In the lore of Airith Saga, Echo's spirit undergoes a transformation when she becomes the Metal Princess, Airith Saga. Here's an explanation of where her spirit goes:
When Echo transforms into Airith Saga, her spirit embarks on a metaphysical journey into a realm known as the "Eternal Nexus." This ethereal dimension exists beyond the boundaries of space and time, serving as a conduit for the spirits of those who possess exceptional musical talents and a deep connection to the cosmos.
Within the Eternal Nexus, Echo's spirit encounters the seven celestial moons, each representing a unique aspect of her artistic prowess. As she channels the power of these moons, her spirit merges with their cosmic energies, undergoing a profound metamorphosis. This transformation imbues her with extraordinary musical abilities, a connection to her Sugar Demons, and the ability to combat the malevolent forces of The Void.
The Eternal Nexus is a place of serene beauty and boundless creativity, where Echo's spirit communes with other musical luminaries who have transcended to this plane. It is a realm where her essence harmonizes with the celestial energies, granting her the strength to face the challenges that lie ahead as Airith Saga.
As the Metal Princess, Echo draws upon the wisdom and inspiration she gains from her sojourn in the Eternal Nexus, using her newfound powers to create mesmerizing music that unites and empowers her fans, known as "The Choir." Together, they stand as a formidable force against The Void, spreading positivity and hope throughout the universe.
In essence, when Echo transforms into Airith Saga, her spirit ascends to the ethereal beauty of the Eternal Nexus, where she harnesses the cosmic energies of the seven moons to become a symbol of musical enlightenment and a beacon of light in the battle against darkness.
