Since the initialization of the logical organization, Haizakura has been unable to sing. I want to be on stage with her once again. The puppets of Kuronekotei, hoping for a ray of hope, decide to cross the sea. They crossed the sea to Lobelia, a country that was once their enemy. In order to meet Cyanas, a first-generation autonomous doll with the same performance as Ouka, they decided to put on a show on the stage of the peace ceremony. Can Haizakura make her singing voice sound once again?
