Hizashi Hyūga

Anyone who knew Hiashi would have recognized his twin at a glance, since the two men shared one face apart from the branch seal marked across Hizashi's brow. His hair fell long and black, and his pupil-less white eyes matched every relative of his bloodline. Off duty he favored a loose, long-sleeved kimono cinched with an obi, the informal dress common across the clan, while missions called for a plain black getup layered over mesh mail, his dark headband, and a waist sash. Once he stepped into his brother's place, he switched to Hiashi's look: a pale kimono knotted with a dark sash beneath a brown, long-sleeved haori. The anime also slots him into Tsunade's Infinite Tsukuyomi dream as a masked figure from Jiraiya's novel, wearing an orange swirl mask over a plain black kimono.

The Will of Fire burned genuinely in Hizashi, even as resentment toward the main household simmered underneath. He came to regret letting that bitterness color his son's view of the family, yet his devotion to the Hyūga never wavered. When the moment demanded it, he surrendered his own life without pause, both to keep the Byakugan's secrets buried and to spare his brother from death.

Hizashi arrived only moments behind Hiashi, and that thin margin of time decided everything: his brother inherited leadership of the clan while Hizashi was placed in the branch family. A cursed marking was later burned onto him, a seal that guaranteed lifelong obedience to the main line and would blank out his Byakugan upon death. He loathed the arrangement but saw no escape and endured it. In time he raised a son, Neji, and when Hiashi's daughter Hinata reached her third year, custom dictated that Neji too receive the same brand. Watching the boy display prodigious talent while the heiress faltered, Hizashi grew openly resentful, his frustration eventually sharpening into killing intent. Hiashi felt it and triggered the seal in reprimand, wracking his twin with agony and planting the first seeds of Neji's distrust toward the main house.

The turning point came with the incident remembered as the Hyūga Affair. To rescue Hinata, Hiashi slew Kumogakure's head ninja, and Kumo demanded his corpse in return, secretly hunting the Byakugan's secrets. The clan elders and Konoha's leaders proposed sending Hizashi in his place, a substitution that would shield the clan's leader and lock away the dōjutsu's mysteries at once. Hizashi consented. When Hiashi objected, a single strike from his brother left him unable to move, and Hizashi explained that his choice served neither the clan's hierarchy nor its duty: he acted to keep his brother alive, to head off war, and, for once, to decide his own path. His final request was that Hiashi someday tell Neji the true reason, since he had only ever let the boy witness his bitterness.

Little of his combat record survives, though every sign marks him as a capable shinobi; Neji judged his father roughly a match for Hiashi in raw power, and his renown was strong enough that Kabuto Yakushi revived him during the Fourth Shinobi World War. Like all of his kin he wielded the Byakugan and the Gentle Fist, refined enough to freeze his brother with a single blow. Brought back through the Impure World Reincarnation, he clashed with the Allied Shinobi Forces and faced Hiashi once more, apologizing for standing as a foe before the two traded blows; Chōji's colossal butterfly form eventually pinned him. When the reincarnation jutsu was undone, his soul was finally freed.

His death reshaped those he left behind. The loss hardened Hiashi into a severe man convinced that only strength ensures survival, and though the sacrifice averted open war, ties between Konoha and Kumo stayed strained for years afterward. Neji, believing the main family had engineered his father's death, came to see fate as inescapable and scorned his relatives, until Naruto Uzumaki beat him at the Chūnin Exams and Hiashi at last revealed the truth. Following his father's example, Neji later chose his own end, dying to shield Hinata and Naruto during the very war his reincarnated father was reluctantly dragged into.
