Once, there was a war against giants known as the Zentradi. Humanity, on the brink of extinction, ventured into the vast cosmos, entrusting their future to new frontiers and setting out on a journey. After many years, peace and coexistence with the Zentradi were achieved—thanks to the songs of a single songstress. The "Galactic Fairy" Sheryl Nome, the "Super Dimensional Cinderella" Ranka Lee, and the "S.M.S. Pixie Squad Captain" Klan Klang. Now, these beautiful songstresses and warriors are defiled at the whims of desire, consumed utterly, forced to sing songs of despair and ecstasy. [Translated from dlsite]
