Saint Seiya: Soul of Gold

Shortly after the destruction of the Wall of Grief, Aiolia is suddenly revived in a snowy land, remembering everything that happened as the Gold Saints sacrificed themselves. Recovering in a prison, he meets Lyfia who informs him that he is in Asgard. A maid serving Hilda, Lyfia is rebelling against the rule of Andreas Lise who has become the new representative after Hilda who has fallen under an illness. Lyfia informs him that Andreas is manipulating the people of Asgard and that Hilda entrusted her to stop Andreas. At first refusing to aid Lyfia due to his own battle against Hades along his companions, Aiolia returns to aid Lyfia as the God Warrior Frodi ambush her. Donning his Leo Cloth, Aiolia duels the God Warrior Gullinbursti Frodi armed with the Sieg Schwert which easily deflects Aiolia's attack. Standing up, he notices a strange mark on his body, which Frodi points out that its a mark belonging to deceased warriors known as Einherjar according to Asgardian legends. Aiolia is unable to rival him due to Yggdrasil increasing the God Warrior's power. Seeming defeated, Aiolia hears Aiolos' voice which encourage him to find out why the Gold Saints have revived and in Asgard. Burning his Cosmo to the maximum, Aiolia's Cloth changes form and becomes far more powerful. Once more clashing with Frodi, Aiolia is able to repel the God Warrior's sword before falling unconcsious as his Cloth returns to normal. As Frodi is being carried by some Asgardian soldiers, he notices a slight change in Lyfia's appearance and attitude as she cradles Aiolia. Meanwhile, Mu appears in another part of Asgard and hides from another God Warrior with an evil grin.

Leaving Aiolia to rest after his battle, Lyfia ventures out to find water or food, eventually falling unconcsious in the snow. As she recovers in an empty village, she meets a young boy who gives her something to drink. Shortly after, Mu arrives and informs her that he arrived a few days ago in the village which seemed like everyone had disappeared. Discussing a God Warrior with a dragon-shaped God Robe known as Nidhogg Fafner, Mu asks Lyfia to remain in the village and recover while he dealt with Fafner. Mu ambushes the God Warrior and is easily defeated by his whip before being taken for experimenting by Fafner who binds him to the roots of Yggdrasil. Realizing that Yggdrasil is the source of evil, Mu easily breaks free from the roots and retaliates against Fafner before regrouping with Aiolia and Lyfia, with Fafner escaping. Meanwhile, at an arena, Aldebaran witness Dohko fighting several Asgardian soldiers for sport. As they rendezvous at a bar, the Gold Saints discuss their revival in Asgard and that someone is playing with their lives. Before they have time for further talk, the God Warrior Tanngrisnir Heracles confronts them and challenge them. Leaving him to Aldebaran due to his previous loss during the last battle between Athena's Saints and Asgard, Dohko watches from the tribune as Aldebaran dons his Taurus Cloth. As Heracles attacks Aldebaran, the Gold Saint does not make a move which infuriates the God Warrior. Launching an attack at the civilians instead, Aldebaran moves in the way and deflects the attack. Remembering that he would usually leave the thinking part to his other comrades, Aldebaran burns his Cosmo and regrows his broken horn much to Dohko's surprise, overpowering Heracles for a brief moment before he retreats. During their battles, both Mu and Aldebaran are affected by the same Einherjar mark as Aioria prievously gained during his battle against Frodi. Finally, they all decide to journey to Yggdrasil and destroy it. In another part of Asgard, Milo tortures an Asgardian soldier for information about the God Warriors. He is surprised as the soldier mentions the sight of a Gold Saint.

Aiolia and Lyfia head towards the village of Asgard while splitting up with Mu. Arriving in the village, they encounter Deathmask who prievously encountered Aphrodite and later hanging out at a bar. Pleading with the Cancer Gold Saint, Lyfia is simply rejected as Deathmask is satisfied with his new life, accepting it as a bonus for their sacrifice in the Underworld, showing no worries for Athena, Seiya and the Bronze Saints they sacrificed their lives for. Seemingly challenging Deathmask, Aiolia simply leaves with Lyfia, deciding to find a place to rest for the upcoming night. Meanwhile, Milo travels further through the lands of Asgard, meeting Camus who suddenly attacks him. Shortly after, Milo is confronted by the God Warrior Eikþyrnir Surt. Facing an attack from the God Warrior as well as Camus, Milo is sent falling down the river where he eventually meets with Shaka inside a cave. Refusing to quietly sit by and observe what happens, Milo ventures to find the God Warriors' hidden base, confronting Camus once again. Facing his former friend in a vicious battle, they are seemingly equal in powers until God Warrior Grani Sigmund arrives to finish of Milo. However, Surt intervines and blasts the Gold Saint with his flames. At that momemt, a mysterious figure emerge from the flames surrounding Milo: the Gemini Gold Saint, Saga!

Saga arrives to assist Milo against Camus, Surt and Sigmund who are all astonished at seeing the strongest Gold Saint. Pulverizing the base with his Galaxian Explosion, the two God Warriors and Camus are unharmed due to Yggdrasil protecting them. As they gather their techniques, Saga transports himself and Milo away with the Another Dimension. They later discuss Yggdrasil, before Milo press onward determined to destroy Yggdrasil. At the same time, Aiolia and Lyfia discuss the God Warriors and Andreas as they are unable to sleep. Lyfia reveals each of the God Warriors and who they are. Meanwhile, Deathmask starts noticing lesser villagers around at the bar or in the village, wondering what's going on. As he later stares at his Cloth, Aphrodite arrives informing him that Aiolia left early. Travelling to the market, Deathmask is shocked to see Helena's flower shop not having opened yet, asking the old man what's happened. Rushing to her house to search for her, he instead meet her brothers and sister who tell the Gold Saint she has been taken to a hospital for treatment. As he remembers something the owner of the bar told him earlier, Deathmask rush to this hospital. At the hospital, God Warrior Fafner, who has been doing research to create something special for Andreas, is confronted by Aphrodite who is succesful in exctracting information on how to break the barrier of Yggdrasil before being confronted by Andreas himself. Rushing out with Helena, Aphrodite urges Deathmask to run away as he arrives and grabs Helena, shortly before the Pisces is impaled and captured. Deathmask, furious at Andreas for his actions, swears to kill him even without his Cloth. Just then, his Cancer Gold Cloth once more wraps itself around Deathmask who engage the representative in unequal combat. Lamenting that he wished to help Helena but was unable to do anything, he burns his Cloth and briefly overpowers Andreas as his Cloth changes form, causing Andreas to retreat for the time. As Deathmask cradles Helena, he is horrified and laments as she dies. Finally, Mu reaches the man he had mentioned to Aiolia earlier, revealing it to be Shaka as he asks the Gold Saint about the hidden power in their Cloths: the God Cloth
