Regina Lilia begins as Princess of Ayodoya. Her marriage to Prince Ithaca of Cosmoralia elevates them to King Astralta III and Queen of the Cosmoralian Empire, ruling the planet Astria within the Andromeda Galaxy. Their honeymoon is shattered by an invasion from hostile mechanical beings of another world. These machines assimilate King Astralta III and his ministers, simultaneously terraforming Astria into a mechanical wasteland.

Amidst the invasion, Lilia gives birth to twins, an event regarded as an ill omen in Astrian culture. To ensure their safety, she separates the infants. She keeps one child with her while entrusting the other to Iru, a warrior woman charged with raising that twin. Both infants possess crucial paranormal abilities vital for humanity's survival. Lilia escapes the invaded capital with her surviving son, Prince Jimsa.

Unbeknownst to Astria's populace, exiles from the machines' homeworld, Murat, had selectively bred the royal bloodlines for generations. Prince Jimsa, the culmination of this breeding program, carries the destiny of leading the resistance against the mechanical invaders. Lilia's journey transforms from royalty to protector and refugee, centered entirely on safeguarding Jimsa during the planetary collapse. Her role focuses on ensuring the survival of this prophesied leader against the machine threat.
