Background

Kazuna was one of Konoha's three celebrated young shinobi during the Third Shinobi World War, alongside Minato Namikaze and Shisui. Known as Blood Flame Kazuna, his blood-red Fire Release incinerated numerous enemies and was regarded as extraordinary even among elite shinobi 1.

On the eve of Konoha's victory, he was accused of abandoning his comrades to complete a mission. The scandal brought universal condemnation and drove him into an apparently aimless retirement inside the Uchiha compound, where he spent his days drinking tea, carrying a birdcage, and wandering the grounds 1. Shisui, however, remained convinced that Kazuna was incapable of the betrayal attributed to him 1.

During his retirement, Kazuna quietly studied nearly every member of the Uchiha clan and cultivated extensive prestige among its younger generation. He concluded that Uchiha politics could only be shaped through strength, then used his Mangekyō Sharingan, allies, and political maneuvering to challenge Fugaku's authority 4 10.

Appearance

Kazuna is first depicted in dark clothing with a small katana carried across his back 1.

• Usually maintains a relaxed, unhurried bearing, even in politically charged or dangerous situations 1 34.
• His Fire Release is distinguished by its thick, blood-red coloration 1.
• His Mangekyō Sharingan and later Rinnegan are central to his intimidating presence 10 368.

Personality

Kazuna presents himself as lazy, unserious, and carefree, often drinking tea or making jokes while others panic around him. His casual behavior masks a highly observant strategist who tracks clan affairs, understands individual personalities, and influences decisions from behind the scenes 1 10.

He is provocative and enjoys verbally needling opponents, particularly Danzō, Hiruzen, Fugaku, Obito, and Madara. He also consciously manages his reputation among the Uchiha through propaganda and personal encouragement, building a devoted following within the clan 13 130 174.

Despite his ambition and willingness to manipulate or intimidate others, Kazuna consistently warns the Uchiha against initiating civil war. He views Konoha's stability as necessary to protect the clan from the other villages and favors gradual consolidation over reckless rebellion 36.

Abilities & Skills

Sharingan and Mangekyō Sharingan

Kazuna is a Mangekyō Sharingan user whose ocular power forms the core of his combat style and political authority.

• Uses the Mangekyō's pressure to force compliance from Uchiha elders and jonin 10.
• Capable of powerful genjutsu; Orochimaru acknowledges that Kazuna can control people through his eyes 210.
• Advances to the Eternal Mangekyō Sharingan and eventually manifests dual Rinnegan 289 368.
• Can perceive and counter threats such as Obito's ambushes and hidden surveillance 46 130.

Zero Realm

Kazuna's left-eye Dojutsu is Zero Realm, born from his fear of Shisui's Kotoamatsukami.

• Nullifies all Dojutsu effects, including Kotoamatsukami 60.
• Allows him to use his Mangekyō with less concern for ocular techniques used against him 60.
• Does not prevent ordinary ninjutsu, physical attacks, or battlefield-scale damage.

Right-Eye Spiritual Dojutsu

His right eye gradually influences a target's existing emotions and inclinations.

• Suggests actions and can slowly amplify admiration into loyalty 102.
• Was used to influence Pakura into attacking the Uchiha compound 102.
• Works as subtle infiltration rather than immediate, absolute domination like Kotoamatsukami 102.
• Requires a pre-existing emotion or repeated contact to strengthen its effect 102.

Susanoo

Kazuna's Susanoo is his principal large-scale combat construct.

• Defeated twenty Uchiha jonin and special jonin through Mangekyō Sharingan and Susanoo power 36.
• Used Red Magatama to annihilate Aburame Shikuroo and Root forces, leaving a massive crater 31.
• Assumed Yatagarasu Form to destroy Kusagakure shinobi 58.
• Developed further Susanoo and Yatengu forms after attaining LV·6 Dojutsu 130.
• Can combine with Hashirama's Wood Golem and later manifest as Six Paths-enhanced armor around his body 316 372.
• Sustained Susanoo use places a severe drain on his Chakra 119.

Fire Release and Blood Flame

Kazuna's signature Fire Release produces blood-red flames powerful enough to overwhelm conventional Uchiha techniques.

• Overpowered Fugaku's Great Fireball Technique with his Blood Flame 6.
• Uses Great Fireball Technique, Phoenix Sage Fire Technique, and Great Fire Annihilation 6 48.
• Employs Phoenix Sage Fire's broad range to pressure opponents with space-time abilities, such as Obito 48.
• His Blood Flame was considered one of the defining powers of Konoha's Third Shinobi World War generation 1.

Sage Art

Kazuna develops Sage Art through the Fruit cultivated by the Divine Tree within him.

• Reached LV·4 Sage Art by absorbing cultists' life energy 132.
• Can enter Sage Mode, though not as instantly as Hashirama 132 316.
• Shares Sage Art Chakra with allied shinobi during the battle against Madara 367.
• Combines Sage Art with Susanoo, tailed-beast Chakra, and Six Paths power 316 394.

Divine Tree, Fruit, and Immortal Body

Kazuna houses a Divine Tree that converts absorbed life energy into Fruits that strengthen his powers.

• Absorbs life energy from prisoners, animals, cultists, shinobi, and White Zetsu 82 107 132.
• Absorbed a hidden White Zetsu to strengthen the Divine Tree 48.
• Possesses an Immortal Body and can survive while drawing heavily on life energy 132.
• Uses unripe Fruit to replenish Chakra during combat 119.

Tailed-Beast Power

Kazuna commands immense tailed-beast-related power.

• Defeated the Three-Tails through direct physical force and Susanoo 219.
• Controls the Nine Tailed Beasts by the time Madara returns to the battlefield 324.
• Uses a Nine-Tails Tailed Beast Transformation against Madara 364.
• Shares Nine-Tails Chakra with allied shinobi during the final war 367.
• His later Susanoo-tailed-beast construct resembles a ten-tailed creature built around the Nine-Tails 394.

Ninjutsu, Sealing, and Summoning

Kazuna possesses a broad ninjutsu repertoire beyond his ocular abilities.

• Shadow Clone Technique — Creates multiple clones for combat, suppression, and Chakra distribution 48 367.
• Body Flicker Technique — Moves quickly enough to repeatedly evade the Raikage's full-powered attacks; he claims the “Body Flicker” title should belong to him rather than Shisui 241.
• Totsuka Blade — Seals Hashirama and Tobirama's Impure World Reincarnation bodies 289.
• Impure World Reincarnation — Commands reanimated historic figures, including Hashirama, Madara, Nagato, Tobirama, and Minato 401.

• Totsuka Blade — A sealing weapon wielded through Susanoo against Hashirama and Tobirama 289.
• Akatsuki ring — Used for contact with other Akatsuki members 153.

Relationships

• Uchiha Shisui — Close friend and trusted subordinate. Shisui believed Kazuna was innocent of abandoning his comrades; Kazuna later entrusted him with clan welfare funds and elevated him to Hokage Assistant and captain of his guard 1 10 212.
• Uchiha Fugaku — Kazuna's father and initial political rival within the Uchiha. Their conflict gives way to a division of authority, with Fugaku overseeing internal security while Kazuna takes charge of external affairs and the Military Police Force 46 255.
• Uchiha Itachi — Kazuna's disciple and intended successor. Kazuna relies on him for intelligence work while grooming him to eventually inherit leadership 25 174 377.
• Shimura Danzō — Persistent enemy. Danzō repeatedly tries to eliminate Kazuna through Root operations and later openly attacks the Uchiha, while Kazuna exploits Danzō's reputation and defeats his forces 13 31 182.
• Obito Uchiha — Rival, occasional collaborator, and repeated assassination target. Kazuna recognizes Obito's identity, counters his ambushes, and reaches a tense cooperation with him 37 48.
• Pakura — Initially manipulated by Kazuna's right-eye Dojutsu; later becomes an ally whose assistance supports the plan to assassinate Rasa 102 126.
• Kakuzu and Hidan — Subordinates whose loyalty Kazuna tests and controls through his Mangekyō. He assigns Kakuzu secret missions and uses both in his broader operations 55 120.
• Karin Uzumaki and Uzuki Uzumaki — Rescued from Kusagakure and brought to Konoha after witnessing Kazuna's Susanoo. Their Uzumaki vitality becomes a concealed source of recovery for him 58 175.
• Kakashi Hatake — Initially manipulated by Kazuna, who secretly replaces Kakashi's Sharingan with a fake; later selected for the Hawk Squad 87 212.
• Kaguya Ōtsutsuki — Initially a potential enemy, later summoned by Kazuna and drawn into an alliance against Hagoromo and the Ōtsutsuki threat 372 401.
• Hashirama Senju — Powerful battlefield ally against Madara and the Sage of Six Paths; together, they fuse Wood Golem and Susanoo 316 341.
• Madara Uchiha — One of Kazuna's greatest rivals. Kazuna respects Madara's historic strength but repeatedly confronts him through the final war 312 364.

Story Role / Major Arcs

Uchiha Political Takeover

Kazuna returns from retirement as an influential force within the Uchiha. Through Yashiro's proposal, Mangekyō intimidation, and a challenge to Fugaku, he becomes Vice Clan Leader, Deputy Head of the Security Force, and head of the Konoha Military Police Force 4 5 15.

He restructures the clan's barriers, sentries, patrols, and police priorities. He also provides high-level ninjutsu scrolls and 500 million ryo for vulnerable Uchiha members, improving the clan's living conditions and military strength 10 130.

Root Conflict

Kazuna deliberately draws Root into attacking him, then defeats its operatives in the Forest of Death. His destruction of Aburame Shikuroo's unit with Susanoo and Red Magatama turns Danzō's assassination attempt into a political embarrassment 26 31.

Akatsuki and Tailed-Beast Operations

Kazuna joins Akatsuki while openly proposing the capture of tailed beasts. Pain and Obito regard his knowledge and ambition as dangerous, while Konan chooses to cooperate with him 143.

He later defeats tailed beasts directly, acquires influence over the Nine Tailed Beasts, and develops his own tailed-beast transformation 219 324 364.

Hokage Leadership

As Hokage, Kazuna establishes the Hawk Squad to pursue Akatsuki-affiliated S-rank rogue ninja. He appoints Shisui as Hokage Assistant and directs Jiraiya to train Naruto in controlling the Nine-Tails 212.

His administration expands Konoha's influence, supports shinobi education, channels resources to the next generation, and turns the Uchiha into Konoha's dominant clan 200 220.

Final War and Six Paths Conflict

Kazuna fights Madara, Obito, the tailed beasts, and eventually Hagoromo. He distributes Sage Art and Nine-Tails Chakra to the Allied Shinobi Forces, gains dual Rinnegan, and reveals power that Madara had inexplicably overlooked 367 368.

After summoning Kaguya as a Summoning Beast, Kazuna defeats and kills Hagoromo. He then seals the Sage of Six Paths and drains his sealed power as a reserve against the Ōtsutsuki Clan 401 404.
