one-tenth and also lowers ninjutsu consumption 31.
  • Uses Mangekyō power to control the rampaging tailed beasts and manifests Complete Body Susanoo 33 36.
  • The system-produced Mangekyō cannot replenish ocular power. Repeated use causes blurred vision; its eyes can be gifted to another person 26 46 49.
  • The instantaneous healing he presents as an ocular ability is actually [Coincidence], not [Amenominaka] 33 37.

Wood Release

  • Level One: A heavily weakened version, purchased primarily for Wood Clones that withstand some damage before dispersing 14.
  • Complete Version: Grants full mastery, with strength determined by chakra output; includes Wood Golem Technique and Cutting Sprigs 24.
  • Uses transformed clones as false Black Zetsu sightings, wounded victims, scouts, and covert observers 14 31 42.
  • Clone memories return upon dispersal. Burning the remaining wood helps erase evidence 14.
  • Supports his injured body and helps reattach severed limbs alongside Medical Scrolls, but initially cannot stop [Netherworld] from removing them 44 45.

Flying Thunder God and Reverse Flying Thunder God

  • Teleports using marked objects and coordinates; system assistance handles the calculations while Ichiro supplies chakra 17.
  • Uses a mark placed on Kagami’s clothing to bypass the destruction of his marked kunai and attack at close range 26.
  • Portable Reverse Flying Thunder God patches allow their wearers to sense and answer summons 33 46.
  • Kagami’s [Netherworld] can seal off space and prevent his escape through Flying Thunder God 45.

[Coincidence]

  • Searches possible futures for one matching his wish and steers events toward it without detectable inconsistencies 9.
  • Brings Hashirama to him before Tobirama can abduct him for experiments; later helps orchestrate the clan assault and saves Tobirama from fatal injuries 9 16 33.
  • Initially described as consuming lifespan, with a deduction upon activation whether or not he makes a wish. The cost doubles with successive uses 9.
  • Later passages describe the expenditure as fate points. Ichiro warns that repeated use could exhaust his current disguise 31 33.

Forbidden Techniques and Supporting Skills

  • [Detection] and [Transcription]: Secretly copy scroll contents into the system before he gains open access as Tobirama’s disciple 17.
  • [Act at Will]: Raises technique proficiency to 100 and permits activation without prerequisites such as hand seals or incantations 24.
  • Impure World Reincarnation preparations: Collects tissue from corpses as potential summoning material; proposes using the technique to reunite Kagami with his wife and resolve a misunderstanding 23 36 44.
  • Clones and basic ninjutsu: Uses Shadow Clones, Transformation, Substitution, Great Fireball Technique, and Uchiha Shurikenjutsu 4 14 26 30.

[Netherworld]

  • Installed in his replacement Uchiha Kagami disguise through the pair of Mangekyō eyes bearing the ability 49.
  • Temporarily manifests a separate space in which its wielder controls admission and expulsion, including the removal of individual body parts 43.
  • Its original wielder uses it to counter Ichiro’s Flying Thunder God and sever his limbs 44 45.

[Absolute Command]

  • Reveals personnel data when Ichiro establishes an organization 40.
  • Can compel absolute obedience after specified conditions are met; those conditions are not detailed in the provided passages 40.
  • Acquired while he is considering founding an organization, but does not improve his individual strength 40.

Cooking and Deception

  • Wins Hashirama and Madara’s friendship through grilled fish and hot pot; his cooking, rather than combat strength, initially earns their respect 2.
  • Uses false grief, apparent vulnerability, carefully staged injuries, and affectionate language to manipulate both allies and Black Zetsu 6 23 31 47.
  • Maintains convincing cover even when Tobirama begins questioning his knowledge of Black Zetsu 37.

Equipment / Weapons / Items

  • Character Profile Cards: The purple Watanabe twins card, white-grade disposable disguises, and later cards used to prepare additional identities 1 7 14 40 49.
  • Kunai, blades, and Explosive Tags: Used in his ambush of the Senju and Uchiha leaders; some weapons carry True Damage Infusion or Flying Thunder God marks 4 5 26.
  • Hashirama’s Wood Release crutch: Given to the older-brother persona; its scorched remains are buried with the retired Watanabe disguise 2 7.
  • Reverse Flying Thunder God patch: Worn at his waist to receive summons 33 46.
  • Uchiha Gunbai: Carried on his back and handed to Madara as a walking stick during their later encounter 25.
  • Rinnegan: A separately drawn pair kept in reserve, not yet implanted in the documented passages 34 36.
  • Uchiha Stone Tablet: Stolen after Black Zetsu alters it and stored in his inventory 19 34.
  • Military Rations Pills: Available in assorted flavors, with beneficial effects and none of ordinary pills’ side effects 1 34.
  • Food and ingredients: Stored alongside cooking supplies; system storage keeps his old ingredients fresh 26 34.
  • Medical Scrolls and corpse tissue: Used for injury treatment and preparations involving Impure World Reincarnation 34 45.

Relationships

  • Black Zetsu — Bound system target, principal victim of his schemes, and unwitting collaborator. Ichiro tracks him, impersonates him, steals his altered tablet, and pretends to accept Infinite Tsukuyomi while extracting a sample for analysis 1 19 31 47.
  • Hashirama Senju — Childhood friend of the Watanabe personas, later protector and teacher of Uchiha Ichiro. Ichiro gravely wounds him in the first ambush and later fights him under Black Zetsu’s appearance; Hashirama’s death eventually breaks through his emotional detachment 2 4 12 31 38.
  • Madara Uchiha — Childhood friend, later Hokage and clan leader. Ichiro admires his unification ideals, succeeds him as patriarch, and ultimately kills him, alarming Black Zetsu with his staged obsessive devotion 2 19 23 26.
  • Tobirama Senju — Former assassination target who becomes his teacher and closest trusted support. Tobirama praises his system-assisted learning, grants access to forbidden techniques, and grows suspicious of his connection to Black Zetsu; Ichiro later saves his life 4 17 33 37.
  • Uchiha Izuna — Initially wounded in Ichiro’s ambush; later targeted through underhanded schemes. Tobirama suspects Ichiro of sabotaging attempts to revive him 5 11 14 19.
  • Uchiha Kagami, former third-in-command — Rival for the patriarch position. After losing to Ichiro, he awakens a Mangekyō ability that counters Flying Thunder God, works with Black Zetsu, and arranges Ichiro’s capture. Ichiro kills him and prepares a replacement disguise bearing his identity 23 26 29 42 47 49.
  • Kagami Uchiha, the kidnapping participant — Warns Ichiro indirectly while cooperating with the elders’ plot. The elders hold his younger brother; Ichiro suspects coercion and leaves a clone ready to help him 41 42.
  • Uchiha elders — Opponents of his leadership who exploit clan resources to drug and abduct him after being intimidated by his rival 39 41 42.

Story Role / Major Arcs

Watanabe Brothers and the Battlefield Ambush

Ichiro befriends young Hashirama and Madara through shared meals, then introduces the suspicious younger-brother persona. Once both boys are attached, he stages the older brother’s death in a clash between their clans and leaves gifts behind to deepen their guilt 2 3.

Years later, the surviving-brother persona ambushes Tobirama, Hashirama, Madara, and Izuna. His infused weapons penetrate defenses that ordinary tools cannot, but Madara’s Susanoo leaves him pinned and mortally injured. Ichiro deliberately ends the disguise while publicly praising Black Zetsu as an invincible savior 4 5 6.

Hashirama and Madara bury him by their meeting river. Their clans subsequently form an alliance, and Madara becomes the First Hokage. Ichiro reclaims the card and begins another life elsewhere 7.

Uchiha Outsider and Tobirama’s Disciple

As four-year-old Uchiha Ichiro, he chooses the Uchiha Clan because it offers more opportunities to influence the story. White hair and his father’s reputation make him an outsider; he deliberately encourages aspects of this image to reduce social obligations and create a pitiable persona 9 11 21.

He advances into ANBU and becomes a Hokage guard. An engineered assault exposes his disguise’s mixed parentage and attracts Black Zetsu’s attention as a possible route to the Rinnegan. Meanwhile, Tobirama offers Flying Thunder God and eventually accepts him as his personal disciple 12 16 17.

Patriarch Succession and Black Zetsu’s Frustration

Ichiro steals the altered Uchiha Stone Tablet, interfering with Black Zetsu’s plans for Madara. He becomes the clan’s first white-haired patriarch and maintains order through force rather than affection or clan loyalty 19 23 26.

He defeats Uchiha Kagami’s challenge using Flying Thunder God. Kagami’s knowledge of his private techniques leads Ichiro to infer that Black Zetsu has leaked information; the defeat later drives Kagami’s Mangekyō awakening 26 29.

Five Kage Summit

Ichiro attends through a Shadow Clone while his body guards the tailed-beast scrolls. He knocks out the guards, leaves a wounded Wood Clone as a false victim, and impersonates Black Zetsu before the assembled leaders 30 31.

The impersonation escalates into a fight with Hashirama, forcing Ichiro to equip his Mangekyō. During the subsequent crisis, he controls the tailed beasts and uses [Coincidence] to save Tobirama, disguising the rescue as an unexplained ocular ability 31 33.

After Hashirama’s death, Ichiro declares his intention to inherit Madara’s unification ideals. His Complete Body Susanoo crushes resistance, and he leaves Tobirama to handle the political aftermath 34 36.

Capture, Kagami’s Defeat, and a New Direction

Back in Konoha, Ichiro knowingly drinks a controlled amount of poisoned sake and cooperates with the elders’ kidnapping plan. His rival’s [Netherworld] initially blocks teleportation and removes his limbs, but he repairs his body and ultimately kills Kagami 42 44 45 47.

He then manipulates Black Zetsu into explaining Infinite Tsukuyomi and permitting a small physical sample. Afterward, he prepares a replacement Kagami disguise for activities outside Konoha, while Uchiha Ichiro recovers with impaired vision from Mangekyō overuse 47 49.

By the latest documented events, Ichiro is helping with Hokage duties and managing Konoha’s affairs, showing signs of gradually taking power 50.
