Shinkyoku Soukai Polyphonica: Eternal White  

Shinkyoku Soukai Polyphonica Eternal White, 神曲奏界ポリフォニカエターナル・ホワイト

In Polyphonica, spirits manifest in the world through music played by humans. These spirits survive on this musical energy and coexist with people. Although they don't appear frequently, some powerful ones can materialize in human or animal forms and live alongside humans. Dantists, those who play a unique type of music called "Commandia," are highly respected in this world. They often have contracts with strong spirits. The narrative of Shinkyoku Sōkai Polyphonica Eternal White centers on Snow Drop, a new Dantist who deeply loves her Ojou-sama and her Contracted Spirit, Blanca, also known as the renowned Contra Bass, Eternal White.
