Description
Mur dell'Ariete, also known as Aries Mu, is the Gold Saint who guards the first temple of the Sanctuary in the anime Saint Seiya: The Hades Chapter - Sanctuary. He was born in Tibet and trained under the previous Aries Saint, Shion, who later became the Grand Pope. Mu became a Gold Saint at a remarkably young age and is recognized as possessing the strongest raw psychic power among all living Gold Saints. After suspecting that his mentor Shion had been assassinated by Gemini Saga, Mu distrusted the corrupt leadership of the Sanctuary and withdrew to the mystical region of Jamir, a place accessible only to those with high psychic or Cosmo abilities. There he lived in seclusion with his young apprentice Kiki, devoting himself to the repair and restoration of damaged Cloths, a skill for which he is uniquely renowned.

Mu’s personality is calm, logical, and scholarly. He is soft-spoken and tranquil, often handling situations with measured rationality rather than emotion. While this demeanor can appear cold, it stems from a disciplined mind rather than malice. He is deeply loyal to Athena and the cause of justice, but he is cautious and does not act impulsively. His judgment is guided by reason and long-term strategy. He is respectful toward the ancient Libra Dohko and shares a close friendship with Taurus Aldebaran, whose loss affects him deeply. He also maintains a respectful rapport with Virgo Shaka, as both share a connection to Buddhist philosophy.

In the Hades Chapter - Sanctuary, Mu plays a pivotal role as one of the first defenders against Hades’s invasion. When the resurrected Specters, including his former master Shion, the traitorous Deathmask, and Aphrodite, arrive at the Aries Temple, Mu initially hesitates out of respect for his teacher but ultimately fights to protect Athena. He uses his Starlight Extinction technique to apparently eliminate Deathmask and Aphrodite, though they later reappear. When confronted by Camus, Shura, and Saga, Mu is immobilized by Shion but manages to sense the tears of blood in their hearts, understanding that they are being forced to act against their will. After Aldebaran’s death, Mu mourns his friend and continues moving through the Sanctuary to coordinate with the other Gold Saints. He also teleports Pegasus Seiya away from danger, demonstrating his strategic concern for the Bronze Saints.

Mu’s notable abilities are centered on his supreme psychic powers, which include telekinesis, telepathy, and teleportation. He can move himself or others across vast distances, even across dimensions, though such feats drain his energy. His defensive technique, Crystal Wall, creates a barrier that repels and reflects attacks. He also uses Crystal Net, a web-like variation to trap enemies. His offensive moves include Starlight Extinction, which engulfs the target in blinding light and either kills them or teleports them to another location, and Stardust Revolution, a powerful barrage of luminous energy that overwhelms opponents. As the only living Saint capable of fully restoring Cloths, Mu uses rare materials such as Gammanium, Orichalcum, and Star Dust Sand, and he requires a portion of the wearer’s blood to perform the repair.

Throughout the Sanctuary arc of Hades, Mu’s role evolves from a cautious observer to an active combatant. He demonstrates unwavering dedication to Athena’s cause, and his intelligence and psychic mastery make him an indispensable ally. His development is marked by a growing willingness to sacrifice for the greater good, setting the stage for his eventual fate in the later parts of the Hades saga. His relationships with Shion and Aldebaran highlight the tension between duty and personal bonds, and his calm, precise nature contrasts with the more passionate Bronze Saints, grounding the story with a steady presence of wisdom and power.
