After Cure Muse's mission of restoring her father's kind heart was accomplished, Ako and Mephisto decided to return to Major Land together. Suddenly, a howling noise rang through the city, and when it died down, all music was gone. Ako and Mephisto tried to establish contact with Major Land, but could not get a response. Full of worry, Hibiki and the others headed to Major Land, where there was no sign of the former land of overflowing music. The world was desolate without sound, its people devoid of emotion like stone, continuing to play their soundless instruments. The only one left was Ako's friend Suzu, who explained how Aphrodite suddenly changed and took away all music from the land. Ako and Mephisto, unbelieving and determined to find out the truth, headed to the palace where Aphrodite was. Hibiki, Kanade and Ellen decided to chase after Suzu, who had run away after Ako refused to believe her story. While chasing after Suzu, the girls met with 3 men eager to steal the Healing Chest. And as the truth slowly came to light, the Pretty Cure had to face up to the real enemy.

In the distant future, a majority of humans have left the Earth, and the Galactic Alliance of Humanity is founded to guide exploration and ensure the prosperity of mankind. However, a significant threat arises in the form of strange creatures called Hideauze, resulting in an interstellar war to prevent humanity's extinction. Armed with Chamber, an autonomous robot, 16-year-old lieutenant Ledo of the Galactic Alliance joins the battle against the monsters. In an unfortunate turn of events, Ledo loses control during the battle and is cast out to the far reaches of space, crash-landing on a waterlogged Earth. On the blue planet, Gargantia—a large fleet of scavenger ships—comes across Chamber and retrieves it from the ocean, thinking they have salvaged something of value. Mistaking their actions for hostility, Ledo sneaks aboard and takes a young messenger girl named Amy hostage, only to realize that the residents of Gargantia are not as dangerous as he had believed. Faced with uncertainty, and unable to communicate with his comrades in space, Ledo attempts to get his bearings and acclimate to a new lifestyle. But his peaceful days are about to be short-lived, as there is more to this ocean-covered planet than meets the eye.
