Athena (アテナ; Atena), spelled in Greek as Ἀθηνᾶ and Ἀσάνα, is the goddess of love and war.  She is sent to Earth every 200 years, when evil takes over Earth. Her mission during every one of her incarnations is to restore peace and bring hope, destroy the agent of evil and protect Earth. To do so, she has been assisted since the age of myth by an army of 88 youths of great strength and courage, whose fists rend the skies and whose kicks split the earth, who don radiant holy armor called Cloths, and who are known as the Saints of Athena.

Athena is said to be by birthright the goddess of battle, but she does not believe in conquest and only fought defensive wars. She hates weapons, and thus only allows her Saints to battle using their bodies and armors. The only Saint allowed to wield weapons is the Libra Gold Saint, and it is only with her permission that the Saints are allowed to brandish the weapons kept by the Libra Saint.

She has opposed the ambitions of antagonist deities since the age of myth in Greece, earning herself the rejection of the other Olympian gods. She has especially had a long-standing conflict with the god of the Underworld, Hades.
