iolia (ア イ オ リ ア, Aioria) was the Golden Saint of Leo in the 20th century until the War against Hades in 1990. Aiolia is a character from the manga and anime Saint Seiya known as The Knights of the Zodiac and protagonist of the Spin-offs Episode G and Soul of Gold. He is the youngest brother of Aiolos, despite his somewhat explosive personality, he has a pure heart that quickly identifies justice, which is why he was one of the first saints to recognize Athena's authority. As his brother Aiolos was branded as a traitor, Aiolia felt an obligation to clear the family name by swearing fidelity to the Pope and even voluntarily participating in the extermination of the rebellious Bronze Saints.

During the battle with the wraiths he faced the enemy army and brought down many of them, serving as the central attack power in the Sanctuary. He died at the Wailing Wall to help the Bronze Saints cross the Elysion. It appears briefly as Einherjer during the events of Soul of Gold.
