Fairy gone (TV Series)

In a world where the fairies inhabit animals (endowing them with special powers), humans begin to transplant the organs of the possessed animals to their soldiers, to use these fairies as weapons during the war. These individuals would be called "Fairy Soldiers". Years after the end of the war, Maria is a new recruit from the organization "Dorothea", which is dedicated to investigate crimes and incidents related to the fairies and humans who now control them.
