Two girls with the power to sing reality into being discover that the same songs that heal can destroy. War doesn't care about miracles. The OST doesn't just accompany the story, it IS the story, each track a piece of what these characters can actually do, which means every song hits different when you understand what it costs them to sing it.

Two young women share a rare gift: songs that can heal injuries, summon water and call up the wind. Cheerful Rin lives with her family in a green frontier village and has learned to hide her power. The reserved Finis performs inside the royal palace in the capital, spending her days mostly alone. Rin's peaceful life ends when she uses a healing song on a wounded knight, Henry Leobort, and soldiers who saw her raid her village to seize her. With her inventor brother Al, she sets out for the capital. Finis, meanwhile, has fallen for Henry and must keep it hidden from the greedy Prince Lood, who wants her for himself. She hopes to help people through song, but as war draws near she fears Lood will send her magic to the battlefield. As the kingdom slides toward conflict, the fates of the two singers begin to cross in this twelve-episode fantasy drama built around music.
