One year after the defeat of Abzu, peace has returned to the world. However, a new threat rises with the advent of Pallas, an old enemy of Athena. Despite knowing that, Seiya can't find the resolve to kill the young Pallas as she is still an innocent child although she is destined to eventually come after Saori's life. Meanwhile, Kouga, training while still recuperating after his battle against Abzu, meets Subaru, a Steel Saint who is eager to challenge him in order to become a God. However, Kouga refuses to fight him and claims that with the world in peace and his cloth destroyed, there is no reason for him to fight anymore. However, a Class-3 Pallasite named Tarvos, one of Pallas' minions armed with a Morning Star as his weapon, attacks the three of them. Watching Tatsumi take the hit in his stead and Subaru quickly being outmatched, Kouga burns his Cosmo, and the Pegasus Cloth is revived into a New Cloth.
