In Asgard, a land filled with snow in Northern Europe, a woman known as Polaris Hilda, representative of the Norse God Odin, prays to preserve the peace in her land. Suddenly, a mysterious force speaks to her, urging her to destroy the Sanctuary. Hilda refuses, so she is swept away by the force. When she recovers, a strange ring is on her finger, and she calls upon the God Robes of the Asgard God Warriors. Seven warriors are granted these sacred Robes: Siegfried is granted the Dubhe God Robe Robe of the Alpha star, Hägen is granted the Merak God Robe of the Beta star,...

In Asgard, Hyoga is escaping with a young girl named Freya, Hilda's younger sister. Asgard soldiers trap Hyoga and try to convince Freya to come back to her sister, but she refuses, hoping that Athena will save her sister. Hyoga defeats the soldiers. Then, Saori appears before Hyoga and Freya. Seiya, Shun and Kiki arrive, and Freya explains that Hilda is not acting like herself. The worst part is, the world is now in danger. Hilda was praying to stop the Polar ice caps from melting, but since Hilda stopped praying, the ice caps are melting and will flood the Earth. ...

Seiya, Hyoga and Shun rush to find the Valhalla Palace, which is farther away, but the giant God Warrior Thor stands in their way. Shun and Hyoga attack, but are useless against him as he easily breaks free from Hyoga's ice and knocks down Shun with his Cosmo. Seiya decides to distract Thor, allowing Shun and Hyoga to move forward. Seiya stops Thor's Mjolnir Hammer technique with his Meteor of Pegasus, but Thor simply changed their direction towards Shun and Hyoga, knocking them out cold. Seiya, now alone, manages to evade Thor's Mjolnir Hammer, but before he is able ...

Thor strikes, with Seiya falling down an icy cliff, and even then, the attacks against Seiya continue. However, he is rescued by Shiryu, who has come from the Five Ancient Peaks of Lushan and brought information from Roshi. The master reveals that to remove the Nibelung Ring, one must have the legendary sword Balmung. To retrieve the sword, the seven Odin Sapphires, the seven God Warriors' guardian stones, must be gathered after defeating them. Shiryu goes to wake up Hyoga and Shun while Seiya distracts Thor, but Seiya is knocked down again. Saori's Cosmos burns ...

While Saori tries to keep the polar caps from melting, Kiki and Freya stayed behind to look after her. The Bronze Saints head for different paths. While Shiryu looks for his next opponent, Capricorn Shura's spirit reminds him to protect Athena. It is revealed that when Shiryu used his Final Dragon, Shura loaned his Gold Cloth to him and pushed him back to Earth, with his last words telling him to live on and to protect Athena. At the Valhalla Palace, Siegfried tells Hilda he is confident about his strategy to defeat the Bronze Saints. At a frozen waterfall, Shiryu is ...

Shiryu seems to be no match against Fenrir's ruthless attacks. His friends sense he is in danger, but are confident they will make it to the Valhalla Palace. Meanwhile, Hyoga is followed by another God Warrior. Remembering Shura's sacrifice, Shiryu gets up again, and tries to convince Fenrir that Hilda is possessed, needing the Odin Sapphire to save her and to trust him. Fenrir, however, doesn't believe in people and only trusts his wolves. He then tells Shiryu the reason of his mistrust. Years ago, when Fenrir was six years old, he was part of a distinguished family....

Shiryu fights back, stating that he believes in his friends and will fight for his beliefs as both warriors clash again. Fenrir keeps fighting for Hilda's sake and backs Shiryu into a corner. The Rising Dragon is useless to Fenrir and Shiryu has seen through his techniques as well. Shiryu gets an idea and uses the Rising Dragon against the frozen waterfall, causing a massive avalanche, with both him and Fenrir caught up in it. The avalanche ends, and the wolves desperately look for Fenrir while Shiryu emerges from the debris. The wolves find Fenrir, but he has died, ...

Hägen unleashes the mighty technique Universe Freezing against Hyoga, but it is useless against him as he easily breaks free. Hyoga then tells Hägen that he let himself be captured by Asgard soldiers to discover what happened to Hilda. He was even severely beaten by Thor. But Freya came to Hyoga's cell and freed him, hoping that Athena and her Saints would help save her sister and Asgard. Hägen refuses to listen and attacks Hyoga with vicious assaults. Hägen remembers being Freya's closest friend during their childhood and one of Hilda's most loyal warriors. Hyoga ...

Hyoga is confused as to why Hägen can withstand the heat. Hägen received his God Robe in that place and has trained there since childhood, mastering both ice and fire techniques. As Hyoga tried to see through Hägen's technique, he is continuously overpowered and knocked down, but still manage to stand up and asks for the Odin Sapphire. Both attack each other again, but Hyoga falls unconscious. Just as Hägen is about to throw Hyoga into the lava, Freya arrives and tries to tell him about Hilda and the Nibelung Ring. However, Hägen still believes Freya is being ...

After making a grave for Hägen, Hyoga has Kiki take care of Freya and heads for the Valhalla Palace. Hilda, angered that three of her God Warriors have died, is confident she can still win since most of the Bronze Saints are injured. After Seiya falls off a cliff, he remembers how the Gold Saints Aiolia, Milo, Aldebaran, Shaka and Mu gave up a portion of their blood in order to revive their five Bronze Cloths, which explains their new appearances. The Gold Saints made this sacrifice as a sign of gratitude to the Bronze Saints for rescuing Athena. Seiya climbs back up ...

Shun still struggles against Mime's abilities and illusions. He then removes his Cloth and chains. While talking to Mime, Shun realizes he's not fighting for Hilda and also dislikes fighting. Shun awakens the Seventh Sense and uses the Nebula Stream to immobilize Mime. Finally, he unleashes the Nebula Storm in order to defeat him. Unfortunately, Mime survives thanks to his harp. He then envelopes Shun with the strings on his harp, preparing for his final attack, Stringer Requiem. As Mime plays his music preparing to kill Shun, the chains still cannot sense any hatred....

Ikki is able to miraculously dodge Mime's light-speed attack due to his battle against Saga, and also manages to see through his illusion technique. While Ikki is fighting, he senses something in Mime's mind. Ikki tells Mime that he used to hate his destiny and it was because of his friendship with Seiya and the Saints that he found a reason for fighting. Even though Mime gains the upper hand, Ikki cannot sense any hatred within him either. Mime reveals his childhood past. He was trained by his father Folker, a mighty warrior of Asgard, respected by all, who forced ...

Ikki tells Mime that he hates himself for killing his father and should make up for his crime by saving Asgard from Hilda's wrath. Mime then remembers how Folker trained him, because he knew that he would be chosen as a God Warrior to protect Asgard. As Mime attacks, Ikki is able to counter, but both seem evenly matched. Suddenly, Mime uses his Stringer Requiem and Ikki is trapped while Mime plays his music, preparing to kill him. Shun tries to stop him, but Ikki tells him to pull back, saying he will defeat Mime. Ikki burns his Cosmos to the Seventh Sense and frees ...

Alberich leaves to defeat the Saints. As the Saints get closer to the Valhalla Palace, Shiryu finally recovers from the fall. Alberich has always hated Hilda for not appreciating his intelligence, and he secretly plans to recover the Odin Sapphires for himself. Just then, a Saint attacks him and tries to escape. The Saint is revealed to be Eagle Marin. Alberich reveals to Marin that they are in the area of his "collection" of victims, skeletal warriors trapped in an amethyst casing. Marin knocks down Alberich, but he cheats by spraying acid in her face. Seiya senses ...

Seiya remembers how Marin was a good influence on him, but he knows he has to save Athena and Asgard, so he decides to defeat Alberich. However, Alberich reveals his Sword of Flame, which came with his Megrez God Robe and tries to slash Seiya with it, while at the same time, tricking Seiya about Marin.

Hyoga senses Seiya's Cosmo disappearing and rushes to find him. It is revealed that ...

Hyoga saves himself and strikes with all of his techniques, but they seem to be ineffective against Alberich. Meanwhile, Shiryu is able to climb up the ice cavern and return to the battlefield, thanks to his master's advice. Alberich leads Hyoga deeper into the forest where he unveils a secret technique handed down from his ancestors, Nature Unity, where the spirits of the forest come alive and attack the enemy. Shiryu senses Hyoga is in danger and tries to find him. As Hyoga struggles to get up and fight, Alberich uses the Amethyst Shield, but is saved by Shiryu in ...

As Shiryu struggles with the Nature Unity, Roshi speaks to him, telling him to remain motionless and become one with nature. The spirits then release Shiryu. Unfortunately, since Shiryu starts moving again after being provoked by Alberich, the spirits attack him again, so he becomes one with nature again. However, Alberich does whatever he can to distract Shiryu's concentration. Alberich remembers that his family was left with the task of protecting the Odin representative on Earth, but since Hilda uncovered the God Robes, the Odin Sapphires were uncovered as well. He...

Hilda is very confident is Syd's victory, and while Shun enters the palace, Syd appears before him, remembering their last encounter. Seiya and Hyoga arrive, but just as Seiya challenges Syd again, Shun has him and Hyoga go forward while he fights the God Warrior by himself, promising to catch up later. While both of them run past Syd, a mysterious figure sees them. Shun attacks with his Nebula Chain, but is useless against Syd's cold air. Outside, Shaina arrives and finds Marin. She then tells Shaina about how Aldebaran was defeated. He survived, but revealed to ...

As Shun gets up, Syd reveals Seiya and Hyoga will die soon due to the cold air in the palace. Shun struggles to defeat Syd in order to rescue his friends, but his chains are ineffective.

Shun also remembers the Gold Saints' ...

Ikki arrives after his battle with Mime, determined not to abandon his brother. Bud, angered at the fraternal bond between Shun and Ikki, begins to attack, saying that compassion is useless. Ikki miraculously blocks Bud's light speed attack before they clash, whereupon Bud's helmet is knocked off, and his face is exactly like Syd's. Bud reveals that Syd is his younger twin brother. Ikki confronts him about not helping his brother, and Bud responds that if Syd dies, he will become the true God Warrior of Zeta, and no longer be a shadow. Ikki attacks, but Bud easily ...

It seems Ikki is no match for Bud. Shun and Ikki try to attack together, but are both knocked down by Bud. Ikki then uses his Phoenix Illusion against Bud. In his mind, Bud defeats Syd, but for some reason, he can't give him the death blow. Ikki confronts Bud about trying to help out Syd during his battle with Shun, even though he claimed he wanted Syd dead. Ikki and Bud clash again, with Ikki coming out on top after awakening his Seventh Sense. Suddenly, Syd sneaks up on Ikki and holds him so that Bud can defeat him. Even though Bud is concerned, Syd tells him he's ...

Kiki tries to stop Freya from going to Saori's side, who is getting weaker by the minute. She realizes that even though Siegfried is the last God Warrior, Siegfried is reincarnated from a warrior with the same name, who became immortal after defeating a dragon and bathing in its blood. Shun and Ikki take Hyoga with them further into the palace. Seiya reaches the Odin statue, but Dubhe Siegfried stands in his way, not willing to show any mercy.

Shiryu faces Siegfried on his own, despite not wearing his Dragon Cloth. No matter what technique Shiryu uses, Siegfried is unscathed, making him wonder if he's really immortal, just like the legend. Back at the caps, Saori can't hold on anymore. Shiryu is struck by the Odin Sword technique and thinks about using the Final Dragon, like he did on Shura. He holds on to Siegfried and prepares the forbidden technique. Just then, Shura's spirit talks to Shiryu and tells him not to do it, otherwise not only will he not protect Athena, the Odin Sapphire would be destroyed as...

Both warriors use their techniques, but Seiya is overpowered and falls to the ground, yet he was able to land several hits on Siegfried's heart. Saori, Shiryu and his friends deposit their Cosmo into Seiya, making Siegfried doubt is Hilda is right, or if Athena is true justice. Hilda suddenly arrives and attempts to finish off Seiya, but Siegfried stops her to confirm his doubts. They attack again, with Seiya's Meteors pushing back Siegfried's Dragon Bravest Blizzard and attacking his heart. Seiya has finally won and goes to retrieve the Sapphire. But a man, playing a...

With her evil power, Hilda tries to kill Seiya. Shiryu, Hyoga, Shun and Ikki struggle to help their friend. Saori's Cosmos won't last much longer. Seiya fights back, but can't kill Hilda, otherwise Asgard and the world would be lost. Hilda attacks and Seiya falls down a cliff. As Seiya is about to give up, Saga's spirit calls out to him, reminding him of their battle and how he awakened the Seventh Sense to defeat him and save Athena. Saga also reminds Seiya that he will win as long as he has hope, entrusting him with Athena. Seiya climbs back up and heads for Odin's ...

Seiya is victorious and the Nibelung Ring is finally destroyed. The Odin Robe removes itself from Seiya's body, completing its mission. However, Hilda is down, and bleeding.
