Song is magic—it can change the world, even fate.
Seven years ago, a great catastrophe devastated human civilization.
In this broken world, the once cutting-edge academic city of Kamitsubaki has achieved a miraculous recovery by harnessing its advanced technology.
But beneath its renewed prosperity, a hidden threat looms—
“Tesseractors,” monstrous beings born from human malice and desire, bring supernatural disturbances to the city.
Only the voices of five girls, known as the “Witches’ Daughters,” can stand against them.
With songs imbued with magical power, these girls rise to fight the chaos and protect the fragile peace of their city.
In a world shattered by disaster, in a city that still stands—
a story begins of girls defying fate through the power of song.
