Shion and Dohko's power clashes, but it seems Shion has the upper hand, due to Dohko's current appearance. Feeling this, Shiryu tells Seiya to go ahead while he goes to help his master. Dohko orders Shiryu to leave and attacks Shion with the One Hundred Dragons. Hyoga and Shun arrive at the Sanctuary, but Shaina stands in their way. Dohko's dragons are no match for Shion who counters with his ultimate attack, Stardust Revolution. Shiryu wears his damaged Dragon Cloth and attacks Shion. Shun understands why Saori gave the order, but he realizes they must protect her no matter what. Shaina prepares to battle Hyoga once he starts burning his Cosmo. At the House of Aries, Shion blocks the Rising Dragon, but Dohko gets up and asks Shiryu to leave. However, Shiryu can't leave, knowing his master is fighting alone. Dohko agrees to let him stay, promising to apologize to Athena later. Hyoga prepares to attack, but Shaina turns her back and allows them to move forward. Shion attacks, but the Libra Gold Cloth saves Dohko and Shiryu. Suddenly, Dohko burns his Cosmos, and reveals something amazing. His body starts to crack like a shell, and a younger body emerges from the old one. The young Libra Dohko has returned. He reveals that Athena gave him the gift of Misopethamenos, which allowed him to stay young, meaning, since 243 years passed, for Dohko, it was only 243 days. Dohko tells Shiryu to follow Mu and defeat the Specters that came to the Sanctuary. Dohko dons his Cloth after 243 years and prepares for battle. Shion and Dohko clash with their ultimate techniques, Stardust Revolution and the One Hundred Dragons. Shiryu is sent flying due to the impact. Seiya, Mu, Hyoga, Shun and Shiryu sense both Shion and Dohko's Cosmos have disappeared.

Aiolia, Mu and Milo sacrifice themselves, stalling Rhadamanthys, allowing the Bronze Saints to find the room where Saga and his group is. The Gold Saints are tossed into the Underworld, presumably losing their lives. Saga and the others' 12 hours are up and the Bronze Saints mourns their deaths after receiving some timely advice before disappearing. Hyoga kills Zeros, because he was stomping Camus, with the Aurora Execution. Just as they spot Pandora, who is going to the Underworld, and try to go after her, Rhadamanthys appears and gains the upper hand on the Bronze Saints. Seiya gets up again, struggling to attack Rhadamanthys. As the Specter is about to toss Seiya down to the Underworld, Shiryu, Hyoga and Shun attack at the same time, but he knocks them down again with his Greatest Caution technique. The Bronze Saints struggle to get up, remembering the words of the Gold Saints and fight back. Rhadamanthys attacks again and Seiya faces him once more. With his Comet Punch, Seiya is able to damage his Surplice. Seiya's Cloth turns gold and he and Rhadamanthys fall down into the Underworld. As the sunrise gets closer, Dohko and Shion contemplate the fact that the Bronze Saints are fighting again. Shaka's message was actually a way to reach the Underworld, alive, which is where he and Saori are right now. Shion, confident that the Bronze Saints will awaken the Eighth Sense, based on the miracles they have achieved in the past, says goodbye to his old friend Dohko and disappears. He and Kanon head towards Hades' Castle. Shiryu, Hyoga and Shun burn their Cosmos, hoping to reach the Underworld alive. Seiya heads to the Underworld, hoping to reach Saori.

Shiryu, Hyoga and Shun are about to jump into the hole leading to the Underworld, but Dohko stops them, warning them that only Specters will be able to reach that world alive. He also tells them that they must reach Arayashiki, known as the Eighth Sense. Shaka and Athena had reached this sense by being as close to death as possible, to reach the Underworld alive. Dohko and the Bronze Saints, thanks to their previous battles, awaken the Eighth Sense, and land in the Underworld. Seiya has made it as well, reaching the Eighth Sense beforehand and encounters Shun. Now they must find Saori and give her Cloth to her. Seiya and Shun reach the Acheron River, and see dead people who lived their lives in apathy and aren't allowed to cross the river. A boat comes with a Specter, Acheron Charon, who guides dead people across the river. He begins to fight the Saints, but offers them a ride in exchange for money. Shun offers Charon a golden pendant, something he has had since he was a baby. Even though Charon says it isn't enough, he gives them a ride. At the halfway point, Charon knocks Seiya off the boat where he is being dragged to the bottom by dead people who tried to swim across. Shun saves Seiya and he attacks, breaking through Charon's Rolling Oar defense. The Specter falls into the water, asking for help since only he knows the way to the other side. Shun helps him, but Charon attacks Seiya with Eddying Current Crusher. He then attacks Shun, but looks at his pure eyes, being aware of his pure heart and stops the attack, thinking he might end up in Elysium, a paradise for people chosen by the Gods. Thankful to Shun, Charon returns him his pendant and agrees to take him and Seiya to the other side, on the condition they settle the score. Charon explains the contents of the Underworld, consisting of 8 prisons, 3 valleys, 10 pits, and 4 spheres. Seiya and Charon continue their battle. Since Seiya has seen both of Charon's techniques, he is victorious, killing the Specter with his Meteor of Pegasus. Hyoga, Shiryu, Dohko and Kanon have also made it to the Underworld, but are in different parts of it. Seiya and Shun reach the First Prison, the Palace of Justice.

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.

The Bronze Saints head to the Elysium Fields, but Shiryu stays behind, sensing the presence of Specters. Three of them appear, Alraune Queen, Minotauros Gordon and Basilisk Sylphid. Shiryu fights them all at once, unleashing the force of Excalibur. Seiya, Hyoga and Shun reach the other side of the Wailing Wall, but find an inter-dimensional path of time and space. At the end of the path is a shining light, leading to the Elysium Fields. Minos, having survived the blast, catches up to them, with Hyoga staying behind to fight him. Hyoga makes an ice barrier while Seiya and Shun go forward. Minos breaks the barrier and uses Cosmic Marionation on Hyoga. Seiya is being dragged by the pressure of time and space, but then his Cloth grows wings, due to Athena's blood. He rescues Shun and both head to the Elysium Fields. Hyoga freezes the threads of the Marionation, immobilizing Minos and attacks with Aurora Execution. Minos barely survives and traps Hyoga with a remaining thread, but he is suddenly destroyed due to the dimensional pressure, proving only gods can walk the path. Hyoga and the others were spared because of their Cloths bathed in Athena's blood. Shiryu holds his own against the three Specters, taking their attacks head on and still fighting. He challenges all three to attack him at once and kill them with his master's technique, One Hundred Dragons. With the pressure of the techniques, Shiryu flies all the way to the inter-dimensional path, where Hyoga is waiting for him. Sylphid somehow survived and goes after Shiryu but he is also destroyed by the pressure. With his Cygnus wings, Hyoga takes Shiryu to the Elysium Fields. Meanwhile, Seiya has successfully made it and wakes up in a utopian paradise.
