Long ago, harmony across the galaxy was maintained by a sacred star known as the Mother Planet. But that peace was shattered when the Mother mysteriously exploded and vanished without a trace. In the aftermath, the galaxy plunged into chaos and conflict. Yet from the scattered remnants of the Mother Planet, new beings were born—sentient fragments known as the Galverse. Now, these Galverse girls, each imbued with extraordinary powers and an unstoppable gal spirit, rise to confront the evil organization "Space End Society." As they battle across the stars, they begin to uncover the truth behind the galaxy's collapse—and the fate of the Mother Planet itself.

A squid-like creature, known as a Happian, leaves his home planet with the desire to spread happiness across the universe. He lands on Earth, but quickly finds himself in danger of captivity by its inhabitants. Fortunately, he is found by an unsmiling little girl named Shizuka Kuze, who feeds him and names him Takopii. Feeling indebted, Takopii decides to do everything in his power to bring a smile to her face. The task is easier said than done, however. Shizuka is bullied by her classmates, she does not have a father, and her mother is never home—though the gravity of these issues flies over the naive Takopii's head. Even so, Shizuka does have one source of happiness: her dog Chappy. The connection Shizuka and Chappy share only increases Takopii's desire to make the girl smile. While Takopii's attempts to lift Shizuka's spirits lead to unintended consequences, he is determined to take things into his own tentacles, test his understanding of human beings, and achieve his goal of spreading happiness.
