Lua is a candidate for the saintess position, possessing the gift of healing, yet with a cruel twist—she can only heal others by transferring their injuries onto herself. This ability has earned her the mocking title of the "Fallen Saintess." Her best friend Arianne has always stood by her and defended her. When Commander Garrett, someone Lua deeply admires, is gravely wounded in an attack, Lua heals him at a great cost to herself, nearly losing her life in the process. Upon regaining consciousness, she is shocked to find that all the credit for the act has gone to Arianne, revealing Arianne's true nature. Heartbroken and lost, Lua meets the second prince, who offers her a tempting proposition. She then embarks on a new path as an antagonist.
