Background / History

Yoru prevented the Uchiha massacre by secretly relocating the clan through his Mangekyō Sharingan's Space-Time ability. He argued that preserving the clan offered a better alternative than Itachi carrying out Konoha's extermination order, then revealed that the supposed coup had been a deception to move everyone into a new world. 2 4

Before the relocation, Yoru secretly rescued Shisui after his presumed death. He kept Shisui hidden for roughly half a year, partly to recover and partly to keep him from interfering with the clan's break from Konoha; Shisui eventually accepted Yoru's leadership. 4

In the Pirate World, Yoru chose Kuja Island as the Uchiha's first base because of its isolation in the Calm Belt. He forced a settlement agreement with Hancock, then secured Haki instruction for the clan through a series of exchanges and coercive leverage. 9 16 18

After the clan developed Haki and acquired Devil Fruits, Yoru led its return to Konoha. He divided the Uchiha into target-specific teams, overthrew the existing leadership, presented evidence of the former regime's corruption, and became the Fifth Hokage with the Fire Daimyo's recognition. 68 69 76 82 83

He later expanded his operations across worlds: he pursued Senjutsu at Mount Myōboku, sought control over major Pirate World figures and resources, and joined the Demon Slayer Corps with Itachi and Inabi to hunt demons and draw out Muzan. 96 100 90 92 112 114

Appearance

Yoru is a black-haired, black-clothed man with a calm, unassuming build and presence. In battle, his black pupils shift to crimson Mangekyō Sharingan. 58

• Black hair and black clothing. 58
• Crimson Mangekyō Sharingan when activating his ocular powers. 58
• Manifests a towering crimson Susanoo, later covered in black Armament Haki. 58

Personality

Yoru is composed, calculating, and exceptionally confident in his knowledge. He routinely conceals his true intentions, whether arranging the Uchiha relocation, negotiating with Kuja, or maneuvering political opponents. 4 17 76

His leadership is pragmatic rather than gentle. He is willing to deceive, threaten, and exploit personal weaknesses—including Hancock's past and Moria's attachment to his dead crew—when he believes it serves the Uchiha's future. 18 91

Despite this ruthlessness, Yoru consistently invests in his clan's survival and growth. He saved Shisui, arranged Haki training, distributed Devil Fruits, entrusted Itachi with the strongest fruit, and mentors Naruto and Inabi. 4 20 63 81 109

Abilities & Skills

Mangekyō Sharingan

Yoru possesses Mangekyō Sharingan in both eyes, granting him distinct Space-Time and prophetic powers. 3 17

• His left eye grants Amenomikado, a Space-Time technique that opens Dimension Gates between worlds. 3 17
• Amenomikado can transport large groups, though doing so heavily depletes his eye power. 4
• His right eye possesses the Earth Contract Seal, which attunes to a world's fundamental laws and analyzes its core power system. 17
• The right eye also gives him prophetic knowledge, including awareness of Obito's limits, Black Zetsu's identity, and Naruto's status as the Child of Prophecy. 3 100
• He can analyze Devil Fruits and perceive their abilities. 63

Genjutsu

Yoru uses Sharingan genjutsu for control, deception, and infiltration.

• Controlled Celestial Dragons and implanted a command in Saint Charlos to forget Yoru's involvement and abandon the investigation. 49 50
• Used the Transformation Technique to infiltrate Charlos's medical tent. 50
• Can influence and briefly control animals through ocular techniques, demonstrated through Salome and Dora. 16
• Uses psychological leverage as part of his negotiations, notably against Hancock. 18

Susanoo

Yoru's Susanoo surpasses those of Itachi and Shisui in scale and power. 58

• Manifests a colossal crimson Susanoo with wings and a massive Susanoo Sword wreathed in crimson flames. 58
• Coats the entire construct—including its armor, wings, and sword—in Armament Haki. 58
• Withstood Moria's Shadow Gathering-enhanced strike and defeated him with one Haki-coated Susanoo punch. 91
• Clashed with Akainu and forced the Admiral backward, though the attack did not defeat him. 58

Haki

Yoru acquired Haki through the Earth Contract Seal rather than conventional training. 17

• Uses advanced Armament Haki to reinforce his body, weapons, and Susanoo. 14 58
• Demonstrated sufficient physical reinforcement to catch Sanemi Shinazugawa's full-force Nichirin Sword strike with two fingers and snap the blade. 118
• Uses Conqueror's Haki to overwhelm and incapacitate large groups of weaker opponents. 74
• Exchanged Conqueror's Haki with Whitebeard, holding his own before ultimately losing the clash. 85

Sage Mode

Yoru trained at Mount Myōboku under Fukasaku and Shima. 97 100

• Initially struggled to absorb Natural Energy because his own physical and spiritual energy were too overwhelming. 98
• Solved this by absorbing the condensed Natural Energy within a Devil Fruit. 98
• Achieved a Sage Mode with no stated time limit and the ability to maintain it during battle. 98

Impure World Reincarnation

Yoru uses Impure World Reincarnation to summon and control the deceased. 78 90

• Summoned the Third Hokage to test the diminished strength of an Impure World body. 78
• Worked with Orochimaru to summon John, Blair, and Mary, using their return to recruit Moria. 90 91
• Summoned Crocodile in an attempt to gain control of Alabasta. 92
• Summoned Yoriichi Tsugikuni to fight Muzan in exchange for Yoriichi's chance at redemption. 119

Equipment / Weapons / Items

• Shusui — Ryoma's sword, retrieved from Thriller Bark and adopted as Yoru's personal weapon. 92
• Flame Gunbai — a weapon Yoru stores in a scroll due to its inconvenient size and visibility. 92
• Mount Myōboku Summoning Contract — signed to establish a connection with the toads of Mount Myōboku. 97

Relationships

• Uchiha Itachi — younger brother and key ally; Yoru persuaded him away from the massacre mission and later entrusted him with the strongest Devil Fruit. 2 63
• Uchiha Shisui — saved and concealed by Yoru; a loyal subordinate who supports his leadership and uses Kotoamatsukami at Yoru's direction. 4 82
• Uchiha Fugaku — father and senior clan figure; supports Yoru's leadership despite concerns over his methods. 4 69
• Uchiha Obito — adversary and later operative; Yoru exposed his identity and abilities, then sent him to spy on Nagato and Black Zetsu's forces. 3 90
• Boa Hancock — initially hostile counterpart on Kuja Island; Yoru negotiated the Uchiha settlement and Haki training through coercive exchanges. 15 18
• Naruto Uzumaki — Yoru's disciple; Yoru offered him acceptance and personal training after becoming Hokage. 81
