As Subaru's time is taken away by the Chrono Destruction, Koga, Yuna, Souma, Ryuhou, Haruto, and Eden still have to face the immense power of Hyperion as well as awaken their greater Omega Cosmo.

The Bronze Saints investigate what they believe to be the final resting place of Shiryu, Kiki, and Fudou, who sacrificed themselves to defeat Hyperion, but they discover that while the Tenchi Destruction Slash has been destroyed, Hyperion has survived with barely a scratch. Koga and his friends must use their new Omega Cloths to take down Hyperion for good. During the battle, Subaru's great and powerful Cosmo once again surfaces to everyone's surprise, along with the proclamation that he is a god. However, after seemingly defeating Hyperion, a strange voice talks to ...

Fudo, Kiki, and Shiryu face off against Hyperion, allowing Athena, Seiya, and Harbinger to move forward. Hyperion's Destruction Tector and Tenchi Destruction Slash holy sword prove too powerful for the three Gold Saints' attacks on their own. In a final show of strength, they combine their Cosmo into a single forbidden attack: Athena Exclamation. The Saints and Pallasites throughout Pallasvelda react to the outpouring of Cosmo, and as the Tenchi Destruction Slash is destroyed, the three Saints' Cosmo vanishes.

The young Bronze Saints face off against Gallia on their own, allowing the Gold Saints and Athena to move forward towards Pallas. Although Gallia's Photontector and Bushin Photon Sword seem impervious to harm, Subaru once more calls on the mysterious powerful cosmo to break through Gallia's offensive and actually damage the sword, convincing the others to call upon their own cosmo, transforming their New Cloths into the more powerful Omega Cloths, and together the six Bronze Saints defeat Gallia.

After dealing with Paradox, Gallia turns her attention to Athena and the Gold Saints, easily deflecting all their attacks until she reveals her Photontector. Meanwhile, the other three groups figure out the meaning of their endless running, figuring out that someone has put them into an endless corridor. As Seiya's attacks are easily deflected, and Gallia is about to kill him, Pallas informs her to stand back, with Gallia mocking Pallas for receiving no love in spite of being the Goddess of Love. However, Integra and Paradox combine their Cosmo, and destroy Europa's ...

Athena, Seiya, Kiki, Fudo, and Harbinger are attacked by their former Gemini Gold Saint ally turned Secondary Pallasite Paradox. Integra, the new Gemini Saint and Paradox's twin sister, arrives to protect Athena and settle their score. Once defeated, Paradox is forgiven by Saori and reforms, just to be later fatally wounded by the Primary Pallasite Gallia.

After mourning the death of Ikki, Shiryu and Ryuhou have to face off against the Secondary Pallasite Rhea. In the occasion, the Libra Saint takes the opportunity to evaluate how far his son had improved his cosmo.

Ikki fights Aegaeon while Koga, Souma, Yuna, and Shun keep moving onward. During the battle, Ikki and Aegaeon sustain grievous wounds. Meanwhile, the Gold Saints discuss Harbinger's loyalty to Athena since she gave the Athena Cloth to him for safekeeping, telling the Gold Saint that Athena trusts him. At the same time, Titan tries to calm down Pallas as she snaps after a Quaternary Pallasite informs her of Ikki fighting Aegaeon. At the end of the battle, Ikki sacrifices himself to completely defeat Aegaeon and all his fellow Bronze and Gold Saints grieve over his ...

While Eden questions Subaru who he really is, Koga, Souma, Yuna, and Shun encounter the Primary Pallasite Aegaeon who wants to test the Bronze Saints' powers himself. After telling the Saints about how Ikki put his life on the line to crack Aegaeon's sword, Shun has a hard time fighting him until Koga, Souma, and Yuna keep fighting the Pallasite, defending Shun. Burning his Cosmo to the maximum, Koga manages to give Aegaeon a crack to his sword, before Ikki arrives to save the Bronze Saints, taking over the battle.

Tokisada, the former Aquarius Gold Saint who was supposed to be defeated by Haruto at the End of Time, appears before him as a Secondary Pallasite at the second path, donning a Chronotector that enhances his time-control abilities. Haruto, Eden and Subaru have a hard time against him until Hyoga appears to battle him in their place.

Koga, Yuna, and Souma advance through the first path while Shun stays behind to deal with the enemy reinforcements. However, the Secondary Pallasite Surtr blocks their path enveloped in a defensive barrier that seems impenetrable, until Shun catches up with them and realizes the secret behind the enemy's trick.

Once inside the castle, Saori and the Saints are informed by Europa that only one of the four separate paths ahead of them lead to Pallas, and flees soon after, thus they decide to split up. Meanwhile, the Heavenly Kings conspire together not only against Athena, but against Pallas as well.

At last Koga arrives at the front of Pallas' castle, which is sealed by the "Gate of Time", a massive door reinforced with Titan's powers. Koga attempts to break through the gate by himself but his own life is put in danger instead, until Athena and her Saints arrive to lend a hand.

As Koga and his friends approach Pallas' fortress, Mira appears before them again, but Ikki arrives in the nick of time to protect them. After the Pallasite flees, Ikki reveals to the other Bronze Saints that Pallas is not their greatest enemy, but an even greater foe who is manipulating the whole conflict from the shadows.

As Saori and her escorts advance through the city overcoming all opposition, Ryuhou is separated from his fellow Bronze Saints by Paradox, who returns as a Secondary Pallasite for a rematch. Paradox's sister Integra appears to assist him as the new Gemini Gold Saint, while the last of the legendary saints, Phoenix Ikki, prepares himself to join the battle as well.

Koga and his friends keep traveling in order to find Kiki and fix their Cloths, as only Eden and Subaru can clear a path for the others. They rendezvous with Shaina and Aries Kiki who repairs their Cloths while explaining to each of them what they must focus on the most while fighting. However, Dione appears, and while the legendary Steel Saints Shou, Daichi and Ushio buy some time fending of the Pallasites with the other Saints, Kiki soon arrives to deal with the Secondary Pallasite himself, before Koga and his friends, with reinforced and fixed Cloths, head off ...

Raki arrives at the city surrounding Pallasvelda to assist the others with a delivery of Cloth-restoring Stardust Sand but is attacked by the Pallasite Halimede, armed with a new triple rod. Koga and Subaru appear to protect her, but while Koga's cloth is too damaged, Subaru's suddenly stops moving out of grief for all the Saints who died wearing it. Eventually, he manages to help Equuleus overcome its sorrow and he defeats Halimede with a Pleiades Tempest. Meanwhile, Saori awakens and retrieves the Cloth of Athena to join the battle as well, accompanied by Kiki, Fudo...

Koga's party departs to the palace through the secret passage shown by Celeris. However, worried about him, Subaru returns to assist the Equuleus Saint, and can do little to stop him from sacrificing himself to defeat Hati. Before passing away, Celeris entrusts the damaged Equuleus Clothstone to Subaru, and upon rejoining his fellow Bronze Saints, Subaru unlocks its true power to protect them, becoming a Bronze Saint as well.

On their way to the palace, Koga and his friends meet Celeris, who fights to protect the refugees with the Equuleus Cloth, despite taking heed of the dreaded curse that befalls whoever dons it. They also meet Selene, a young girl who takes care of all the humans who hide underground who has not been frozen in time, and Eden, with something to protect, has to fight Thebe once again, while Subaru and Celeris encounter Hati and have a short battle with him.

The second day of battles begin, and Koga, Ryuhou, Haruto, and Subaru take a chance to make a beeline for the Palace until they are intercepted by Mira, a Pallasite of unknown rank who fights without donning his Chronotector. Despite seemingly at a disadvantage, Mira easily overpowers the party with his speed and his Alchemy Glove's mysterious power to destroy Saint Cloths just by touching them, until Haruto realizes his trick and comes up with a way to fight back, but Mira is barely scathed by the counter. Just as he is about to don his Chronotector, he is ...

To increase his power for his rematch against Yuna and Souma, Methone uses a dreadful item given to him by Europa to kill his sister Ymir and drain her Cosmo, and the two Bronze Saints must combine their strengths against the empowered Pallasite, as they reminisce upon the day they first met.

The Bronze Saints rescue civilians who were unaffected by Pallas' curse when Koga has an encounter with a young girl, unaware that she is none other than Pallas herself who has sneaked out of her castle. Meanwhile, Saori's body grows weaker due to her Cosmo being drained as Shiryu, Hyoga, and Shun approach the battlefield.

Eden wanders through the city drawn by a strange cosmo when he meets the Secondary Pallasite Europa and is saved by Seiya. Inspired by the Gold Saint to look for a reason to fight, Eden pursues Europa who was sent in a mission to kill Koga, but has a hard time fighting the enemy until Subaru unleashes an impressive power that was dormant within him.

As the battle intensifies, Souma and Subaru fall back to assist the other Steel Saints in time to rescue only two of them, Kerry and Emma. Soon after, they are attacked by Loge and forced to retreat once Souma is injured. Surrounded by the enemy forces, Souma and the Steel Saints must work together to break Loge's siege and fight back.

Once the saints infiltrate the city, Seiya draws the attention of the enemy allowing Koga and the others to push forward. However, Tarvos appears to challenge Koga to a decisive battle and Ryuhou stays behind to assist him.

Now knowing where Pallas is located, Seiya decides to lead an attack on her stronghold with the intention to kill her. On the way to meet him there, Koga and his friends are ambushed by the Tertiary Pallasite Cyllene and Haruto stays behind to confront him. Subaru decides to assist him ignoring his friends' warning and the two find later that they must fight not only Cyllene but also his twin brother Greip.

As the Saints mourn Genbu's death, Hati appears to resume the assault on the Palaestra until Seiya and Athena appear to drive the enemies away. Having finally decided to confront her sister, Saori takes advantage of the curse placed on her to find out where Pallas is hiding.

Aegir fails to defeat Genbu by himself and the Primary Pallasite Hyperion lends his own sword to assist him. Overwhelmed by the massive Cosmo flowing from the sword, the Gold Saint decides to forfeit his own life in an attempt to destroy it.

Koga and Subaru return to the Palaestra which is full of refugees from the villages attacked by the Pallasites and rendezvous with their friends. Genbu approaches the Bronze Saints and, noticing how much their cloths are damaged, reprimands them for relying too much on them instead of their own abilities. When a large enemy force led by the secondary Pallasite Aegir surrounds the Palaestra, Genbu decides to face it head on by himself, while taking the opportunity to share with Koga and the others what he has learned from his teacher, the previous Libra Saint.

The Steel Saints training facility is stormed by the Pallasites led by Hati. Koga and Subaru arrive soon after and they learn that the residents had previously evacuated with former Bronze Saints Ban and Nachi. While investigating, Koga learns about Subaru's origins from his fellow Steel Saint Erna, and it is revealed that among the Steel Saints, Subaru has the strongest Cosmo, and that one day he may find his own Guardian Constelation and become a proper Saint.

Ryuhou, Souma, and Yuna arrive to a village whose survivors of the Pallasite Halimede's attack are under Shun's protection. Among them is Ray, a child whose brother was also frozen by Halimede and blames Shun for it. Halimede instructs Ray to steal the Andromeda Cloth Stone from Shun with the promise of having his brother return to normal, but when the enemy intends to kill both, Shun brings the power of his cloth to the next level.

With orders to kill Koga, Eden attacks him mercilessly until Thebe decides to intervene and the Orion Saint reveals his true intentions as well as his new Orion Cloth.

With Yuna, Souma, and Ryuhou leaving ahead to the Sanctuary, Koga and Subaru look for Haruto in Japan and find, much to their surprise, that he is now a singer in a rock band. Haruto rejects Koga's pleas to return, claiming that to him, his music is now more important than being a Saint. However, during a concert, Haruto watches Koga and Subaru being attacked by some Pallasites, and to protect his friends and his fans, he dons his brand new Wolf Cloth to join the battle.

Unaware of the advent of the Pallasites, Ryuhou believes that there is no reason to fight anymore and wants to return the Dragon Cloth to his father Shiryu, whose senses were restored, and live peacefully with his family. Meanwhile, Koga and the others learn that a Pallasite is after Ryuhou and rush to assist him, but when Ryuhou finds himself struggling to protect his mother Shunrei from the enemy, his renewed determination awakens his true power as the Dragon Saint and the new Dragon Cloth.

Souma, Koga, and Subaru travel to meet Kiki and Raki in order to have Souma's cloth fixed. Yuna arrives there first, but upon having her cloth restored, she finds herself unable to use it and Kiki claims that it is due to her indecision that is wavering her Cosmo. However, when Raki is attacked by two Tertiary Pallasites, Yuna finally gains the resolve to awaken her new Aquila Cloth and fight once more as the Aquila Saint with the help of Souma in his new Lionet Cloth.
