Seven years before the events of the original Saint Seiya, Leo Aiolia still lives under suspicion inside the Sanctuary: his older brother Aiolos was branded a traitor and killed, and the other Gold Saints have not forgotten it. When the Titan gods are loosed from Tartarus and move against Zeus and Athena's Sanctuary, Aiolia has to fight alongside the same Gold Saints who distrust him, with Hyperion, the first Titan set free, among the first to come for them. This spinoff manga, supervised by original creator Masami Kurumada and drawn by Megumu Okada, gives Aiolia's Sanctuary years their own story outside the main series.
