Libra Dohko, revered as Roushi (Old Master), stands as one of only two survivors from the 18th-century Holy War against Hades, alongside Aries Shion. His path began as a Bronze Saint training in China's Lushan mountains under an ancient master who had transformed into a dragon after succumbing to grief. This draconic mentor taught Dohko the formidable Rozan fighting techniques before ascending to the stars. After the war, Athena bestowed upon Dohko the divine technique Misopetha-Menos. This power drastically slowed his aging by reducing his heartbeats to roughly 100,000 per year – equivalent to a single day in an ordinary human life. Consequently, 243 years felt merely like 243 days to him. Charged with guarding the seal imprisoning Hades' 108 Specters, he remained stationed at Mount Lu's Five Old Peaks in China. While the technique altered his outward appearance to that of a diminutive, elderly man with purple skin and white hair, he retained his original youthful vitality internally. During his centuries-long vigil at Mount Lu, Dohko mentored Dragon Shiryu as his primary disciple, though he also trained others like the anime-exclusive Ohko and the *Lost Canvas* character Tenma. He distanced himself from the Sanctuary, suspecting his former comrade Shion, the Pope, had been replaced by an imposter – a suspicion tragically confirmed when Gemini Saga murdered Shion and usurped the papal throne. In the *Hades Chapter - Sanctuary* arc, Dohko confronted the resurrected Shion, who was manipulated by Hades into attacking Athena. Their battle reached a stalemate as Dohko unleashed his Rozan Hyaku Ryū Ha against Shion's Stardust Revolution. To combat the crisis, Dohko sacrificed his aged form by reversing the Misopetha-Menos technique, permanently restoring his youthful body. He subsequently organized the surviving Gold Saints to breach the Wailing Wall, culminating in their collective sacrifice to destroy it. Dohko's combat mastery centers on Rozan martial arts, featuring techniques like Rozan Shō Ryū Ha (Rising Dragon Punch) and Rozan Hyaku Ryū Ha (Hundred Dragons Attack), which unleashes dragon-shaped cosmic energy. He also commands the twelve weapons of the Libra Gold Cloth, capable of splitting mountains and freezing coffins. His strength ranks as the greatest among the Gold Saints, enabling him to withstand galaxy-level assaults like Shion's Stardust Revolution. Spin-off media expands his earlier life: *Next Dimension* depicts his impulsive youth during the 18th-century war, defying orders to investigate Hades' incarnation with Shion and Tenma. *The Lost Canvas* shows him undertaking missions in Italy, training Tenma, and ultimately sacrificing himself to delay Hades during the invasion of Sanctuary, though he is later revived. Personality-wise, young Dohko was brash and rebellious. Centuries of guardianship cultivated a serene, philosophical demeanor emphasizing meditation, cosmic balance, and pacifism, though he could revert to youthful vigor when necessary. His profound wisdom established him as a revered figure among Saints and a strategic leader after Saga's defeat.
