Background / History

Originally named Ye Yuan, Gen recalls helping a lost child find their parents before inexplicably transmigrating. He awakens as an Uchiha resurrected by Orochimaru through the Impure World Reincarnation technique, with no clear explanation for why his summoned body belongs to the Uchiha clan. 2

Orochimaru quickly notices that Gen behaves abnormally for a reanimated body and attempts to keep him under control. Gen, meanwhile, immediately begins considering how to escape Orochimaru’s command while extracting useful resources from him. 1 2

Gen later uses the identity Uzumaki Reikawa to enter Konoha, presenting himself as a displaced Uzumaki survivor. The persona gives him access to Konoha while concealing both his Edo Tensei nature and his objective of taking the Sharingan held by Danzō. 20 21

After obtaining multiple skins and assigning them to clones, Gen establishes the prototype of Genkyo, an organization operating through identities including Uchiha Gen, Hyuga Mokujin, and Bone Lord. 50

While acting as Reikawa, Gen is drawn into a memory of the Uzumaki Clan shortly before its destruction. There, the clan elders recognize him as their strongest member and entrust him with relocating the clan’s civilians amid an approaching war. 107 109 110

Gen discovers that the supposed jōnin Ito is a White Zetsu impostor, persuades the elders to abandon a passive escape plan, and prepares the Uzumaki Clan to fight its attackers. 111

Following Orochimaru’s release of the souls sealed within the Death God, Gen becomes involved with the reanimated First, Second, and Fourth Hokage. He withholds the fact that he founded Genkyo, while working with them against the escalating Akatsuki threat. 145 147 148

As Gen’s recovered memories and those of his skins continue to overlap, he increasingly questions the circumstances of his former death and the system’s true nature. 197 226

Appearance

Gen’s appearance changes frequently because of his system-provided skins, disguises, and clone identities. His original restored face retains visible cracks associated with his Impure World Reincarnation body. 12 17

• His initial identity, Jiya, has an ordinary-looking face and wears an Otogakure forehead protector around his left arm. 2
• His original/restored appearance has long black hair and a cracked face. 12
• As Uzumaki Reikawa, he has long red hair and resembles a healthy version of Nagato. 20
• His Shikotsumyaku skin gives him pale skin, short white hair, green eyes, and visible bone spurs. 46 50
• As Mirror/Kagami, he wears a mask while using an Ice Release skin. 59 60
• He often wears masks to conceal the cracks on his Edo Tensei body. 37
• He also uses white masks to conceal the identities of Genkyo operatives and the reanimated Hokage accompanying him. 149

Personality

Gen is eccentric, theatrical, and prone to treating dangerous situations with flippancy. He openly describes his former self as a “drama queen” with mild persecutory delusions, and his behavior often leaves others convinced that he is unstable. 2 3 4

Despite his manipulative streak, he repeatedly shows restraint toward people he considers unfortunate or vulnerable. He buys food for the Sound trio, worries about Dosu Kinata’s fate, gives snacks to Konohamaru’s group, and refuses to immediately take Sasuke’s eyes even when doing so would advance his own objective. 2 4 7 13

He is highly practical about survival and money. Gen steals Orochimaru’s equipment for resale, exploits gambling pools with foreknowledge, and considers bounty hunting and robbery as potential sources of income. 3 8 18 43

Gen’s casual persona conceals a protective instinct. During the Uzumaki Clan memory, he accepts responsibility for Kushina’s safety, shields her from attacks, and refuses to leave her with an injured relative despite the tactical inconvenience. 112 113 115

He is also increasingly troubled by the coexistence of the dead and living, as well as the uncertainty surrounding his own death and identity. 193 220 226

Abilities & Skills

Sharingan

Gen initially possesses a Three-Tomoe Sharingan, which he uses for genjutsu, perception, and combat prediction. The system later allows him to awaken the Mangekyō Sharingan. 2 22

• Places Kabuto under genjutsu and approaches him unnoticed. 1
• Controls a Root ninja during his infiltration of Danzō’s hideout. 21
• Uses Sharingan-based perception to manipulate shuriken and seemingly slow time during his clash with Jiraiya. 15
• Is vulnerable to powerful genjutsu despite his Edo Tensei body; he specifically recognizes Itachi’s sealing and genjutsu as serious threats. 13
• Uses his ocular perception to locate hidden people and detect threats before they strike. 113 294

Mangekyō Sharingan

Gen’s Mangekyō Sharingan was awakened through the system rather than the ordinary Uchiha process. Because he is an Impure World Reincarnation body, he does not face the usual risk of blindness from using it. 22

• Left Eye: Instantaneous Shift — Records Gen’s current state and location, allowing him to reverse to the recorded point at a chosen time. 22
• Right Eye: Susanoo — Amplifies an ability used through Susanoo by tenfold. 22
• Uses the Mangekyō’s restoration effect to recover chakra and undo injuries sustained during the Uzumaki Clan battle. 114
• Evades Tobirama’s Flying Thunder God attacks with a movement speed Tobirama judges to be nearly instantaneous. 193

Genjutsu

Gen’s genjutsu is effective enough to incapacitate opponents without direct combat.

• Catches Kabuto off guard during Orochimaru’s test. 1
• Subdues casino thugs after they target him. 8
• Breaches Sunagakure’s defenses by placing several guards under genjutsu. 27
• Uses genjutsu while infiltrating and gathering intelligence rather than relying solely on lethal force. 9 27

Susanoo

Following his Mangekyō awakening, Gen can manifest a black Susanoo, making his true nature difficult for others to assess. 22 23

• Uses a black Susanoo against Obito. 28
• Defeats Five-Tails jinchūriki Han with a single empowered Susanoo strike. 35
• Provides defense beyond the utility of Rotation. 46
• Enhances Adamantine Sealing Chains into sixteen chains during his confrontation with Kakuzu and Hidan. 42

Adamantine Sealing Chains

Through his Uzumaki-type skin, Gen gains Adamantine Sealing Chains and uses them as both restraints and defenses. 20

• Captures Kakuzu and Hidan while demanding signatures. 43
• Combines the chains with Rasengan against Chiyo’s puppets. 76
• Destroys six of Chiyo’s puppets; once a puppet is bound, it is effectively disabled. 78
• The chains have a brief vulnerability when deactivated, allowing Kakashi to strike him. 79
• Uses the chains at full power to kill enemy shinobi and rescue Uzumaki clansmen during the attack on the Uzumaki compound. 114

Instantaneous Shift

Gen’s Instantaneous Shift allows him to evade attacks, return to recorded states, swap with clones, and reposition across great distances. 22 23

• Escapes Danzō’s final attack. 23
• Uses a recorded state and clone swap to evade the consequences of Kotoamatsukami. 23
• Appears directly before Sunagakure’s conference table, bypassing its preparations. 27
• Uses clones and skin disguises to misdirect White Zetsu surveillance. 52
• Rewinds after exhausting large amounts of chakra during the Uzumaki Clan battle, restoring himself to a prior state. 114
• Transports Hashirama over long distances by maintaining physical contact with him. 235

Clones and Identity Network

Gen creates and coordinates clones that can wear separate skins and operate under independent identities. 15 50

• Uses clones for reconnaissance, missions, and misdirection. 50 52
• Maintains identities including Hyuga Mokujin, Bone Lord, Uzumaki Reikawa, and Kagami simultaneously. 50 60
• Uses a clone to remain with Akatsuki while his main body departs via Instantaneous Shift. 37
• His clone’s exposure contributes to the revelation that Gen is a reanimated body. 54
• A clone equipped with the Uzumaki-type skin can use its sealing techniques, though Gen’s main body then loses access to them. 23
• His clones do not benefit fully from Instantaneous Shift’s restoration effect and cannot replenish their chakra through a recorded state. 114

Shikotsumyaku

Gen gains the Shikotsumyaku bloodline through a system skin. 50

• Dance of the Seedling Fern — permanently added to his skill set. 50
• Ten-Finger Drilling Bullets — permanently added to his skill set. 50
• Forms bone spikes from his limbs for offense and defense, including bone-coated kicks capable of shattering another Kaguya clansman’s defensive bones. 208

Ice Release

Through the Mirror skin, Gen can use Ice Release and create reflected ice clones. 59 65

• Ice Mirror Clone — Produces an ice duplicate of a reflected target that possesses the target’s abilities, provided they do not exceed Gen’s own power. 65
• The copied clones are fragile and disappear once their ice bodies are shattered. 65

Impure World Reincarnation Physiology

As a reanimated body, Gen can regenerate from damage, reattach severed parts, and survive injuries that would be fatal to a living shinobi. 8 23

• Reattaches his severed arm after the battle with Danzō. 23
• Removes his own head repeatedly during his confrontation with Tobirama to demonstrate his resolve. 192
• His Edo Tensei body provides effectively inexhaustible chakra recovery, but its chakra capacity is limited; he cannot reliably sustain multiple high-output techniques at once. 215

Other Ninjutsu

• Shuriken Jutsu — used alongside Sharingan perception. 2 15
• Body Flicker Technique — part of his initial listed abilities. 2
