Eternal Sonata

Story
As famous classical composer Frederic Chopin lies on his deathbed his spirit explores a world that he believes to be entirely his dream. In this world, he meets a girl named Polka who is the same age that his younger sister, Emilia, was when she died. Polka, too, suffers from a terminal illness, one that grants her the power of magic. She sets off on a journey to the city of Forte to try to convince the officials there to halt the production of mineral powder, a healing powder that has greatly hampered the sales of her local village's floral powder. Frederic joins her on the journey and the two are soon joined by other concerned citizens, who soon discover a conspiracy much greater than they imagined. As they move forward, Frederic's certainty that the world around him is only a dream wavers, and he begins to search for a way to save the young girl who so reminds of Emilia.
