It has been 243 years since the previous Holy War between Athena and Hades, God of the Underworld. On a tower that Roshi has been observing, the seal Athena placed ages ago has lost its effect. The spirits of the 108 Specters, Hades' soldiers, are now free. At the Sanctuary, Nachi, Ichi and Shaina notice that graves from the Saints' graveryard have been disturbed, with the bodies coming out from the inside. At the House of Aries, a shadowy figure approaches Mu, who seems familiar to him. He orders Mu to bring him Athena's head in 12 hours. When he refuses, two more figures appear. Two Gold Saints whose lives were lost in the Battle of the 12 Houses, Cancer Deathmask and Pisces Aphrodite. Since they sold their souls to Hades, he offered them new lives, bodies, and Surplices, armors from the Underworld, resembling their Gold Cloths.

The shadowy figure deduce that Mu teleported Seiya instead of destroying him. Mu blocks Deathmask and Aphrodite's paths once more and defeats them with Starlight Extinction. At Lushan's Waterfalls, Roshi tells Shunrei he is leaving and might never come back, telling her to not let Shiryu leave her side and wishing Seiya and the others would live peacefully as normal teenagers after fighting for so long. As Roshi leaves, three shadowy figures approach Shunrei. Deathmask and Aphrodite have been vanquished, but three more figures approach Mu. Shaina orders Nachi and Ichi to set fire to the remaining graves, while Jabu discovers that three more Gold Saints were revived. At Lushan, the figures ask Shunrei for the whereabouts of Shiryu and Roshi, but Shiryu, still blind, comes to her rescue.

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.
