Shoko is a student at Ryuusei Private Academy Middle School. Her dear sister, Kyoko, had went to study abroad five years ago and hasn't heard from her since. One day, an unknown entity suddenly attacks Shoko. The ones who attacked her had been the Dryads, underlings of the evil goddess, Eris, who was once sealed by Goddess Athena. When Shoko and Saori Kido awaiting the Galaxian Wars meet, the gears of destiny begin to turn.

The underlings of the evil goddess, Malice Emony and Murder Phonos, plot to take Athena's head to offer it to Eris and raids Saori. Mii stands up against Emony who continues to call Saori an "incomplete god". Shoko's Cosmo flare up during the training with Mayura. Sensing Athena's danger from the Cloth's box, can Shoko ultimately save Saori?.

Shoko succeeded in entering Eris' temple by chasing Phonos who fled battle. As she searches the temple to save her sister, Kyoko, she is informed of a shocking fact by Ate. When Ate's vines catch Shoko off guard and begin to attack, a golden light enwraps her body. To bring back Shoko, Mii heads to Eris' temple and reunites with her where they find Kyoko's ragged body before their eyes.

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. Aiolia and Milo, who face Saga in a deadly battle, plans to destroy the temple, however - A raging destiny encircles the Saintias, Gold Saints, evil god Eris, and Saori Kido. The final battle begins.
