History

Shu’s Appointment and Retsu’s Resistance

Kagami Uchiha supported Shu Shiraishi’s appointment as Third Hokage when Hiruzen Sarutobi challenged it. Drawing his short blade alongside Torifu Akimichi, Kagami cited both Tobirama’s decision and Shu’s rescue of their group at Lightning Cloud Ravine. He regarded Shu’s overwhelming strength as a means of raising the Uchiha’s standing 3.

The clan’s established leadership was less receptive. At his first leadership meeting, Shu ordered the Uchiha to operate the western steel mill, using Fire Style in blast-furnace shifts. His wider reforms demanded seventy percent of clan treasury assets and all secret-technique scrolls. Retsu outwardly complied but privately declared that the Uchiha would never submit to a commoner 8 11.

Having overheard Retsu, Shu entered the Uchiha compound by destroying its gate. Retsu attacked with Fire Style: Majestic Destroyer Flame, but Shu dispersed the technique with a punch and slammed him into the courtyard paving. The clan’s strongest grand elder was left barely alive, and the assembled clansmen and police officers did not intervene 12.

Formation of the Urban Management Brigade

Shu appointed Kagami clan head and replaced the Military Police Force name with Urban Management Brigade. Rather than assigning every Uchiha to furnace work, he made their Sharingan central to supervising construction labor 13.

The brigade received authority to punish workers without prior ANBU approval, including whipping those who failed to use chakra and breaking the limbs of resisters. This removed restrictions that had previously forced Uchiha police to defer to powerful clans. More than a hundred Uchiha knelt and swore loyalty to Shu after the announcement 13.

The brigade then became an instrument of Shu’s internal consolidation:

• Sarutobi asset seizure: Kagami led 130 Uchiha against the Sarutobi Chamber of Commerce during its supply blockade. They defeated the guards, opened the granary, and confiscated supplies, money, and records under Shu’s nationalization order 17 18.
• Public purge: Uchiha officers seized three opposing clan elders at a mass gathering and carried out their execution 26.
• Construction enforcement: Sharingan-equipped overseers monitored laborers and drove the Akimichi to complete the heavy-industry base’s foundations and steel framework 28 31.
• Laboratory security: Shu ordered Kagami and four officers to burn six surviving attackers in blast furnace No. 1 after a sabotage attempt 40.

Industrial Work and Mechanized Warfare

Despite Shu’s initial reprieve from universal furnace duty, Uchiha elites were subsequently assigned to steel production. Their combined Great Fireballs could not reach the temperature required for special alloy steel. Shu forced Uchiha Tai to reveal his concealed Mangekyō Sharingan and use Amaterasu as the furnace’s heat source, while other Uchiha supplied coal and regulated airflow with Wind Release. The operation produced a reinforced-steel slab more than ten tons in weight 30.

The clan also became part of Konoha’s weapons industry. Sharingan users inspected products for defects, and Uchiha craftsmen later worked alongside Hyūga craftsmen on aircraft construction 43 82.

When Kumogakure invaded, Kagami mobilized more than three hundred Uchiha for the Heavy Machine Gun Battalion. The defensive line deployed three hundred Chakra Maxim guns; its opening barrage destroyed the thousand-ninja vanguard in one second. Uchiha officers subsequently restrained the captured Third Raikage and helped secure the prisoners 44 45 46 50 51.

Security and Expansion Campaigns

The brigade retained its policing role as its equipment advanced. Kagami captured Hiruzen for Shu’s public trial, while Uchiha officers later subdued Sasori and confiscated his poison and puppet scrolls 58 59 71.

Uchiha personnel also served at the East Sea shipyard. Kagami received Shu’s test call on the first mobile Chakra terminal and reported on aircraft-carrier construction 86.

During the Land of Wind campaign, hundreds of Uchiha boarded armored vehicles carrying Chakra rifles and fragmentation grenades. After Sunagakure surrendered, the brigade entered with electrified batons and processed the defeated ninja. An Uchiha officer reported that the village had been occupied in less than two hours 106 112.

At the later Kirigakure blockade, an Uchiha pilot shot down a seagull attempting to escape the encirclement. Following the Third Mizukage’s surrender, Uchiha troops boarded the flagship and began fitting captured ninja with electronic ankle shackles 121.

Organization and Authority

Notable Members

Abilities & Skills

Sharingan

• Movement and chakra observation: Detects slight movements and chakra flow, allowing overseers to judge whether workers are properly applying their techniques 13.
• Quality inspection: Used to identify defects on Konoha’s industrial production lines 43.
• Vehicle operation: Uchiha drivers activate their Sharingan while monitoring armored-vehicle instruments 106.
• Documented limit: Kagami’s Three-Tomoe Sharingan could not resolve the individual bullet paths during the first Chakra heavy-machine-gun test; he perceived only a blue line 33.

Fire Style

• Great Fireball Technique: Used collectively to melt the Sarutobi granary’s locks, heat industrial furnaces, and test Chakra Mecha armor 17 30 41.
• Majestic Destroyer Flame: Retsu’s advanced technique produced a fan-shaped blaze more than ten meters high and twenty meters wide 12.
• Industrial limit: The furnace team’s Great Fireballs reached approximately 1,200 degrees, insufficient for Shu’s required special alloy steel 30.

Mangekyō Sharingan

• Amaterasu: Tai’s right eye produces black flames hot enough to extract molten iron from ore within seconds 30.
• Cost: Tai suffers severe pain and bleeding when using the technique; repeated Mangekyō use threatens his eyesight 30.
• Kotoamatsukami: Shisui’s stolen eye contains this genjutsu. Danzō attempts to use it to command a Chakra Mecha guard; the supplied account does not establish a successful result 89.

Supporting Ninjutsu and Combat

• Wind Release: Some Uchiha regulate furnace air pressure and help prevent Amaterasu from destroying the kiln 30.
• Close combat: Kagami uses the Body Flicker Technique and physical strikes to overwhelm a Sarutobi guard during the warehouse raid 17.
• Modern weapons: Clan personnel operate machine guns, carry rifles and grenades, and crew armored vehicles rather than relying solely on conventional ninja tools 44 106.

Uniforms, Insignia & Equipment

• Clan crest: A red-and-white fan marks the compound’s entrance and the former police uniforms 12.
• Police uniform: High-collared clothing worn by the compound guards before reorganization 12.
• Brigade uniform: Short black outfits with red cloth tied around the right arm; the earliest strips served as temporary insignia 17.
• Industrial protection: Gray fireproof suits for furnace crews and gas masks for officers working during Chiyo’s poison-mist attack 30 56.
• Early enforcement weapons: Standard straight swords and meter-long jujube-wood clubs 17.
• Upgraded weapons: Chakra submachine guns, heavy rifles, fragmentation grenades, and electrified batons. Kagami also carries a wired vibrating straight sword 51 58 106 112.
• Prisoner restraints: Chakra Suppression Collars reduce prisoners to twenty percent of their chakra and threaten lethal punishment for resistance; later operations use electronic ankle shackles 51 121.

Relationships

• Shu Shiraishi — Overlord and patron. He forcibly removes Retsu, installs Kagami, and exchanges obedience for extensive enforcement privileges 12 13.
• Sarutobi Clan — Rival whose political influence previously constrained Uchiha policing. The brigade enthusiastically carries out the confiscation of its commercial assets 13 17 18.
• Akimichi Clan — Major target of construction oversight. Uchiha officers enforce the use of enlargement techniques for foundation work and steel handling 28 31.
• Hyūga Clan — Fellow industrial workforce. Their detection assignments complement Uchiha steelmaking, and craftsmen from both clans participate in aircraft construction 16 82.
• Shimura Danzō — Secretly stole Shisui Uchiha’s eye years before attempting to use its Kotoamatsukami against a Chakra Mecha 89.
