Based on the light novel 'crimson' Polyphonica series by Sakaki Ichirou (Scrapped Princess, Straight Jacket) which in turn is based on a visual novel by the same writer.
Human beings rely on the miracles of fairies, while the fairies that have materialized in this world survive on the music played by humans. The fairies' powers are directed by Dantists, who play special music and are widely respected.
Most fairies don't usually appear, but some have enough power to materialize in the shapes of human beings or animals to spend their time living in peace together with mankind.
This is a story of the budding love between Conticarte and a new Dantist, Phoron, who reside in Polyphonica, a continent where people and fairies live together in harmony.
