Ep 6. Colliding Souls! Saori vs. Grand Master

In Saint Seiya Saintia Sho season 1 episode 6, titled Colliding Souls! Saori vs. Grand Master, the tension between the saintias and the Sanctuary rises as Saori, the reincarnation of the goddess Athena, faces off against the Grand Master, the ultimate leader of the Sanctuary. The episode opens with the saintias still reeling from the events of the previous episode, in which they failed to protect the Pallasites from the Sanctuary. As they struggle to come to terms with their perceived failure, they receive a sudden message from an unlikely ally: Shoko's elder sister, Kyoko.

Kyoko, who had previously been thought dead, reveals that she has been working undercover within the Sanctuary and has information that could be crucial to the saintias' mission. With her help, they are able to infiltrate the Sanctuary's inner sanctum and confront the Grand Master himself. However, things quickly take a turn for the worse as the Grand Master proves to be a formidable opponent, even for Athena.

As Saori and the Grand Master engage in an intense battle of wills, the other saintias are forced to face off against a group of elite Sanctuary assassins. In the chaos, their true strength and resolve are put to the test as they fight to protect what they believe in. Meanwhile, Kyoko's past and motivations are revealed, shedding light on the complicated history of the Pallasites and the Sanctuary.

As the episode comes to a close, the stakes have never been higher for the saintias. Will they be able to overcome their adversaries and protect Athena, or will the Sanctuary prove to be too powerful a foe? Only time will tell as the battle between these two factions continues to escalate.
