Synopsis
Shinkyoku Soukai Polyphonica follows Phoron Tatara, a Dantist with the unique ability to summon spirits through music.
His spirit partner is the powerful and notorious Corticarte Apa Lagranges, who appears as a young girl but has a fearsome reputation.
Together, they work for the Tsuge Divine Music Player Office, traveling across the land of Polyphonica on Phoron's special motorcycle-organ.
They use Phoron's musical abilities and Corticarte's strength to resolve various crises and help people in need.
Essentially, they are a musical duo who solve problems and rescue those in distress, one melody at a time.
