Episode list

There is pouring rain and floods in all parts of the globe. Tatsumi, Jabu and the other Saints are aware of the panic around the world and wonder what is happening. In Asgard, Seiya and Shun return to Hilda and Freya, with no trace of Saori's whereabouts, but they do believe Poseidon has taken her to the underwater Sanctuary. Saori awakens and encounters Poseidon, but she recognizes him as Julian Solo. She first met him during his 16th birthday party. Julian Solo's family is one of the wealthiest sea merchants in the world and he is the heir. When he met Saori, he proposed marriage to her, but she respectfully declined. Julian was chosen as Poseidon's reincarnation and vessel. Poseidon tells her that the rain will continue for 30 days, and the water will remain for 150 days, killing all of humanity, but spared Saori, since he is still in love with her. He offer Saori the chance to rule beside him, but once again she rejects him. Saori is willing to sacrifice herself, and hopes her Saints will arrive to crush Poseidon's ambition. Back in Asgard, Hilda and Freya discover ancient texts that reveal a path to Poseidon's Sanctuary. The path is a giant whirlpool, and Seiya and Shun are sucked in. They arrive at the underwater Sanctuary, and there's no water since the water is held up above them. Suddenly, Mermaid Thetis, a Mariner working for Poseidon appears. Seiya and Shun chase after her, trying to see if she knows where Saori is. Thetis tries to trap them using her Coral Trap to encase them in coral, but Seiya destroys it. Just then, the Mariner General, Sea Dragon, appears and easily defeats the Saints with one strike.

Seiya and Shun recover and defeat the Mariners who have arrived. Meanwhile, Poseidon takes Saori to a place where she will give humanity a chance to live, by sacrificing her life. He explains that the underwater Sanctuary has Mammoth Pillars that hold up the seven seas: the North Pacific, South Pacific, North Atlantic, South Atlantic, Indian, Arctic, and Antarctic Oceans. The Mammoth Pillar holding up the sea in its entirety is the Main breadwinner. If it is destroyed, the underwater Sanctuary will be no more. The water that is raining down on the Earth, now falls upon Saori while locked inside the Main Breadwinner, flooding the room inside, drowning her, giving humanity a chance. Also, the seven Mammoth Pillars are being protected by the Mariner Generals, Poseidon's high ranking warriors said to be as powerful as the Gold Saints. Sea Dragon leaves and Thetis tells Seiya and Shun about Saori and the Mammoth Pillars. Saori will die when the room inside the Main Breadwinner is filled with water. The only way to destroy the Main Breadwinner is to destroy the other seven Mammoth Pillars and defeating the seven Mariner Generals. With their mission clear, Seiya and Shun head for the Pacific Oceans. At Lushan, Kiki takes Shiryu back to Asgard to reach Poseidon's Sanctuary. Even though Shunrei is sad about Shiryu leaving, Roshi explains that it is his and the Saints' destiny to save the world. After defeating more Mariners, Seiya reaches the North Pacific Mammoth Pillar. He launches a Comet of Pegasus to destroy the Pillar, but it's blocked by the Mariner General, Seahorse Baian. Hyoga returns to Asgard and dives into the whirlpool towards Poseidon's Sanctuary. Seiya's Meteor of Pegasus is blocked by an invisible wall created by Baian. He is then sent flying by Baian's God Breath.

Seiya was attacked twice by Baian's God Breath, and is still able to stand. Baian uses his most powerful attack, Rising Billows, which sends Seiya all the way to the surface of the Pacific Ocean. Shiryu and Kiki arrive in Asgard and dive into the whirlpool. Seiya was able to return to the battlefield, determined to win. As he attacks with his Meteors again, Seiya is able to break through Baian's defensive wall. Shun arrives at the South Pacific Mammoth Pillar and sees a mysterious woman, but she transforms into a demon. It attacks, but Shun is able to defend himself with the Roling Defense. Being taunted by the guardian of the Pillar, Shun is confronted by the Mariner General, Scylla Io. Back at the North Pacific Pillar, Seiya's Pegasus Cloth started to shine like a Gold Cloth for a moment. Seiya explains that it was the Gold Saints' blood, which revived the Bronze Cloth, that turned it gold. Grateful for what the Gold Saints gave him, Seiya attacks again. Meanwhile, Thetis stands in Shiryu's way, but Kiki distracts her with his telekinesis while Shiryu leaves, unfortunately he is no match for the mermaid. Baian is confused as to why Seiya's attacks reached him, but Seiya explains that he was able to attack him because Lizard Misty, the first Silver Saint he ever fought, used a similar defensive wall and saw through it. Baian's Seahorse Scales were cracked due to Seiya's Meteors. Baian attacks again, but his techniques are now useless against him. Seiya burns his Cosmo to the Seventh Sense and his Pegasus Cloth turns gold again. With a mighty Comet of Pegasus, Seiya finally kills Baian. Shiryu and Hyoga arrive and Seiya explains the situation to them. They then head off to different pillars while Seiya stays behind to destroy the North Pacific Mammoth Pillar.

With his dying breath, Baian tells Seiya he will never be able to destroy the pillar. Seiya's Comet and Meteor of Pegasus are useless and fail to even make a scratch. Meanwhile, Kiki is saved by Ophiucius Shaina who brought the Libra Gold Cloth with her, under Roshi's orders. Seiya plans on destroying the pillar using his own body, but Kiki stops him and brings the Gold Cloth to him. Meanwhile, Shaina stayed behind to fight Thetis. The Golden Shield flies to Seiya's hands, and he uses it to finally destroy the North Pacific Mammoth Pillar with a mighty throw. As the pillar is destroyed, the Sanctuary shakes and it appears as though the sea is coming down. The Saints and Thetis sense the pillar is destroyed as well. Hyoga and Shiryu split up to go to different pillars. Seiya tells Kiki to find Shun and give him the Libra Cloth. Meanwhile, back at the South Pacific Ocean, Shun remembers the legend of Scylla, which turns into six horrible beasts (eagle, wolf, queen bee, serpent, bat and bear) and when a ship sailed near its lair, six sailors would meet their doom. Io starts his assault with his first attack, Eagle Clutch and breaks Shun's defense. Then, he uses Wolf's Fang, Queen Bee's Stinger, and Serpent Strangler, which severely injure Shun. Next is Vampire Inhale, making Shun lose a lot of blood. Finally, Io unleashes the strongest attack, Grizzly Slap. However, he didn't attack full force in order for Shun to choose the attack that will kill him. As Io uses Queen's Bee Stinger, Shun counters with his chain turning into a Spider Net, allowing him to destroy the queen bee.

Io attacks with Eagle Clutch, but Shun counters with a Casting Net and destroys the eagle. Shun doesn't want to fight, but Io continues with Serpent Strangler. Shun finishes it off with Spiral Duct. Poseidon talks to Saori about the night they met. Julian went to Cape Sounion and found Poseidon's Trident. Thetis appeared and told him Poseidon reincarnated in him and took him to Poseidon's Sanctuary to rule. Poseidon's Scales covered Julian and has ruled the oceans since that day, willing to destroy humanity for contaminating the planet the gods bestowed upon them. However, Saori still has faith in her Saints. Io attacks with Vampire Inhale, but Shun counters with Boomerang Shot. Io continues with his Wolf's Fang, so Shun destroys it with Wild Trap. Finally, Io uses Grizzly Slap, but Shun finishes it with Great Capture, breaking the Scylla Scale. Shun now focuses on destroying the South Pacific Mammoth Pillar, but it doesn't work. Io gets free and attacks with his Big Tornado. Shiryu reaches the Indian Ocean Mammoth Pillar and faces Chrysaor Krishna and his Golden Lance. Shun recovers and keeps trying to destroy the pillar, much to Io's shock. As Io prepares to kill Shun, he awakens his Seventh Sense, splits the Big Tornado and captures Io again. This time, however, Shun's Andromeda Cloth turns gold.

Shun realizes the Gold Saints' blood caused the miracle, but Io assures the pillar will never be destroyed, not even the Gold Saints can do it. Shun decides to sacrifice his life to try to destroy the pillar. While Seiya and Hyoga try to find the next pillars, Kiki gets to Shun in time and Libra's Twin Rod flies to Shun's hand. Shun destroys the Mammoth Pillar, but Io sacrifices himself to save it, but to no avail. The South Pacific Mammoth Pillar is destroyed. As Io dies, he tells Shun that he must not have compassion for the enemy, or he will lose his life as well. Shiryu continues his battle with Chrysaor Krishna at the Indian Ocean Mammoth Pillar, struggling to dodge the Golden Lance. Shiryu challenges Krishna's Lance with his own Dragon Shield. Unfortunately, the Lance goes through the shield and Shiryu's body. Shiryu keeps the Lance in his body in an attempt to break it, but it doesn't work. When hope seems lost, Capricorn Shura's spirit talks to Shiryu and reveals something when he saved his life. Shura gave power to Shiryu's right arm, allowing him to use the legendary sword, Excalibur. Shiryu gets up and faces Krishna again. Both weapons clash, but the shield stops the lance. Shiryu's shield and Dragon Cloth turn gold and Shiryu tries to use Excalibur, but it doesn't work. Krishna believes Shiryu depends too much on his Cloth, so he removes it, risking his life to awaken Excalibur. Finally, Shiryu corners Krishna and cuts the Golden Lance with Excalibur, along with the Chrysaor Scales. Shiryu asks Krishna to stand down, but he suddenly levitates in the air, unleashing a more powerful Cosmo.

Krishna's Cosmo is keeping Shiryu from reaching the pillar. Not even the Rising Dragon can break through it. Krishna explains that his Cosmo, known as Chakra, is formed by seven vital points. Unless Shiryu destroys those points, the barrier won't be broken. Krishna then uses his Maha Roshini, which leaves Shiryu blind. Shiryu burns his Cosmo to the Seventh Sense and sees the seven vital points. He then uses Excalibur to destroy the points, along with Krishna. Hyoga reaches the Antarctic Ocean Mammoth Pillar, but surprisingly, Aquarius Camus is waiting for him. Hyoga attacks him, knowing full well Camus died in the Battle of the 12 Houses. Camus blocks the attack, trying to prove he is who he is. He then uses Aurora Execution and Hyoga finally believes his master is alive. Kiki arrives at the Indian Ocean Mammoth Pillar. Meanwhile, Seiya also arrives at the Antarctic Pillar, and Marin is there, telling him to come back with him, which he finds strange, since she doesn't express her emotions. Marin reveals she is Seiya's sister, Seika and removes her mask to reveal the truth. She hugs him and Seiya hugs back, overjoyed to finally find his sister, but a sinister shadow appears. Shiryu uses the Libra Sword to destroy the Indian Ocean Pillar. Shun arrives at the Antarctic Pillar, and finds Seiya and Hyoga defeated, with one blow. Suddenly Ikki appears behind him and attacks him.

Shun counters Ikki and wonders why he's attacking him. Ikki suddenly transforms and reveals his true identity, the Mariner General, Lymnades Caça. His ability is to read his enemies' minds and transform into someone they care about in order to kill them. Camus and Seika were also Caça's disguises and defeated Hyoga and Seiya with one blow after deceiving them. Shun attacks Caça for hurting his friends and deceiving their hearts. Caça is captured by the Nebula Chain, but he then transforms into Ikki again, since he knows Shun won't attack him. His theory is proven correct as Shun stops his chains from attacking. Caça changes back and strikes Shun with his Salamander Shock, but senses a powerful Cosmos heading towards him. Meanwhile, Shiryu tells Kiki to continue with the Libra Cloth. As Caça prepares to finish Shun, the powerful Cosmos strikes him, revealing to come from the real Phoenix Ikki. Caça is struck by the Phoenix Illusion and shows Ikki turning into Caça, and him refusing to fight himself. Taking revenge for his friends and brother, Ikki unleashes multiple attacks on Caça. After blocking the Salamander Shock, Ikki launches his Flying Phoenix and takes out Caça. The General then transforms into Shun, hoping to defeat Ikki. Not falling for the deception, Ikki strikes Caça in the heart, dealing him the death blow. Before dying however, he read Ikki's mind and encounters his memory of Ikki's lover, Esmeralda. She then kills Ikki, but is happy to be with her forever. However, this is what Caça would have done, if he found out about Esmeralda earlier. Kiki makes it to the Antarctic Pillar. Ikki stops the bleeding from his friends' wounds and uses the Libra Spear to destroy the Antarctic Ocean Mammoth Pillar. Ikki remembers about how strong love can make a person. He then decides to head for Poseidon's Temple, and leaves his friends behind. He also tells Kiki that if they live or die, is up to the strength of their Cosmo.

Hyoga comes to, tells Ikki he was weak because of his emotions and tells him to continue. Hyoga must control his emotions and be strong during battle, like Camus taught him. He then goes to the Arctic Ocean Mammoth Pillar. Ikki heads to Poseidon's Temple, hoping his friends will remain strong and focus on saving Athena. Hyoga arrives at the pillar and senses a familiar cold air. A Mariner General greets him, and he is revealed to be Issac, Hyoga's training partner when he trained with the Crystal Saint. Now the Mariner General Kraken Issac, he attacks Hyoga, leaving him confused because Issac used to fight for justice and wonders why he has changed. As children, Issac and Hyoga were close friends and grew strong together as the years went by under the Crystal Saint's training. Issac's dream was to become a powerful Saint and fight for justice to protect the Earth. He thought Hyoga's goal was the same. In the present, Hyoga noticed Issac's left eye is nothing but a scar now. Hyoga, sorry for Issac's pain, allows him to destroy one of his eyes as payment. Issac, however, only hurt his eyelid. He then reminds Hyoga of the Kraken legend. The Kraken used to devour ships in one fell swoop, but only attacked people with evil intentions. Issac wanted to have the Kraken's cruelty to defeat evil and fight for peace. One day, Issac found out the real reason why Hyoga wanted to be a Saint, to be able to see his mother in the sunken ship. Angered and disappointed, Issac attacks Hyoga, but at the same time, shows him how to break the ice caps. He also warned Hyoga that if he swims to the bottom, a strong current would trap him, and he would never be seen again. Hyoga finally broke the ice cap, and swims, but is caught in the current. Issac swims down to rescue his friend, who is unconscious. Suddenly, the current traps both of them. Issac's eye was wounded by a stalactite and tries to break a hole in the ice cap to save Hyoga. He succeeds in saving Hyoga, but Issac is dragged across the ocean, leading him to Poseidon's Sanctuary. Issac found out overtime that Hyoga became the Cygnus Bronze Saint, fought against the Sanctuary and killed his masters, Crystal Saint and Aquarius Camus. That's when Issac decided to become a Mariner General. He then attacks his former friend with his Aurora Borealis.

Shun recovers and tells Kiki to find Hyoga while he goes to the next pillar. Hyoga gets up and tries to tell Issac he's wrong, but Issac insults his former masters, that they weren't strong enough to protect the world. He then attacks Hyoga again, knocking him out. Just then, Kiki arrives, and Issac attacks him to take the Libra Cloth and stop the pillars' destruction. Kiki refuses to let the box go while Issac stomps him mercilessly. Kiki is risking himself, just like his friends are, so he can be a Saint one day. Hyoga gets up and lets Kiki rest until Issac is defeated. Hyoga burns his Cosmos to the Seventh Sense and attacks Issac with Diamond Dust. As Issac recovers, he sees Crystal Saint's and Camus' images behind Hyoga, giving him power. Issac attacks again, but Hyoga blocks it, with the Cygnus Cloth turning gold. He tries to convince Issac again to stop what he's doing. In Athena's Sanctuary, Mu and Aiolia sense what is happening. Aiolia wants to help the Bronze Saints, but Mu stops him because of Roshi's orders to remain in the Sanctuary. Issac prepares one more Aurora Borealis, but Hyoga counters with the Aurora Execution, defeating Issac. He is proud that Hyoga finally set aside his feelings. Hyoga uses the Golden Libra Tonfa to destroy the Arctic Ocean Mammoth Pillar. Before dying, Issac warns Hyoga about the man who started this horrible battle. Meanwhile, Ikki continues toward Poseidon's Temple. However, Sea Dragon suddenly stands in his way.

Sea Dragon approaches Ikki, but he has sensed this Cosmos before. He then attacks Ikki with a Galaxian Explosion, destroying his helmet. Ikki demands Sea Dragon to reveal who he is. He removes his helmet, and he reveals himself to be Gemini Saga's twin brother, Gemini Kanon, who is pure evil. Kanon sends Ikki to another dimension, using his Golden Triangle, which resembles the Bermuda Triangle. He then claims he will rule both the Earth and the sea. Seiya recovers, sensing Saori's weakened Cosmos. Shaina is still fighting Thetis and is able to defeat her with her Thunder Claw. As she leaves, Thetis warns her about fighting Poseidon, who is now a god. Shaina arrives at the Temple, remembering Juilan Solo is a rich merchant and never had any training. But he exposes a powerful Cosmo, just as strong as Athena's. Shaina attacks, but Poseidon immobilizes and defeats her. Seiya senses Shaina's Cosmos and heads to the Temple. Shiryu recovers and heads for the Temple as well. Kanon claims the Generals dying are according to his plan, but he encounters Sorrento, who has survived the battle against Siegfried in Asgard. As they talk, Sorrento doubts if Poseidon really started this battle and demands to know Kanon's identity and if he revived Poseidon. They then sense a powerful Cosmos and return to their pillars. Shun arrives at the South Atlantic Mammoth Pillar and is shocked to see Sorrento. Back in his battle with Siegfried, Sorrento got loose and escaped his grasp, meaning Siegfried's sacrifice was in vain. Shun is attacked by Sorrento's Dead End Symphony, but is saved when they hear Athena singing from the Main Breadwinner.

Saori's singing is heard throughout the underwater Sanctuary. Seiya arrives at the Temple and sees Shaina unconscious. He then encounters Poseidon and finds out that the Main Breadwinner is almost full of water. Seiya attacks, but his attacks come back to him. Poseidon then destroys the Pegasus Cloth and is about to finish off Seiya, but Shiryu arrives in time to protect him. At the Sanctuary, Milo, Shaka, and Aldebaran gather around Mu and Aiolia, with Milo wanting to help the Bronze Saints. Shiryu attacks Poseidon, but to no avail. Hyoga also arrives, saying if they die, they'll do it together. Poseidon strikes all three Saints, destroying the Dragon and Cygnus Cloths in the process. Saori sings again, still alive and struggling to save the Earth. Seiya gets up again, ready to fight. Mu stops Aiolia from trying to leave again, and as they decide how to act, a Cosmo emerges from the House of Sagittarius and heads towards Poseidon's Sanctuary. Aiolos' spirit sent the Sagittarius Gold Cloth, covering Seiya. Meanwhile, Shun struggles against Sorrento, but can't stop the Dead End Symphony. Suddenly, Shun burns his Cosmo and unleashes the Nebula Stream, stopping Sorrento's movements. Shun pleads Sorrento to surrender, saying that he isn't an evil person, especially since he can play a beautiful melody and possesses a noble spirit. Sorrento is about to play his Dead End Climax, but is defeated by Shun's Seventh Sense-empowered Nebula Storm.

Kanon reveal's his evil plot, while Seya dresses in golden armor, fights against Poseidon.

Seiya fires the arrow, but Poseidon controls it, firing it at Seiya's heart. Miraculously, he survives, thanks to the Gold Cloth. Seiya fires again, and Poseidon controls the arrow, but Shaina protects Seiya, and the arrow hits her back. She tells Seiya he is their last hope and that he must not die. At the Sanctuary, a beam of light shoots from the House of Aquarius, heading for Poseidon's temple. Shaina extracts the arrow from her back and hands it to Seiya, saying she will protect him, no matter what, and to fire as many times as necessary. Poseidon controls the arrow again, but Seiya shields Shaina instead. Shiryu instead takes the hit, protecting them both. Hyoga gets up, and both him and Shiryu decide to be Seiya's shields. Shun arrives as well, telling him to keep firing. Only this time, Shiryu and the others will deposit their Cosmo in the arrow. Seiya fires the arrow one last time, hoping it doesn't return this time. Unable to control the arrow, Poseidon is struck by it, knocking his crown off his head, and not only does he start bleeding, but his powerful Cosmo disappears. Seiya and his friends run past him, heading for the Main Breadwinner. Unfortunately, Poseidon fully awakens, unleashing a powerful Cosmos. Back at the North Atlantic Mammoth Pillar, Ikki and Kanon sense Poseidon waking up. Sorrento and Kiki arrive, handing Ikki the Golden Libra Shield, much to Kanon's surprise. Sorrento, knowing Kanon started the battle, lets Ikki destroy the final pillar. Meanwhile, Poseidon fully awakens from his slumber before he attacks Seiya and his friends. Hyoga gets up to protect Seiya, and then, Camus' spirit sends Hyoga the Aquarius Gold Cloth to cover him. He then uses Aurora Execution to try to stop Poseidon's attack. Just as the attack is about to fail, Shiryu blocks it with the Libra Shield and wears the Libra Cloth. Now, Seiya, Hyoga and Shiryu, clad in Gold Cloths, are ready for a final showdown with Poseidon.

Seiya, Hyoga and Shiryu combine their techniques and Cosmo, knocking down Poseidon. Shiryu tries to destroy the Main Breadwinner with the Golden Shield, but it flies back to him, with the pillar unscathed. Meanwhile, Ikki is mercilessly attacked by Kanon, angry that his ambitions are crushed. Sorrento tries to kill Kanon with his melody, but Ikki asks to talk to Kanon, about the one thing used to seal Poseidon's soul: Athena's urn. Seiya and his friends are unable to destroy the pillar with Libra's weapons. Seiya asks his friends to launch his body with their techniques in order to destroy the pillar that way. Shun gets up, preparing to fight. Ikki reveals to Kanon that the Cosmo that saved his life many times in Cape Sounion, belonged to Athena. Finding it hard to believe, since Athena was a baby at the time, Kanon reveals the location of Athena's urn, inside the Main Breadwinner. Ikki leaves for the temple, saying Kanon is not worth fighting. Sorrento, sensing Athena's compassion for humanity, takes his leave, also saying Kanon isn't worth the effort. Poseidon awakens again, but Ikki holds him long enough for Seiya to destroy the pillar and recover Athena's urn. Shiryu and Hyoga launch their Rising Dragon and Aurora Thunder Attack, sending Seiya flying towards the pillar. Poseidon gets rid of Ikki and attacks him, Shun, Shiryu and Hyoga. The four Saints burn their Cosmos, covering Seiya and he is able to make a miracle occur. The Main Breadwinner falls apart and it is finally destroyed. Seiya emerges from the rubble, with Saori in his arms. The ocean comes down hard on Poseidon's Sanctuary, starting to flood it. Saori awakens, with her urn, telling Poseidon to surrender. Poseidon throws his trident to her, but Seiya protects her. Poseidon launches multiple attacks at Saori, but her love for her Saints and humanity cause Seiya and his friends to burn their Cosmos, protecting her and surpassing Poseidon's strength. Then, the God of the Sea's soul is dragged to the urn and sealed once again. With Poseidon's Cosmo extinguished, Athena and her Saints have won the battle. Kiki and Shaina reunite with their friends. Saori then teleports them back to the surface. The floods and rains have seized. Tatsumi, Jabu, Ban, Ichi, Nachi, Geki, Hilda, Freya, Aiolia, Milo, Shaka, Aldebaran, Mu, Marin, Shunrei, and Roshi look up at the sun filled sky, happy that the world is saved. Julian lies unconscious on the surface with Thetis, now a mermaid, swimming away. Seiya, Shiryu, Hyoga, Shun, Ikki, Kiki and Shaina are gathered with Saori. She swears that when evil threatens the Earth and no matter what difficulties they face, she and her Saints will continue to protect and love the world they live in.
