Quick recap
Pallas, a goddess and Athena's sister, awakens and declares war on the Sanctuary with her army of Pallasites. The old Cloths aren't enough, so Koga and his friends get New Cloths. A new boy, Subaru, wears a Steel Cloth and joins the group. The Saints attack Pallasvelda, Pallas's fortress, and find that some of her generals are plotting on their own. Ikki shows up again to fight Aegaeon. Athena faces Pallas in a duel between goddesses, and soon a bigger enemy appears: Saturn, god of time, who had been hiding very close to the group. In the final battle, Koga's Cosmo awakens the Omega power, and he defeats Saturn, closing out the series.
