Set seven years before the events of the original Saint Seiya manga, the story of Episode G revolves around Athena's Saints, a group of humans with superhuman powers who are devoted to the Goddess of War Athena. Their duty is to protect the world from evil. The protagonist is Leo Aiolia, who is mistrusted by his fellow Saints because of the seemingly traitorous actions of his brother Sagittarius Aiolos in the past. In turn, Aiolia holds a grudge against the Saints as a whole, and against the elite order of the Gold Saints in particular. While Aiolia is sent on mission after mission to prove his loyalty, a modern-day Titanomachy begins as the Titans, ancient gods with a desire for revenge on the Olympian gods, attack the earth.
