Libra Dōko, the Gold Saint of Libra, serves as both mentor to Dragon Shiryu and a seasoned survivor of the prior Holy War alongside Aries Shion. Though over 260 years old, his youthful appearance reflects mastery of cosmic energy and the Eighth Sense, which transcends mortal limits. After training in Rozan’s Five Old Peaks, he remained there as a hermit, honing Shiryu’s skills in techniques like the Rozan Hyakuryu Ha, a dragon-summoning strike demanding flawless cosmic precision. When Hades’ forces resurged, Dōko abandoned his seclusion to confront the threat, reuniting with Shion—now resurrected as a Specter. Their clash revealed unspoken trust, with Dōko discerning Shion’s enduring loyalty to Athena beneath his undead guise. The duel strategically stalled enemies to aid Shiryu and Mu’s advance, ending in a solemn farewell as Shion’s soul found peace. Dōko’s wartime expertise guided the Saints to awaken the Eighth Sense for entering the Underworld, while his plan to shatter the Wailing Wall with united Gold Cloths averted Shaka’s sacrificial fate. His Libra Cloth conceals twelve peerless weapons—swords, shields, and polearms—whose combined might eclipses that of all Gold Saints. These armaments proved vital in demolishing divine constructs, from Poseidon’s oceanic pillars to Hades’ barriers. During the conflict’s climax, Dōko’s rejuvenated form displayed undiminished skill, leaving allies awestruck. Spin-offs *Saint Seiya: The Lost Canvas* and *Next Dimension* expand his history, depicting him and Shion as 18th-century comrades who breached Elysium to challenge Hades, allying with Pegasus Tenma. Their bond underscores tactical synergy and shared resolve, with Dōko balancing idealism with pragmatism. *Next Dimension* reinforces his legacy by featuring his younger self as the Libra Saint in the same era. Dōko’s influence endures through Shiryu, whom he molded to inherit the Libra mantle. This mentorship underscores his lasting impact on Sanctuary’s defenders. His strategic brilliance, cosmic mastery, and unwavering devotion to Athena cement his role as a linchpin across Holy Wars, bridging eras through wisdom and sacrifice.
