Shoko y Kyoko nacieron bajo un cruel destino que siendo niñas estuvo a punto de costar la vida de una de ellas. Ahora, ya como adolescentes, Kyoko lleva varios años fuera de casa y Shoko no sabe por qué más allá de que está estudiando. La sorpresa llegará cuando en su reencuentro, Kyoko se presente como una Saintia.

Cuando los enemigos atacan de nuevo a Atena, Shoko intenta acudir en su ayuda al igual que Delphinus, pero todavía no está preparada.

Shoko acude al lugar donde está el cuerpo de su hermana esperando para ser el receptáculo de Eris, pero aunque no tiene capacidad para enfrentar a los enemigos, está dispuesta a hacerlo. Es entonces cuando llega alguien dispuesto a detener el problema de una forma más drástica.

Kyoko's Cosmo disappeared in the battle at Eris' temple. Saori's heart wavers as she questions her existence from not being able to save Kyoko in defeating the evil god. However, with Saori inheriting Mitsumasa Kido's will, the Galaxian Wars start without mercy. On the other hand, Shoko who was in the hospital had been depressed from Saori telling her goodbye, and she drops the pendant of Pegasus given to her by her sister. The boy who caught it for her was Pegasus Seiya who was entering the Galaxian Wars.

Mayura and the Saintias work hard to calm the evil spirits while Seiya and the Bronze Saints hurry through the Sanctuary to save Athena. Now, the deadly battle of the twelve temples begin.

After the deadly battle, the Saints of the Sanctuary all swear their loyalty to Saori-Athena. Meanwhile, Eris, who was thought to have been sealed, had fused with her host, Kyoko, and multiplied her powers. Saori rises against Eris to protect Shoko, but receives the curse of the apple. The Gold Saints head to the Temple of Eris along with the Saintias to save Athena and to stop the evil god from scattering the Evil Seeds of war that fill people's hearts with hate. That's where Aiolia witnesses his own brother turning his fists against him.

Can you defeat your sister who has fused with the evil god? With Mu's question, Shoko agonizes over the fate she bears. That's when Orion Rigel, the Ghost of an ex-Silver Saint, stands before Shoko.

Finally, Shoko faces the evil god Eris. As Saori's Cosmo grows weaker, all of the Saintias-Shoko, Mii, Xiaoling, Katya, and Erda-put their hearts together to challenge Eris. The Gold Saints continue to protect the Sanctuary as they find out Eris' plan of crashing the temple into it.
