History

Standing Before the Massacre

The Uchiha were a distinguished clan dating back to Konoha’s founding. The Second Hokage, Tobirama Senju, established the Konoha Military Police Force and placed it entirely under their control. The account describes this arrangement as a means of concentrating the clan where it could be monitored 16 37.

Relations with the village leadership deteriorated over opposition within the clan. Hiruzen later stated that an earlier plan had involved Shisui using Kotoamatsukami on Uchiha Fugaku and opposing clansmen. Danzo instead seized Shisui’s eye and collected Sharingan from Uchiha victims 47.

Clan Massacre

Itachi directly carried out the massacre, killing Sasuke’s parents and the other clansmen in the compound. Xia Yu survived because he was elsewhere that night; Itachi did not find him and did not search the village afterward. Xia Yu and Sasuke became the two Uchiha remaining in Konoha 1 3 11 34 42.

The victims’ bodies and eyes were subsequently exploited. Danzo supplied Sharingan to Orochimaru, who instructed Kabuto to transplant them into Shin for cloning research. Danzo also implanted stolen Sharingan into his own arm 4 47.

Rebuilding Through Marriage

Xia Yu secured Hiruzen’s approval to take multiple wives and concubines specifically to restore the Uchiha population. As part of the settlement over the clan estate, he requested ten percent for himself, forty percent for Sasuke, and fifty percent for Konoha as a protection fee 3.

He then posted recruitment notices throughout the village and invited applicants into the compound. Sasuke initially regarded this as a disgrace, but accepted Xia Yu’s argument that population, commerce, resources, and influence were essential to the clan’s survival. Their responsibilities separated: Sasuke would pursue revenge, while Xia Yu would rebuild the family 10 12 13.

An enormous wedding brought Hiruzen and Konoha’s clan representatives to the compound. More than half a year later, the first births began. Sasuke took extended leave from the Ninja Academy to help direct the nannies caring for the newborns 16 17.

Confrontation with Danzo

Root’s attempt to assassinate Xia Yu exposed the strength he had gained through the births. His gigantic Great Fireball and subsequent Susanoo transformed the confrontation into a village-wide spectacle. He exposed Danzo’s Sharingan-covered arm and later reclaimed Shisui’s stolen eye 18 21 22 24.

Public discussion turned against Danzo and increasingly favored Xia Yu. Hiruzen nevertheless prevented Danzo’s transfer for interrogation and confined him under medical supervision. Danzo later demanded another Uchiha massacre, explicitly including Sasuke; Hiruzen killed him during their confrontation 24 33 47.

Restoration of Police Authority

Xia Yu agreed that the clan would stop pursuing the Danzo affair and requested the return of the Konoha Military Police Force. Kurenai declared herself an Uchiha member, and Xia Yu argued that his ninja wives could staff the force until the children grew up. Hiruzen approved the restoration 37.

The restored department was staffed almost entirely by Xia Yu’s wives, with Special Jonin Anko in charge. Hiruzen continued monitoring it through Anbu and separately assigned Yugao to infiltrate Xia Yu’s household 37 48.

Xia Yu also privately recruited Itachi’s cooperation. Rather than demand immediate revenge, he offered Itachi an opportunity to atone by continuing to protect Konoha from the shadows—this time in support of the Uchiha’s future 42.

Abilities and Skills

Sharingan and Mangekyō Sharingan

• The clan’s ocular abilities are a major target of theft and experimentation, including Danzo’s implants and Orochimaru’s cloning research 4 47.
• Mangekyō users develop special abilities in their left and right eyes; Xia Yu’s effects differ according to the target’s sex 27.
• Xia Yu’s five-second ocular effect causes severe kidney damage in men or pregnancy with his child in women. The female effect also causes temporary pain, weakness, paralysis, and inability to mobilize chakra 27 28.
• Xia Yu’s claimed ability to “See Through Everything” is a deception used to conceal the true source of his knowledge and powers 42 48.

Susanoo

• Xia Yu states that awakening Mangekyō in both eyes permits the use of Susanoo 48.
• His blue manifestation withstands Danzo’s kunai without damage; the weapon breaks against it 22.
• Itachi’s existing Mangekyō prowess and Xia Yu’s emergence as another Susanoo user attract Orochimaru’s attention 33.

Fire Release

• Fire Release is an expected Uchiha skill: Xia Yu’s inability to perform even its basics contributes to his early reputation as a clan disgrace 1.
• Xia Yu’s system-granted repertoire includes Great Fireball, Great Fire Dragon, Great Fire Annihilation, and Searing Migraine 16 17 30.
• His meteor-sized Great Fireball requires more than thirty Root ninja using water techniques and scrolls to extinguish it 18.

Territory, Customs, and Resources

• Commerce — Women joining Xia Yu relocate businesses into the compound, including flower, dango, barbecue, and dumpling shops 10 16.

• Clan crest — The distinctive emblem on Sasuke’s shirt immediately establishes his Uchiha identity to the recruitment applicants 12.
