Shinkyoku Soukai Polyphonica

A new client comes to the Office with an interesting proposal. He needs an object retrieved from the bottom of the sea, his late father's brief case, in the hopes that its contents will settle an inheritance dispute with his brother. The problem is that his brother has hired a rival divine song player.

The Yugiri twins reminisce over their father's memento and the first time they met Phoron and Eufinley at the Torvas Divine Song Players Academy.

Suzuna comes to the Office believing that her spirit has breached its contract and is working for another Dantist. Eufinley takes on the assignment of investigating the matter. It is clear that the spirit is visiting a Dantist with whom it formerly had a contract with. It is not immediately clear as to why.
