Individual Decisions! The Goddess and Saintias
Shoko cannot hide the shock knowing Kyoko was taken away instead of her as the evil god’s host. As Shoko finds out the special position of Athena’s handmaidens as well as bodyguards that only women can fill, she decides to become a Saintia herself from her desire to become stronger in order to rescue her sister. Saori requests the Silver Saint, Pavo Mayura, for Shoko’s training, however… On the other hand, Milo and Aiolia at the Sanctuary were sensing the evil Goddess Eris’ suspicious moves.

Aired 17/12/2018EP 2 - Individual Decisions! The Goddess and Saintias

Saint Seiya Saintia Sho
The anime is set immediately after the main storyline's Sanctuary arc after the defeat of Gemini Saga from Masami Kurumada's original Saint Seiya manga, but before the Posieidon arc. However, whereas the original manga followed a boy named Seiya and other Saints who fight to protect the goddess Athena, the new series follows a female "Saintia" named Shō who fights evil deities to protect Athena.
