In a world where fairies inhabit animals, granting them mystical powers, a bygone era saw these creatures used as weapons of war. By extracting and implanting fairy-infused organs into humans, these 'Fairy Soldiers' wielded formidable alter egos in battle. With the war long over, these soldiers grapple with newfound purpose, dispersing into government ranks, criminal syndicates, or even terrorist cells. Enter Mariya, a fresh face in 'Dorothea,' an organization tasked with investigating and quelling fairy-related crimes in the wake of a tumultuous political climate. As old wounds resurface and vendettas reignite, postwar turmoil fuels acts of terrorism, painting a grim backdrop for Fairy Soldiers seeking their own brand of justice.
