Capricorn Shura serves as the Gold Saint guarding the tenth zodiac temple, wielding the sacred sword Excalibur embedded within his limbs. Thirteen years prior, he participated in the attack on Sagittarius Aiolos under orders from the false Pope Saga, who concealed his identity after murdering the rightful Pope. Unaware the infant Aiolos protected was Athena, Shura inflicted fatal wounds during Aiolos's escape from Sanctuary.
In the original manga, Shura initially obeyed Saga, believing power inherently justified authority regardless of its morality. During the Sanctuary arc, he confronted Dragon Shiryu, demonstrating Excalibur's ability to shred bronze cloths and shatter shields. Their battle ended in mutual defeat as both ascended toward space. Facing death, Shura recognized Shiryu's unwavering dedication to Athena, repented his past actions, and sacrificed himself by transferring his gold cloth and Excalibur's power to Shiryu before kicking him to safety. The anime depicted greater initial loyalty to Athena, while the spin-off *Episode G* presented a reconciliation where Shura discovered Saga's treachery but fell under the mind-controlling "Demon Emperor Fist," forcing compliance while retaining inner loyalty.
Shura's spirit manifested during the Poseidon arc to guide Shiryu in activating Excalibur against Chrysaor Krishna, enabling the destruction of Krishna's lance and armor.
In *The Hades Chapter – Sanctuary*, Hades resurrected Shura alongside Gemini Saga and Aquarius Camus under a 12-hour life limit to assassinate Athena. While posing as traitors, their true intent was to reach Athena's side. They overwhelmed Aries Mu and confronted Virgo Shaka. Compelled by Shaka's Tenbu Hōrin technique, they reluctantly used the forbidden Athena Exclamation, killing Shaka. Later, facing Scorpio Milo, Leo Aiolia, and Mu, who countered with their own Athena Exclamation, Shiryu intervened. Shiryu reminded Shura of their spiritual connection and Excalibur's legacy, helping resolve the stalemate. After Athena's suicide to enter the Underworld, Shura and his companions confronted Pandora, demanding passage to Hades. As their 12-hour limit expired, they disintegrated into stardust. In his final moments, Shura reaffirmed the Excalibur's purpose within Shiryu.
Posthumously, Shura's spirit joined the other gold saints in focusing their cosmos to breach the Wailing Wall during the Hades arc, enabling access to Elysion. Astrologically, Capricorn's association with Saturn (representing restriction and pragmatism) and Mars (symbolizing martial prowess) aligns with Shura's initial rigid loyalty and combat-focused nature. His techniques include the Excalibur slashes, the dual-bladed Double Excalibur (*Episode G*), and the defensive Jumping Stone maneuver.
The film *Legend of Sanctuary* briefly depicted Shura wounding Aiolos in a flashback and participating minimally in the battle against the bronze saints. In the *Soul of Gold* storyline, he sought redemption from Leo Aiolia for attacking Aiolos, haunted by years of guilt over his actions.
