Mika dances all alone to the sound of the enemy's song. She's completely unafraid of injury and death. As a powerful healer she is capable of living forever if she so chose to. There is nothing in this world that can harm her and she knows it. That is why she hides herself away from the world; no one will use her again to harm others. When a warrior, Park, finds her he tries to persuade Mika into helping protect his country, the land of Adrina. They've been under attacked and he needs the most powerful group of people to save his soldiers as they become injured in battle. At first Mika is hesitant; there's no way she can go through all the break and bending this war will cause. When Park asks her to accompany him on his journey to find others, she complies. On their journey they will encounter remarkable characters, an unmistakable bond, and plenty of obstacles in which Mika will think she is fighting on her own in a war that's already been won.
