Plot

Rin is an energetic girl who lives in a grassy frontier village. Finis spends her days in solitude deep within the royal palace in the bustling capital city. While the girls appear to be opposites, they share a special power that no other person has—the power of song, which can heal wounds, create and control the elements water, fire, earth, and air. Guided by destiny, the two young women each face an arduous journey as the shadow of war looms over the kingdom, tainting their miraculous songs with the blood of innocents. Loved ones meet their deaths as silent screams echo through a stone prison, and Rin and Finis hope that their last song will be one of hope.

Rin is an energetic young brown-haired girl harboring a passion for singing living with her adopted younger brother Al, adopted older sister Mel and grandfather Talgia Hawklay in a reclusive village near a forest. She discovers her ability to sing Spirit Songs, legendary songs that can manipulate the four elements of the world and bring about miracles. Unlike Finis, her songs energize her instead of taking away her lifespan. After Mel and Talgia died, she promised to live her dream of singing with the Court Orchestra in the Capital and save as many lives as she can with her powers. Rin was originally a part of Finis, the last bit of Finis's hope of her feelings for Henry and Song of Healing, who came to existence after Finis purged it from herself to sing the destructive and deathly Song of Mortality. Singing the Song of Healing for Finis to grant her wish to restore the world to its former state ultimately would lead to Rin’s "death" but she follows through regardless. After the duet of the Lost Song is completed, Rin vanishes and emerges with Finis as the verse states that hope (Rin herself) would disappear after the ultimate wish was fulfilled.
