Lithos Chrysalis

is the daughter of a sculptor who served Sanctuary, before his untimely death. She was adopted by Leo Aiolia as a little sister and works at the House of Leo as a servant.

History
Some time before the beginning of Saint Seiya: Episode G, Lithos's father dies due an unnamed illness. She is then seen at an evacuated city, observing a rampaging giant that destroys everything in its path.

She runs into Aiolia, who has been sent to eliminate the giant and reveals to him that the creature is actually a giant stone statue that has been possessed by her late father's spirit. Not realizing that he has died, the giant is single-mindedly driven by the desire to find and protect his beloved daughter. Aiolia helps Lithos's father move on to the afterlife by promising to look after her and adopts her as a sister.

Leter on, in order to help the Titan King Kronos regain his memories after he is freed from Zeus's prison, Dimension Iapetos kidnaps Lithos to lure Aiolia into the Titan's realm. There, she befriends the amnesiac Kronos and starts to convince him that humans do not deserve to be destroyed, as the Titans intended.
