Lithos Chrysalis (リトス・クリサリス, Ritosu Kurisarisu) is the daughter of a sculptor who served the shrine before his untimely death.
Sometime prior to the beginning of the manga, her father died due an un-named illness.
Lithos first appears in an evacuated city, observing a giant figure that is rampaging throughout the city.
Later, she encounters Aiolia, who has been sent to eliminate the 'Gigas'. It is revealed that the 'Gigas' is actually a giant stone statue being possessed by the Cosmos of Lithos' father and that he doesn't realize that he has died and has been searching for his beloved daughter.
Aiolia helps her father move on to the afterlife by stating that he will look after Lithos.
