Summary of Saint Seiya before the Hades chapter.

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.

At Hades' castle, Wyvern Rhadamanthys, one of the three judges of the Underworld, begs Pandora, a beautiful girl and Hades' representative, to give him permission to go to the Sanctuary, but she refuses, and says the revived Gold Saints will handle the mission of killing Athena. Mu heads for the House of Taurus to find Aldebaran. Shun awakens after he keeps having dreams of a girl who resembles Pandora. Sensing something is wrong, he heads towards the Sanctuary. Tatsumi, under Saori's orders, tries to keep Shun from leaving, but to no avail. Mu finds Aldebaran, but the Taurus Saint has died, and only his Gold Cloth and a small trace of his Cosmos remain. The one responsible emerges from the shadows, a Specter, Deep Niobe, who was sent by Rhadamanthys. Deathmask and Aphrodite invade Hades' Castle, hoping to see the god, but Rhadamanthys sends them to the Land of Death.
