Aquarius Dégel is the Aquarius Gold Saint in Lost Canvas. He is known in Sanctuary as the "wisest among Athena's Saints." He is the only person, besides the Great Pope, who can read and interpret the stars. Apart from this he appears to be very calm and polite. He has his own library and is the only saint who wears glasses.

His first appearance was questioning Sysyphus about the Great Pope. He already knew Sage was dead and the one who had invaded Hades Cathedral wasn't him but his brother, Hakurei, who had dressed in the Pope's clothes.
