Saint Seiya: Hades

In the Five Peaks, Dohko has a vision in which Athena is beheaded by Hades. At that moment he realizes that the day has finally come when Hades and his 108 Specters will return to Earth. In the Sanctuary, Mū finds that several Knights have revived by the power of Hades in exchange for bringing the head of Athena. Among them, Death Mask of Cancer and Aphrodite of Pisces are the first to fight, along with a mysterious third Knight that is capable of destroying the incredible defense of Mū.

Aphrodite and Death Mask see how Seiya's body has disappeared, but the hooded specter doubts that Mū has killed Seiya. Mu becomes enraged with Death Mask and Aphrodite, and then makes them disappear with his Starlight Extinction.

In Hades Castle, Germany, Wyvern's Radamanthys Specter meets his Pandora Owner asking permission to go to attack the Sanctuary, but she refuses. Disobeying it, send more than 10 Specters to fight the 12 Houses.

Saga tells Shura and Camus to continue since he will take care of the Knight of Gemini. Saga recognizes the opponent as his brother Kanon, and seeing that he is controlling the Gemini Armor from a distance, launches an attack that reaches the Patriarch's Chamber. Milo of Scorpio meets Gemini Kanon in this place and orders him to leave. Before the refusal of the Kanon, Milo begins to attack him with his Scarlet Needle.

Saga, Shura and Camus find that the interior of the House of Cancer has become the entrance to the world of the dead, but they realize that it is an illusion.

Shion and Dohko begin to fight, but Dohko is overcome in power due to his old age and the youth of Shion granted by Hades. Shiryū arrives only to see how his master is defeated and wants to intervene, but he can not do anything against the power of Shion.

Mū arrives at the remains of the Cancer House and is immobilized by a large group of Specters led by Giganto de Cíclope and Myu de Papillon. When Mū was going to be eliminated, he is saved by Seiya who reappears but is beaten by Giganto, when they were going to kill him, Myu stops his comrades and orders them to continue

Seiya falls exhausted and upon awakening meets Shiryū, Hyōga and Shun. Meanwhile, the Specters led by Giganto arrive at Leo's House, meeting Aiolia. Five Specters are launched against Aiolia but it kills them with a single blow, and the others doubt what to do until Worm Raimi arrives and says it will be responsible for eliminating Aiolia.

The five Gold Saints burn their Cosmos and toss the weapons into the Wailing Wall, but are ineffective and come back to them. Shaina gathers with Jabu and the other Bronze Saints. Marin and Kiki arrive as well, deducing that chaos is occurring around the world, due to the Grand Eclipse. Seiya takes one of the weapons and attempt to destroy the Wailing Wall, like he did with the Main Breadwinner in Poseidon's Sanctuary, risking his life. Out of nowhere, a light appears. At the Sanctuary, lights coming from the Houses of Taurus, Cancer, Sagittarius, Capricorn, Aquarius and Pisces head towards the Underworld. Hyoga and Shiryu have made it through the last Prison and notice the lights headed toward Giudecca. The lights are the souls of the deceased Gold Saints and their Gold Cloths. All Gold Cloths have gathered in the Underworld, resonating with one another. Kanon removes his Gemini Cloth, sending it to Giudecca, and fights Rhadamanthys again, however, he seems to be at a disadvantage. Kanon takes a hold of Rhadamanthys and as they rise farther into the sky, he uses a final Galaxian Explosion, destroying them both. He then bids farewell to Athena and his brother, Saga. Hyoga and Shiryu make it to the Wailing Wall and see all 12 Gold Cloths in one place. Suddenly, the empty Gold Cloths come apart and begin to take shape.

Giganto becomes enraged when he learns that Saga and the others killed three Specters to pose as them in front of Shaka, although Saga does not care and warns him to leave if he does not want to be killed.

With words of encouragement from Marin, Seiya gets up and heads towards Giudecca. He finds Shun back to normal and both go deeper into Hades' Temple. Back on Earth, Jabu, Ichi and Nachi see the eclipse, but are confident Seiya and his friends will return. At the orphanage, Seiya's friend Miho and her students also see the eclipse. Seiya and Shun reach the Wailing Wall, which covers the path to the Elysium Fields. Shaka is there and tries to break through, but it is impossible, for only gods can go through it. Saori and Hades are on the other side of the wall. Shaka deduces that Hades' real body is located in the Elysium Fields. Just then, Athena's Cosmos burns throughout the Underworld. Some Specters reach Cocytos and find Valentine's corpse. Just then, Athena's Cosmos revives Aiolia, Mu and Milo. They quickly kill the Specters and as they head for Giudecca, they realize Ikki is gone. Shaka stops Seiya from wasting his energy, trying to break the wall and remembers that the only thing that can destroy the wall is sunlight. Shaka then expands his Cosmo in order to try to make sunlight. Dohko stops him from trying to sacrifice himself. Aiolia, Mu and Milo arrive as well. Mu shows Shaka that most of the beads from the rosary have changed, meaning most of the Specters have died. When all seems lost, Dohko knows how to bring sunlight to the Underworld. He reminds his fellow Gold Saints that their constellations and Cloths surround the Sun in the Ecliptic and have stored sunlight within them. Dohko then distributes his Libra weapons among the Gold Saints in order to destroy the Wailing Wall. Meanwhile, Marin has brought the mysterious girl with her towards the Sanctuary.
