Season two of Toei's CG-animated Saint Seiya reboot picks up right after the Bronze Saints' first battles, as Seiya and his companions face a new threat aimed at the goddess Saori, Athena reborn in human form. To reach her and stop what's coming, the Saints have to fight their way through the Twelve Houses of the Sanctuary, each one guarded by a Gold Saint far stronger than anything they've faced before. This ONA season adapts the manga's Golden Twelve Houses arc and continues directly from the first season's ending.
