Shinkyoku Sōkai Polyphonica (神曲奏界ポリフォニカ), also known as simply Polyphonica, is an all-age Japanese visual novel created by Ocelot and first released on the PC on April 28, 2006. An anime adaptation started airing in Japan on April 3, 2007. Another anime adaption aired from April to June 2009, and was a prequel of the events in the first anime.
The first series followed the lives of the employees of the Tsuge Divine Music Players Office, in particular, Tatara Phoron and his contracted spirit Corticarte Apa Lagranges (Corti). Crimson S, on the other hand, sets out to show how Phoron and Corti became partners, with much hi-jinx and shenanigans from evil musicians and school bullies along the way. At first glance it appears as though this is nothing more than a prequel to the first series and, for the most part, this would be a fair assessment. Unfotunately, there are some deviations that occur in Crimson S that openly contradict some of the events from the first anime, one of which is Phoron and Corti’s first meeting with the Yugiri twins (Perserte and Prinesca). The first series very clearly shows their first encounter to be at Tsuge’s offices, however Crimson S has them being school friends.
