Aiacos recovers and attacks Ikki with Galactica Illusion. At Giudecca, Hades and Pandora sense Ikki's powerful Cosmos. He asks Pandora to bring him before his throne. Ikki gets up and uses the Phoenix Illusion, with Aiacos seeing his own death in his head. Aiacos is then finally killed by Ikki's Flying Phoenix. Shortly after his victory and before he is able to challenge the two remaining Judges, Ikki is surrounded by a strange light and disappears. Pandora teleports Ikki to Giudecca. He is surprised to see his brother as Hades. Pandora reminds Ikki of when they first met, when he almost lost his life protecting his baby brother. Pandora, holding what looked like the Universe in a mantle, tried approaching the baby Shun, but a powerful Cosmo kept her at bay. Not willing to risk Shun's body, Pandora gives Shun the pendant seen earlier, and takes her leave. In the present, Ikki finally remembers everything. The pendant, which reads "Yours Ever", was from Hades, who chose Shun to be his vessel. Ikki destroys the pendant and knocks Pandora out of the way. He goes to his brother and tries to snap him out of it. Hades pushes Ikki back and reveals his plan, the Grand Eclipse. His plan is to align all the planets in the Solar System, blocking the Sun from the Earth. This eternal eclipse will cause Earth to undergo a new Ice Age, becoming a world of death. Ikki attacks Hades numerous times with a strengthened Cosmo which destroys most of the throne room, but his attacks are easily returned by the God. Suddenly, Hades begins strangling himself. Shun's spirit appears behind Hades and tells Ikki to destroy Hades once and for all.

Seiya still struggles against Valentine, who attacks him again. The Specter tries to retrieve Athena's Cloth, but Seiya keeps him from taking it. Athena's Cosmo awaken Seiya and he stands to fight again. Meanwhile, Saori begs on her knees and asks Hades to stop the Grand Eclipse, but he refuses, yet Saori is willing to give up her life. Hades gives Shaka Pandora's trident, and orders him to kill Athena. But Shaka throws it at Hades, although Saori stops the trident. Hades points the trident at Shaka, but she stands in his way. Seiya and Valentine charge at each other, Seiya killing the Specter with his Meteors of Pegasus. Saori stops the trident, and bleeds. She burns her Cosmos and as the blood touches Hades and hurts him, his hair color is changing back to red and then to green. Hades' soul escapes Shun's body and charges at her. Saori strikes him with the trident, stained with her blood. However, Hades attacks her and both gods disappear. Shiryu and Hyoga kill multiple Specters on their way to the Eighth Prison and sense Athena's Cosmos disappearing. Pandora, Kanon, Rhadamanthys, Minos, Dohko and Seiya also sense Hades and Athena's Cosmos disappearing.

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.

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.

Right before everyone's eyes, Aldebaran, Saga, Deathmask, Aiolos, Shura, Camus and Aphrodite came back to life. Friends and comrades happily reunite, (Aiolos with Aiolia; Camus with Hyoga; Shura with Shiryu; Aldebaran with Seiya; Deathmask and Aphrodite with Mu. Also, Kanon's soul unites with Saga) but the reunion is short lived. Aiolos pulls out an arrow, preparing to fire it at the wall. Aiolia says goodbye and warns the Bronze Saints to leave. Dohko says all 12 Gold Saints will focus their Cosmos to Aiolos' arrow in order to destroy the wall, but it will cause an explosion so intense, that the Gold Saints will lose their lives. He explains that no human can reach the Elysium Fields, but the Bronze Saints can since their Cloths are bathed in Athena's blood. Dohko says that Hades cares a lot about his body and keeps it sealed in Elysium, which is why he possesses a human whenever he revives. Finally, he orders them to destroy Hades' body, which will end the Holy Wars between Athena and Hades, forever. The 12 Gold Saints bid a heartbreaking farewell to the four Bronze Saints. Seiya and his friends, with tears in their eyes, bid farewell to the brave soldiers who taught them so much and escape. Dohko reminds Shiryu that Shunrei prays for him and Shura reminds him of their battle and to remain strong. Camus reminds Hyoga of their battle and assures him he can win. Aphrodite also reminds Shun of their battle and believes he will make a miracle. Minos confronts the Bronze Saints and easily blocks their attacks. The 12 Gold Saints entrust the Earth, Athena and the future to the Bronze Saints as Aiolos fires the arrow, and causes a monstrous explosion, destroying the Wailing Wall. Minos is caught in the blast, seemingly defeated. Seiya and his friends rush back inside, seeing the Gold Saints have opened a path through the wall. But the Gold Saints have died, only the 12 Gold Cloths remained. Their spirits bid farewell to the Bronze Saints, reminding them to stay strong, fight for justice and never lose hope. Having mourned the Gold Saints' deaths, Seiya and his friends head towards the Elysium Fields to hand Athena her Cloth, destroy Hades and stop the Grand Eclipse. Saori is then shown trapped in a giant urn, turning red at the bottom. Ikki also heads towards the Elysium Fields, with Pandora watching him, remembering her childhood.
