After losing his sight and father while searching for an ancient sword in the waters of Dan-no-ura, where the Heike clan met its end, Tomona turns to playing the biwa to survive. Renamed Tomoichi, he joins a renowned storytelling troupe. A chance encounter with a disfigured individual, known as Inu-Ou, leads to an unexpected friendship. Together, they mesmerize audiences with forgotten tales of the Heike clan, defying societal norms and attracting widespread acclaim. Their unorthodox performances, however, provoke the ire of traditionalist forces, setting the stage for a clash between innovation and entrenched customs.
