Suzuna thinks Kochino, her spirit, has left her and made contract with another Dantist. She goes to Tsuge Divine Music Player Office and asks the group to investigate. It turned out that Kochino made a contract with a Dantist a year before she made a contract with Suzuna. The former Dantist was in a band and when Kochino was there, they were popular, but the former Dantist was so involved in their popularity that his soul got warped and divine songs are a player's soul. So she broke the contract.
