Shinkyoku Sōkai Polyphonica

After the game, the Polyphonica series expanded into a light novel series. The stories are loosely connected in a shared universe setting. The novels are published by GA Bunko, a division of Softbank Creative. Some of the series are identified with colors. The Black series happens in the same timeline as the Crimson series, which follows the main characters of the game. The White series appears to take place in the distant past.
